for connecting a CLI meter or second power supply. There are also fine and coarse

tuning controls and various variable resistors used to control the amplifier.

See Section 5 for a complete description of the PLC function.

5. System I/O Module:

The function of the System I/O Module is to provide the physical connection point

between the HPS/RFL GARD Pro system and the substation network. In addition to

this, the System I/O Module provides the following three timing functions:

o Optional GPS

o IRIG-B

o 1PPS (1 pulse per second timing signal)

An Optional GPS interface module (GPS time receiver) can be installed in the System

I/O Module. When it is installed, a GPS antenna must be connected to the SMA series

connector labeled “GPS” at the rear of the System I/O Module. When the GPS option is

installed, the BNC connectors labeled “IRIG-B’ and “1PPS” function as outputs and can

be used to drive equipment external to the HPS/RFL GARD Pro system. In this case the

IRIG-B output is un-modulated.

When the GPS built-in receiver is included, it resides as a piggy-back module on the

System I/O Module. The GPS receiver has to be connected to an externally mounted

antenna, provided as an accessory as shown below.

Figure 2-7. GPS Antenna

Also located on the System I/O Module is a six pin (RS-485) terminal block for use with

the DNP protocol. The six pin connector is always installed, but only used when DNP

is enabled over RS-485. The Ethernet port is used for remote management purposes.

An RS-232 port is also available for management.

6. Power Supply I/O Module:

The Powers Supply I/O Module has the following three functions:

o Connects the internal power supplies to the external power source(s)

o Provides major and minor alarm relay contacts

o Provides access to the digital interface (RS-449/X.21/V.35)

The digital interface is typically not used in PLC applications, but can be used to

connect to external equipment if required.

System Description

2.7 Controller Redundancy

2.7.1 Redundancy Controller Overview

The HPS/RFL GARD Pro system Controller Module offers a redundant operation mode when

used in a 6U chassis. When equipped with two Controller Modules, a GARD system can

disable a faulty module and transfer its functionality to the standby unit.

The redundant-mode control elements are effectively independent of basic GARD functions and

features. Redundancy subsystems monitor the condition of the module and take part in

determining which module is active.

When only a single Controller is present in a GARD chassis, the redundancy subsystem still

continues monitoring, however, it has no effect on the active state of the Controller. A single

module cannot be made inactive.

CAUTION

System Firmware version 2.1.0 or greater is required for Redundancy. Both controllers must

have matching system firmware versions for correct operation.

2.7.2 Rules of Operation

Two GARD Controllers present in the chassis in their dedicated slots facilitate the redundant

mode of operation. Only 6U chassis offer two controller slots. Redundant mode is not possible

with a 3U chassis.

When Both Controller slots are in use, Slot 11 has priority, while Slot 10 the standby

(Redundant) Controller has a short delay allowing the Main controller to become active first.

An “ACTIVE” module drives or controls the traffic within the chassis and configures other

submodules. An “INACTIVE” module does not output any signals onto mid-plane buses.

The basic rules governing swapping between the active and inactive state were designed to be

as simple as possible and to minimize disturbances to the system and prevent swapping into a

faulty or non-existent module.

A module cannot decide by itself to become active. It can become active only if the

other Controller fails or is disabled.

A failed module does not necessary become inactive. A swap to the other module may

happen only if the other module exists and is itself not in fault. A system with

Redundancy will block a swap into a faulty module.

There are no levels or degrees of fault conditions within a Controller module. A faulty,

disabled or non-existent module is treated the same way, since its state is not

trustworthy anymore.

System Description


2-12

An inactive Controller module always obtains its configuration for the chassis from the

active module – immediately after power-up and with continuing updates thereafter.

2.7.3 Implementation

Each GARD Controller contains a monitoring system, which monitors vital hardware signals

within the module. The CPU and DSP Processors monitor their own operations and interfaces.

A dedicated communications channel (“mirroring”) is used to copy system information, such as

configuration, from the currently active to the inactive module. This allows a newly installed

(and inactive) controller to become configured and ready to take over control if required.

Dedicated signaling channels on the midplane are used to convey faults and activity states of

the Controllers to their companion modules.

The active module has full control of the system, just as if it was the only one present. The

inactive module is idling in full operational condition. All drivers of its signals to the

backplane, Ethernet, etc. are disabled.

Besides the Controller, no “slave” module (channel module or functional module) in the GARD

chassis is aware of the presence of two Controllers, nor does it know which one is active. The

system operates the same way, regardless of which Controller is active.

If an out-of-bounds condition is detected within a Controller, an on-board fault condition is set.

Based on the rules of redundant operation, the active and inactive states may be swapped

between the two Controllers.

A Controller swap will affect GARD functionality momentarily while the “Inactive” controller

becomes “Active” and takes over control. Critical functionality will be restored within 1

minute, after the swap occurs.

2.7.4 Controls and Indicators

LED Indicator

LED indicator DS3, located at the card edge of the module, shows the state of redundancy

control of a Controller Module.

Mode Switch

A request to take the Controller module off-line (inactive) is made by moving card-edge switch

SW2 from “Normal” position to “Disable” position. This is equivalent to creating an on-board

failure, and will be indicated by the appropriate color of indicator DS3 (color will change from

Green to Orange).

If the rules of redundant-mode operation are satisfied, the Controller will become inactive and

System Description


2-13

the other module will take over.

It is important to remember that even if the Controller is in a failed state, it may be made

inactive only if a good companion module exists.

The rules of operation are designed to enforce the continuity of operation for the whole system.

Therefore, a module cannot be made inactive if the other Controller is in a fault condition or

does not exist.

Returning SW2 to the “Normal” position will clear the on-board fault condition. It does not

automatically make the module active. As per the rules of operation, the Controller Module

becomes active only if the other module fails or is disabled.

Configuration Mirroring

An inactive Controller module will retrieve (mirror) a copy of a system configuration from the

active module. This process starts immediately after power-up or reset of the Controller and

continues as long as the module remains inactive.

When manually forcing a switch between redundant controllers (for example, installing a new

module from a set of spares), the user should observe whether the first configuration transfer

completed, as indicated by DS3. If switched too early, the newly active Controller may be

configured incorrectly.

After first successful mirror, the inactive Controller will contain a copy of configuration that is

no more than one mirroring cycle behind the active module.

3.1 Introduction

This section contains installation instructions for the HPS/RFL™ GARD Pro™ system,

including unpacking, mounting, and interconnection wiring. For details on using the 50 and

100W Amplifier option with HPS/RFL GARD Pro system PLC applications See Section 5.6.

3.2 Unpacking

The HPS/RFL GARD Pro system equipment may be supplied as an individual chassis or may

be interconnected with other chassis or assemblies as part of a system. For unpacking

instructions see the following:

Paragraph Chassis type

3.2.1 individual

3.2.2 interconnected

3.2.1 Individual Chassis

HPS/RFL GARD Pro system terminals supplied as individual chassis are packed in their own

shipping cartons:

1. Open each carton carefully to make sure the equipment is not damaged.

2. After the chassis is removed from the carton, carefully examine all packing material to

make sure no items of value are discarded.

3. Make sure all modules are fully seated in the chassis. The machine screws securing all

I/O modules to the rear of the chassis should be fully tightened.

Caution

Pin damage from excessive force

Care should be taken when connecting individual modules to the mid-plane in either the 3U or

6U chassis. It is possible to damage the connecting pins if excessive force is used.

3.2.2 Interconnected Chassis

HPS/RFL GARD Pro system terminals ordered as part of a larger system may be

interconnected with other chassis and mounted in a relay rack or cabinet, or on shipping rails

for installation into a rack or cabinet at the customer's site. In such cases, the entire assembly is

enclosed in a wood crate or delivered by air-ride van:

1. If the equipment is crated, carefully open the crate to avoid damaging the equipment.

2. Remove the equipment from the crate and carefully examine all packing materials to

make sure no items of value are discarded.

Installation


3-2

3. Make sure all modules are fully seated in the chassis. The machine screws securing all

I/O modules to the rear of the chassis should be fully tightened.

3.3 Mounting

After unpacking, HPS/RFL GARD Pro system equipment must be securely mounted, following

the instructions in the following paragraphs. Use the procedure that suits your equipment:

- individual chassis

- interconnected chassis installed in racks or cabinets

- interconnected chassis mounted on shipping rails

3.3.1 Individual Chassis

HPS/RFL GARD Pro system terminals housed in individual chassis have two mounting ears

(one on each side). Hole sizes and spacing’s conform with EIA standards so the HPS/RFL

GARD Pro system can be mounted in any standard 19-inch rack or cabinet. Complete

mounting dimensions are shown in the following figure.

Installation

3.3.2 Interconnected Chassis Installed in Rack or Cabinet

Systems mounted in racks or cabinets at the factory are to be placed in position and then bolted

to the floor or wall, as appropriate, to secure the equipment in place. The type of hardware used

will depend upon the particular surface to which the rack or cabinet is being mounted. Because

of this, mounting hardware is not supplied with the rack or cabinet.

3.3.3 Interconnected Chassis Mounted on Shipping Rails

For delivery, equipment is mounted on shipping rails. To remove the shipping rails and mount

the equipment in a rack or cabinet, proceed as follows:

1. Place the equipment as close to the front of the rack or cabinet as possible, with the rear

panels of the equipment facing the front of the rack or cabinet.

2. Remove all the screws securing the shipping rails to the equipment.

3. Slide the equipment into the rack or cabinet.

4. Install and tighten screws to all panels to secure the equipment in place.

3.4 Ventilation

The specified operating temperature range for HPS/RFL GARD Pro system equipment is -20oC

to +70oC (-4

oF to +158

oF). Operation at higher temperatures may affect system reliability and

performance. Systems installed in enclosed cabinets should be ventilated to keep the

temperature inside the cabinet within limits.

CAUTION Improper wiring can cause false trips

Normal system operation switching of relay contacts can produce voltage spikes. These spikes

can travel down the relay output leads and induce currents in other leads. These induced

currents can result in false trips. To reduce this possibility, use a shielded twisted pair for each

input lead, and ground the shield at the HPS/RFL GARD Pro system chassis only. As an added

precaution, do not bundle input, output, and power leads into the same harness, and keep them

as far apart as possible.

3.5 System Module I/O Connections

The HPS/RFL GARD Pro system has a system I/O module used for timing and remote access

functions.

Make connections as required as shown below.

3.5.1 Ethernet connection for local access

The front Ethernet port provides access to perform the initial setup of HPS/RFL GARD Pro

system. The built-in DHCP server assigns an IP address in the 192.168.1 subnet. With this

access the user can assign parameters such as the network IP address for the rear Ethernet port.

Note:

To access the HPS/RFL GARD Pro system remotely the connection must occur through the

rear port.

3.5.2 Ethernet connection for remote access

The rear Ethernet Port provides the means to connect the HPS/RFL GARD Pro system with the

TCP/IP network. The connection to the TCP/IP network must occur through the rear port.

The rear port provides DNP3 to pass data to the master and TCP/IP access for system

maintenance.

3.5.3 RS-485 connection for DNP3

The HPS/RFL GARD Pro system DNP3 slave is required to communicate with the DNP3

master over the rear Ethernet port and/or the RS485 2-wire/4-wire interface. Both interfaces

may be active for DNP use at the same time. For example one DNP master can access the

HPS/RFL GARD Pro system through RS485 and up to two other DNP masters may access

through the rear Ethernet port.

When using the RS-485 protocol, connections are made to the System I/O Module on the rear

of the HPS/RFL GARD Pro system chassis as shown below.

different networks.

3.5.4 RS-232 connections (Management port)

This port provides an IRIG-B reference signal from the HPS/RFL GARD Pro system. See

section 3.7.3 for more information.

3.5.5 IRIG-B timing connection

IRIG-B is part of a timing standard that varies primarily by rate. The timing for IRIG-B is a

100 Hz pulse rate which the HPS/RFL GARD Pro system can supplement with an optional GPS

signal.

The timing maintains the system clock so the time of remote devices accurately reports the

messages sent back to the controller. The standard was established before GPS so industries

that need properly correlated times adopted one of the IRIG timecodes. IRIG-B is common in

the data handling systems, communication systems and telemetry systems such as power

industry.

Installation


3-9

IRIG-B is unidirectional with signals sent by the master to the slave devices to maintain a

uniform system time.

Find the settings for the IRIG-B in HPS/RFL GARD Pro system with and without the GPS in

section 3.7.

3.5.6 The 1 – Pulse per second timing connection

The 1-Pulse per Second signal provides a timing pulse each second. The shape of the pulse

makes the signal more precise than one second and can be a few microseconds or better. The

internal clock provides the timings less than a second with the 1-PPS signal providing system

accuracy.

The length of the transmission line and the resulting pulse distortion can affect the accuracy of a

signal.

3.5.7 GPS antenna connection (optional)

The optional GPS antenna takes the system timing from the GPS satellites.

When the GPS option is installed, the BNC connectors labeled “IRIG-B’ and “1PPS” function

as outputs and can be used to drive equipment external to the HPS/RFL GARD Pro system. In

this case the IRIG-B output is un-modulated.

3.6 Rear I/O, Alarm Relay and Input Power Connections

3.6.1 Rear I/O Terminal Block Connections

The terminal blocks on the rear of the HPS/RFL GARD Pro system chassis are conventional

screw-type barrier blocks. Wires can either be stripped or terminated in spade lugs, depending

on local practice. HPS/RFL recommends that wires be terminated by #6 ring lugs as an extra

safety precaution.

3.6.2 Alarm and Alert Relay Connections

The HPS/RFL GARD Pro system chassis has two SPDT (Form C) relays mounted in the Power

Supply I/O module. The terminals are labeled as shown on the following page. The Major

Alarm relay terminals are on the left of the figure and the Minor Alarm relay terminals are on

the right. The contacts are rated 100mA, 300Vdc, resistive load. The alarm relays will respond

to alarm and alert conditions. The functionality can be customized by the user as required.

Under normal operating conditions when the alarm conditions are healthy the relays are

energized, in an alarm or alert state the relays will be in the de-energized position.

Note All relay contacts are labeled in the de-energized position.

section before attempting to connect input power.

Installation


3-11

3.6.3 Chassis Ground Connections

A protective earth stud at the lower right rear of the HPS/RFL GARD Pro system chassis is the

main ground for the terminal.

MAJOR MINOR

Protective Earth Stud

Figure 3-7. Chassis Grounding Location

Grounding is accomplished by connecting a wire 6AWG or larger between this protective earth

stud and rack ground. The grounding wire should be kept as short and straight as possible, to

keep its resistance and inductance to a minimum.

Before attempting to make power connections, make sure the HPS/RFL GARD Pro system

terminal is equipped with a power supply designed to operate at the available input supply

voltage. This can be determined by checking the power supply label on the exterior of the unit,

as shown in FIGURE 1-2. If an external power supply is being used, check the markings on the

external power supply. If the wrong voltage is connected to the power supply, component

damage will result.

3.6.4 Input Power Connections

WARNING!

Electric shock, equipment damage

Install individual double pole disconnects between the building or station battery supply and

HPS/RFL GARD Pro system power supply. This must be done for both the main and back-up

supply.

CAUTION

Damage to the power supply

Power supplies are not hot swappable. Switch off power at the appropriate power supply

before installing or removing power supplies from the HPS/RFL GARD Pro system chassis

After all other connections have been made to the HPS/RFL GARD Pro system, input power

connections can be made to the Power Supply I/O at the rear of the chassis.

Before proceeding to connect power to the HPS/RFL GARD Pro system ensure that the main and

Installation


3-12

redundant power switches on the rear of the unit are in the “OFF” position and that the power wires

to be installed are disconnected at their source.

Make input power supply connections for all power supplies installed. Depending on the

number of power supplies installed the locations of the connections for each power supply are

shown in the following table:

Number Location at Front Terminal Block Label at Rear

1 Power Supply 1 Power Supply 1

1 Power Supply 2 Power Supply 2

2 Power Supply 1 and Power Supply 2

Input power connections can be either DC station battery voltage (24, 48, or 250VDC) or AC

voltage (125VAC or 220VAC), depending on which power supplies are installed in the chassis.

Station battery positive goes to the “+” terminal and station battery negative goes to the “-“

terminal. If AC input power is used, connections are made to the “+” and “-” terminals and the

polarity markings can be neglected.

Before connecting the power at its source and switching on the HPS/RFL GARD Pro system, check

the following:

Is the HPS/RFL GARD Pro system grounded correctly?

Is the installed HPS/RFL GARD Pro system power supply designed to operate at the

available input supply voltage?

Is the polarity of the supply power correct?

If installed in an enclosed cabinet, is the unit ventilated correctly?

Power connections may now be made to the HPS/RFL GARD Pro system.

System Configuration Section 4.

4.1 Connecting a Laptop and Setting IP Addresses

The HPS/RFL™ GARD Pro™ system is delivered with pre-set IP addresses. The front port IP

address is fixed, and factory set to 192.168.1.1 with a subnet mask of 255.255.255.0. The rear

port IP address is configurable.

4.1.1 Front Ethernet Port

Caution:

DO NOT plug this port into a LAN. You cannot have more than one device with the same

address on a network. The front port is strictly for direct connection to a Laptop PC.

The IP Address assigned to the front port is https://192.168.1.1 for every HPS/RFL GARD Pro

system chassis. The Laptop should have an IP Address on the same subnet (192.168.1.x) as

described below. The front port has no default gateway configured, so it is not routable. This

is done for security purposes

RFL™ GARD Pro™ System

Standard Ethernet Cable

Laptop/Notebook PC

RJ-45 Ethernet PortRJ-45 Ethernet Port

IP Address: https://192.168.1.1

Figure 4-1. Front Ethernet Port

Note

All HPS/RFL GARD Pro system front Ethernet ports are preconfigured to an IP address of

192.168.1.1 at the factory, and cannot be changed.

Connect a standard Ethernet Cable from the RJ-45 Ethernet port on your PC to the front RJ-45

Ethernet port on the HPS/RFL GARD Pro system as shown above.

DHCP (Dynamic Host Configuration Protocol) is available when connecting to the front

Ethernet port on the HPS/RFL GARD Pro system with a laptop or PC. DHCP will obtain the

parameters necessary for operation in a local IP Network with the front port. This protocol

greatly reduces the system administration workload, allowing addressing setup with minimal or

no manual configuration.



4-2

Following is a step for step procedure to configure a Laptop for DHCP using the Windows® 7

operating system. Remember that operating systems are subject to updates and can vary

slightly.

4.2 Configuring a PC Using DHCP and Static IP

4.2.1 Configuring a PC using DHCP

1. Click on the “Internet Access icon” in your desktop system tray. The example shown is

for an electrical connection; a wireless connection would be a succession of bars.

Figure 4-2. Internet Access Icon

2. Click on “Local Area Connection”

Figure 4-3. Local Area Connection

4.2.2 Configuring a PC using Static IP Addresses

Instructions on setting static IP addresses are detailed below.

1. Follow the previous screens until you reach the screen above. Select “Use the

Following IP Address” and enter the IP and Subnet Mask address as shown below.

Figure 4-7. Use the Following IP Address



4-5

2. Click “OK.”

3. Since you have changed the IP address of your PC, you will not be able to access the

network that it was previously connected to. This includes the internet. A normal side

effect of this is that the homepage your browser is configured to open on at startup will

not load successfully. To access the HPS/RFL GARD Pro system for maintenance,

enter 192.168.1.1 in the address bar.

Following are instructions on logging onto the HPS/RFL GARD Pro system web server.

4.3 First Time Login to the HPS/RFL GARD Pro System Web Server

4.5 Web/SCP Server

The HPS/RFL GARD Pro system has three User Interface communication ports; a front RJ-45

Ethernet port, a rear RS-232 port, and a rear RJ-45 (electrical or optical) Ethernet port. Field

upgrades to the HPS/RFL GARD Pro system are normally done utilizing the on-board secure

FTP/SCP Web Server.

Note:

Field upgrades must be done through the front Ethernet port.

The rear RS-232 port is for HPS/RFL use only.

Menu location: System Management > Web/SCP

The Web/SCP Server Configuration page is shown below followed by a detailed description of

the various options.

1 2 3

4 5Active when “RFL Self

Signed” is selected above

Active when “Custom”

is selected above

Figure 4-15. Web/SCP Server

1. SCP Server: This will enable or disable the Secure Copy Protocol server on the

HPS/RFL GARD Pro system front Ethernet port. This is disabled by default, and is

disabled after every power-cycle or reboot of the HPS/RFL GARD Pro system

controller module regardless of the setting.



4-16

Note:

Enabling the SCP server will only last until the controller reboots. Before a field

upgrade is possible the SCP server must be enabled, it will be disabled during the

upgrade process since power cycling is required.

2. HTTP/HTTPS: The HPS/RFL GARD Pro system web server can be configured to use

either hypertext transfer protocol (HTTP) or https over a secure sockets layer (HTTPS),

HTTP is the default. When using HTTP without a secure sockets layer the entire web

page and form content is sent in clear text. Passwords and usernames are obscured to

prevent the casual user from seeing them in packet captures, but this is by no means

secure. When using https all traffic between the browser and server is encrypted.

The server on the HPS/RFL GARD Pro system may be configured to listen to HTTP

requests on the front port. The rear port must be https and the front port can be either.

The option to listen to none or turn off the server is available only for the rear port. The

front port must be configured for at least one protocol.

3. HTTPS Certificate/Key Pair: In order to perform the security tasks involved the

HPS/RFL GARD Pro system needs a certificate file and private key file, both of which

must be PEM (Privately Enhanced Mail) encoded. The unit comes with an HPS/RFL

self-signed certificate. You may choose between using the built in certificate and key or

a custom certificate and key that you upload.

Table 4-3 Security Levels

Method Pros Cons

HTTP Simple to use. Insecure.

HTTPS with HPS/RFL Cert.

Secure.

User must remember to use HTTPS instead of just an IP address in the address bar of the browser. Private key is the same for all HPS/RFL GARD Pro system browsers and therefore may be considered compromised.

HTTPS with custom Cert.

Most secure. User must remember to use HTTPS instead of just an IP address in the address bar of the browser. User has to generate his/her own certificate and key pair.

When using the HPS/RFL self-signed certificate the browser will not trust the signing

certificate authority by default, and will therefore indicate a problem with the certificate.

You may bypass this warning and force the browser to continue, but if you do so you

will have to do it again next time you log in. The user should set up the browser to trust

the HPS/RFL GARD Pro system certificate authority. To do this, follow the appropriate

procedure based on your browser.

For Internet Explorer (page down for Chrome or Firefox)

4. Download Certificates (Active when “RFL Self Signed” is selected)

4.16 DNP3

4.16.1 Description

DNP3 is a communications protocol to allow automatic collection of data from remote devices.

This provides communication for slower networks and Ethernet. Communications on an as-

needed basis reduces the overhead required.

The System Firmware version must be 2.2.0 or greater.

DNP (Distributed Network Protocol) is used by a “master” station (control center) to poll

multiple “slave” devices for status, usually over a wide geographic area. Since many devices

are involved and each device has many “points” or values, a class-based polling system is

applied, similar to an RBE (report-by-exception) scheme. Class 1 polls are done most

frequently, on the most important data, Class 2 less frequently, and Class 3 even less frequently.

When a Class 1, 2 or 3 poll is executed, the “slave” device only returns those values which have

changed state since the last poll. A Class 0 poll returns all values regardless of whether they

have changed state or not. For more information on Data Points see section 4.16.1.2.

4.16.1.1 Overview of HPS/RFL GARD Pro System DNP3

The HPS/RFL GARD Pro system controller board has factory installed software that allows the

user to take advantage of the robust and flexible features of the DNP communications protocol.

Once configured, the HPS/RFL GARD Pro system will communicate with up to two TCP/IP

and one RS-485 remote DNP master computers. The remote master computers poll the

HPS/RFL GARD Pro system for data.

Note 1: For change events, SOE Trigger points will be reported with timestamps synchronized

to the HPS/RFL GARD Pro system clock and as reported in the Sequence of Events report.

Note 2: To be recorded as a DNP change event, the duration of the event must be a minimum

of 1 millisecond for SOE Trigger points or 50 milliseconds for HMI Out and HMI In.

Note 3: Functional Module Point labels can be configured through the appropriate DNP

configuration pages. To change the default labels for Functional Module Points navigate to the

appropriate tabs on the Configuration > DNP > point type pages.

The System Logic Point labels can be changed in the appropriate Configuration > SOE and

Advanced > HMI pages.

To make use of the DNP feature the user must configure the HPS/RFL GARD Pro system

appropriately using the “DNP3 Configuration” web page; Configuration > DNP > General.

This sets up the communication parameters allowing the HPS/RFL GARD Pro system to

connect with other devices.



4-61

Once the DNP configuration page is set other parameters such as the “Point list setting” web

pages can be configured.

Note: DNP will not be functional until at least one DNP point is enabled.

To reduce polling traffic, the GARD Pro can be set to send unsolicited messages to any of the

DNP3 masters. Unsolicited messages are sent when a binary object changes state or an analog

value changes by more than a user adjustable deadband setting. The unsolicited message

capability is disabled by default and must be enabled via an “Enable Unsolicited Messages”

command from the DNP master.

Note:

Since the unsolicited messaging setting of the GARD Pro is not stored in NVRAM, it must be

enabled by the DNP Master each time the GARD Pro is power-cycled."

4.16.1.2 DNP3 Features

The HPS/RFL GARD Pro system provides the following features to aid managing the system.

4.16.1.2.1 Data Point Refresh Time

In some cases the refresh rate of DNP points may be slower than the actual event duration.

This means it is possible that events which occur within the refresh time will be missed and not

recorded as a DNP change event.

In the HPS/RFL GARD Pro system the refresh time for SOE Trigger DNP points is 1

millisecond. For HMI In and HMI Out the refresh time is 50 milliseconds.

In order for an event to be recorded as a DNP change event, the duration of each state must be a

minimum of 1 millisecond for SOE Trigger points or 50 milliseconds for HMI Out and HMI In.

4.16.1.2.2 Data Point Index manual assignment

Manually assigned data point indexes is provided as an alternative to auto assigned. This

requires the user to manually assign each data point index. Indexes can be freely assigned

within an object type as long as there are no duplicates indexes.

Manual mode also includes a default index assignment option which applies a default index for

each point. Default indexes for points sourced from installed modules, where available, are

based on the slot number and location.



4-62

4.16.1.2.3 Data Point Index manual default assignment rules

The DNP data point index is a sequential number assigned to a data point of a particular Object

Type. Each data point within an Object Type has a unique data point index.

Index rules apply to each object type independently.

Each physical slot has 100 points reserved in the index space.

Index ranges for each slot are as follows:

o Slot 1 = 200-299

o Slot 2 = 300-399

o Slot 3 = 400-499

o Slot 4 = 500-599

o Slot 5 = 600-699

o Slot 6 = 700-799

o Slot 7 = 800-899

o Slot 8 = 900-999

o Slot 9 = 1000-1099

o Slot 10 = 1100-1199

Default index ranges by slot are divided by front, rear top/right and rear bottom/left. The

divided ranges are as follows:

o Front: n*100 + 0…63 (64 total)

o Rear: n*100 + 64…99

Within the rear: Top/Right: 64-81 (18 total), Bottom/Left: 72-99 (18 total)

4.16.1.2.4 Data Point Index auto-assign rules

In auto implementation the data point index is assigned when the points are enabled in the point

list settings. This means that the data point indexes will change as points are enabled or

disabled.

Example of auto-index numbering: If data point 1, 3 and 5 are enabled the device will assign

these with an index of 0, 1 and 2. If data point 2 is added data point 3 and 5 will become index

2 and 3.

When using auto index assignments a priority rule is used to sequential assign index numbers

within a point type. Priority is determined by the source of the point and the slot number and

location. The priority rules are as follows:

System Logic Points (SOE triggers, HMI bits)

Lowest Slot Number

Front Slot Position

Rear top/right to Rear bottom/left

Caution:

Switching to manual retains the existing the auto-index assignments.

If you switch back to auto this will renumber all index assignments according to the auto-assign

rules.

Configuration > DNP > Type 30 – Analog

This page lists any DNP Type 30 Analog points available for reporting. This option is only

available when supporting modules are installed. Points from different sources are organized on

separate tabs.

4.16.2.6.1 Deadband:

Specifies the integer value, in the units of the particular point, by which an analog value must

change before it will be reported at the next poll or generating an unsolicited message, if

configured.

The units used for the deadband setting depend on the measurement type. For example,

Reflected Power is measured in percent. So a deadband setting of 20 requires the Reflected

Power to change by +/- 20% before the GARD Pro will report a change in value to the DNP

master.

4.17 SNMP

4.17.1 Description

SNMP is supported on GARD Pro system firmware versions 2.2.0 or greater. The version can be

read on the System Management > Inventory & Version Info page. This provides an SNMP Agent

which allows RTC (Real Time Clock) time stamped v2c SNMP Trap Messages to be sent via

the rear Ethernet port. These messages are triggered by changes in the HMI output bits as

defined by the HPS/RFL GARD Pro system logic. In addition SNMP v3 GET functionality is

supported, allowing read access to the GARD Pro system parameters.

The SNMP Agent does the following:

Provides SNMP Traps and Transmits RTC based time stamped alarms and other

events to the customer’s software management equipment based on custom

HPS/RFL GARD Pro system logic HMI output bit changes.

Supports up to five management IP addresses.

Supports the GET operation to view the values in the MIB.



4-79

4.17.1.1 Traps

When the Trap Agent receives an HMI output change notification, it produces one SNMP Trap

Message for each HMI output bit change, and sends that message to all enabled SNMP

management IP addresses. One bit change mask can have from one to 64 bits set, with all

monitoring computers enabled the Trap Agent generates up to 320 Trap Messages.

Each Trap Message contains the following data:

• The HMI-OUT bit number

• The HMI-OUT bit value (after the change)

• The HMI-OUT bit label

• The RTC based time -stamp

• The User System Labels as set in the System Configuration page. They are default

under the names shown but can be labeled at the user’s discretion. "Chassis

Identification" through "Appropriate Use Warning" are user-entered labels.

HMI output bits are completely defined by the HPS/RFL GARD Pro system logic. Custom

logic to generate HMI output bit changes facilitates reporting of events important at the

monitoring stations.

Note: Contact RFL for custom logic applications.

4.17.1.2 Get

SNMP “Get” Functionality

SNMP Get uses SNMP v3 authenticated access to view GARD Pro system parameters. No

parameter changes are permitted. The parameters available for viewing are defined in the

SNMP MIB file. See SNMP MIB in 4.17.3 for a list of the MIBs scalar and table structure.

Note: This software supports “get” functionality only.



4-80

4.17.1.2.1 Changing the password

The default SNMP v3 username and password is set in the factory to the following:

Login: Admin

Password: Admin

RFL advises you to change the default password to a unique value. Change the password using

the following steps:

1. Navigate to the password change screen.

System Management > Users > Change Password

2. Enter the current password in the “Current Password:” field.

3. Enter the new password in the “New Password” field. The password must follow these

requirements:

Password must be between 8 and 14 characters long, and must contain at least three of

the following character types: uppercase letters, lowercase letters, numbers, and special

characters. Allowed special characters are ~!@#$%^_-+=[].?

4. Reenter the new password in the “Confirm New Password” field.

Power Line Carrier


5-1

Power Line Carrier Section 5.

5.1 Power Line Carrier Function

The HPS/RFL™ GARD Pro™ system with Power Line Carrier (PLC) is a Single Function

PLC protection unit. The PLC function consists of two plug-in modules: A digital module

which plugs into the front of the chassis, and an Analog module which plugs into the rear of the

chassis. Both modules can be installed in a 3U or 6U the HPS/RFL GARD Pro system chassis.

The single function channel can be configured for two modes of operation: FSK (Frequency

Shift Key), or On/Off. In FSK mode, it can be configured to support either 2F or 3F operation.

In On/Off mode, it can be configured to support both Normal Checkback and Hard Carrier

Checkback.

In addition to performing the normal PLC functions, the unit will monitor the transmit interface

to measure transmit power, reflected power, trans-hybrid loss, and receive signal strength.

5.1.1 FSK Operation

As stated above the HPS/RFL GARD Pro system with PLC supports two FSK operational

modes: 2F and 3F.

In 2F operation a guard tone is located at a fixed deviation below or above the channel center

frequency. At the occurrence of a trip, the tone shifts to the opposite side of the channel center

frequency.

In 3F operation a guard tone is located at the channel center frequency. One of two following

trips can occur causing the tone shift a fixed deviation:

1. below the channel center frequency

2. above the channel center frequency

The performance of 2F and 3F operation is defined by the Maximum Trip Transport Delay,

Dependability and Security.

- Maximum Trip Transport Delay: The time between the following two events:

1) When the unit transmitter is notified of a trip event through the Logic Bus, until

2) The unit receiver on the other side of the link writes the trip event into the Logic Bus

status registers.

More specifically, it is defined as the delay between the Logic Bus frame reception

interrupt which contains the trip event information until the status register is written in

the receiver. The Maximum Trip Transport Delay is defined by the three operational

configurations for the following:

o 2F operation in TABLE 5-1.

o 3F operation in TABLE 5-2.

See FIGURE 5-1 Minimum Channel Spacing (FSK).

- Dependability: The probability that a trip event will be successfully communicated to

the other end of the link within the Maximum Trip Transport Delay as a function of the

signal to noise ratio of the link.

Power Line Carrier


5-2

- Security: The probability that a false trip event will be declared at the receive end of

the link as a function of the signal to noise ratio of the link.

5.1.2 On/Off Operation

On/Off operation defines the absence of a tone (Off) to be the guard condition. The presence of

a tone (On) is the block condition. Since there is no tone present under normal non-block

operating conditions, no receive AGC functions may be performed. Therefore, the nominal

receive signal level is determined during deployment, and the operating parameters of the

system are set accordingly and maintained in non-volatile memory of the Module.

In order to determine that the link is operating normally, a checkback process is used to test the

link. For the purposes of checkback, the Module at the near end of the link is defined as the

Master and the Module at the far end of the link is defined as the Remote. During checkback, a

pre-defined sequence of On/Off states (checkback codes) is transmitted by the Master to the

Remote which responds with an acknowledgement on a successful reception.

The Remote responds in one of two ways depending on how the Master terminates its

transmission of the Checkback Code. One of two responses will occur:

1) Hard Carrier Mode: If the Master leaves the tone on for 5 or more seconds after the

last bit of the Checkback Code, the Remote responds in Hard Carrier Mode. In Hard

Carrier Mode, the Remote responds by transmitting a tone to the Master for a pre-

defined length of time.

2) Normal Mode: Otherwise, the Remote responds in Normal Mode. In Normal Mode,

the Remote responds by transmitting a pre-defined sequence of On/Off states (called the

Acknowledgement Code) to the Master.

Four Hard Carrier transmitted codes and two received codes can be programmed into either the

master or remote units. Operation from either end is possible.

Checkback may be initiated automatically by either the Master or the Remote. It may also be

initiated manually by the user. Remote initiation is accomplished by sending a specific code to

the master. This code tells the master to initiate a test sequence. This code is not available as a

response code from remotes for normal tests.

On/Off Systems transmit and receive on the same frequency. Therefore, the local receiver

cannot differentiate between remote transmissions and local transmissions. In addition,

checkback sequences are detected as a sequence of block events. The local receiver will report

all block events through the Logic Bus interface whether the source is from local transmissions,

checkback sequences, or real block events. It is up to the logging mechanism in the Logic

Controller to filter out unwanted SOE reports. To aid in this filtering the module will indicate

that a test is in process through a bit on the logic bus that is active while a test is ongoing in a

master or while an incoming code is detected in a remote.

The performance of On/Off operation is defined by the Maximum Block Transport Delay,

Dependability and Security. These are the same definitions for FSK in 5.1.1 with the exception

the Maximum Block Transport Delay for On/Off operation is defined by the three operational

configurations given in the table below, TABLE 5-3.

Power Line Carrier


5-5

Table 5-3 On/Off Block Transport Delay and Channel Spacing

Configuration Settings Nominal Block Transport Delay

Minimum Permissible Channel Spacing

Nominal Receive Bandwidth: 500 Hz 5 ms 1 kHz

Nominal Receive Bandwidth: 1000 Hz 3 ms 2 kHz

Nominal Receive Bandwidth: 1500 Hz 1.5 ms 3 kHz

Security & Dependability do not really apply to an On/Off unit. The unit should issue a block

received output any time there is sufficient energy in the receive band regardless of total SNR.

Instead of security, adjacent channel rejection is probably more relevant. Dependability of an

On/Off unit should remain constant as noise increases until the input circuits (or DSP numbers)

saturate.

5.1.3 Compatibility Issues for PLC Module Software

For users of older GARD Systems:

The PLC Module Software is used with the GARD Custom System Logic to meet each user’s

specific application needs. The PLC Module Logic and HPS/RFL GARD Pro system PLC

System Logic were updated and both logic versions need to agree.

Beginning in October 2011, new PLC software (indicated as V17) was released to improve the

functionality of the unit. Although these changes are transparent to the end user, certain

compatibility issues with the new PLC software and older System Logic should be noted.

Units shipped after October 2011 have updated default PLC System Logic, however if GARD

units are modified in the field and have either new PLC software with old PLC System Logic or

the reverse, the units may not perform as expected. The two scenarios are described below:

Table 5-4. Compatibility Issues for PLC Module Software

New PLC software/Old system logic New System Logic/Old PLC software

The function to disable the Transmitter from an external input will not function.

The security against unwanted operations

in FSK mode will be slightly reduced.

The unblocking feature in FSK will not work.

The RX SNR alarm will not work.

Because of these differences, care must be taken when swapping modules or reusing the

“Whole Chassis Configuration” files from different versions.

The following is invalid:

Transferring existing PLC Digital Modules with V13 software (or earlier) into

units with updated System PLC Logic (V17 software).

Transferring new PLC Digital Modules (V17 software) into existing units with

previous System PLC Logic revision, other than V17.

Power Line Carrier


5-6

Loading any whole chassis configuration files not identified as V17 (-A17-) into

units with new V17 PLC Digital Modules.

Loading whole chassis configuration files with the new revision into units with

existing PLC Digital Modules (version V13 or earlier).

Identifying revision levels:

PLC Module software and System Logic:

Through the web interface, System Management > Inventory and Version Info

The revision of a System Logic or Whole Chassis Configuration file can be determined by its

file name. See the example below, taking note of the “17” identification after the revision

letter.

Logic Filename: GARD3U175_00146_001_A17.EDN,.TXT,.DSN.PDF

Whole Chassis Configuration Filename:

GARD3U175_00146_001_A17_C01.ZIP

When creating new Whole Chassis Configuration Files verify the version of the logic loaded

into the unit. If the unit has V17 System Logic installed then mark the filename with a V17

indication. This file should only be loaded into units with V17 PLC Module software.

RFL will modify any logic designed for the previous PLC software version (V13) and earlier

PLC software to work with version 17. Please do not hesitate to contact HPS/RFL for technical

support at 973-334-3100 ext 226 or via e-mail at [email protected]

CAUTION

Electro Static Discharge damage

The HPS/RFL GARD Pro system PLC Module set is a Static Sensitive Device. Persons

working on this equipment must observe Electro Static Discharge (ESD) precautions. As a

minimum you must use anti-static devices such as wrist straps and floor mats and leave

modules in their anti-static bags until they are ready to be installed.

Before proceeding to make connections to the Analog PLC Module, ensure that all the modules

in the chassis are correctly seated:

1) Remove the front panel to the HPS/RFL GARD Pro system chassis

2) Using minimal force, remove and re-seat all front panel modules.

Typically when a single PLC module set is used they are installed in a 3U chassis, however if

more than one PLC is required a 6U chassis is needed. Depending on the configuration and

power consumption limits a second power supply may be required. Details on external

connections to a second power supply are shown in Section 5.8. Following is the PLC Analog

Module as it would appear in the rear of a 3U chassis.

The PLC carrier level indicator RX value is displayed on the meter. The value displayed

represents a variance in received signal level from the initial signal level when the unit was

commissioned. The meter is normally factory installed and MUST be used in conjunction with

the Digital PLC Module (500455-1). The meter is connected to J6 on the Digital PLC Board.

There are two potentiometers for Offset and Scale. Normally no adjustments are necessary as

the CLI Meter is calibrated before leaving the factory, but if tuning is required instructions are

given in Section 5.5.5.1.

to 15dB for proper operation. The range is from 0dB to 100dB in 1dB increments.

2. RX AGC Setpoint: Determines the headroom allowed in the analog section of the

receiver when commissioned. Should be set to 30.

3. Minimum Rx Level: Determines the minimum point at which a trip can be

instantaneously received. The FSK RX threshold sets the absolute level, this sets the

instantaneous level. The range is 6 to 100 in increments of 1. Must be set to 11.

4. Trip Rx Threshold: This setting determines the minimum amount of energy (below

the commission point) at which tripping is allowed. It should be set to 25 for most

applications. The range is 0 to 100 in increments of 1.

Power Line Carrier


5-15

Continued……

5. Guard Rx Threshold: This setting determines the minimum amount of energy (below

the commission point) at which the guard signal is allowed. It should be set to 35 for

most applications. The range is 0 to 100 in increments of 1.

Note: When 1 watt Guard and 10 watt Trip transmit levels are NOT used (not

common) it may be desirable to change these settings. Ideally the difference between

the Trip and Guard threshold settings should be equivalent to the difference between

the Trip and Guard transmit power levels in dB. For example with a 10W/10W system

a “Guard RX Threshold” setting of 25dB, the same as the “Trip RX Threshold”, is

appropriate as there is no difference between the Trip and Guard transmit levels.

Note: The Trip Threshold setting in versions earlier than PLC firmware v24 is called

the "RX Threshold" but works the same.

Note: The Guard RX Threshold setting became available with PLC firmware v24.

Previous versions of firmware do not have this setting available.

CAUTION Changing the following bit range settings will affect system logic.

These settings should not be changed unless directed by RFL.

Refer to the System Logic PDF for help with the following settings.

5.4.1.6 FSK Test

This page will allow the user to force the carrier signal to different frequencies. This can be

useful in troubleshooting, tuning auxiliary coupling equipment or measuring levels etc. Forcing

the carrier will cause the PLC module to go into minor alarm. This reminds the user that the

PLC is not in its “normal” state.

CAUTION:

Leaving the carrier on a different frequency will affect the operation of the unit and protection

of the system.

Always put the carrier back into the normal state before leaving the unit.

7. RX Block Frequency: Sets the RX block frequency from 30kHz to 500kHz in


8. RX Bandwidth: There are three settings available in On/Off mode: 500, 1000 or

9. Block Hold Timer: This setting delays the dropout of the block output after the

blocking signal is lost. This delay can be set in the range of 0 to 50ms in increments of

1ms. The recommended default setting is 10ms. The timer increases the reliability of

the blocking receiver by preventing an intermittent loss of carrier. This loss can be

caused by arc gap flashover which would allow the protective relay to over-trip for an

external fault condition.

Start/Stop Logic:

10. Start Logic: Sets the polarity for the “Stop 1” and “Stop 2” input contacts. Can be set

to Normal or Inverted. When set to Normal, the contact is active when the station

battery voltage is present, and is inactive when the station battery voltage is not

present. When set to Inverted, the contact is inactive when the station battery voltage

is present, and is active when the station battery voltage is not present.

11. Start Logic – Start 1 or Start 2: Selects whether the “Start 1” and “Start 2” contacts

are ANDed or ORed. The options are “And” or “Or.”

12. Stop Logic: Sets the polarity for the “Start 1” and “Start 2” input contacts. Can be set

to Normal or Inverted. When set to Normal, the contact is active when the station

battery voltage is present, and is inactive when the station battery voltage is not

present. When set to Inverted, the contact is inactive when the station battery voltage

is present, and is active when the station battery voltage is not present.

13. Stop Logic – Stop 1 or Stop 2: Selects whether the “Stop 1” and “Stop 2” contacts

are ANDed or ORed. The options are “And” or “Or.”

5.5 Power Line Carrier Commissioning

5.5.1 Introduction

The HPS/RFL GARD Pro system with PLC is factory-configured as a 50-ohm power line

carrier terminal. If 50-ohm termination is being used, then the Receiver Calibration is typically

the only commissioning procedure required in the field.

This section is broken down into two parts: User interface calibrations, which require a PC

connected to the management port of the HPS/RFL GARD Pro system PLC and rear module

adjustments, which are made on the amplifier module. Below is a complete list of calibrations

and adjustment procedures:

- User-interface calibrations:

Receive level calibration (user interface, field calibration procedure)

Transmit power level measurement calibration(user interface, factory-set at 50-ohm)

Reflected power measurement calibration (user interface, factory-set at 50-ohm)

- Rear-module adjustments:

Impedance adjustment (rear module, factory-set at 50-ohm)

Transmit power level adjustment (rear module, factory-set at 50-ohm)

Transmit fail level adjustment (rear module, factory-set at 28.5dBm, 50-ohm)

Skewed hybrid tuning (rear module, factory-set at 50-ohm)

The following pages will describe calibration procedures initiated through the user interface:

WARNING!

Not using the correct dummy load will affect calibration.

When running the TX Monitor or Reflected Power Monitor level procedures the transmitter

MUST be terminated into a 50Ω non-inductive dummy load.

Power Line Carrier

5.5.2 Calibrations through the User Interface

Menu location: Test > Calibrate.

The following example web page is for FSK applications. ON/OFF applications are similar but

not shown. As shown below, clicking on the listed calibration procedure will display the

required steps to complete the procedure.

Note:

The “Receiver Auto-Set” procedure should be performed in the field. Follow the step-for-step

calibration procedures as required.

This procedure should be

performed in the field

These procedures are factory set

Figure 5-17. PLC Calibration

Power Line Carrier

Table 5-14. PLC Calibration

Description When

Receive Auto-Set Sets up the PLC unit for optimum

performance on a particular PLC channel.

Once the channel has been optimized, this

procedure calibrates the PLC for the

nominal carrier receive level (0 dB),

setting up operation of things like front-

panel CLI meter, Rx alarms, etc.

This procedure is the most commonly run calibration procedure

and is typically the only one that needs to be done in the field. It

should be run:

- Any time there is a change made to the PLC system which

affects the carrier receive level

- At commissioning, after all channel elements (traps, tuners,

hybrids, etc.) have been installed and tuned.

Set TX Monitor Level Calibrates the “TX Power Level”

indication on the Status page and as

reported over DNP.

This is a factory-calibration procedure. This procedure is

typically not done in the field. It is factory-set for 50-ohm

applications

Set Reflected Power Monitor Level Calibrates the “Reflected Power Level”

indication on the Status page and as

reported over DNP.

This is a factory-calibration procedure. This procedure is

typically not done in the field. It is factory-set for 50-ohm

applications.

5.5.3.1 Equipment Requirements

The following equipment is required to perform the commissioning procedure:

Frequency-selective voltmeter (FSVM). Signalcrafters, PowerComm, etc.

Small Flat-head screwdriver (pot tweaker)

50-ohm load or dummy load (minimum 10W rating)

5.5.3.2 Verifying/Adjusting Amplifier Output Impedance

Perform the fine adjustments to precisely match impedance and minimize the reflected power.

The HPS/RFL GARD Pro system PLC amplifier output impedance is factory-set for 50-ohm

impedance.

When the load and source impedance are precisely matched, the loaded output voltage is

exactly one-half of the unloaded output voltage (or, the loaded output is 6dB below the

unloaded output). This fact is used to fine-tune the output impedance of the PLC amplifier.

Proceed with the following steps.

1. Remove the rear PLC board and find jumpers J35/J36. Set the jumpers to “TEST”

and re-insert the module.

2. Send a “Guard” signal (FSK) or “Block” (On/Off) at 1W.

Note:

Set block level to 1W (On/Off), otherwise send 1W Guard (FSK)

3. Disconnect the load from the amplifier.

4. Set the frequency-selective voltmeter (FSVM) to the transmit frequency and

measure the transmit output level across the “PA-OUT” (red and black) test points

on the rear PLC board. Either record the value, or set the meter’s 0 dB reference to

the currently measured value.

5. Re-connect the load, continuing to measure the transmit output level.

6. Adjust the potentiometer R13 on the rear of the amplifier module to achieve 50% of

the previously measured voltage, (or to achieve 6dB below the previously measured

level).

7. Remove the rear PLC board and set jumpers J35/J36 to “NORM”.

Power Line Carrier


5-39

5.5.3.3 Verifying/Adjusting the Transmit Output Power

The PLC amplifier output power level is factory-set for +30dBm (1W) and +40dBm (10W) into

a 50-ohm impedance. This procedure describes how to verify the transmit output power, and

how to make adjustments (if required).

1. Connect the TX port of the PLC to a 50-ohm load.

2. Measure the transmit output level using an FSVM across the “PA-OUT” (red and

black) test points on the power amplifier module.

3. Key the transmitter at 10W using the keying inputs or the input test pages

(See 4.7.1.4)

4. Measure +40dBm (10W at 50-ohm) on the FSVM. If the reading is not +40dBm,

adjust the potentiometer R8 on the rear of the amplifier module to achieve +40dBm

(22.26Vrms).

The procedure is complete. The transmitter levels are now verified / adjusted for 1W and/or

10W.

5.5.3.4 Transmit Fail Adjustment

The PLC amplifier output transmit fail (“TX Fail”) level is factory-set for +28.5dBm into a 50-

ohm impedance. This is typically sufficient for most applications. The TX Fail alarm will go

active if the transmitter output fails below this level. If a different TX Fail level is desired, this

procedure describes how to verify/adjust the TX Fail level.

1. Connect the FSVM to the PA OUT Test Points on the Analog Module and tune the

FSVM for the TX frequency.

2. Send Guard (In FSK) or Block (On/Off) at 1W (30dBm).

3. Adjust R8 on the Power Amplifier until the desired TX Fail Threshold is shown on

the FSVM.

Note:

RFL recommends setting the threshold to 1.5dB below the Guard or Block Signal

level (28.5dBm).

4. Adjust the TX Fail Threshold pot (R19) of the Power Amplifier until the TX Fail

Output turns on.

5. Adjust the Gain pot (R8) on the Power Amplifier until the nominal TX level is

shown on the FSVM.

6. Confirm TX Fail Output is OFF.

5.5.3.5 Hybrid Tuning Procedure (If Equipped)

The PLC internal skewed hybrid is factory-set for a 50-ohm impedance. So long as the

termination impedance is 50-ohm, no adjustment should be necessary. This procedure

describes how to verify the skewed hybrid operation, and how to make adjustments (if

required). The purpose of tuning the PLC internal skewed hybrid is to match the transmit

impedance to the line tuner impedance, in order to minimize reflected power. The skewed

Power Line Carrier


5-40

hybrid also provides isolation between the TX and RX signals, while coupling the transmitter to

the line with minimal loss.

1. Install the amplifier module on a card extender (Part No.500940).

2. Verify that jumpers J12 through J15 do not have jumpers installed.

8. Adjust S1 (coarse) and R46 (fine) for a minimum reading on the FSVM.

9. Insert jumpers J12 through J15 in increasing combinations of capacitance until a

combination is found which achieves a minimum reading on the FSVM.

10. Remove J17 and adjust L4 for fine tuning until a minimum reading on the FSVM is

achieved. If necessary remove jumpers J16 through J20 until a combination is found

which achieves a minimum reading on the FSVM.

11. The adjustment is complete. Remove the amplifier module from the extender card and

install in the chassis.

5.5.4 Setting the Transmit Carrier Frequency Range

The operating band transmit carrier frequency is normally factory set, however if changes are

required in the field the following settings may be followed.

The operating band of the PLC is from 30kHz to 500kHz. Jumpers J3 through J11 on the

Analog Module can be set to accomplish the desired frequency range. Note that the circuit

board has been revised with the addition of jumpers J38, J39 and J40. TABLE 6-4 gives the

assembly numbers for the new Analog Module Assembly with various operating options

followed by the jumper settings to achieve the required frequency range. TABLE 6-3 gives the

assembly numbers for the old board followed by the jumper settings to achieve the required

frequency range.

Note:

On the old board the 393.5kHz to 500kHz version has no jumper settings.

5.5.5 Carrier Level Indicator Settings

The PLC has a carrier level indicator output for use with external measuring devices such as a

panel meter or an analog RTU input. The value at this output represents a variance in received

signal level from the initial signal level when the unit was commissioned. The output is an

analog value that is at mid-scale when the commissioned level is being received. It is above

mid-scale for higher levels and below mid-scale for lower levels.

Power Line Carrier


5-46

The output is a voltage output with one of three jumper selectable resistors in series with it.

When attached to the proper load, the current swings over the designated range.

J32J33J34

Figure 5-23. PLC Analog Module, Carrier Level Indicator Modes - Jumpers

Install a jumper for the required setting as shown below and in the following table. When a

jumper is installed the other two jumpers must be empty (uninstalled).

Note:

The CLI output levels are calibrated during the receiver commissioning procedure and no

further adjustments are necessary or possible.

The three jumper settings are as follows:

The “0-5V” jumper position (J32) puts a 5K ohm resistor in the circuit. When

connected to a high impedance volt meter the resistor is insignificant and the output is

2.5 volts at mid-scale. The scale is 0.25V/dB and the resolution is 1dB. This means

that a signal 6dB higher than commissioned level will result in an output of 4.00 volts.

Similarly, a drop of 6dB will result in an output of 1.00 volts. The maximum scale is

+/- 10dB or 5.00V to 0V.

The “0-1 mA” jumper position (J34) is designed for panel meters with an input load

of 5k Ohms. The full scale output of 5V through 5Kohms will result in 1mA. There is

a 50 ohm resistor in the output circuit to protect against short circuits. The scale will

effectively be 0.05mA/dB.

The “0-100 µA” jumper position (J33) is designed for low impedance current sensors.

Full scale will result in 5V/50Kohms or 100µA. The scale will effectively be 5µA/dB.

The 50W Power Amplifier has a circuit board which contains two programmable jumpers, J6

and J7. In addition to this, the board has five connectors (J1, J2, J3, J4, J5), and five

potentiometers (R8, R14, R69, R74, R83) that must be set for proper system operation. These

components can be seen below. Table 5-6 describes the functions of these components and

indicates how the jumpers and potentiometers must be set.

Two DIP Switch banks SW1 and SW2 have been added to the Power Amp Circuit Board.

These switches are factory set for optimum operation but can be changed in the field if

required. See TABLE 5-21 for a description of the switch functions and their settings.

Two DIP Switch banks SW1 and SW2 have been added to the Power Amp Circuit Board.

These switches are factory set for optimum operation but can be changed in the field if

required. The DIP switches shown above are factory set to protect the circuit board from

overvoltage or excessive phase angle situations. See TABLE 5-22 for a description of the

switch settings.

If the protective circuits are activated the Power Amplifier will shut down for approximately

2.5 seconds and then come up for 25ms. This pattern will continue until the safety parameters

are met and the condition cleared.

The function of the TX Filter is to filter out harmonics and noise that is out of the bandwidth of

the filter. The bandwidth of the filter can be set to either 8kHz or 16kHz using two

programmable jumpers, J1 and J45. The filter center frequency is tunable from 24kHz to

496kHz using programmable jumpers. The outer edges are 20kHz and 500kHz. The 8kHz

bandwidth is used for most applications.

5.6.3.1 Setting Jumpers on the TX Filter

The TX Filter consists of two PC boards that are mounted at right angles to each other and are

supported by an aluminum frame. The TX Filter has a total of 44 jumpers that must be

configured for proper system operation. Two of these jumpers (J1 and J45) are used to select

the bandwidth of the filter which can be either 8kHz or 16kHz. Jumper J44 is used for system

testing, and the other 41 jumpers are used to tune the center frequency of the filter from 24kHz

to 496kHz. The outer edges are 20kHz and 500kHz. Tuning the filter is done from the 9508

TX Filter Programming Sheet supplied by HPS/RFL on the Customer CD. 27 of the jumpers

are located on the 107828-2 board. This is the board with the two large air core inductors

shown on the next page with the location of the jumpers. The remaining 17 Jumpers are located

on the 107828-1 board. The location of these jumpers is shown in FIGURE 5-36. Refer to

Used to select Normal or Test operation. Set to Normal position for normal system operation. Set to Test position to move the T1 Test Point from one coil to another during system testing. Used for tuning the air core inductors L1 and l2.

J1 to J13, and J15 to J43

Used to tune the center frequency of the Tx Filter from 24kHz to 496kHz. The outer edges are 20kHz and 500kHz. Tuning the filter is done from the 9508 Filter Calculation Macro. For example, for a center frequency of 90kHz, the following jumpers should be installed: J3, 5, 6, 8, 10, 11, 18, 20, 23, 24, 34, 35, 37 and 38

5.6.3.2 Transmit Tuning Procedure

1. Use the 9508 TX Filter Programming Sheet (9508 TX Filter Programming Sheet.xls) to

determine jumper settings.

2. Set jumpers as shown.

3. Connect a frequency selective voltmeter to TP1 and TP2 of the Line Board.

4. Apply a sine wave at the center frequency, at a low amplitude (>10VRMS) to the filter

input.

5. Set Jumper J44 in the “Norm” position.

6. Make sure the FSVM has a termination of 50 Ohms or use an external termination in parallel

across TP1-TP2.

7. Make sure the inductor locking screws (on inductor, inside shield) are not fully tightened.

8. Adjust L1 for a minimum level on the meter. If a null is not seen, the lowest value of the

first series capacitance may have to be varied.

9. Set Jumper J44 to the “Test” position.

10. Adjust L2 for a minimum level on the meter. If a null is not seen, the lowest value of the

second series capacitance may have to be varied.

11. Set Jumper J44 back to the “Norm” position.

5.6.5.1.1 Hybrid Transformers

The HPS/RFL 9508 Line Board contains two hybrid transformers, T3 and T4. The primary

winding of T3 accepts the transmit input signal, and the primary winding of T4 develops the

receive output signal that is passed to the RX Filter.

Both hybrid transformers have two secondary windings, and are interconnected so that one

secondary of T3 is in series with a secondary of T4. One set of secondaries is connected across

the complex balance network, and the other set of secondaries is connected to the line coupling

equipment through line matching transformer T2. Fuses F1 and F2 provide overcurrent

protection, and surge arrestors E1 and E2, protect the equipment against an overvoltage

condition. For four wire applications, the signal going to the line coupling equipment can be

monitored at TP2, and the signal coming from the line coupling equipment can be monitored at

TP3. For two wire applications the signal going to or coming from the line coupling equipment

can be monitored at TP2.

5.6.5.1.2 Receive Attenuator

Resistors R9, R11, R12 and dual-section Receive Level potentiometer R10 are connected across

the primary of T4 to form an attenuator. The amount of signal sent to the RX Filter is

controlled by the setting of R10. Zener diodes CR1 and CR2 clamp the signal to a safe level.

The signal being sent to the RX Filter can be monitored at test points TP6 and TP7.

5.6.5.1.3 Complex Balance Network

Inductors L1 through L8, capacitors C1 through C9, Coarse Switch S1, fine potentiometer R1

and resistors R2 through R8 form an internal reactive balance network. This network is

connected across one set of secondaries of the hybrid transformers. Jumper J13 can be used to

enable or disable the internal balance network. The balance network is adjusted to match the

line impedance. To adjust the network, a frequency selective voltmeter (FSVM) is connected

across test points TP6 and TP7 on the Line Board, and S1 and R1 are adjusted to the lowest

possible transmitter signal level. S1 provides a rough adjustment of the resistance across the

hybrid secondaries by determining how many resistors in the network are connected in series.

R1 provides a fine resistance adjustment that allows the resistive balance to be precisely set.

Inductors L1 through L8 and capacitors C1 through C9 form the reactive portion of the balance

network. All components in the reactive portion can be jumpered in or out to balance out local

line reactance. L1 through L8 can be enabled or disabled by jumpers J13 through J19. Jumper

J1 controls C1, J2 controls C2, and so on. If no reactive balancing is required, J1 through J9,

and J14 through J19 must be placed in the out position.

5.6.5.1.4 Dummy Load

An internal Dummy Load and Attenuator Board are provided as described in Section 5.6.8. A

dummy load is a non-inductive load, typically 50ohms used when testing a PLC transmitter.

Use test points TP1 and TP2 to observe the signal going to the line coupling equipment.

5.6.5.1.5 Impedance Matching Transformers

Impedance matching transformers T1 and T2 match the impedance of the Line Board to that of

the line. Jumper J10 selects one of T1’s four impedance settings: 50, 75, 100, or 130 ohms.

Fuse F1 provides current protection, and surge arrestor E2 protects the equipment against an

overvoltage condition. Jumper J20 selects one of T2’s four impedance settings: 50, 75, 100, or

Power Line Carrier


5-67

130 ohms. Fuse F2 provides current protection, and surge arrestor E1 protects the equipment

against an overvoltage condition. In 2 wire applications, the signal going to or coming from the

line coupling equipment can be monitored at test point TP2. In 4 wire applications, the signal

going to the line coupling equipment can be monitored at test point TP2, and the signal coming

from the line coupling equipment can be monitored at test point TP3.

5.6.5.2 Setting Jumpers and Controls on the Line Board

The Line Board has 25 jumpers that must be set for proper system operation. Two of these

jumpers, J10 and J20, are for impedance matching, 12 jumpers are used for balancing the line

impedance, and 4 jumpers are used to select 2W or 4W operation. The location of these

jumpers is shown below. Refer to TABLE 5-26 for information on how to configure these

jumpers on the Line Board.

The function of the Rx Filter is to prevent harmonics and noise from coming into the 8790 Pro

from the power line that is out of the bandwidth of the filter. The bandwidth of the Rx Filter

can be set to either 8kHz or 16kHz using two programmable jumpers on the board. The filter

center frequency is tunable from 24kHz to 496kHz using programmable jumpers. The outer

edges are 20kHz and 500kHz. The 8kHz bandwidth is used for most applications. The Rx

Filter Board is optional and is typically replaced with the Rx Connection Board.

TB1-7 (Chassis ground) is an alternate method. This will cause surge currents to pass through

the Mother Board and chassis before exiting to ground. Connecting directly to the sub-station

ground bar is preferred.

5.6.10 Quick Tuning Procedure and Jumper Setting Overview

1. For the selected center frequency, set the jumpers as described in the Microsoft Excel®

Worksheet “9508 Rx Filter Programming Sheet.xls.”

5.7 Optional Switched Battery Power Supply

I/O Module, Single On/Off Switch

This module was developed for use when a PLC (On/Off) module is installed in a HPS/RFL

GARD Pro system chassis. Input power is feed out to an auxiliary device through the Switched

Battery Terminals as shown below. No communication interface is possible with this Power

Supply I/O when a double pole switch is used.

Troubleshooting Section 6.

6.1 Introduction

1. This section describes troubleshooting procedures that can be done by the user in the

field. Please contact HPS/RFL Service at 973.334.3100 or by e-mail at

[email protected] for further assistance.

Troubleshooting can be broken down into the following two types:

1. Setup Errors.

2. Equipment Problems.

The basic objective of any troubleshooting guide is to determine the type and location of a

problem. Once this is accomplished, taking one of the following actions will usually restore the

HPS/RFL™ GARD Pro™ system to operation.

1. For setup problems, verify and re-configure the unit or units that were not setup

correctly.

2. For equipment problems, contact HPS/RFL by phone at 973.334.3100 or by e-mail at

[email protected]

6.2 Connectivity Issues

Once a PC is physically connected to a GARD unit through the front Ethernet port and there is

no access to the device the following steps will assist in restoring access.

1. Ensure that the power light is illuminated on the HPS/RFL GARD Pro system.

2. Check the LAN settings on your computer.

a) Go to the command prompt and type “ipconfig”

b) Then visually confirm the IP information is correct.

c) See Section 4.1

3. Check the Ethernet cable with a connectivity tester to verify functionality.

4. Use the flow chart on the following page to further identify connectivity issues.

6.3 Module Level Alarms

Each module can report a Major or Minor alarm. This information is sent over the Control Bus

and is a status condition only. The time critical alarms should be handled by the logic

functions. Not all modules generate alarms.

The criteria for a module going into Major or Minor alarm is hard-wired into the module and

cannot be changed by the user. However, how the system reacts to these alarms is controlled

by the user. For each alarm type on each module, the user can select if he wants to put the

system into Major Alarm, Minor Alarm, or to ignore the module alarm.

The user programs the HPS/RFL GARD Pro system alarms using the Alarm Configurations

Software Upgrade Utility Section 7.

7.1 System Firmware Upgrade Overview

The HPS/RFL™ GARD Pro™ system uses an upgrade tool to install a new system firmware.

RFL now provides the ability to have a backup image of the system firmware. The new

firmware will swap the configuration into a standby partition. This greatly lessens the

downtime when upgrading takes place. This also provides the ability to revert back to the

previous firmware.

Advanced Settings Select “Show Advance Settings” to select the following advanced options. Also select

“Advanced Settings” to choose a different IP address.

Advanced Setting Functionality

Upload – Upload new firmware as standby (selected by default)

Swap & Reboot – Make standby version active (selected by default)

Configuration

o Use Current – Use current configuration after swap and reboot (selected by default)

Note:

The Use Current option is only valid when uploading firmware of equal or greater database

versions. The database version is indicated by the second digit in the firmware release number.

Example: GPRO.2.1.0.7432, where the second digit is 1. If the database version is less than

the current firmware this option is not valid and current configuration will not be present after

reboot.

o Use Standby – Use configuration in the standby partition after swap and reboot

o Reset to Default – Reset configuration values to default after swap and reboot

Power Line Carrier


7-2

Note the following:

Always check the Swap and Reboot when performing a firmware upgrade.

If the Upgrade option is checked without the Swap & Reboot checked, only the Standby

version will be updated.

If the reboot box is checked the Interface Unit will automatically reboot at the end of the

upgrade.
