2 System overview

2.1 General descrip t ion

InteliCompactNT

(also IC-NT) Family controllers are comprehensive gen-set controllers for single andmultiple generating sets operating in stand-by or parallel modes. A modular construction allowsupgrades to different levels of complexity in order to provide the best solution for various customerapplications. The controllers are equipped with a powerful graphic display showing icons, symbols andbar graphs for intuitive operation, which, together with its high level of functionality, sets newstandards in Gen-set controls.

The key features are:

Easy-to-use operation and installation. The factory default configuration covers mostapplications

Various customizations are possible thanks to its configurability

Excellent remote communication capabilities

High level of support for EFI engines (most world producers)

High reliability

2.2 Conf igurabi l ity and monitor ing

One of the key features of the controller is the system’s high level of adaptability to the needs of eachindividual application and wide possibilities for monitoring. This can be achieved by configuring andusing the powerful ComAp PC/mobile tools.

Supported configuration and monitoring tools:

- LiteEdit – complete configuration and single gen-set monitoring- InteliMonitor – multiple site monitoring and setpoint setting- WinScope – special graphical monitoring software- WebSupervisor – web-based system for monitoring and controlling

o WebSupervisor mobile – supporting application for smartphones

NOTE: Use the LiteEdit PC software to read, view and modify configuration from the controller or disk andwrite the new configuration to the controller or disk.

The firmware of InteliCompactNT

contains a large number of binary inputs and outputs needed for allnecessary functions available. However, not all functions are required at the same time on the samegen-set and also the controller hardware does not have so many input and output terminals. One ofthe main tasks of the configuration is mapping of “logical” firmware inputs and outputs to the “physical” hardware inputs and outputs.

Configuration parts:

1. Mapping of logical binary inputs (functions) or assigning alarms to physical binary inputterminals

2. Mapping of logical binary outputs (functions) to physical binary output terminals3. Assigning sensor characteristics and alarms to analog inputs4. Assigning control values and output characteristics to analog outputs5. Selection of peripheral modules which are connected to the controller and doing the same as

the above for them

6. Selection of ECU type if an ECU is connected7. Changing the language of the controller interface

PRINCIPLE OF BINARY INPUTS AND OUTPUTS CONFIGURATION

The controller is shipped with a default configuration, which should be suitable for most standardapplications. This default configuration can be changed only by using a PC with the LiteEdit software.See LiteEdit documentation for details.

NOTE: You need one of communication modules to connect the controller to a PC with LiteEdit. There is aspecial easy removable service module for cases when no communication module is permanentlyattached.

Once the configuration is modified, it can be saved to a file for later usage with another controller or forbackup purposes. The file is called archive and has the file extension .aic. An archive contains a fullimage of the controller at the time of saving (if the controller is online for the PC) except the firmware.Besides configuration it also contains current adjustment of all setpoints, all measured values, a copyof the history log and a copy of the alarm list.

The archive can be simply used for cloning controllers, i.e. preparing controllers with identicalconfiguration and settings.

ISLAND-PARALLEL OPERATION WITH AMF AND WITHOUT PARALLELING

2.4 True RMS measurement

This controller measures AC values based on the True RMS principle. This principle corresponds

exactly to the physical definition of alternating voltage and current effective values. Under normalcircumstances the mains voltage and current should have a pure sinusoidal waveform. However,some nonlinear elements connected to the mains produce harmonic waveforms with frequencies ofmultiples of the basic mains frequency and this may result in deformation of the voltage and/or currentwaveforms. The True RMS measurement gives accurate readings of effective values not only forpure sinusoidal waveforms, but also for deformed waveforms.

NOTE: The harmonic deformation causes that the Power Factor of a generator working parallel with themains cannot reach values in a certain range around the PF 1.00. The higher the deformation, thewider the power factor dead range. If the requested power factor is adjusted inside the dead range,the controller cannot reach the requested value because of this fact.

3.5 General

To ensure proper function:

Use grounding terminals.

Wiring for binary inputs and analog inputs must not be run with power cables.

Analog and binary inputs should use shielded cables, especially when the length is more than3 m.

3.6 Wiring

Tightening torque, allowed wire size and type, for the Field-Wiring Terminals:

Based on terminal type:1. PA256:

SPECIFIED TIGHTENING TORQUE 0.5 NM (4.4 IN-LB)

2. 2EDGK:

SPECIFIED TIGHTENING TORQUE 0.4 NM (3.5 IN-LB)

For field type terminals:Use only diameter 2.0 –0.5 mm (12 –26 AWG) conductor, rated for 75 °C minimum.

For Mains (Bus) Voltage and Generator Voltage terminalsUse only diameter 2.0-0.5 mm (12 –26 AWG) conductor, rated for 90 °C minimum.

Use copper conductors only.

3.7 Grounding

The shortest possible piece of wire should be used for controller grounding. Use cable min. 2.5 mm2.

A brass M4x10 screw with star washer securing ring type grounding terminal shall be used.

The negative “-” battery terminal must be properly grounded.

Switchboard and engine must be grounded at a common point. Use as short a cable aspossible to the grounding point.

3.8 Power sup ply

To ensure proper function:

Use min. power supply cable of 1.5 mm2

The maximum continuous DC power supply voltage is 36 V DC. The maximum allowable powersupply voltage is 39 V DC. The InteliCompact’s power supply terminals are protected against largepulse power disturbances. When there is a potential risk of the controller being subjected toconditions outside its capabilities, an outside protection device should be used.

It is necessary to ensure that potential difference between the generator current COM terminaland the battery “-” terminal is maximum ± 2 V. Therefore, it is strongly recommended tointerconnect these two terminals together.

H INT :

The InteliCompactNT

controller should be grounded properly in order to protect against lighting strikes!!

The maximum allowable current through the controller’s negative terminal is 4A (this is dependent onbinary output load).

InteliCompactNT


For connection with a 12 V DC power supply, the InteliCompactNT

includes internal capacitors thatallow the controller to continue operation during cranking if the battery voltage dip occurs. If the batteryvoltage is 10 V before the dip and it recovers to 7 V within 100 ms the controller continues operating.During this voltage dip, the controller screen backlight may turn on and off but the controller keepsoperating.

It is possible to further support the controller by connecting the external capacitor and separating

diode or I-LBA module:

The capacitor size depends on the required time. It shall be approximately in the thousands ofmicrofarads.

The capacitor size should be 5000 microfarad to withstand a 150 ms voltage dip under the followingconditions:

Voltage before dip is 12 V, after 150 ms the voltage recovers to the min. allowed voltage, i.e. 8 V.

The I-LBA module ensures a min. 350 ms voltage dip under following conditions:

Communication and extension plug-in modules are connected.

Voltage before dip is 12 V and after 350 ms the voltage recovers to the min. allowed voltage5 V.

The I-LBA enables controller operation from 5 V DC (for 10 to 30 seconds).

The wiring resistance from the battery should be up to 0.1 Ω for proper function of the I-LBA.

H INT :

I-LBA may not eliminate voltage drop when used with the low temperature (-40 °C) version of the

controller and the display heating element is on (below 5 °C). The current drain of the heating elementexhausts LBA capacitors very fast.

3.8.1 Power supply fusing

A one-amp fuse should be connected in line with the battery positive terminal to the controller andmodules. These items should never be connected directly to the starting battery.

Fuse value and type depends on the number of connected devices and wire length.

The recommended fuse type (not fast) is T1A due to internal capacitors charging duringpower up.

NOTE: IT IS NECESSARY TO ENSURE THAT THE POTENTIAL DIFFERENCE BETWEEN THE GENERATOR CURRENT COM TERMINAL AND THE BATTERY “-” TERMINAL IS MAXIMUM ± 2V. THEREFORE, IT IS STRONGLY RECOMMENDED TOINTERCONNECT THESE TWO TERMINALS TOGETHER.

CAUTION:

WHEN YOU ARE USING INTELICOMPACTNT HW VERSION 1.3 OR NEWER IT IS NECESSARY TO UPGRADE THEFIRMWARE TO IC-NT-1.4.3 OR NEWER .

Since HW version 1.3 the InteliCompactNT

measures current with reversed polarity. It is notrecommended to switch wiring at the current transformer side. To fix this error use FW IC-NT-1.4.3 ornewer.

3.10 Speed measurement

The engine speed can be measured either from the generator frequency or from a magnetic pickup. If

an EFI engine is configured, the engine speed is obtained from the ECU.

3.10.1 Pickup

A magnetic speed sensor (pickup) is the most common method of engine speed measurement. Touse this method, mount the pickup opposite to the engine flywheel, connect the cable to the controlleras shown on the picture below and adjust the setpoint Gear Teeth according to the number of teeth onthe flywheel.

See the chapter Technical data for details about the pickup input parameters.

3.10.3 Additional running engine indication

It is helpful to have information other than speed (RPM), whether the engine is rotating or not,especially if RPM is measured from the generator frequency instead of magnetic pickup. Thegenerator frequency measurement can be unreliable at very low speeds and/or may have a delayedreaction to sudden and big changes (i.e. in the moment that the engine has just started…).

The following conditions are evaluated as additional running engine indication:

Voltage on the D+ input is higher than 80% of battery voltage. Connect this input to the D+ (L)terminal of the charging alternator and enable the D+ function by the setpoint D+ Function. IfD+ terminal is not available, leave the input unconnected and disable the function.

The pickup is not used and frequency is detected on the pickup input. Connect the pickupinput to the W terminal of the charging alternator if you do not use pickup and the W terminalis available. If not, leave the input unconnected.

NOTE: The starter cut-off frequency has to be adjusted by the setpoint Start W Freq. If you know the chargingalternator nominal frequency, adjust the setpoint to the frequency obtained from following equation:

cutoff = nom ∙ (" "" ") If you do not know the charging alternator nominal frequency, follow this procedure:

1) Make sure that the starting accumulator is fully charged.

2) Close a fuel valve manually to disable the engine from being started.


23/288

InteliCompactNT


3) Connect a PC with LiteEdit to the controller and display "Values" window, group "Engine", valueW-TerminalFreq.

4) Select MAN mode and press the Start button to crank the gen-set. Make a note about the Wterminal frequency while the gen-set is cranking.

5) Press the Stop button to stop cranking.6) Adjust the setpoint Start W Freq to a value twice that which you measured during cranking.

Oil pressure > Starting Oil P setpoint. The oil pressure is evaluated from the analog input 1 orfrom the ECU if an ECU is configured.

At least one phase of generator voltage is >20% of nominal voltage.

These signals are used during start for powering down the starter motor even if still no RPM ismeasured and also during stop in order to evaluate if the engine is really stopped.

WIRING OF BINARY OUTPUTS

NOTE: Outputs can provide steady current of up to 2A. Every single binary output can provide up to 0.5A ofsteady current unless the total current of all binary outputs does not exceed 2A.

3.13 Analog inpu ts

The analog inputs are designed for resistive automotive type sensors like VDO or DATCON. Thesensors are connected either by one wire (the second pole is the sensor body) or by two wires.

In the case of grounded sensors, connect the AI COM terminal to the engine body as near to

the sensors as possible. In the case of isolated sensors, connect the AI COM terminal to the negative power supply

terminal of the controller as well as the opposite poles of the sensors.

NOTE: The fail sensor alarm is issued if the measured resistance is smaller than one half of the first (lowest)point of the sensor curve characteristic or is greater than 112.5% of the last (highest) point of thesensor curve characteristic.NOTE: Analog inputs are typically used for: Oil Pressure, Water Temperature and Fuel Level. All of theseparameters are connected with relevant protections.

Protection of Oil Pressure and the relevant condition of a running engine is joined with AI01 only if:

- the ECU is not configured- the ECU is configured and the AI01 is set to Alarm + ECU.

3.14 Circu it breakers

There are two power switches controlled by the controller:

The generator circuit breaker or contactor – GCB

The Mains circuit breaker or contactor – MCB (SPtM application only)

It is possible to use either a motorized circuit breaker or contactor. Below is a list of available controloutputs that should fit all types of contactors or breakers. The following rules must be kept to whendesigning the wiring of power switches:

The control outputs must be configured and wiring of the power switches must be provided insuch a way, that the controller has full control over the breakers – i.e. the controller can openand close the breaker at any time.

The breaker must respond within max. 2 seconds to a close and open command. Specialattention should be paid to opening of motorized circuit breakers, as it could take more than 2seconds on some types. In such cases it is necessary to use an undervoltage coil for fastopening.

The breaker feedback functions must be configured onto some binary inputs and the signalsfrom the breakers must be connected to it and provide reliable information about the breakerposition.

3.14.1 Breaker control outputs

Close/open An output for control of a contactor. Its state represents the breaker positionrequested by the controller. The breaker must react within 2 seconds to a close oropen command, otherwise an alarm is issued.

ON coil An output giving a 2 second pulse in the moment the breaker has to be closed. The

output is intended for control of close coils of circuit breakers.

OFF coil An output giving a pulse in the moment the breaker has to be opened. The pulselasts until the feedback deactivates, but at least for 2 seconds. The output isintended for control of open coils of circuit breakers.

UV coil

The output is active the whole time the gen-set is running (GCB, not in idle orcooling) or the controller is switched on (MCB). The output is deactivated for at least2 seconds in the moment the breaker has to be switched off. The output is intendedfor control of undervoltage coils of circuit breakers.

3.14.2 MCB special requirementsSPtM only

1. If a contactor is used on the MCB position, it is recommended that the wiring be provided insuch a way that the contactor will be normally closed and will open if the MCB Close/Open closes. This behaviour is called “negative logic” and can be adjusted by the setpoint MCB

Logic . The negative logic will prevent accidental opening of the MCB when the controller isswitched off.2. If a contactor is used on the MCB position, it will open itself immediately after the mains have

failed, because it will lose power for the coil. That is why the following adjustment is necessaryto prevent triggering the MCB fail alarm: MCB Opens On = MAINSFAIL, Mains V Del ≤ 1.

3. If a 230 V motor driven circuit breaker is used on the MCB position and an undervoltage coil isnot fitted, it is not possible to open the breaker after the mains have failed, because there is nopower for the motor drive until the gen-set is started and providing voltage. Adjusting thesetpoint MCB Opens On = GEN RUN will prevent triggering the MCB fail alarm.

3.15 AVR interface

The AVR output is used to control the voltage or power factor of the generator via the remote voltageadjust input provided by the AVR.

The output from the controller is a 5V PWM that is designed to be used together with the IG-AVRi module. The AVRi module provides galvanic separation of the controller from the generator and PWMto voltage conversion, which is needed for most AVRs. The output from the IG-AVRi module isavailable as positive, negative or symmetric. The output voltage range is adjustable by a trimmerlocated on the module.

The initial level of the AVR output is adjustable by the setpoint AVRi Bias.

3.15.1 IG-AVRi

Automatic voltage Regulator interface is used for volt/PF control adjustment through galvanicseparated inputs and outputs.

CAUTION:Refer each time to the corresponding AVR manual before connecting the interface. IG-AVRi-TRANS(AC power supply for AVRi) has to be supplied from gen-set voltage.

AVRi output can be connected as symmetrical: OUT1-OUT2 or unsymmetrical OUT1-GND or OUT2-GND.

- The potentiometer on the AVRi defines maximum OUT1, OUT2 voltage range.- Use symmetrical (OUT1, OUT2) AVRi output to connect the AVRi to AVR auxiliary voltage

input.- Use unsymmetrical output if an external AVR potentiometer has to be replaced with AVRi.- AVRi output voltage should change the generator voltage typically in the range ± 10% of the

Nominal voltage.

NOTE:IG-AVRi is not included in the standard package with the controller.IG-AVRi TRANS/LV is a power supply unit for IG-AVRi; it is not included with the IG-AVRi package.
