3 Connection

The following standards and regulations are applicable to the unit:

EN 60950 EN 55022

EN 61000-3-2 EN 61000-3-3 EN 61000-4-2

EN 61000-4-3 EN 61000-4-4 EN 61000-4-5

In the standard version, the device and the insulating transformer correspond to

protection class I. The transformer corresponds to the regulation EN 61558 and

the test voltage primary/secondary is 4 kV alternating voltage.

The unit as delivered is ready for operation.

Installation and trouble-free operation are only guaranteed in the special

equipment rack.

This device (protection type: IP 20) must be installed in a dry and dust-

protected environment. The cooling air must not be obstructed.

Pay attention to the block circuit diagram. The supply circuit must be fitted with an isolating device which

must be easily accessible if permanently connected;

must be easily accessible and provided close to the device if it is a plug connection.

Provide appropriate fuses for mains and output cables (size of fuse,

characteristic, see technical data).

Access to the input and output fuses is only possible after opening the unit.

Before connecting up, compare the information on the rating plate and data

sheet with the actual input and output voltages.

The details on the rating plate and in the data sheet with regard to power

consumption apply to rated conditions of input voltage and the Normal operating mode. The value in brackets is the maximum input current with

maximum input voltage tolerance.

Connect only when the voltage is switched off.

The unit must be connected to the neutral conductor of the supply power circuit

according to local regulations.



10.11.10 BGOE/COBS 10/73 4640 en

Because of the high energy of the battery to be connected, special safety

precautions must be taken.

To protect the unit from overvoltages (e.g. due to lightning strikes), carry out

potential equalisation using an adequate cable cross section (e.g. 6

mm2/AWG10) on the rack if no other measures to protect the unit are provided,

e.g. building protection.



10.11.10 BGOE/COBS 11/73 4640 en

4 General

The power modules described below (also referred to as unit or Dc-DC

converter) are designed using pulse technology.

This technology results in a good efficiency and good dynamic control

characteristics in the event of input voltage changes and load steps.

As these power modules have a very compact design and can be connected in

parallel, powerful supply systems can be built up in conjunction with

equipment racks.

The primary switched DC-DC converters of the TEBECHOP series were

developed to generate output voltages of 24V DC, 48V DC, 60V DC, 110V

DC or 220V DC from a central 110V DC or 220V DC supply.

They are mainly used for the decentralised 24V DC supply in energy supply

companies or for supplying telecommunication systems with 48V DC and/or

60V DC.

By connecting several devices in parallel, the required load power can be

adjusted individually.

The main components of these modular power supply systems are the power

modules (output voltages: 24V, 48V, 60V, 110V or 220V) with racks (19" 5-

way without MCU 2500 HDI remote monitoring system and 19" 4-way with

integral MCU 2500 HDI remote monitoring system).

The power modules are connected in parallel within the rack. The output power

can also be flexibly scaled (even retrospectively) and several racks can be

connected in parallel. This enables redundant power supplies (e.g. n+1

redundancy) to be implemented in a compact unit.

Only 3 height units are required for installation in appropriate system cabinets.

Racks with integral MCU 2500 HDI remote monitoring system enable 4

power modules to be fitted.

Further racks can easily be connected in parallel by connecting the +/- outputs

of the parallel-running connector and the SAT-Bus.

Up to 24 units: direct addressing

Further units: SAT-Bus connection via bus converter (Part No. 525886, see

description: 4553), see also Chapter 15 of these operating instructions. The

maximum number of controllable DC-DC converters is limited to 99 units by

the MCU 2500 HDI remote monitoring system.

The DC-DC converters have an IU-characteristic



10.11.10 BGOE/COBS 12/73 4640 en

The output voltage is kept constant with an accuracy of 1 %. On reaching the

current limit, control changes electronically from voltage to current control.

When the output of the DC-DC converter is overloaded or a short circuit

occurs, the 2-way rated current can be supplied for 2 seconds. During this time,

the short-circuit should be isolated through activating a fuse. The consequence

of current limitation if applicable is a drop of the output voltage in the event of

a short circuit to < 1 V.

If after this time the output current does not drop to 100%, after approx. 5

seconds the output voltage is switched off.

Note: The rating of the fuse must be observed.

This measure makes the device continuously short-circuit proof.

Fluctuations of input voltage (see technical data sheet) and load changes have

no effect on the quality of the voltage and current constancy and are regulated.

The DC-DC converter is equipped with a so-called satellite. This assembly

integrated in the DC-DC converter enables a remote monitoring system to be

set up using the MCU 2500 HDI remote operating system.

Faults can be transmitted by means of voltage-free contacts using the MCU

2500 HDI remote monitoring system.

Note: Always operate DC-DC converters with a standalone MCU, i.e. do

not establish a SAT connection with other systems, e.g. rectifiers or

inverters.

For further information on the task of the satellite, see chapter 16.



10.11.10 BGOE/COBS 13/73 4640 en

5 Principle of operation

The voltage fed in through the input filter is supplied to a step-up converter

through the DC-DC converter. A special control method provides a constant

DC voltage for the main converter at the output of the step-up converter.

Rapid MOSFET power transistors in the main converter convert the DC

voltage into a rectangular voltage. Control is effected by changing the switch-

on time at constant frequency. The power transmitter provides potential

isolation and transforms the rectangular voltage to the desired output value.

Diodes rectify the voltage and an LC filter is used to smooth the output voltage.

The unit is equipped with a hardware overvoltage cut-out.

DC-DC converters with an output voltage of 24-60V are additionally equipped

with a surge disconnect threshold that is configurable by the software.

After a fault has been repaired, the unit can be restarted when it has been

isolated from the mains for about 10 seconds or if it has been reset via the

MCU 2500 HDI remote monitoring system.

10 MCU 2500 HDI remote monitoring system

10.1 General

The MCU 2500 HDI remote monitoring system is a microprocessor-

controlled monitoring and control unit. With this system, it is possible to

monitor and control all the main components of a power supply system.

There are two options for this system:

- Equipment rack incl. MCU 2500 HDI remote monitoring system

- Alternatively, equipment rack with power modules and MCU 2500 HDI

remote monitoring system as a component for fitting in the system cabinet

The connection to the outside world is made via the serial interface on the front

panel (X110, RS 232, 9-pin SUB-D). The MCU 2500 HDI remote

monitoring system can be directly connected to a personal computer (PC).

The installed service software (see description: 3293) allows comprehensive

monitoring and controlling of the power supply system. If the control desk is

not local, the connection to the computer can be created using a modem and the

public telephone network or by means of a TCP/IP adapter and the internet.

The MCU 2500 HDI remote monitoring system therefore allows more

rational and efficient employment of maintenance and service personnel.

When developing the components for this new range, the highest priority was

placed on flexible, user-independent implementation and on a significant

reduction in volume of each individual system component.

Components for external connection and their function, see Description 4339

(MCU 2500 HDI remote monitoring system).

Note: Always operate DC-DC converters with a standalone MCU, i.e. do not

establish a SAT connection with other systems, e.g. rectifiers or inverters.

10.2 MCU 2500 HDI remote monitoring system:

This unit is the heart of the MCU 2500 HDI remote monitoring system (see

Figure 2). All other components are connected to this unit. MCU main board,

LC display and RS232 interface (see front view) are incorporated.

Included as standard in the design Equipment rack incl. MCU 2500 HDI.

10.3 Bus systems / interfaces

The data of the individual components are exchanged via different bus systems,

depending on the type and task of the respective component.



10.11.10 BGOE/COBS 25/73 4640 en

BENNING Net (ADBUS) (X102) Remote peripheral components are connected to the base unit via the

BENNING Net (ADBUS). These are units with signalling relay and digital

inputs, measuring boards with analogue inputs, battery symmetry monitoring

units or earth fault monitoring units. All these components must be installed in

the immediate vicinity of the base unit (i.e. in the same cabinet).

Cabling using commercially available network cable (patch cable).

Caution!

No more than 7 users may be connected to the BENNING Net

(ADBUS).

SAT-Bus X9, X10 The power supply system DC-DC converters, for example, are connected to the

MCU 2500 HDI remote monitoring system via the SAT-Bus.

Communication with other equipment racks also takes place via this SAT-Bus.

The components can be distributed over several cabinets.

RS232 interface (SUB-D 9-pin), X110 Communication with the outside world takes place via this interface on the

front panel. A PC with the appropriate service software is connected either

directly to this interface or via the telephone network (modem) or the internet /

network (TCP/IP adapter).

Caution! The BENNING Net (ADBUS) and the SAT-Bus use the same plug

on the base unit. Once the first SAT-bus component has been

connected, it will no longer be possible to connect a further

BENNING Net (ADBUS) component, as the power supply for

these components will be interrupted. Cabling using commercially

available network cable (patch cable).

10.4 Components of the MCU 2500 HDI remote monitoring system

The MCU 2500 HDI remote monitoring system consists of different

hardware and software components. Some components are essential, others are

optional. All components are described in Description 4339 to enable the

system to be installed and commissioned safely.

Figure 11: Basic structure of the remote monitoring system



10.11.10 BGOE/COBS 27/73 4640 en

Key:

1 Measuring board TUII (ADBUS component)

2 Relay box (SAT-bus component)

3 Battery symmetry monitoring (ADBUS component)

4 Digital input box (SAT-Bus component)

5 RELIO board (ADBUS component)

6 Measuring box (SAT-Bus component)

7 Power supply system with suitable components for connection to the

SAT-Bus (DC-DC converter, inverter, .... )

10.5 ADBUS components

ADBUS components can be regarded as hardware expansions. They are

mounted directly in the cabinet on a DIN rail close to the measuring and

monitoring locations. This reduces the extent of cabling work.

The components can be connected to each other and to the base unit with

commercially available network cables (patch cables). The network cable also

supplies power to the components. Usually, blue cables are used to distinguish

them from the SAT-Bus wiring.

The address assignment and/or the necessary configuration are carried out

using only two jumpers. This enables a service engineer to replace components

on site without taking further measures.

Caution! Some special features must be observed due to the technical

specification of the ADBUS:

No more than 7 components may be connected

The maximum length of the complete ADBUS must not exceed 3m

An ADBUS component cannot be connected downstream of a SAT-Bus component, as this would interrupt the supply



10.11.10 BGOE/COBS 28/73 4640 en

10.6 SAT-Bus components

The SAT-Bus components include measured value recording and signalling

components (relay box, measuring box, digital input box). They can be

mounted directly in the cabinet on a DIN rail close to the measuring and

monitoring locations. The necessary mounting rail adapter is pre-fitted in the

factory. Fitting on a mounting plate is also possible. The fixing dimensions

required can be found in the dimension diagram.

The components are connected to one another using SAT-Bus cables or

commercially available network cables (patch cable).

The components are configured via an internal programming system which has

already been implemented in the factory.

10.7 RS232 components

The RS232 components are used for external communication. These are

components which have not been developed specially for use in a remote

monitoring system. These components are always connected via the 9-pin D-

SUB plug X110 (front panel) on the base unit.

External modem

The remote monitoring system can be connected to the public telephone

network via an analogue modem. A high-speed modem has been tested and

approved especially for industrial use.

(PSTN modem V.90-highspeed; MicroLink 56k; Part No. 787663)

MCU-TCP/IP adapter

The remote monitoring system can be connected to a computer network or the

internet via an appropriate MCU-TCP/IP adapter. (Part No. 520421)

Service PC

The TEBE MCU Service software (Part No. 545740) installed on the service

PC can be used for detailed monitoring of the power supply system and

changing the system parameters. There are no special hardware requirements.

A WINDOWS operating system (from WINDOWS 9x) is all that is required.

10.8 Graphical display

On the 4 buttons of the graphic display on the front panel, all the release

statuses and measured values of the power supply system can be displayed or

set. Critical menu levels are accessible by means of a password only. The

operation and function of the input buttons and the meaning of the statuses and

values indicated will be explained later in more detail.

11 Installation and commissioning

After installation, connection and commissioning of the MCU 2500 HDI

remote monitoring system, all the components are fully ready for operation.

Caution!

The safety instructions must be observed at all times during

installation, connection and commissioning.

All components are designed for use in closed dry rooms. The maximum

permissible ambient temperature is 40C. Attention must be paid that the

components are not exposed to aggressive substances and the passage of

cooling air is not hampered.

The entire power supply system with all the components belonging to the MCU

must be wired and connected to the power supply system to enable

commissioning to be carried out. When the initialisation phase is complete, the

display shows a measured value of the system.

11.1 Using the graphical display

Each menu item can be accessed and settings can be made using the four

function keys below the display. However, some menu items are protected by a

password. The system automatically returns to the initial state from any menu

item when no button has been actuated for about 1 minute.

appears.

Press the keys to change between the 3 specified measured

values. Press the key to return to the main menu.

The symbol indicates that a new log file entry is present, which has

not yet been viewed and acknowledged. Press the key to jump directly to the

log file entry.

11.3 Passwords

Different menus are accessible by means of a password only.

The password 1 is set to 001 in the factory, and password 2 is set to 002.

Caution! For safety reasons, it is important to change this password after

commissioning the system.

11.4 Menu structure

The menu structure and the individual menu levels and menu items are the

same for all applications. Only the assignment and meaning of the digital

inputs, the measured values and the type of SAT-Bus users depend on the

individual user.

25 Parallel operation

Parallel operation of several equipment racks is also possible without

decoupling diodes at the rack output.

Note:

DC-DC converters with output voltage 110/220V have integral decoupling

diodes.

In order to distribute the output current symmetrically, connect the equipment

racks together by means of contact X17:1 or 2 (parallel-running connector). The SAT-Bus connection (X9 or X10) must also be inserted for parallel

operation with several equipment racks to enable data to be exchanged between

the racks (BENNING SAT cable or patch cable with Western plug 8-pin RJ45). An active parallel-running circuit enables a parallel-running tolerance of

approximately. 5 % of Irated to be achieved on load from 30 - 100%.

When an additional unit is connected, the voltage and therefore current

balancing can take up to 5 minutes (10 mV control steps).

For safe holding of the fault contact, a minimum basic load of >

5 % is required with parallel operation.

The SAT-Bus cable must be connected when operating several

equipment racks in parallel to enable data to be exchanged

between the racks. In addition to this, the parallel-running connection of the racks must also be connected together.

Note: Parallel connection, up to 24 units: direct addressing

Further units, SAT-Bus connection only via bus converter

(Part No. 525886, see Description: 4553)

The TEBECHOP bus converter is provided for simultaneously operating more

than 24 DC-DC converters in parallel with one MCU in conjunction with the

MCU 2500 HDI remote monitoring system. The maximum number of

controllable DC-DC converters is limited to 99 units by the MCU 2500.

The bus converter automatically configures all DC-DC converters associated

with the group. It is not necessary to set the parameters for each individual DC-

DC converter.

Up to 19 TEBECHOP bus converters combine and control up to 12

TEBECHOP devices in a group. The maximum number of controllable DC-DC

converters is limited to 99. (by the MCU 2500)



10.11.10 BGOE/COBS 66/73 4640 de

26 Satellite

The satellite integrated inside the DC-DC converter controls, regulates and

monitors the unit. For the user the satellite looks like a digital interface to the

DC-DC converter. The DC-DC converter obtains the required data via this

interface from other units of the MCU 2500 HDI remote monitoring system

to establish the desired operating state. This requires that the satellite has the

complete set of parameters for open and closed loop control as well as all data

relating to the operating states of the DC-DC converter.

The satellite is a principal unit in the MCU 2500 HDI remote monitoring

system, enabling power supply systems to be controlled and monitored via the

public telephone network.

The further functions of the satellite include the following:

(Faults are transmitted by the MCU 2500 HDI remote monitoring system)

1. Two adjustable operating modes

2. Unit monitoring with logically combined urgent alarm

3. Input voltage monitoring with logically combined non-urgent alarm (time delay of the alarms adjustable)

4. Voltage tracking (UrEG. adaptation)

5. Power management (Po.MA)

6. Serial SAT-Bus interface via mating plug and socket system for communication when several DC-DC converters are operating in parallel

26.1 Standard function

After switching on the DC-DC converter and an initialisation phase of

approximately 30 seconds, the unit runs up to the last saved output voltage.

27 Alarms

27.1 Alarm contacts

The following are located on the rear in the version equipment rack 5-way for

4x power modules, incl. MCU 2500 HDI remote monitoring system:

2x alarm terminals with voltage-free contacts.

Configuration by means of the TEBE MCU Service software,

see Description: 3293

Relay 1 (X104) and Relay 2 (X106),

screw terminals 1mm/ AWG 18,

max. contact loading:

30 V 2 A, AC/DC

27.2 Urgent alarm (unit fault SV1)

The Device fault alarm contact of the MCU 2500 HDI remote monitoring

system is closed in the event of a fault, and the green Operation / LED

lamps extinguish and the red Fault/ (unit fault) LED lights.

These signals are internally delayed by approximately 30 seconds.

Device fault (urgent alarm) is transmitted under the following conditions:

- Overvoltage protection has tripped

- Temperature too high

- Regulator or power stage defective

- Output fuse blown

27.3 Non-urgent alarm (mains fault SV2)

This signal follows AC undervoltage or mains power failure; the alarm contact

of the MCU 2500 HDI remote monitoring system is closed.

27.4 Overload detection/Overload behaviour

When the output of the DC-DC converter is overloaded or a short circuit

occurs, the 2-way rated current can be supplied for 2 seconds.

The consequence of current limitation if applicable is a drop of the output

voltage in the event of a short circuit to < 1 V

During this time, the short-circuit should be isolated through activating a fuse.

If after this time the short-circuit or overload are still present and the output

current does not drop to 100%, after approx. 5 seconds the output voltage is

switched off.

After the fault has been repaired, the unit can be restarted when it has been

isolated from the mains for about 10 s or it has been reset via the MCU 2500

HDI remote monitoring system.

Note: The rating of the fuse must be observed.

27.5 Temperature monitoring

The DC-DC converter is equipped with a temperature monitor on the heat sink

which operates as follows:

Assumption:

The DC-DC converter is operated at rated current.

1. Heat sink temperature continues to rise

2. At T > 122C DC-DC converter power is reduced

3. At T > 130C DC-DC converter is switched off

4. Red Fault/ LED (unit fault) illuminates

5. Green Operation/ LED extinguishes 6. Urgent alarm/Device fault SV1 is transmitted.

After the heat sink has cooled down, the DC-DC converter is

automatically reset. The DC-DC converter is then switched on

again.

27.6 Overvoltage protection

In the event of overvoltage (see technical data sheet) the unit is switched off.

The overvoltage protection is designed to protect the battery and the unit. After

the fault has been repaired, the unit can be restarted when it has been isolated

from the mains for about 10 s or it has been reset via the MCU 2500 HDI

remote monitoring system.

The red Fault/ LED (UA too high flashing rate 3 x) and urgent alarm are also reset by this action.

DC-DC converters 24 60V: internal hardware setting, additional shut down value (up to the set hardware shut down value) configurable by the software

DC-DC converter 110/220V: internal hardware setting (Poti).

It is not possible to test the overvoltage protection with an externally controlled power supply unit as the DC-DC converter

recognises an externally fed voltage and fails to switch off as a

result.

27.7 Fuse monitoring

An output fuse is already integrated for protecting the unit. The monitoring

system integrated within the unit initiates an alarm when the output fuse has

blown.

The red "Fault"/" " LED (Fault - Fuse, flashing) illuminates, the Device fault alarm contact of the MCU 2500 HDI remote monitoring system is

closed, and the green Operation / LED lamps extinguish.

27.8 Incorrect polarity

Output voltage 24-60V:

Incorrect polarity at the output is detected and the internal monitoring prevents

the DC-DC converter from being started.

Output voltage 110-220V:

Incorrect polarity at the output activates the integrated fuse.

27.9 Fan fault

When the fan is running (temperature- and current-controlled), an air-flow

monitor monitors the operation of the fan. In the event of a fault, the following

occurs:

Red Fault/ LED (Fault - Fan flashing 2 x in succession) illuminates, green "Operation"/ " " LED illuminates continuously

The fault code is transmitted via the SAT bus

Non-urgent alarm (SV2) is signalled with a time delay via the SAT-Bus to the MCU 2500 HDI remote monitoring system (for delay time,

please refer to the technical data sheet).

The output current is reduced automatically depending on the temperature.

In this way it is possible to continue to operate the unit (with reduced power).

28 Fuses

According to the technical data sheet.

Access to the input and output fuses is only possible after removing and

opening the unit.
