2.2 Construction and principle of operation These power supply systems are designed to deliver an uninterruptible supply to DC loads. Rectifier units are used to convert electrical energy taken from the AC mains supply into a direct voltage for feeding the DC loads and the battery. The loads are fed from the battery when the AC mains supply fails. DC loads can be securely supplied with rated currents of 12,5/10 A at nominal voltages of 48/60 V. The equipment comprises the following cabinets: - power supply system - battery cabinet The individual components of a standard power supply system are: • Switched-primary rectifier units • Control and alarm unit SVS-SM7 • Facilities for measuring battery and load currents • Fuse-disconnectors for the connection of 2 groups of batteries • Deep-discharge protection (optional). • Temperature-dependent charging characteristic (optional)

All rectifier units are provided with supervisory facilities. The operational status of these units together with the most important system data for the complete equipment (e.g. the voltage to the loads and the current through the battery) are evaluated in the SVS-SM7 control and alarm unit and displayed in abbreviated plain language on a 16-character panel. The operational status can be interrogated, and the system parameters can be changed, with the aid of the keys on the SVS-SM7 or on an IBM-compatible PC connected to the RS232 interface provided. Several rectifier units can be operated in parallel in order to obtain a higher rated power. The subrack can be fitted with up to 6 rectifier units. All the necessary connection points to the units are arranged on the front of the equipment. The control and alarm lines are connected via a plug and socket. The cabinets are suitable both for free-standing installation and for mounting against a wall. Several systems can be installed adjacent to each other and bolted together in a row. It is also possible to install the SVS cabinet on top of a battery cabinet of the same design and bolt the two together. Appropriate installation kits can be supplied for this purpose.

2.3 Functional units In the following description, the LCD indications are given in a different typeface and for the most part are followed in parentheses by a full-text equivalent in italics. Blank characters in the display are represented here by underscore symbols „_“. 2.3.1 Rectifier unit The rectifier units are fed from the public electricity supply network. They convert the alternating voltage into a direct voltage. The modern switched-mode design used in the rectifier units achieves a high regulation accuracy with a high efficiency and at the same time leads to reduced dimensions and weight. The rectifier units are operated in standby mode in parallel with the battery. The necessary control voltages, commands and signals are fed to each rectifier unit by a ribbon cable which, depending on the type rectifier unit. Mounted next to the SVS-SM7control and alarm unit. 2.3.2 Control and alarm unit SVS-SM7 General The control and alarm unit is the central supervisory, control and alarm reporting facility for the power supply system. This unit acquires all the necessary measured values and operational status signals generated by the power supply system and initiates the necessary reactions by the equipment. The design of the SVS-SM7 unit enables the various control, alarm and supervisory requirements to be met without any software or hardware changes to the equipment. To this end, the SVS-SM7 unit must be configured before it is first put into service. The configuration data and all the limit values are stored in an EEPROM so that they are available each time that the equipment is switched on again. The configuration is protected by a password and can be accessed only by employees of SIEMENS. All limits and operating parameters are initialized meaningfully after the configuration has been carried out. Equipment owners are able to adapt these settings to their own requirements. This setting facility is also protected by a password which is made known to the owners. The SVS-SM7 unit comprises the printed-circuit board SVS-EA6 in double Europa card format and a front panel suitable for installation in a 19“ subrack. Screwed connector strips are provided on the front panel for the input and output connection lines.


A30050-X6301-X-4-7618 Page 9 of 47

An „Operat.“ („operation“) LED indicator and a „Fault“ LED indicator are also located on the front panel. The D-Sub connectors X3 provide for the direct connection of SIEMENS rectifier units. All the necessary signals between the rectifier units and between the SVS-SM7 and the rectifier units are carried by these connectors. The SVS-SM7 has 7 analog and 7 binary inputs, 1 analog output, 6 binary outputs and 1 RS232 interface.

2.31 - 2.40 V/cell charging characteristic control function. The contact closes when this charging characteristic is selected, either manually or by the automatic charging facility after the battery has been discharged. Not selecting a charging characteristic results in the automatic selection of the float charging characteristic (2.21 - 2.30 V/cell). 4 SV1 alarm

Alarm contact: equipment fault.

The internal relay in the SVS-SM7 releases for the following faults: • when one of the monitored voltages is too high or too low, • when an equipment fault is present

("Mains Failure" and "No Rf. in Oper." are NOT equipment faults). The X2.1-21 and X2.1-22 (of SM7) terminals are closed for a fault. 5 SV2 alarm

Alarm contact: battery discharging The alarm is delayed; the amount of delay "tSV2Dly" can be preset. The internal relay in the SVS-SM7 is energized when: • the battery is discharging (AC mains supply failure or no rectifier in operation). The X2.1-24 and X2.1-25 (of SM7) terminals are closed for a fault. 6 Deep-discharge protection

Control function: battery connected, battery disconnected.

The internal relay in the SVS-SM7 is energized, and the deep-discharge protection contactor releases, when: • the load voltage and the battery voltage fall below a preset value.


A30050-X6301-X-4-7618 Page 13 of 47

2.3.2.5 Operating card (integrated in the control and alarm unit) All measured values and operational conditions from the SVS-SM7 control and alarm unit are displayed by the 16-digit panel on the operating card. Operating conditions can be displayed and system parameters changed either by using the keys or by connecting an IBM-compatible PC to the RS232 interface socket. LED indicators also display the conditions „Operation“ (green) or „Fault“ (red). The interface RS232 is potential-free. 2.3.3 Deep-discharge protection To protect the battery connected to the SVS system from being discharged beyond a specified limit, it is disconnected from the system when the battery terminal voltage falls below a preset threshold. A special contactor is connected in the connection to the battery for this purpose. The battery is disconnected when the battery and load voltage falls below the preset value Ub_Sw.Off. The battery is reconnected and recharged when the load voltage rises above the preset value Ul_Min. 2.3.3.1 Isolating blade terminal The switching contact integrated into the SVS-SM7 control and alarm unit for the control of the deep-discharge protection circuit breaker can be short-circuited by inserting the isolating blade terminal. This plug protects the loads against an accidental interruption of the DC supply during maintenance work on the SVS-SM7 control and alarm unit.

2.4 Operating conditions 2.4.1 Charging characteristic control

The equipment can be operated with a choice of charging characteristics. Charging characteristic for parallel operation (2.06 V/cell) This charging characteristic is required when sensitive loads with a narrow voltage tolerance are being supplied. All the paralleled rectifier units are hard-switched to 2.06 V/cell. This charging characteristic can be manually activated from the keypad of the operating card while the SVS-SM7 is in the "Calibr." [setting] mode. The rectifier units are switched to this charging characteristic automatically when a battery availability test is started. Charging characteristic for float charging (2.21 to 2.30 V/cell) All rectifier units are switched to this charging characteristic for normal operation. The value of float charging voltage required depends on the type of battery connected. The value of voltage per cell appropriate for the battery in use can be set in the “Calibr.” menu of the control and alarm unit SVS-SM7.


A30050-X6301-X-4-7618 Page 14 of 47

Charging characteristic for recharging (2.31 to 2.40 V/cell) To shorten the recharging time for the battery, all the rectifier units can be switched to the 2.31 to 2.40 V/cell charging characteristic. The value of recharging voltage required depends on the type of battery connected. The value of voltage per cell appropriate for the battery in use can be set in the "Calibr." [setting] menu of the control and alarm unit SVS-SM7. 2.4.2 Temperature-dependent charging voltage The power supply system is fitted with a temperature compensation facility to make it possible to correct the float charging voltage according to the temperature of the battery. The float charging voltage is varied in inverse proportion to the battery temperature in accordance with a temperature coefficient. The float charging voltage is reduced when the battery temperature rises and increased when the battery temperature falls. The temperature factor must be set to match the battery type if the battery is changed. NOTE: Observe the battery manufacturer's instructions. 2.4.3 Charging characteristic compensation The rectifier unit voltage characteristics are regulated by the control and alarm unit SVS-SM7 in accordance with the operating conditions of the system. Changing the settings of the charging characteristic potentiometers in the rectifier units has no effect on the output voltage when operating with the control and alarm unit SVS-SM7 (control cables plugged-in). Therefore: Do not change the settings of the potentiometers in the rectifier units! The function of the output voltage regulation can be enabled or disabled in the Calibr. menu. If the function is activated, the load voltage of the system will be regulated to the preset value of the system via the temperature compensation input of the rectifiers. Attention: If the controller cable X3 of the SM7 is removed, the regulation loop is broken. This

might have the result that by connecting X3 again, the system could get a voltage peek of about 5V. To avoid this, the user should deactivate the output regulation function before disconnecting X3 from the SM7. This will be done in the menu “Calibr.”, Submenu “Calibr. voltage”, option “Set Ul.reg”. After reconnecting X3 to the SM7, the output voltage regulation may be activated again.


A30050-X6301-X-4-7618 Page 15 of 47

2.4.4 Automatic charging All the rectifier units are hard-switched to the charging characteristic for float charging (2.21 to 2.30 V/cell) in normal operation. If the battery is discharged for longer than the preset time "tMains F" (i.e. during a failure of the AC mains supply, after all rectifier units have failed or during a battery availability test), all the rectifier units will be switched to the recharging characteristic (2.31 to 2.40 V/cell) once they are again in operation. If during this charge the battery terminal voltage reaches the preset value "UChg End", the battery will continue to be charged for the preset time "tBattChg". Thereafter, the rectifier units will be switched back to the charging characteristic for float charging (2.21 to 2.30 V/cell). 2.4.5 Battery availability test (BT) (optional) The battery availability test (BT) is carried out with the rectifier units switched to a standby condition. They are ready for operation but supply no power and the load current is taken entirely from the battery. The system remains in this condition until the test period has expired or until the battery voltage has fallen to the preset value "UBT.End". After this, the rectifier units supply the load again without delay. There are three different ways to start the battery availability test (BT): • automatic BT • manual BT • BT after detection of battery asymmetry The duration of the battery availability test is set to match the period of autonomy required from the system battery. 2.4.6 Automatic BT The battery availability test (BT) is started automatically at the preset interval "tBT.Rep". The recommended value for the duration of the automatic test "tBT.auto" is about one third (1/3) of the period of autonomy required from the system battery. If the battery terminal voltage at the end of the test is below the preset value "UBT.End", the fault message "BT negative" appears on the operating card display panel. The equipment alarm SV1 is given and latched. It must be reset via the operating card keys to clear the display. 2.4.7 Manual BT The capacity of the battery can be checked at any time by activating the manual battery availability test from the operating card keys. The recommended value for the duration of the manual test "tBT.manu." is about one twentieth (1/20) of the period of autonomy required from the system battery.


A30050-X6301-X-4-7618 Page 16 of 47

If the battery terminal voltage at the end of the test is below the preset value "UBT.End", the fault message "BT negative" appears on the operating card display panel. The equipment alarm SV1 is given and latched. It must be reset via the operating card keys to clear the display. 2.4.8 Battery availability test with asymmetric battery The individual voltages at the terminals of the battery blocks forming a battery group can differ from each other if the battery is left for a long time without a load. A load test can eliminate the asymmetry. The test will run for the preset time "tBT.Asym" after the BVT function is activated. The "Battery Asymetr" fault indication is disabled during this time. The fault indication is again enabled if the battery still shows asymmetry after completion of the test. The "B.Asym after BT" fault is displayed and latched. It must be reset via the operating card keys to clear the display. 2.4.9 Battery circuit monitor (optional) Measurement of asymmetry The voltage at the battery center-tap is continuously compared with one half of the voltage to the load. An SV1 alarm is given and the "Battery Asymetr" fault is displayed on the operating card whenever the difference between these two voltages exceeds the preset value "Ub Asym". If the battery availability test was enabled during the configuration of the equipment, the alarm is initially suppressed and the battery test is started. The alarm is re-enabled if the battery is found to be still asymmetrical after the battery test has been completed. 2.4.10 Battery charging current limiting The maximum battery charging current can be preset in steps that are 10% of the rated current. This allows the charging current to be restricted to the maximum permissible charging current specified by the battery manufacturer. 2.4.11 Emergency operation Releasing relays will set the power supply system into a safe condition if the control and alarm unit SVS-SM7 should fail. Under those circumstances, all rectifier units and the battery remain switched on and the charging characteristic is switched to 2.23 V/cell. The SV1 (equipment fault) and SV2 (battery discharging) alarms will be given.


A30050-X6301-X-4-7618 Page 17 of 47

2.4.12 Maintenance break point The contact in the control and alarm unit SVS-SM7 that is used to drive the deep-discharge protection circuit breaker can be short-circuited by inserting a blade between the terminals provided. This protects the load from an unintended interruption of the supply during repair work on the control and alarm unit SVS-SM7. 2.4.13 Deep-discharge protection To protect the battery connected to an SVS system from a deep discharge, it is disconnected from the system when the voltage falls below a preset deep-discharge threshold. A DC circuit breaker is connected in series with the battery for this purpose. The battery is disconnected when the battery terminal voltage and the load voltage fall below the preset value "UB SwOff" [disconnect battery]. The battery is reconnected and recharged as soon as the load voltage increases above the preset value "Ul Min" [load voltage low]. 2.4.14 Battery and deep-discharge protection monitor An SV1 alarm is given when the difference between the battery terminal voltage and the load voltage exceeds 1.5 V. The "B.1 Fuse Failure" [battery 1 fuse-disconnector open] or "B.2 Fuse Failure" [battery 2 fuse-disconnector open] fault is indicated on the operating section display panel or on the PC screen. This warns that the connection to the battery has been interrupted (e.g. by a blown fuse or by the deep-discharge protection circuit breaker opening). The „fault“ LED lights.

3.2.6 Temperature sensor When a battery cabinet is used, the temperature sensor is attached by a mounting device inside the upper third of the cabinet. Pass the connection cable through the rubber grommet in the SVS cabinet and connect it to the plug X2.1:12, 13 on the control and alarm unit SVS-SM7. If the battery is free-standing, the temperature sensor is attached to the outside of one of the cells.

3.3 Switching on Check the following conditions before switching on the power supply equipment with the AC mains supply and the battery: 1. The battery fuse-switch disconnectors are open. 2. The load circuit breakers are open. 3. The rectifier unit output circuit breakers and input circuit breakers (AC mains supply circuit breakers) are open. 4. The rectifier units are set for the system nominal battery voltage (check the 24/48/60 V selector switch through the case-opening on the right side of each unit). 5. The AC mains supply input connectors are in place and the DC output connections have been made with the correct polarity. 6. The 15-way ribbon cable is not connected to each of the rectifier units. IMPORTANT: Accidental contact between the pins of the Sub-D connectors on the 15-way ribbon cable and ground could damage the equipment. Therefore always handle the connectors carefully and fit them with protective caps when they are not plugged in. 3.3.1 Connecting the battery 1. Connect the system battery through to the SVS equipment by inserting the battery fuses. 2. The SVS-SM7 control and alarm unit equipment will now receive operating supply via the printed card for fuse SVS-SI1 in the cabinet. WARNING: The battery continues to supply current to the SVS-SM7 control and alarm unit even when the rectifier units are switched off. Disconnect the supply from the SVS-SM7 by removing the plug from printed card for fuse SVS-SI1 to prevent the battery from being discharged.


A30050-X6301-X-4-7618 Page 25 of 47

3.3.2 Connecting the rectifier units and deep-discharge protection 1. Insert the AC mains supply fuses to switch on the rectifier units, one after the other. The red LED „Operat.“ (operation) indicators on the rectifier units will light after a short delay. Check the DC output voltage from the rectifier units at their output terminals with a multimeter. 2. Close the output circuit breakers on the rectifier units. The rectifier units will deliver an output voltage to the busbar. The SVS-SM7 control and alarm unit will measure the voltage and will then close the deep-discharge protection circuit breaker. The battery is now connected to the load busbar. 3. Configure the rectifier units from the PC or the operating card connected to the RS 232 interface on the SVS-SM7 control and alarm unit. 4. Connect the rectifier units to the SVS-SM7 control and alarm unit by plugging on the 15-way ribbon cables. WARNING: Accidental contact between ground and the pins of the Sub-D connector on the ribbon cable can damage the equipment, therefore handle them carefully and insulate any unconnected plugs with their protective caps. NOTE: The rectifier unit charging characteristics are regulated via the SVS-SM7 control and alarm unit in accordance with the operational status of the equipment. Altering the potentiometers in the rectifier units while an SVS-SM7control and alarm unit is in use (control cable connected) will not have any effect on the rectifier unit output voltage. Therefore, do not readjust the potentiometers in the rectifier units.

3.4 Operating the power supply equipment The SVS-SM7 control and alarm unit can be operated and configured either from the operating card or from a PC with terminal program. General equipment data (e.g. measured values) can be read out and system parameters (e.g. threshold values) can be changed via the RS232 interface on the SVS-SM7 control and alarm unit. Either the operating card or the terminal are connected to the serial interface on the RS232 interface on the SVS-SM7 control and alarm unit. For the connection between the SVS-SM7 and the computer a null-modem cable is needed (9 pin to 9 pin, RxD, TxD crossed over). Set the following parameters on the terminal program: • Data transmission rate : 9600 baud • Number of data bits : 8 • Number of stop bits : 1 • Number of parity bits : none

1 Construction and principle of operation The rectifier units are used to generate a voltage to charge or float charge the battery and to feed sensitive DC loads. The input to the rectifier unit is taken from the public AC mains supply. The rectifier unit converts the alternating voltage into a direct voltage.

The rectifier unit consists mainly of a step-up (Boost) converter which is fed from the AC mains supply via a bridge rectifier, a DC-DC converter which converts the intermediate circuit voltage to the required output direct voltage, the output filter and the electronic regulation, control and supervision circuits.

The bridge rectifier rectifies the input voltage that is taken from the AC mains supply. The input filter minimises the high frequency interference that might otherwise find its way back into the public AC mains supply.

The step-up converter is controlled by the shape of the AC mains supply voltage in such a way that the current drawn by the rectifier unit is sinusoidal.

The electrical isolation between the AC mains supply and the rectifier unit output takes place in the DC-DC converter. The intermediate circuit voltage is converted there into the desired output direct voltage.

The high frequency (100 kHz) with which the internal power semiconductors are switched ensures that a high dynamic regulation is obtained with a very good efficiency and practically silent operation.

The rectifier unit can be set for one of three nominal voltages: 24 V, 48 V and 60 V.

The current-limiting circuit becomes active if the rectifier unit is overloaded or if a load is short-circuited. The output current is limited to the rated current to prevent an overload of the intermediate circuit.

All the necessary connections are made on the front of the rectifier unit. The power connections are protected against electric shock through accidental contact.

The rectifier unit is protected on the DC and AC sides by power circuit breakers (external).

The rectifier unit is designed for a single-phase input and is cooled by internal fan.

Several rectifier units may be connected in parallel. The load is shared equally amongst the paralleled units (sloping characteristic).

2 Settings General Ensure that the test equipment is free of ground for all measurements. Measurements with the oscilloscope may be carried out only when the oscilloscope is either connected to the AC mains supply via an isolation transformer or is operated with an isolation amplifier. The three potentiometers which are located on the front panel of the rectifier unit are used to set the voltage per cell:

potentiometer 2.06 V/cell potentiometer 2.23 V/cell potentiometer 2.40 V/cell.

The switch for setting the required output voltage (accessible through an opening in the case) is located on the Control-Unit:

No. of cells Volts/cell Nominal value Setting range

12 2.06 24.8 V 21V ... 34V

12 2.23 26.8 V 24V ... 31V

12 2.40 28.8 V 24V ... 31V

24 2.06 49.6 V 41V ... 68V 24 2.23 53.5 V 48V ... 62V

24 2.40 57.6 V 48V ... 62V

30 2.06 62.0 V 52V ... 84V

30 2.23 67.0 V 59V ... 77V

30 2.40 72.0 V 59V ... 77V

The current limiting is set automatically to the appropriate value when the desired nominal voltage is selected.

3 Rectifier unit supervision

Supervision Explanation Reaction

ZKF Intermediate circuit supervision: is activated when the intermediate circuit voltage falls below 350V

latched shutdown

NF AC mains supply failure: is activated when the AC mains supply voltage falls below 155V

shutdown

OV2F UA MAX (Umax)

Overvoltage supervision: is activated when the output voltage exceeds the reference voltage set with potentiometer Umax : 75V/60V/30V.

latched shutdown

OV1F UA MAXSEL

Selective overvoltage supervision: is activated and shuts down only the rectifier unit that is responsible for the overvoltage (the threshold is 2 V lower than the threshold for the non-selective supervision).

latched shutdown

UVF UA MIN (Umin)

Undervoltage supervision: is activated when the output voltage falls below the reference voltage set with potentiometer Umin : 57V/45V/23V.

not shutdown

Fan Fan supervision: is activated when the fan is blocked or because of parting a cable of the fan.

not shutdown

Temperature Temperature supervision:

is activated when the transformer TR2 temperature is too high (125°C).

latched shutdown

Remarks: Shutdown: The rectifier unit switches off automatically (�Operat.� LED goes out, �Fault� LED lights) but switches back on again automatically when the fault is no longer present. Latched shutdown: The rectifier unit switches off automatically (�Operat.� LED goes out, �Fault� LED lights) but does not switch back on again automatically when the fault is no longer present. The rectifier unit must be unlatched when the fault is no longer present by manually switching it off and then on again.


A30050-X6302-X-3-7618 Page 8 of 12

Not shutdown: The rectifier unit remains switched on (�Operat.� LED remains lit, �Fault� LED lights).

4 Alarms LED indicators There are two LED indicators on the front panel:

Component Function

green LED LED indicator �Operat.� (Operation)

red LED LED indicator �Fault�

The two LED indicators light simultaneously when an undervoltage is detected at the output and when the fun is blocked.

Relais signals SV1 and SV2

The LED indicator �Fault� lights on the front panel of each rectifier unit and the remote alarm floating changeover contact SV1 changes condition to give a general alarm under the following conditions:

• fault in the intermediate circuit

• overvoltage

• selective overvoltage

• undervoltage

• overheating (high temperature)

• fan defect

The �battery discharging� alarm floating changeover contact SV2 in each rectifier unit changes condition to signal a failure of the AC mains supply at the input.

No alarms are given while the rectifier unit is switched off.

Both SV1 and SV2 alarms are given when the AC mains supply at the input fails and the battery voltage is no longer present.

5 Testing electric properties

5.1 Measuring DC voltage:

Disconnect temperature sensor (pin X2.1-12/13) to disable temperature dependent voltage correction

Open battery fuses

2,23V/C characteristic (factory setting): UOUT=53,5V@48V and 67V@60V

Switch characteristic manually (with SM7, see documentation, section 3.4.3.3) to 2,06V/C characteristic: UOUT =49,6V@48V and 61,8V@60V

Switch characteristic manually (with SM7, see documentation, section 3.4.3.3) to 2,33V/C characteristic: UOUT =56,0V@48V and 70V@60V

Switch characteristic manually (with SM7, see documentation, section 3.4.3.3) to automatic mode => UOUT =53,5V@48V and 67V@60V

Switch off all rectifiers

5.2 Test current limiting:

Switch on only one rectifier

Switch on load and adjust maximum current; the output current should be between 12-13A,

If not, adjust output current with potentiometer IMAX on the rectifier modules

Repeat this step for all rectifier modules

REMARKS

5.3 Measuring current sharing:

Switch on all rectifier modules; adjust load to half of the maximum output current

Measure the output currents of the single rectifier modules with a clamp-on-ammeter; the maximum deviation should not exceed 1,5 A;

6 Testing the signals and supervision

6.1 Testing under voltage detection and battery disconnection:

Adjust limits for under voltage detection and battery disconnection with SM7 (see documentation section 3.4.3.2) factory settings: 46V respective 44V @48V and 56V respective 54V @60V

Disconnect battery (open fuses); ignore fault message;

Increase test load until output voltage decreases

The SM7 signals "UL too low", the LED´s "Fault" and "Operation" lit on rectifier modules and SV1 is provided when the UOUT < response value for under voltage detection;

Continue increasing test load;

The SM7 signals "Ub too low", the LED´s "Fault" and "Operation" lit on rectifier modules and SV1 is provided when the UOUT < response value for battery disconnection; the battery contactor disconnects;

6.2 Testing over voltage protection:

Adjust limits for over voltage protection with SM7 (see documentation section 3.4.3.2) factory settings 61V@48V and 76V@60V

Switch on voltage stabiliser and increase output voltage. When response value for over voltage protection is exceeded the rectifier modules are switched off locked;

The SM7 signals "Ulnorm too high"

SV1 alarm is provided

Unlock rectifiers by resetting system with SM7 (see documentation section 3.4.2.2)

Close battery fuses
