persons working with or on the switch mode power supply prior to installation and initial start-up. These operating instructions are a composite part of the switch mode power supply. [. . . ] The unit then resumes operation if it was switched off. A fault signal can also be acknowledged by switching off the mains voltage or with the external on/off function. 5. 3. 4 Signalling The faults are indicated by LEDs on the front panel and signalled on signal connector X11 as a collective signal via a potential-free relay contact (changeover contact) (refer to circuit diagram). The contact between X11:12 and X11:13 is closed in the event of unit failure. Relay contact load: Umax = 110 V DC Iper < 0. 45 A DC Umax = 60 V DC Iper < 1 A DC Umax = 24 V DC Iper < 8 A DC Maximum isolation from the secondary side: 110 V DC Page 13 of 21 0206 BAL, en Switch Mode Power Supply AC 2000 / DC 2000 6. Parallel Operation Due to the inclination of the voltage step of approximately 1% a load distribution of approximately 10% is achieved in parallel operation of several SMPS units. If load distribution is to be optimized the output voltage of the unit with the lowest load current should be increased and the output voltage of the unit with the highest load current decreased. Selective monitoring of the individual SMPS units is only possible with external isolating diodes in the output. Systems with redundancy As the units can be connected in parallel it is possible to create systems for redundant operation in accordance with the n+1 principle. 7. Separate Networks When the SMPS is connected to separate networks, mains overvoltages must be expected which can last for a period of seconds. For example if rotary converters are used for supply, up to 20% overvoltage over a period of seconds occurs. The SMPS is protected against this overvoltage. The mains overvoltage monitoring device (refer to 5. 3. 1) stops the unit for the duration of the overvoltage. 8. 8. 1 Signal Interface (X11) External On/Off The unit can be switched on and off externally via a potential-free contact (contact load 15 V DC/5mA, contact open = "Unit Stop"). To this purpose the bridge on signal connectors X11:7 and X11:8 must be removed and a relay contact looped in (refer to Chapter 5. 1). The contact is connected galvanically with the unit output. The potential of X11:7 and X11:8 is applied to - UA. In the case of positive pole earthing the potential - UA which is now higher (in relation to reference potential) is applied to these inputs. Electrical isolation must therefore be carried out by the external relay. 8. 2 External Sensor Lead Output Voltage UA On all units is possible to compensate a voltage drop of 1 V on both the positive and negative output cables. For compensation on the positive output cable X11:9 is connected to the positive pole of the load, for compensation on the negative output cable X11:10 is connected to the negative pole of the load. If the sensor lead is interrupted the output voltage increases by 1 V.

In the "int" position the unit works in basic mode with the output voltage and current values stated in the technical data (refer to Chapter 11). In the "ext" position the output voltage can be adjusted with an external set value input. The "external" setting is indicated by a yellow LED on the front of the unit. The current set value function is set at the works to the internal set value and can be switched to an external set value input if required. The set value setting for voltage and/or current is performed on signal connector X11 with the signals shown in the circuit diagram (refer to Chapter 5. 1).
