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. [. . . ] Procedure: Disconnect the load and the battery, if applicable, on the output. Page 11 of 21 0206 BAL, en i Switch Mode Power Supply AC 2000 / DC 2000 - Set the required monitoring values with the UA> and UA< potentiometers with a screwdriver: - UA> Adjustment: - set the UA> potentiometer to the far right stop, set UA to the required UA> value, turn the UA> potentiometer to the left until UA> responds - UA< Adjustment: Performed as for UA> adjustment (observe the discharge time of the output capacitors and monitoring delay). Connect the load/battery Set the UA output voltage to the required value with the UA potentiometer. The maximum output current is also adjustable within a limited range with the IA potentiometer. - Procedure: Increase the load until the set current limitation is triggered Adjust the IA potentiometer with a screwdriver (IA smaller when turned to the left). 5. 3 5. 3. 1 Monitoring Mains Monitoring The mains monitoring assembly fulfils various functions. It ensures the intrinsic safety of the unit against overloads and overvoltages with fixed switching point settings. The response values (switching points) are given in the technical data sheet. On Hysteresis (Shutd ow n hysteresis ra ng e) Off U ma ins[V] Overvolta g e Und ervolta g e Figure 3 Mains undervoltage monitoring The unit is switched off if the mains supply drops below the switching point. When the hysteresis voltage is exceeded the unit automatically resumes operation with a "soft start". Page 12 of 21 0206 BAL, en Switch Mode Power Supply AC 2000 / DC 2000 Mains overvoltage monitoring When the maximum permissible mains voltage is exceeded, the SMPS is stopped for the duration of the overvoltage. When the voltage level drops below the hysteresis voltage the unit automatically resumes operation with a "soft start". 5. 3. 2 Output Monitoring The setting potentiometers and the LED indicators for the following monitored functions are located on the front plate: Overtemperature monitoring AC 2000 with deactivation, without latching. When the unit has cooled down it automatically resumes operation with a "soft start". Fault, with deactivation and latching - DC overvoltage indicator UA> - with deactivation and latching (response delay t = 10ms) Adjustment with UA> potentiometer - DC undervoltage indicator UA< - AC2000 without deactivation, without latching DC2000 with deactivation and latching (response delay t = 2. 8 s) Adjustment with UA< potentiometer - Operation indicator lights up when power is supplied 5. 3. 3 Reset Buttons/Functions A fault signal (response of an output monitoring device) can be acknowledged with the "Reset" button. 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 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). 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.
