Uok
Once the PSU Enable signal is applied, the DC output will turn on. The output voltage is internally
compared to the set reference voltage. If this is correct, the Uok indicator will turn on.
Note: If the external voltage is not correct, the DC output is turned off and the FAULT indicator turns
on. Check the external wiring.
TEMPW
This indicator warns that the internal temperature is too high. Check that the coolant flow and
temperature are correct. The TEMPW signal is also available as a status signal on pin 8 of the
auxiliary interface connector.
Important!
If no action is taken and the internal temperature continues to rise, the
FAULT
indicator
turns on and the DC output is turned off.
FAULT
This indicator turns on when corrective action is required. At the same time DC output is turned off.
Switch off the three-phase mains supply to reset the power supply.
If faults are detected, one or more status indicators will be off or displaying red/amber. Disconnect and
reconnect the mains supply to restart the power supply. For a status indicator explanation, refer to the
following table.
