16 Status Display and Error
Messages of PS2
The 7-segment display shows status and error messages.
A status message is made up of 3 digits and displayed as sequence. All messages end
with dot behind the last digit. When the first digit is 'E.', there is a permanent error.
Examples:
1. Permanent display 3
▸
PS2 waits for mains supply.
2. Short-time display 2
▸
PS2 supply is in precharging mode of intermediate circuit.
3. Permanent display 1.
▸
PS2 is ready for operation.
▸
Dot indicates 'Mains phase monitoring OK'.
4.
▸
Mains supply disconnected, PS2 is still operating...
▸
Phase monitoring detected missing phase, parameterized switch-off
time is running.
5.
▸
Mains supply reconnected, PS2 is still operating ...
▸
All phases reconnected (indicated with dot), parameterized switch-
off time is running out, then the PS2 tries to switch on again with
precharging.

▸
PS2 is not switched on due to error E08.
▸
Parameter set of PS2 is not valid. (delivery status, please enter valid
parameters)
7.

PS2 is switched off due to error E02. Overvoltage occurred.
16.1 List of the Operating States
Code Description
−1 Ready for operation, input voltage missing (Monitoring of mains phases has detected miss-
ing phase, the device is waiting for reconnection during the parameterized switch-off time.)
−1. Mains phases reconnected (Switch-off time is running out, afterward the device is switched
on again.)
1− Fix restart time delay of approx. 7 seconds (for device version 2.000 and higher)
1. Power supply unit is ready for operation
2 Precharging is active
3 Waiting for mains voltage
8 Discharge of DC link via ballast resistor is active (up to 7 s or UB < 20 V
DC
)
9 No valid parameters (Set the parameters, please.)
