Troubleshooting
6.1
Error messages on Displays
Error messages during operation
Display:
Meaning:
SAFETYLOOP
Safety loop (Interlock) is not closed.
EXTERNAL INHIBIT
High voltage cannot be generated because of external inhibit (analogue I/O).
EMERGENCY
High voltage has been shut down without ramp due to Emergency Off.
CURRENT TRIP
Current set value reached during Kill enable. High voltage has been shut down without
ramp.
VOLTAGE LIMIT
Voltage Limit V
max
has been exceeded.
In mode Kill enable, the high voltage is shut down without ramp.
CURRENT LIMIT
Current Limit I
max
has been exceeded.
In mode Kill enable, the high voltage is shut down without ramp.
OVERTEMPERATURE
High voltage has been shut down because of over temperature.
Let device cool down.
ERROR SUPPLY
Internal voltage supply faulty. Device must be shipped to service.
ERROR SERVICE
Internal failure. Device must be shipped to service.
Error messages during boot
Display:
Meaning:
ERROR RTC
Real time clock battery is low. Contact service.

6.2 Further Errors
Table 6.1: Further Errors
Unit does not provide output voltage, and the
displays are not lightning
⇒
- Check supply voltage and connection
Unit does not provide output voltage but the dis-
plays are lightning
⇒
- Check environmental temperature (T
U
≤
35°C)
- Check control
- Check INHIBIT function
- Check safety loop
External fuses trip during switch on.
⇒
- Use fuses with slow characteristic
(inrush current 25 A)
If these instructions do not lead to a good result, this unit must be checked by an authorised agent or
shipped to the factory.
