13.7 Troubleshooting PR123/DC unit
The following table lists a series of typical service conditions, to help you understand and solve hypothetical faults or malfunctions.
Note:
1.
Before consulting the following table, check for any error messages appearing for some seconds on the display.
2.
FN indicates the normal operation of the PR123/DC.
3.
In the case where the suggestions proposed do not lead to a solution of the problem, please contact the ABB SACE assistance service.
