13.7. Troubleshooting PR122/P 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 PR122/P.
3. In the case where the suggestions proposed do not lead to a solution of the problem, please contact the ABB SACE assistance
service
