14.7 Troubleshooting

The following table collects up a series of typical service situations, which are useful in order to understand and solve hypothetical faults or
malfunctions.
N.B.:
1. Before consulting the following table, check any signaling of error messages on the first line of the display for a few seconds.
2. FN indicates normal operation of the PR112.
3. In the case when the suggestions proposed do not lead to a solution of the problem, please contact the ABB SACE Assistance service.
