Display of faults and remedial actions

The exact cause of the fault is output by the "SF" LED as a flashing code. The following overview
shows the meaning of the flashing codes and their priority order. Priority order means that if
several faults are present at the same time, the fault with the highest priority is displayed. The
highest priority corresponds to the top entry in the overview.
8.4.1

Undervoltage at A1-A2

The device has detected undervoltage faults at A1-A2.
Remedy:
Apply auxiliary voltage at proper level.
8.4.2

Wire break / offset at L2

A wire break or a DC voltage offset greater than the set threshold U
detected.
This fault must be acknowledged, i.e. even after the fault has been eliminated, the device
remains in the fault state until it has been acknowledged by bridging terminals X2-X3.
8.4.3

Wire break / offset at L3

A wire break or a DC voltage offset greater than the set threshold U
detected.
This fault must be acknowledged, i.e. even after the fault has been eliminated, the device
remains in the fault state until it has been acknowledged by bridging terminals X2-X3.
