Display fault / Clear Fault Function
Display fault
The occurrence of a fault is indicated by the Fault LED on the front panel of the device or by an
isolated contact at the terminal block. The LED flashes if faults are pending. If faults are no longer
pending, the LED turns to steady light.
To display fault texts, you must press the CLEAR / FAULT key. After you have pressed this key, the
display field shows error and the bottom line shows the fault texts at 3-second intervals. All
messages are consecutively shown in the display field. As long as the Fault LED flashes, there is
still at least one fault pending. If the Fault LED shows steady light, all indicated fault messages are
no longer valid and the device has returned to fault-free operation.
Clear fault
The time and date of the fault occurred are shown in the fields R3 and R4. If there is more than one
fault pending, the time and date of the first fault occurred are shown.
