Alarm messages

The warning message appears periodically as A=Alarm/Warning and a three-digit in the display of the PMU A
warning cannot be acknowledged. It extinguishes automatically when the cause of the warning is eliminated.
Several messages may occur at the same time, in which case they appear one after the other in the display.
If the common rectifier is operated with the OP1S operator panel, the warning appears in the bottom line of the
display. The red LED starts blinking first (see the operating instructions for the OP1S)

Measure inlet air and/or ambient temperature. If ϑ >
40°C, note the reduction curves. See Section 14.1.
Check
- whether fan -E1(-E2) is connected and rotating in the
right direction.
- whether the air inlet and outlet openings are clean and
clear.
- the connection of the temperature sensor to -X30
(-X31, -X32).
With water-cooled units:
-
Water inlet temperature too high, cooling circuit
interrupted or cooling water pump faulty
Check whether the rated DC current of the
rectifier/regenerating unit is adequate for the specific
application.
