Fault and Alarm Messages

When a fault or alarm is generated, it is displayed immediately on the PMU as well as on the optional OP1S
(see Section 6.3, Figure 6.3). An alarm disappears automatically from the display when the problem has been
corrected. A fault message must be reset by pressing the P key on the PMU or the reset key on the OP1S after
the problem has been corrected, before it is possible to return to a normal operating state.
A current fault message or alarm can be "moved into the background" by pressing the P +  keys on the PMU
simultaneously, in order to parameterize or to read the fault value via r949.001. Acknowledgment of a fault
message "placed in the background" is not possible via OP1S either. You must have the fault message
displayed on the display of the PMU again by pressing P + ↓ before you can acknowledge it. Via the optional
operator panel OP1S, in spite of an active fault message or alarm it is still possible to parameterize. If no key
is pressed on the PMU for 30 s, the fault message which was moved into the background or active alarm
appears automatically on the PMU. The message can be brought back into the foreground by simultaneously
pressing the P + ↓ keys on the PMU at the parameter number level.
