An alarm message cannot be acknowledged, but disappears automatically when the cause has been
eliminated.
Several alarm messages can be active at the same time, these are then displayed in succession.
Many alarm messages can only occur in certain operating states.
(see list of alarm messages)

•
Alarm message is displayed on the operator panel (PMU, OP1S)
•
B0114 ( = status word 1, bit 7) is set and B0115 is cancelled
(see also special alarm bits in status word 2, e.g. for an external alarm, overload, etc.)
•
The corresponding bit in one of the alarm words r953 (K9801) to r960 (K9808) is set
