Siemens 6RA70 specifications Alarm messages

9.2Alarm messages

Alarm message display:

On the PMU: A (Alarm) and a three-digit number. The red LED (Fault) flashes.

On the OP1S: On the bottom line of the operational display. The red LED (Fault) flashes.

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 alarms (see List of Alarm Messages) can only be active in certain operating states.

The system responses to an alarm are as follows:

•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
