Operation
The PNOZmulti system is ready for operation when the "POWER" and "RUN" LEDs on the
base unit are lit continuously.

Internal error on the expansion module PNOZ m EF
1MM or on the overall system. Expansion module is in a
safe condition.

Behaviour with implausible sensor signals
Implausible sensor signals (e.g. frequency difference between Track A and B or the ratio of
AB to Z is not correct) do not lead to an FS stop of the PNOZmulti system.
However, the error is displayed through the LEDs at the device and through an error stack
entry. All the safety functions that refer to the Motion Monitoring area will be deactivated.
The global reset can be used to reactivate the safety function when feasible signals are
connected.
Depending on the case of an error and the applied frequency, the detection of an implaus-
ible sensor signal may take some time.
