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

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.
