15 Appendix
51-6 FSM: unequal serial
number Cause:
Serial number of currently inserted safety module
is different from the stored serial number.
Measure:
Error only occurs after replacement of the FSM
2.0 – MOV.
After module replacement: Module type not yet
accepted. Accept currently inserted FSM 2.0 –
MOV. Check the parameterisation of the FSM
2.0 – MOV in view of the application, since the
modules have been replaced.
Group 52: FSM 2.0 STO
52-1 FSM: discrepancy time
expired Cause:
Control ports STO-A and STO-B are not actuated
simultaneously.
Measure:
Check discrepancy time.
Cause:
Control ports STO-A and STO-B are not wired in
the same way.
Measure:
Check circuitry of the inputs.
Cause:
Upper and lower switch supply not
simultaneously activated (discrepancy time
exceeded)
- Error in control / external circuitry of safety
module.
- Error in safety module.
Measure:
- Check circuitry of the safety module – are the
inputs STO-A and STO-B switched off on two
channels and simultaneously?
- Replace safety module if you suspect it is
defective.
52-2 FSM: STOA/STOB
deactivated while power
output stage enabled Cause:
Failure of driver supply voltage with active PWM.
Measure:
The safe status was requested with power output
stage enabled. Check integration into the safety-
orientated wiring.
