PSoff
Cause
–
Control ports STO-A and STO-B are not actuated simultan
eously.
Measure
Check discrepancy time.
Cause
–
Control ports STO-A and STO-B are not wired in the same way.
Measure
Check discrepancy time.
Cause
Upper and lower switch supply not simultaneously activated (dis
crepancy 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 faulty.
