Fault
Remedy
Connection/
voltage error
○
○
○
Supply voltage not present.
Apply supply voltage.
●
○
●
Supply voltage too low.
Adjust supply voltage.
●
○
○
●
○
○
The enable circuits are connected incorrectly
or not connected at all.
Check the connection of the enable
circuits.
Cross-circuit
●
○
●
Between both enable circuits S11- S12 and
S11-S22.
Error detection on next demand.
E.g., for emergency stop or safety door.
Remove cross-circuit.
●
●
○
Between both enable circuits S11- S22 and
S11-S12.
Error detection on next demand.
E.g., for emergency stop or safety door.
●
○
○
Between both enable circuits S12 and S22.
The fault is not detected by the module itself.
E.g., for light grid type 4.
Short circuit
○
○
○
Between contact points A1 and A2.
Remove short circuit.
●
●
○
Between S11 and S12.
Fault detection on next demand.
●
○
●
Between S11 and S22.
Fault detection on next demand.
Fault in reset
circuit
●
○
●
Faulty reset button.
Short circuit between S33 and S34.
No fault detection on initial start, only on first
new demand.
Remove short circuit.

internal
cause
●
○
●
Enable contact(s) of K1 faulty.
Replace safety relays.
●
●
○
Enable contact(s) of K2 faulty.
