Fault Remedy Valid for
Connection/
voltage error
Supply voltage not present. Apply supply voltage.
All
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.
No bridge between Y1 and Y2. Insert bridge.
Missing bridge between S10 and S11.
E.g., for two-channel emergency stop
wiring.
Insert bridge.
Cross-circuit
Between both enable circuits
S10/S11-S12 and S21-S22.
E.g., for emergency stop or safety
door.
Remove cross-circuit.
Between both enable circuits S10 and
S12.
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 S21 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.
Fault with
internal cause
Enable contact(s) of K1 faulty. Replace safety relays. All
