Power K1/K2 K3(t)/K4(t) Fault Remedy
Connection/
voltage error
○ ○ ○ Supply voltage not present. Apply supply voltage.
★ ○ ○ Supply voltage too low. Adjust supply voltage.
★
1 s
○ ○ Supply voltage too high. Adjust supply voltage.
★ ○ ○
The enable circuits are connected incorrectly
or not connected at all. Check the connection of the
enable circuits.
Cross-circuit
★
1 s
○ ○
Between both enable circuits S11-S12 and
S21-S22.
E.g., for emergency stop or safety door.
Remove cross-circuit.
★ ○ ○
Between enable circuit S12-S22 for applica-
tions with light grid and safe PLC.
Fault is detected and indicated by the light grid/
PLC.
Short circuit
○ ○ ○ Between contact points A1 and A2.
Remove short circuit.
★
1 s
○ ○
Between S11 and S12.
Error detection on next demand.
★
1 s
○ ○
Between S21 and S22.
Fault detection on next demand.
Fault in reset
circuit ★
1 s
○ ○
Faulty reset button.
Short circuit between A1 and S34.
No fault detection on initial start, only once all
enable contacts have been opened.
Remove short circuit.
Configuration
error
★
1 s
★
1 s
○
If a cross-circuit or overvoltage/undervoltage
occurs during the configuration phase, the
safety module indicates a configuration error. Check the wiring and the operat-
ing voltage supply.
Perform a voltage reset.

○ ○ Safety relay faulty.
Replace safety relays. Perform a
voltage reset. ★
