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.
● ○ ○ ○ ○ 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

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.

Use the function test to test the safety function.
To do this, request the safety function once via the basic device
by pressing the emergency stop button, for example.
Check whether the safety function is executed correctly by then
switching the basic device and thereby also the contact exten-
sion on again.
