- The integrated LEDs indicate the following operating states.
- Position relay K2
- Position relay K3
- Position relay K4
- LED’s or signalling outputs signalise an opened protective device or emergency stops.
- Monitoring effected on both contact circuits of the sensor.
- Position relay K1
- Supply voltage UB
- When the safety guard or the emergency stop circuit is opened, a 24V signal is switched at each output concerned (Y1...Y4) and the assigned LED is lit.

notice - Wiring example
 
Start level: Depends on the wiring of the safety relay module.
Sensor level: 2-channel control of magnetic safety switches according to EN 60947-5-3
Output level: 2-channel control of a downstream safety relay module
The control recognises cross-short, cable break and earth leakages in the monitoring circuit.
If the inputs S1, S3, S5 and S7 are not used, they have to be bridged to +
If the inputs S2, S4, S6 and S8 are not used, they have to be bridged to -
The safety relay modules must be suitable for signal processing for single or dual-channel floating NC-contacts
Start and actuator configuration has to be effected in accordance with the data sheet
Output 23/24 is closed in de-energised condition.
The wiring diagram is shown with guard doors closed and in de-energised condition.
