Setup (only version Multicode)
1. Apply operating voltage to the device.
¨ The green LED flashes briefly and a self-test is performed.
After this, the LED flashes cyclically one time and signals that it is in standby
state.
2. Move actuator to the read head (observe distance < S
ao
).
¨ The green LED illuminates continuously and indicates the detection of the
actuator.
If the green LED is flashing in fast flashing sequences, the actuator is in the limit
range. In this case the safety guard must be re-adjusted such that the actuator is
completely in the read area.
Functional check
After installation and any fault, the safety function must be fully checked. Proceed
as follows:
Warning!
Danger of fatal injury as a result of faults in installation and functional check.
Ì Before carrying out the functional check, make sure that there are no per-

1. Switch on operating voltage.
Ì The STATE LED then flashes at regular intervals.
2. Close all safety guards.
Ì The machine must not start automatically.
