Initial setup
1. Apply operating voltage to the safety switch.
¨ The green LED flashes quickly (approx. 10 Hz).
A self-test is performed during this time (approx. 8 s). 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 at approx. 2 Hz, the actuator is in the boundary area.
In this case the safety guard must be re-adjusted such that the actuator is com-
pletely 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-
sons in the danger area.
Ì Observe the valid accident prevention regulations.
1. Switch on operating voltage.
Ì The safety switch carries out a self-test.
The green LED STATE flashes for 8 s with 10 Hz.
The STATE LED then flashes at regular intervals.
2. Close all safety guards.
Ì The machine must not start automatically.
Ì The green STATE LED illuminates continuously.
3. Enable operation in the control system.
4. Open the safety guard.
Ì The machine must switch off and it must not be possible to start it as long as
the safety guard is open.
Ì The green LED STATE flashes at regular intervals.
Repeat steps 2-4 for each safety guard.
