Initial setup
1. Apply operating voltage to the safety switch.
¨
The green LED flashes quickly (approx. 5 Hz).
A self-test is performed during this time (8 s). After this, the green LED flash-
es 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 quickly, the actuator is in the limit range. 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 STATE LED flashes for 8 s with 5 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
