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

 ¨ The  green  LED  illuminates  continuou sly  and  i ndicates  the  detec tion  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.
