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.

Before carrying out the functional check, make sure that there are no per-
sons in the danger area.
Observe the valid accident prevention regulations.

Switch on operating voltage.

The safety switch carries out a self-test.  

The green STATE LED flashes for 3 s with 10 Hz. 

The STATE LED then flashes at regular intervals.

Close all safety guards.

The machine must not start automatically.
The green STATE LED illuminates continuously.

Enable operation in the control system.
Open the safety guard.

The machine must switch off and it must not be possible to start it as long as 

the safety guard is open.
The green LED STATE flashes at regular intervals.

Repeat steps -4 for each safety guard.
