9.3.  Functional check

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 persons in the danger zone.

 

Ì

Observe the valid accident prevention regulations.

9.3.1.  Electrical function test

After installation and any fault, the safety function must be fully checked. Proceed as follows:
1.  Switch on operating voltage.

 

¨

The machine must not start automatically.

 

¨

The safety switch carries out a self-test. The green STATE LED flashes for 5 s at 5 Hz. The green STATE LED then flashes 

at regular intervals.

2.  Close all guards.

 

¨

The machine must not start automatically. 

 

¨

The green STATE LED illuminates continuously.

3.  Enable operation in the control system.
4.  Open the guard.

 

Ì

The machine must switch off and it must not be possible to start it as long as the guard is open.

 

Ì

The green STATE LED flashes at regular intervals.

Repeat steps 2 - 4 for each guard.
