5.
No later than 5 minutes after successfully teaching in the actuator, disconnect and
restore the voltage supply to the safety switch. Otherwise, the device changes to
the safe state. The previous actuator remains valid.
✓
When the taught-in actuator is in the response range, both OSSDs switch to the ON
state and the STATE LED lights up green.

7.2
Thorough check during commissioning and modifications
DANGER
Hazard due to unexpected starting of the machine
Death or severe injury
b
Before carrying out the functional test, make sure that there are no people in the
hazardous area.
Approach
Check that the device is functioning properly after installation and after every fault. To
do this, proceed as follows:
Mechanical function check-out
b
Open the movable physical guard and close it again. The components of the
safety locking device must not collide with other parts. When the movable physical
guard is closed, the actuator must be in a position which enables the lock to be
actuated.
Electrical function check-out
1.
Switch on the supply voltage.
2.
Close all movable physical guards and activate the locking function. The machine
must not start up on its own.
3.
Check the lock. It must not be possible to open the movable physical guard.
4.
Start the machine function.
5.
For variants with locking monitoring (protection of people): Ensure that the locking
function cannot be unlocked as long as the dangerous machine function is active.
6.
Stop the machine function and deactivate the lock.
7.
Check whether the movable physical guard is kept locked until there is no more
risk of injury (e.g., due to run-on movements).
8.
For variants with locking monitoring only (protection of people): check the restart
interlock. It must not be possible to start the machine function as long as the
locking function is unlocked.
9.
For variants with escape release: Check the function of the escape release.
10. Repeat steps
to
for each individual safety locking device.
