Check that the device is functioning properly after installation and after every fault. To
do this, proceed as follows:
Mechanical functional test
b
Open the protective device and close it again. The components of the safety lock‐
ing device must not collide with other parts. When the protective device is closed,
the actuator must be in a position which enables the lock to be actuated.
Electrical functional test
1.

Check the restart interlock. The machine function must not start while the lock is
deactivated.
9.
Repeat steps 3 to 8 individually for each protective device.
