4.
To code the safety locking device permanently during the last teach-in sequence –
“programming complete” – open the protective device. The DIAG light emitting
diodes light up red. Close the protective device again. STATUS light emitting diodes
flash green (1 Hz). The entire process must be completed within the teach-in
sequence “programming completed”, which lasts 15 seconds. After this point, per‐
manent coding with this actuator is no longer possible.
✓
The teach-in process is complete. When the locking command is active, the lock is
now activated. Previously taught-in actuators can no longer be used or taught in
again. Other actuators can be taught in in the same way.

Testing
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.
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.
Switch on the supply voltage.
2.
Close all protective devices and activate the locks. The machine must not start up
on its own.
3.
Check the lock. It must not be possible to open the protective device.
4.
Start the machine function.
5.
Make sure that the lock cannot be deactivated as long as the dangerous machine
function is active.
6.
Stop the machine function and deactivate the lock.
7.
Check whether the protective device is kept locked until there is no more risk of
injury (e.g., due to run-on movements).
8.
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.
NOTE
In the case of the “power to lock” version, an active locking command can be simulated
by applying a 24 V DC voltage at the “lock input” contact.
