7 Commissioning
7.1 Safety
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
1. Before commissioning the machine, have it checked and released by qualified
safety personnel.
2. Make sure that the time for the safety requirement (closing the protective device
again) is longer than the response time.
7.2 Switching on
The device initializes after switching on. During this process, the OSSDs are switched
off and the light emitting diodes light up alternately in the color sequence green, red,
and yellow. For unique coded and permanently coded safety switches only: If any actua‐
tors have already been taught in, the STATE light emitting diode will flash once after ini‐
tialization for each taught-in actuator.
7.3 Teach-in
DANGER
Bypassing the protective device
The dangerous state may not be stopped in the event of non-compliance.
b
Document teaching-in of an actuator.
b
During regular thorough checks, make sure that the taught-in actuator is still being
used.
Variant for universally coded actuators
No teach-in is required.
Variant for unique coded actuators
An actuator must be taught in during commissioning. Up to 8 actuators may be taught
in one after the other. Only the most recently taught-in actuator is valid. Previously
taught-in actuators cannot be taught in again.
Variant for permanently coded actuators
An actuator must be taught in during commissioning. It is not possible to teach in any
further actuators.
Teaching in an actuator
1. Open the physical guard.
2. Connect the safety switch to the voltage supply ( see "Electrical installation",
page 23 ).
✓
The start sequence is performed. The LEDs light up alternately in the color
sequence green, red, and yellow.
3. Close the physical guard.
✓
When the guard is closed and the actuator has reached the appropriate position,
the safety switch will automatically start the teach-in sequence. The LEDs will dis‐
