7.1 Teach-in
7.1.1 Teaching in the first actuator
Important information
NOTE
Safe
ty locking devices in the delivery condition have a teach-in-window of 30 minutes
after being switched on. After this, the Safety locking device switches into safe state.
For a new teach-in-window the device needs to be restarted (disconnect and restore the
voltage supply).
NOTE
The te
ach-in process is invalid if canceled, e.g. by interruption of the voltage supply or
premature removal of the actuator.
The safety locking device then goes into the safe state, and the LEDs indicate the cause
of the invalid teach-in process (see "Fault indications during operation", page 32). You
can start a new teach-in process after a restrart of the device.
Prerequisites
•
D
e
v
ice variant is not universally coded. Universally coded devices do not require a
teach-in.
Approach
1. Open phy
sical guard.
2. Connect safety switch to voltage supply (see "Electrical installation", page 20).
✓
The start sequence is executed. All LEDs flash with alternating colors. OSSDs are
switched off in the meantime.
✓
The following indicators signal that the safety switch is ready for the teach-in
sequence.

3. Close physical guard.
✓
When the pr
otective device is closed and the actuator has reached the required
position, the safety switch automatically starts the teach-in sequence after 3 sec‐
onds. The individual steps are indicated via the LEDs.

res
tore the voltage supply to the safety switch. Otherwise the device will go into
safe state.
✓
The safety locking device is ready for use.
