Commissioning
7.1
Teach-in
7.1.1
Teaching in the first actuator
Overview
An actuator must be taught-in during commissioning. Only the most recently taught-in
actuator is valid.
During a teach-in operation, the OSSDs are in the OFF state, i.e. the system is in a safe
state.
Important information
NOTE
In the delivery state, there is a time window of 30 minutes for teach-in after the device
is switched on. The safety locking device then switches to the safe state. For a new time
window, the device must be restarted (disconnect voltage supply and redo).
NOTE
The teach-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 36
). The
teach-in operation must then be repeated after restarting the device.
NOTE
The taught-in actuator must be documented.
Prerequisites
•
Device variant is not universally coded. Universally coded devices do not require a
teach-in.
Approach
1.
Open movable physical guard.
2.
Connect safety switch to voltage supply (
see "Electrical installation", page 25
).
✓
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 movable physical guard.
✓
When the movable physical guard is closed and the actuator has reached the
required position, the safety switch automatically starts the teach-in sequence
after 3 seconds. The individual steps are indicated via the LEDs.
