10.2. Teach-in function for actuator (only for unicode evaluation)
The actuator must be allocated to the safety switch using a teach-in function before the system forms a functional unit.
During a teach-in operation, the safety outputs and the monitoring output OUT are switched off, i.e. the system is in the
safe state.
Tip!
It is recommended to perform the teach-in operation prior to mounting. Mark switches and actuators
that belong together in order to avoid confusion. For devices to be connected in series, we recommend
performing the teach-in operation separately for each device prior to series connection.
Important!
Ì
The teach-in operation may be performed only if the device functions flawlessly. The red DIA LED
must not be illuminated.
Ì
The safety switch disables the code of the preceding device if teach-in is carried out for a new
actuator. Teach-in is not possible again immediately for this device if a new teach-in operation is
carried out. The disabled code is released again in the safety switch only after a third code has
been taught-in.
Ì
The safety switch can be operated only with the last actuator taught-in.
Ì
The number of teach-in operations is unlimited.
Ì
If the switch detects the actuator that was most recently taught-in when in the teach-in standby
state, this state is ended immediately and the switch changes to normal operation.
Ì
If the actuator to be taught-in is within the actuating range for less than 60 s, it will not be activat-
ed and the most recently taught-in actuator will remain saved.
Ì
After an unsuccessful teach-in operation, the switch changes to normal operation.
10.2.1. Preparing device for the teach-in operation and teaching-in actuator
1. Apply operating voltage to the safety switch.
¨
The green LED flashes quickly (approx. 10 Hz).
A self-test is performed during this time (approx. 10 s). After this, the LED flashes cyclically three times and signals
that it is in standby state for teach-in.
Standby state for teach-in remains active for approx. 3 minutes.
2. Move new actuator to the read head (observe distance < S
ao
).
¨
Teach-in operation starts, green LED flashes (approx. 1 Hz). During the teach-in operation, the safety switch checks
whether the actuator is a disabled actuator. Provided this is not the case, the teach-in operation is completed after
approx. 60 seconds, and the green LED goes out. The new code has now been stored, and the old code is disabled.
3. To activate the new actuator code from the teach-in operation in the safety switch, the operating voltage to the safety
switch must then be switched off for min. 3 seconds.
