9. Setup
9.1. LED displays
You will find a detailed description of the signal functions in chapter 10. System status table on page 13 .
LED Color
STATE green
DIA red
9.2. 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 bit sequence 0000 is transmitted, i.e. the system is in the safe state.
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 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.
9.2.1. Preparing device for the teach-in operation and teaching-in actuator
1. Connect AS-Interface bus to the safety switch.
¨
A self-test is performed for approx. 0.5 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 safety switch must then be dis-
connected from the AS-Interface bus for min. 3 seconds.
