6. Function
The key adapter CKS can, e.g., be used as a lockout mechanism. As soon as the key is in the key adapter, this is reported
via the AS-Interface bus. Each delivered key possesses a unique electronic coding and so is a unique element in the system
used.
The code of a key cannot be reprogrammed.
If a permissible code is detected, a bit sequence is sent via the AS-Interface bus to signal that the key is inserted.
The zero sequence is sent via the AS-Interface bus when the key is removed from the key adapter. The machine cannot be
started.
If there is a fault in the key adapter, the zero sequence is sent and the LED illuminates.
6.1. Switching states
The detailed switching states for your key adapter can be found in the system status table. All indicator LEDs are described
there.

9.2. Teach-in function for key
The key must be allocated to the key adapter using a teach-in function before the system forms a functional unit.
The zero sequence is sent during the teach-in operation.
Important!
Ì The teach-in operation may be performed only if the device functions awlessly. The red LED must
not be illuminated.
Ì The key adapter disables the code of the previous key if teach-in is carried out for a new key.
Teach-in is not possible again immediately for this actuator if a new teach-in operation is carried
out. The disabled code is released again in the key adapter only after a third code has been
taught-in.
Ì The key adapter can only be operated with the last key taught-in.
Ì If the key adapter detects the key that was most recently taught-in when in the teach-in standby
state, this state is ended immediately and the key adapter changes to normal operation.
Ì If the key to be taught-in is within the operating distance for less than 60s, it will not be activated
and the most recently taught-in key will remain saved.
9.2.1. Preparing device for teach-in operation and teaching-in key
1. Insert new key
2. Connect AS-Interface bus to the key adapter.
¨ Teach-in operation starts, the LED ashes green (approx. 1 Hz). During the teach-in operation, the key adapter checks
whether the key is a disabled key. 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 key code from the teach-in operation in the key adapter, the key adapter must then be disconnected
from the AS-Interface bus for min. 3seconds.
