9.1. Teaching-in a new CKS key
Teach-in of CKS keys can be repeated any number of times. Observe the teach-in operation in accordance with section
9.1.2. Teach-in operation on the CES evaluation unit for this purpose. Faulty CKS keys can thus be replaced at any time. In
the delivery state, the keys in the evaluation unit have already been taught-in.

9.1.2. Teach-in operation on the CES evaluation unit
A new CKS key can be taught-in on the CES evaluation unit if necessary.
During the teach-in operation the safety outputs are open. The system is in the safe state.
Important!
Ì
CKS keys must not be removed during the teach-in operation.
Ì
If the teach-in operation is interrupted, the CES evaluation unit switches to the safe fault state
(diagnostic LED illuminates) and signals this operating fault with the STATE LED by 3 short flashes
that are repeated every 1 second. The teach-in operation must be repeated.
Ì
The number of teach-in operations is unlimited. The CES evaluation unit can be re-configured as
often as required.
Ì
CKS key adapters cannot be interchanged without a renewed teach-in operation.
Ì
If a CKS key is not taught-in, it is not recognized by the respective CKS key adapter.
Ì
Even if only one new CKS key needs to be taught-in, a complete new teach-in operation must be
carried out.
Ì
Do not change DIP switches during operation.
