Light chain (LK)
Connection of the chain ends and operation
Connection of the chain ends
Before connecting the ends of the chain using the chain lock provided, it must be en‐
sured that the chain is not twisted when it is mounted.
The chain lock must be fastened carefully.
Operation
Note! In order to prevent repeated coupling and decoupling of the emergency
manual operation mechanism, the chain must be kept taut during operation.
The door can be opened and closed manually by pulling the respective side of the
chain vertically. In order to prevent electrical operation of the door system during
emergency manual operation, the safety switch S3F is activated when the chain is
pulled. After operation, ensure that the chain hangs "freely" again so that the safety
switch SF3 is released and electrical operation is enabled once more.
