Operation

Note

In order to prevent repeated coupling and decoupling of the

emergency manual operation mechanism, the chain is to be

kept tense 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. Following operation it must ensured that the chain hangs

"freely" so that the safety switch SF3 is released and, thus, electrical opera-

tion is possible.
