Emergency control
Danger!
(only synchronous group)
BSY+ synchronous control regulates and monitors the difference in position between the drives
(max. 30 mm). In the event of an error, all drives are stopped. Before the decision is made to run the
drives in auxiliary mode, the cabling should be checked. A short circuit, a reversed phase sequence
or an interruption of the bus line will cause the drives to stop or not start up.
When running the drives in auxiliary mode, only the drive in the synchronous group to which the
magnet is held is driven. The running direction is determined by the activation direction.
Strain on glass can cause the glass to break.
Cordon off the danger area.
Take personal safety precautions.
A second person must be able to interrupt the drive voltage at any time.
If repeat zeroing of a drive is necessary for installation reasons (chain is driven out >
23 mm in closed position) or for servicing:
Travel the drive to closed position. Wait until the drive has driven completely closed.
Perform zeroing on the drive using the MAG 502 magnet. The magnet gives the drive a
second CLOSE command and performs zeroing in the event of an overload cut-off. This
is confirmed by the drive quietly humming. Each drive of the set must be individually
zeroed in a synchronous group.
