Emergency manual operation
Emergency manual operation is only intended for commissioning the drive, maintenance work and emergency operation in order
to open or close the door in the event of a short-term power failure. Emergency manual operation is solely intended for manual
operation.
Caution
Before emergency manual operation is used, the door system must be safely disconnected from the power
supply. Emergency manual operation (HK) is only allowed with the motor turned off, via hand crank, and can
only be carried out by the service technician or instructed personnel. Emergency manual operation (LK) is also
only allowed with the motor turned off.
Attention
Emergency manual operation is not intended for long-term use (e.g., from commissioning of the drive to con‐
tinuous power supply).
Doors with counterweights must be set in such a way that they are fully counterweighted in all positions. If the
door is not counterweighted properly, the manual force required is increased and the service life of the emer‐
gency manual operation mechanism is reduced.
Note
(applies to cam-operated limit switching)
The door must not be moved beyond the limit positions as otherwise a safety limit switch (S1F/S2F) is activa‐
ted. If activated, electrical operation of the door system is only possible when the safety limit switch (S1F/
S2F) is “released” via emergency manual operation.
2 different systems are available for emergency manual operation:
▪
Crank handle (HK)
▪
Light chain (LK)
Note
For each type of emergency manual override system, an appropriate notice (as per EN60335-2-103) must be
permanently placed in the vicinity of the corresponding operating element describing how it is to be used.
Stickers for use as notices which are appropriate to the drive are included within the scope of delivery.

Operation
Remove the cover by turning it anticlockwise (1.) first, and then lifting it off (2.).
For emergency manual operation, the crank handle is inserted in the motor shaft.
The crank handle must firstly be snapped onto the motor shaft by applying slight
pressure (3.) and turning carefully (4.). Following this, proper emergency manual op‐
eration with the crank handle is possible.
The door can then be opened or closed with the crank handle by turning whilst apply‐
ing slight pressure.
In order to prevent electrical operation of the door system during emergency manual
operation, the safety switch S3F is opened upon insertion of the crank handle.
Attention! Following operation, the crank handle must be completely removed
once more to allow electrical operation of the door system to resume. Once the
crank handle has been removed, the cover must be refitted in a clockwise direc‐
tion in order to maintain the drive's degree of protection. Make sure that it clicks
audibly into place.
