3.2.8 MANUAL FUNCTION TEST
After assembly of the garage door drive ensure with 2 - 3 ma-
nually actuated opening and closing processes that the func-
tion of the door was not impaired by the assembly (see also 3.1.1
Check condition of the door): Actuate the emergency release
system in the garage and move the door by hand. The pulley
engages for every movement over the drive dog and is respec-
tively released through further actuation of the emergency re-
lease system.
3.2.9 ATTACHING THE WARNING SIGNS
Permanently fix the warning label which refers to danger of get-
ting caught in the door and to regular checking of the obstacle
detection on a clearly visible place or near firmly fixed on moun-
ted control elements.
Fix the warning label which refers to operation of the emergen-
cy release system on a clearly visible place or near the emer-
gency unlocking system.
Permanently fix the warning label which refers to the fact that
children should not be in the area of the opened door on a clear-
ly visible place near the swivel area of the door.
3.2.10 ADAPTING THE RAIL LENGTH
In tight installation situations the rail can be shortened in order
to reduce the total length of the drive. Here the maximum path
traversed by the device (= the maximum door height!) also redu-
ces by the amount reduced.
- Only perform the shortening on the front end of the rails.
- In the case of split rails the side with the dead stop for the
cap rails (see Figure 6) must not be shortened.
- The shortened part of the rail must have a minimum length
of 500 mm.
- Perform the shortening using a suitable metal saw blade on
an electrical saw with guide.
- Shorten the lengths of the chain and the toothed belt
appropriately: the amount of the reduction in length of
the rail x2 (for example: shortening of the rail by 250 mm
requires a shortening of the chain or toothed belt by
500 mm).
Unpack the rail and pull the chain / toothed belt with deflection,
head mount and carriage out of the rail. Shorten rail and deburr.
Unlock the carriage (see Figure 12) and pull the carriage from
the drive dog.
Toothed belt version:
Remove the securing screw (1) using a Phillips screwdriver (a)
and pull out the belt connector jacket (2) (b); take the toothed
belt out of the belt drive dog (3) (c).
Shorten the toothed belt using a side cutter to achieve the re-
quired length.
Insert the toothed belt according to the preformed mount with
6 teeth into the belt drive dog.
Push on the belt connector jacket and fix in place with the se-
curing screw.
The securing sleeve must sit exactly: Toothed belts as well as
parts of the drive dog must not be lubricated to simplify the
work process!
Mount the rail as described from Picture 7.
