Installation Instructions

2.1

Required clearance for installing the operator

When installing the operator, the clearance between the
highest point of the door on opening and the ceiling must
be at least 30 mm (see fig. 1.1a / 1.1b).
2.2 The mechanical door latches on an up-and-over
door must be immobilized (see figure 1a). In the case
of door models not listed here, the catches must be
locked on site.
2.3 On a sectional door the internal mechanical latch must
be completely dismantled (see figure 1b).
ATTENTION
When installing the operator, the pull cord
must be removed.
(see figure 1.2b)
2.4 Note
Up-and-over doors with a forged iron door handle
Divergent from the illustrated section (see fig. 2a / 3.2a),
these doors require the lintel bracket attachment and
the door link bracket to be affixed off-centre.
2.5 Centrally positioned lock on a sectional door
For sectional doors with a centrally positioned lock, affix
the lintel bracket attachment and the door link bracket
off-centre (see fig. 2b).
2.6

Off-centred reinforcement profile on a sectional door

In the case of an off-centred reinforcement profile on a
sectional door, fix the door link bracket to the nearest
reinforcement profile on the left or right (see fig. 2b).
2.7

Tensioning the drive medium

The toothed belt or chain of the operator boom has been
pretensioned at the factory for optimum performance.
During the starting and braking phases of larger doors it
can happen that the belt or chain hangs out of the boom
profile temporarily. However, this does not pose a tech-
nical disadvantage nor does it have any negative effect
on the operator's function and service life.
CAUTION
Do not insert fingers into the boom while
the door is moving

3.1 Establishing the "CLOSE" end-of-travel position by
installing the limit stop
1) Insert the limit stop for the CLOSE end-of-travel loosely
into the boom between the carriage and the door
(see fig. 4) and push the door by hand into the CLOSE
end-of-travel position

2) Then fix the limit stop for the OPEN end-of-travel
position (see fig. 7).
Note
If you are unable to push the door manually into the desired
OPEN or CLOSE end-of-travel positions, this indicates that
the door mechanics are too sluggish to be used with the
garage door operator and must therefore be checked (see
section 1.1.2)!
3.2

Notes on work involving electrics/electronics

ATTENTION
The following points apply to all work
involving electrics/electronics:
- Electrical connections may only be made by a
qualified electrician!
- On-site electrical installation must comply with
the relevant safety regulations (230/240 V AC,
50/60 Hz)!
- Before working on the operator, always unplug
from the mains!
- External voltage at any of the controls connec-
ting terminals will completely destroy the elec-
tronics!
- To avoid malfunctions, ensure that the control
cables of the operator (24 V DC) are laid in an
installation system separate to other supply lines
(230 V AC)!
3.3

Putting the operator into service

The operator features a memory (fail-safe even in the
event of a power failure) where the door-specific data
(distance of travel, forces necessary for moving the door
etc.) acquired during the learning procedure are stored
and updated during subsequent travel cycles. This data
is only applicable to this particular door. If another door
is to be used or if the running behaviour of the door has
greatly changed (e.g. on subsequent adjustment of the
limit stop or fitting of new springs etc.), the data must
be deleted and the operator reprogrammed.
ATTENTION
Initial operation must be carried out by
a specialist. Putting into service must be
recorded in writing. The operator is just one
constituent part of the overall door system.
The company responsible for the overall
door system issues the Declaration of
Conformity and attaches the CE Mark of
Conformity. Attaching the CE Mark of
Conformity to the door and issuing the EC
Declaration of Conformity documents con-
formity with the EC Machines Directive.
3.3.1 Deleting the door data (see figure 16)
If despite several attempts, you are not successful in
completing the learning procedure, we recommend that
the read-in data be reset. The read-in data can be dele-
ted as follows:
