Safety reversal
To check the safety reversal:
1 .
Stop the door with both hands
while it is
closing
.
The door system must stop and
initiate the safety reversal.
2 .
Stop the door with both hands
while it is
opening
.
The door system must switch off.
3 .
Position a test object with a height
of approx. 50 mm in the centre of
the opening and close the door.
The door system must stop and
initiate the safety reversal as soon
as it reaches the obstacle.
▶
In the event of a failure of the safety reversal, a specialist
must be commissioned immediately for the inspection
and repair work.
6 .3
Normal operation
In normal operation, the garage door operator works
exclusively according to the impulse sequence control. It
does not matter whether an external button, a hand
transmitter button or the
T
button on the operator cover has
been actuated:
1st impulse:
The door runs towards an end-of-travel
position.
2nd impulse:
The door stops.
3rd impulse:
The door runs in the opposite direction.
4th impulse:
The door stops.
5th impulse:
The door runs in the direction of the end-of-
travel position selected in the 1st impulse.
etc.
The operator light will light up during a door run and go out
after approx. 2 minutes.

Behaviour during a power failure
In order to open or close the garage door by hand during a
power failure, the slide carriage must be disengaged from the
carriage coupling.
▶
See section 6.2.1 and 6.2.2
6 .5
Behaviour following a power failure
After the power returns, the slide carriage must be
re-engaged in the carriage coupling.
1 .
Move the carriage coupling close to the slide carriage.
2 .
Push down the green coupling slider.
3 .
Move the door by hand until the slide carriage snaps into
the carriage coupling.
4 .
Check whether the door completely reaches its open and
closed positions by conducting multiple uninterrupted
door runs.
Now, the operator is ready for normal operation again.
For safety reasons, the door will always open upon the first
impulse command after a power failure
during
a door run.
NOTE:
If the behaviour does not correspond to that described in
step
4
, even after multiple uninterrupted door runs, a new
learning run is necessary. First the existing door data must be
deleted (see section 9 and 4.2).

Inspection and Maintenance
The garage door operator is maintenance-free.
In the interest of your own safety, we recommend having the
door system inspected and maintained by a qualified person
in accordance with the manufacturer's specifications.
WARNING
Danger of injury due to unexpected door travel
Unexpected door travel can result during inspection and
maintenance work if the door system is inadvertently
actuated by other persons.
▶
Pull out the mains plug
and
, if applicable, the plug of
the emergency battery when performing all work on the
door system.
▶
Safeguard the door system against being switched on
again without authorization.
An inspection or necessary repairs may only be carried out by
a qualified person. Contact your supplier for this purpose.
A visual inspection may be carried out by the operator.
▶
Check all safety and protective functions
monthly .
▶
Malfunctions and / or defects at hand must be rectified
immediately
.
7 .1
Checking the tension of the toothed belt
▶
Check the tension of the toothed belt every
six months
and adjust if necessary (See figure
7 .4
).
During the start-up and slow-down phase, it is possible that
the belt will briefly hang out of the boom profile. However, this
does not result in any technical consequences and does not
negatively affect the function and service life of the operator.
7 .2
Checking safety reversal / reversing
To check safety reversal / reversing:
1 .
Stop the door with both hands
while it is
closing
.
The door system must stop and
initiate the safety reversal.
2 .
Stop the door with both hands
while it is
opening
.
The door system must switch off.
3 .
Position a test object with a height
of approx. 50 mm in the centre of
the opening and close the door.
The door system must stop and
initiate the safety reversal as soon
as it reaches the obstacle.
▶
In the event of a failure of the safety reversal, a specialist
must be commissioned immediately for the inspection
and repair work.
