1) Unplug from the mains.
2) Plug back into the mains.
3) Press the black button and then in addition the white
button and keep these pressed until the lamp starts
flashing 3x.
4) Release the buttons.
5) All the data has now been deleted.
In the ex factory state, the door data is deleted and the
operator can be immediately programmed

Note
Further signals from the operator lighting (flashes repeatedly
on inserting the mains plug) are explained in section 3.6.3.
3.3.2 Programming the operator
ATTENTION
Since during the learning/programming pro-
cedure the force cutoff is without function,
it is essential that the installer stays with
the equipment and exercises increased
vigilance.
Please also bear in mind that the learning proce-
dure automatically ends at the "CLOSE" position.
1) Plug into the mains. When the operator is plugged
into the mains for the very first time, the operator
lighting flashes one or three times. Check once again
whether the carriage on the door link has engaged
(see fig. 16). All the DIL switches 1 - 5 are at "ON".
2) Press the black button (for approx. 6 sec.) until the
lamp starts flashing. Allow to flash twice, then release
the "learn" button.
3) Now press the white operating button so that the
door can travel to its "OPEN" position. The door
moves as long as the white button stays pressed
(dead man's operation). Once the button is released,
the door stops immediately. The next time the button
is pressed, the door travels in the opposite direction.
This procedure is repeated until the desired "OPEN"
position is reached. When in its "OPEN" position, the
door must not be allowed to press against its mecha-
nical limit stop (rubber stopper). This could other-
wise give rise to an error message (4 flashing signals
and abrupt termination of the learning procedure). In
its "OPEN" position the door must maintain a mini-
mum distance of approx. 5 cm to its limit stop.
4) Briefly press the black "learn" button. Your operator
carries out the remaining settings automatically! The
door travels slowly to the "CLOSE" position. During
this cycle, the distance of travel is learned (lamp flashes
twice). The door then opens again twice and closes
again twice in order to learn the necessary current
values (lamp flashes three times).
5) On completing the 5 learning cycles, the door is at the
"CLOSE" position, the operator lighting switches off.
The operator is now programmed ready for
operation.

Note
If the force or speed is insufficient for the learning cycle,
the force/speed can be increased from 30 % to 50 % via
the DIL 4. Start the learning procedure once again.
For sectional doors, we recommend setting the DIL 4
to "OFF" before starting the learning phase.

3.3.3 Setting the maximum forces

The required forces for opening and closing the door,
see section which were learned and stored during the learning phase,
are updated also during the subsequent travel cycles.
That's why, if the running action of the door gets increa-
singly sluggish (e.g. spring tension slackens), it is impor-
tant for safety reasons that these values do not infinitely
reset themselves, as any necessary manual operation of
the door could otherwise present a possible safety risk
(e.g. door could crash to the floor).
It is for this reason that the maximum available force
for opening and closing has been finitely preset at
the factory (potentiometer set at medium), but this
can be increased if required. The maximum forces set at
the potentiometer have a slight effect on the sensitivity
of the force limit, since the forces actually needed
were stored during the learning procedure.
The force set at the factory is suitable for operating
standard doors.
For setting the maximum opening and closing forces, a
potentiometer, marked "P2 force", can be accessed by
opening the view panel (see fig. 19.1). In doing so, turning
clockwise increases the force, while turning anticlockwise
reduces the force.
Reducing the setting is only advisable if a light-moving
door is involved, a higher level of safety is desired and
"normal" operation is guaranteed (must be established
through testing).

3.3.4 Setting the running speed

If necessary, the running speed of the operator can be
altered. For setting the speed, a potentiometer, marked
"P1 speed", can be accessed by opening the view
panel (see fig. 19.2). In doing so, turning clockwise
increases the speed, while turning anticlockwise reduces
the speed. In the ex factory state the speed is set at
maximum (P1 RHH/right rotating).
Note
After altering the running speed, the operator must be
reprogrammed!
CAUTION: Danger
Setting the potentiometer too high can
result in serious injury!
ATTENTION
If the potentiometer is set too low, this will
put the operator out of action!
