ENGLISH
The function of the mechanical release should be checked
every month. The pull cord with knob may only be actu-
ated when the door is closed, otherwise in the case of
weak, broken or defective springs or due to a deficient /
faulty counterbalance, there is a risk that the door could
close extremely quickly.
ATTENTION
Never hang bodily from the pull cord!
All persons using the door system must
be shown how to operate the garage door
opener properly and safely. Demonstrate
and test the mechanical release as well
as the safety return. To do this, halt the
closing door by grasping it with both
hands. The door system should gently
cut-out and initiate the safety return.
The same should happen during the
opening cycle, i.e. the door system
gently cuts out and the door comes to
a halt.
3.6.1 Normal operation
During normal operation the garage door operator works
exclusively on impulse sequence, whereby it makes no dif-
ference whether the external button, a programmed hand
transmitter button or the transparent button was pressed:
1st Impulse: Operator causes door to move towards
an end-of-travel position.
2nd Impulse: Operator causes door to stop.
3rd Impulse: Operator causes door to travel in the
opposite direction.
4th Impulse: Operator causes door to stop.
5th Impulse: Operator causes door to travel in the
direction of the end-of-travel position
selected when the first impulse was
generated
etc.
The operator lighting comes on when the door moves
and automatically goes out 3 minutes later on completion
of the cycle.
3.6.2 Operation following actuation of the mechanical
release
If, for instance due to a power failure, the mechanical
release was actuated, the carriage must be re- engaged
in the belt lock before normal operation can be resumed:
1) Move the operator until the belt lock in the boom is well
accessible for the carriage, and then stop the operator.
2) Press the green button on the carriage (see figure 19).
3) Move the door by hand until the carriage re- engages
in the belt lock.
4) Carry out several uninterrupted travel cycles to check
whether the door has fully reached its closed position
and whether it has also fully opened (the carriage comes
to a halt shortly before the OPEN limit stop).
The operator is now ready to resume normal
operation.
Note
If, after carrying out several uninterrupted travel cycles, the
behaviour/action does not correspond to that described
in stage 4, a new learn operation will be necessary (see
section 3.3.2).
3.6.3 Signals from the operator lighting
If the mains plug is inserted without the transparent
button (with operator cover removed the circuit board
button) being pressed, the operator lighting flashes two,
three or four times.
Flashing twice
indicates that no door data is stored or has been deleted
(as in the ex factory state): programming can then be
carried out immediately.
Flashing three times
indicates that door data is stored but that the last door
position is not sufficiently well known. The next travel
cycle is therefore an OPEN reference cycle. This is then
followed by "normal" travel cycles.
Flashing four times
indicates that not only is door data stored but also that
the last door position is sufficiently well known, so that
"normal" travel cycles taking into consideration the im-
pulse sequence (OPEN-STOP-CLOSE-STOP etc.) can
follow (normal behaviour following successfully comple-
ted programming and a power failure). For safety rea-
sons, whenever there is a power failure during a travel
cycle, i.e. when the door is still in motion, the first impulse
command always results in the door opening.
Note
An OPEN reference cycle can be enforced if, when the
mains plug is inserted, the external button (connected
at terminals 20 and 21a) is pressed. In this case, the ope-
rator lighting flashes three times.
Replacement lamp for operator lighting:
24 V/10 W, socket: B(a)15s
3.6.4 Error messages / diagnostic LED
(light emitting diode, see figure 10.1)
When operation does not go to plan, a diagnostic LED
(visible through the transparent button even with the
operator cover in place), helps you to easily identify the
possible causes. In the programmed state this LED nor-
mally glows constantly and goes out as long as an ex-
ternally connected IMPULSE device is activated (see
section 3.5.2).
Note
On the basis of the behaviour explained above, a short-
circuit in the connecting lead of the external button or a
short-circuit in the button itself can be recognised even if
normal operation of the garage door operator with the re-
mote control or the transparent button is otherwise possible.
