5 Special functions and any other adjustment
possibilities of the garage door operator
5.1 Second opening position (airing position)
In the airing position a second opening position can be
freely programmed. The latter is switched by
channel 2
of
the radio receiver. Terminal 20 (0 V) and 23 (impulse input
partial opening). Set DIP switch 7 (SCH2) to OFF .
5.1.1 Programming the second opening position (airing
position)
The operator is ready for use and the operator stands still.
Check again if the the guiding hitch is clutched in the
flange lock / belt lock (see figure 17 ).
1) Press the black button (for approx. 6 sec.) until the
lamp starts flashing. Allow to flash twice , then press
additionally the white button and press (for approx. 2
sec.) until the lamp quickly flashes twice . Then
release both buttons.
2) Now press the white operating button so that the
door can travel to its "Second opening" position. The
door moves as long as the white button stays pressed
(permanent contact). 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 "Second
opening" position is reached.
3) Briefly press the black “learn” button. The operator
lighting is switched on.
“Second opening position”
is
now programmed.
5.2 Defined direction instructions
A defined direction option is adjustable through DIP switch
7 (SCH2) .
1) radio channel 1 (terminal 20/21 ) = open – stop – open
etc.
2) radio channel 2 (terminal 20/23 ) = closed – stop –
closed etc.
3) Set DIP switch 7 (SCH2 ) to ON
5.3 Quick-opening function
The quick-opening function is selectable through DIP
switch 3 (SCH2 ). Thereby: up to 50 % higher opening
speed*.
1) Set DIP 3 (SCH2 ) to ON = quick-opening speed
2) Set DIP
3 (SCH2
) to
OFF
= normal opening speed
* depending on the door
Note
The motor of the garage door operator is equipped with a
thermal overload protection. In case of 2-3 quick door runs in
“OPEN” position (max 40 sec.) within 2 minutes, this overload
protection reduces the door speed, i.e. the door travels in
direction “OPEN” and “CLOSED” have the usual speed. After a
rest period of 2 additional minutes, the next run in direction
“OPEN” is executed quickly.
ATTENTION: danger to life
This function is not to be selected for
tipping and swing doors, but only for
holohedrally closed sectional doors!
* Accessory, is not included in delivery!
Note
After changing the door speed the operator has to be newly
programmed!
5.4 Soft-stop
Soft-start is adjustable with DIP switch 4 (SCH2) before
reaching end-of-travel position
“CLOSED”
1) Set DIP 4 (SCH2) to ON = 30 % soft-stop – up and
over door
2) Set DIP 4 (SCH2) to OFF = 50 % soft-travel speed
5.5 Short return to the position “door closed”
The short return to the position “door closed” is
adjustable with DIP switch 5 (SCH2) , i.e. the slide moves
briefly to position “OPEN” when reaching “CLOSED” .
1) Set DIP 5 (SCH2) to ON = short return “long”
2) Set DIP 5 (SCH2) to OFF = short return “very short”
Note
If DIP5 is activated during the memorising process, the
following functions are activated:
1) DIP5 (SCH2) set to ON = Short return “very short”
2) DIP5 (SCH2) set to OFF = Short reverse deactivated
On each new memorising process this procedure has to be
repeated.
5.6 Automatic timer
With this function, the door is automatically closed after
a preset open phase has elapsed. According to EN 12453
Tab.1, this function is only permitted if combined with a
photocell.
Note
If the "automatic timer" is set, impulse operation is not
possible. Each command causes the door to open or
the open phase to be reset.
A closing from the position “partial opening” occurs only if the
distance to the end-of-travel position “door CLOSED” is
> 500 mm. In case of a smaller distance, the door has to be
closed by reoperating the button “partial opening”.
5.6.1 Programming the automatic timer / early warning
phase
The door must be at a standstill and ready for operation.
Briefly press the black "learn" button (lamp flashes five
times), wait till the desired open phase is over (min.
10 sec. to max. 150 sec.). Then briefly press the black
"learn" button, the lamp continues to flash five times. You
must now wait for the early warning phase to be set (min.
3 sec. to max. 30 sec.), then briefly press the black "learn"
button again. You have now activated the automatic timer.
In this mode the door can only be opened via radio and
button. If a command is given during the closing phase,
the door reverses and travels to its "OPEN" position.
Automatic closing only takes place from the "OPEN"
position provided no safety circuit has been broken and
the open phase has elapsed.
Note
If, on account of the overcurrent cutoff, the door has
reversed twice to its "OPEN" end-of-travel position, the
automatic timer will be blocked. The garage lighting signals
the impulse code for "twice safety device" and an
acknowledgement
via the button must be issued. The open phase
will not start running until this acknowledgement has been
issued.
