3.5.2 Connecting external IMPULSE buttons to start or
stop door travel cycles
One or several buttons with closer contacts (floating),
such as internal buttons or key switches, is/are con-
nected (then parallel) as follows (see fig. 11):
1) first contact to terminal 21a (impulse input).
2) second contact to terminal 20 (0 V).
3.5.3 Connecting a cutout switch or a wicket door con-
tact (must feature forced opening) to stop and/or
cut off the operator (STOP or emergency-OFF
circuit)
A cutout switch with opener contact (floating) is connec-
ted as follows (see fig. 12):
1) Connect the floating opener contact to terminals 12
(STOP or emergency-OFF input) and 13.
2) Set DIP switch 1 to OFF.
Note
By opening the contact any possible travel cycles are
immediately halted and permanently prevented. The
operator lighting signals the impulse code 1x flashing
and LED 5 flashing.
3.5.4 Connecting a photocell or a closing edge safety
device to initiate a safety return up to the "OPEN"
end-of-travel position
A photocell (safety device) that has a floating opener
contact is connected as follows (see fig. 13):
1) Connect the floating opener contact to terminals 71
(safety input) and 20 (0 V).
2) Connect terminals 5 (approx. + 24 V) and 20 (0 V) to
the voltage supply. Max. current 100 mA.
3) Set DIP switch 2 to OFF.
Note
If during the closing cycle the photocell is interrupted, the
door reverses and travels to the "OPEN" end-of-travel posi-
tion. If the automatic timer is activated, the time is reset, i.e.
as soon as the photocell is clear again, the set time phase
restarts. The connection is only active during the closing
cycle. The operator lighting signals the impulse code 1x
flashing and LED 5 glows.
3.5.5 Connecting a closing edge safety device 8.2 kΩ
A closing edge safety device with 8.2 kΩ-resistance is
connected as follows (see figure 14):
1) Connect the floating opener contact to terminals 74
(safety input) and 20 (0 V).
2) Set DIP switch 3 to OFF.
Note
The input is active in "CLOSE" and "OPEN". When the
door is closing, a reverse takes place up to the "OPEN"
end-of-travel position. When the door is opening, it is
not "interrogated" until after approx. 50 HALL impulses
(approx. 50 mm) and brings about an immediate stop.
The operator lighting signals the impulse code 1x flashing
and LED 2 glows.

3.5.6 Connecting an additional relay to control a light

The floating contacts of the option relay enable the
external garage lighting to be switched parallel to the
operator lighting. To supply power to an external light,
external voltage must be used!

Notes on operating the garage door operator

Note
Initial function checks as well as programming or extending
the remote control should always take place from inside the
garage.
Only ever operate the garage door operator provided
you have a full view of the door's area of movement.
Wait until the door has come to a complete halt before
entering the door's area of movement.
Before driving in or out of the garage, always check that
the door has fully opened.
ATTENTION
Keep hand transmitters out of the
reach of children!
The function of the mechanical release should be
checked every month. The pull cord with knob may
only be actuated when the door is closed, otherwise
with weak, broken or defective springs or due to inade-
quate counterbalancing, there is a risk that the door
could close too quickly.
ATTENTION
Never hang bodily from the pull cord
with knob!
All persons using the door system must
be shown how to operate the garage
door operator properly and safely. Demon-
strate and test the mechanical release as
well as the safety return. To do this, halt
the movement of 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

In the normal operation mode the garage door operator
works entirely according to impulse repetition control,
whereby it makes no difference whether an external
button, a programmed-in hand transmitter button or
the test button on the control PCB is pressed:
1st impulse: The door travels towards an end-of-travel
position.
2nd impulse: the door stops.
