Connecting a pull switch
On the screw terminals 56 & 57 a pull switch (NO contact) can be connected.

automatic closing function (ON /OFF)
It is possible to switch or switch off the automatic closing time by connecting an external
timer to the screw terminals 54 & 55.

automatic closing function ON automatic closing function OFF
In the event of the automatic closing function being switched on permanently the screw ter-
minals 54 & 55 have to be bridged.
The function of the pull switch is
UP/STOP/DOWN/STOP.
Connecting a photo-cell (optional, only if Comfort module is connected!)
To connect a photo-beam to cover the ‘drive through’ area the photo-beam is connected to
the terminals 51, 52 & 53. If the infrared beam of the photo-beam is broken during the
DOWN direction the door will stop and reverse to a fully open position. It is possible to con-
figure the Comfort module so that when the photo-beam is activated by traffic the automatic
closing time is reduced to 5 seconds.
Using a photo-cell with receiver and transmitter, the power supply is connected to the
terminals 52 & 53.

Connecting an opto-electric FRABA-Safety edge
It is possible to connect to the DC 3 an electric, pneumatic or opto-electronic (FRABA) type
Safety Edge device directly to the terminals 48, 49 & 50 without any specific control boxes.
The controlling of the safety edge is managed by the Comfort module and therefore there
is no need for an additional safety edge management device.

Opto-electric safety edge - FRABA
terminal 48 = Safety edge (-GND)
terminal 49 = Safety edge (Signal)
terminal 50 = Safety edge (+ 15V)
Connecting an electro mechanical safety edge
(optional, only if Comfort module is connected!)
The controlling of the safety edge is managed by the Comfort module and there is therefore
no need for an additional safety edge controller.
For this purpose the DC 3 has an intelligent testing device which recognises when the door
has finished the closing cycle. In order to check it is necessary to connect a resistor on the
opposite end of the safety edge (cable connection).

Because the function of the safety-edges is automatically checked by the Comfort module
there is normally no need to test it. In this case the screw terminals 46 & 47 of the pre-limit
switch can be bridged. In situations where the rubber of the safety edge needs to touch the
ground you have to control this with a pre-limit switch (adjustment 5 cm above ground),
thus preventing the door to stop and return.
