16-17 OPEN/CLOSE (or STEP-BY-STEP) push button input. Dip-switches 3A and 1A (CONTROL CARD)
are used to control this input. DS 3A can be used to disable the inversion of direction during the
opening phase, while DS 1A enables the OPEN/STOP/CLOSE/STOP function; Normally Open
contact. (Common=17).
When DIP 1B is ON (2 motors) the open-close and pedestrian functions are active, if DIP 1B
is OFF (one motor) the following can happen:
when DIP8 is OFF the open-close and pedestrian functions are normal, when DIP8 is ON the
open-close button becomes just an open button while the pedestrian button becomes the
close button.
17-18 STOP BUTTON. This button stops the gate no matter what manoeuvre it's making. Press the OPEN/
CLOSE button to start the gate moving again.
Normally closed contact. (Common=17).
17-19 PHOTO DEVICE safety input for PHOTOCELLS, SAFETY EDGES, etc.. DIP 2A. is used to control
this function. Normally closed contact. (Common=17).
17-20 MOBILE SAFETY EDGE – PHOTO DEVICE controlled by DIP 1B.
Normally closed contact. (Common=17).
If DIP1 is OFF (1 motor), it works as a fixed edge, during the opening phase the control will cause
the gate to close for about 2 seconds.
If DIP1 is OFF (2 motors), it works as a photocell; if it cuts in during the closing phase the gate will
totally reopen, while it will remain inactive during the closing phase.
21-22-23 MOTOR 1 (M1) ENCODER INPUT.
Terminal n° 21,+ / brown,
Terminal n° 22, - / blue,

Terminal n° 22, - / blue,
Terminal n° 24 control pulse / white.
25-26 2 nd RADIO CHANNEL OUTPUT OF 2 nd RADIO CHANNEL
When a two channel receiver is used, the lighting installation, another piece of equipment, etc., can
be controlled.
Please see the receiver instructions for details of electrical connections.
27-28 RECEIVING AERIAL INPUT (Please also see further receiver instructions for 433.92 Mhz
frequency)
Connect the SHEATH to terminal n° 28 and the CABLE to terminal n° 27. If there is no suitable earth
connection the aerial sheath should not be connected.
29-30 13.5 V dc input from toroidal transformer (fig. 2 - 3).
31-32 230 V ac input to toroidal transformer (fig. 2 - 3).
33-34 230 V ac mains power supply input (fig. 2 - 3).
INSTALLATION
1- Position the card vertically.
2- Make sure to respect the polarities.
3- Different wires should be used for different circuits.
4- The cross-section of the cables of the mains line and the motor lines must be calculated to suit their
length and absorption levels.
recommended cross-section of power cables 1.5 mm² ;
recommended cross-section of motor cables 2.5 mm² ;
