1 - 2 auxiliary circuits output 18 Vdc max. 15 W (1 = NEGATIVE - 2 = POSITIVE) for
photocells, relays, receivers, etc...;
3 - 4 18 Vdc output for transmitter photocell – phototest - (3 = NEGATIVE - 4 = POSITIVE)
max. no. 1 photocell transmitter;
5 - 6 18 Vdc max. 20W output for flashing light supply (5 = NEGATIVE - 6 = POSITIVE),
flashing signal supplied by the control unit, rapid for closing, slow for opening;
7 - 8 18 Vdc max. 3W output for supply to open and moving gate warning light (7 =
NEGATIVE - 8 = POSITIVE);
9 - 11 N.C. input for electromechanical sensitive edge – it cuts in during the opening
manoeuvre, locking and re-closing the gate by ~20 cm (9 = C.F. - 11 = COM);
10 - 11 N.C. photocell input - it cuts in during the closing or the opening manoeuvre, see
dip-switch no. 3 (10 = FOT - 11 = COM);
N.B. The photocell transmitter must always be supplied by terminals no. 3 and no.
4, since the safety system test (phototest) is carried out on it. Without this
connection, the control unit does not work. To override the testing of the safety
system, or when the photocells are not used, set dip-switch no. 6 to OFF.
transmitters of possible pairs of additional photocells have always to be fed by
terminals 1 and 2.
12 - 13 N.C. input for STOP button – It stops the gate in any position, temporarily inhibiting
its automatic closing, if programmed (12 = COM - 13 = STOP);
12 - 14 N.O. input for OPEN/CLOSE button - It commands the opening and closing of the
gate and its operation is controlled by dip-switches 2 and 3 ( 12 = COM - 14 = A/C);
12 - 15 N.O. input for PEDESTRIAN button - It commands the partial opening and closing of
the gate for ~1 m of travel and its operation is controlled by dip-switches 2 and 3 (12
= COM - 15 = PED);
16 - 17 plug-in radio-receiver aerial input , for 40.665 MHz receivers only (16 = SIGNAL - 17
= GROUND);
18 - 19 2 radio channel output - for control of an additional automation or for switching on
nd
lights, etc... (N.O. clean contact);
20 - 21 - 22 encoder supply and input (20 = BROWN positive - 21 = WHITE signal - 22 =
BLUE negative);
23 - 24 motor supply output 18 Vdc max. 50 W;
FS1 - FS2 board supply input 13.5 Vac – Powered by the toroidal transformer housed in the
SPEED 2 motor and protected by a fuse on the 230 Vac power supply ;
IMPORTANT:
do not connect auxiliary relays so as to avoid endangering the correct functioning of

the control unit;
do not connect switching feeders or similar apparatus close to the control unit that

may be a source of disturbance;
