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. 2 photocell transmitters;
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 max. 18 Vdc 3W electromagnetic power supply output (7 = NEGATIVE - 8 =
POSITIVE);
9 - 11 CLOSE button N.O. input – Controls the total closure of the bar (9 = CLOSE - 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.
12 - 13 STOP button N.C. input – Stops the bar in any position, temporarily preventing the
automatic closure, if programmed (12 = COM - 13 = STOP);
12 - 14 OPEN/CLOSE button N.O. input – Controls the opening and closing of the bar and is
regulated based on the function of dip-switches 2 and 4 ( 12 = COM - 14 = O/C);
12 - 15 OPEN button N.O. input – Controls the total opening of the bar (12 = COM - 15 =
OPEN);
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 13.5 Vac control unit power supply input – Fed by the toroidal transformer and
protected by the fuses 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 barrier that may be

a source of disturbance;
