TERMINAL BOARD CONNECTIONS
Terminals Function
Description
1 - 2
AUX
auxiliary circuits output 18V DC max. 15 W for photocells,
relays, receivers, etc... (1 = NEGATIVE - 2 = POSITIVE)
3 - 4
TX PHOTOCELLS
18V DC output for transmitter photocell – phototest - max.
no. 1 photocell transmitters. (3 = NEGATIVE - 4 = POSITIVE)
5 - 6
FLASHING LIGHT
18V DC max. 20 W output for flashing light supply, flashing
signal supplied by the control unit, rapid for closing, slow for
opening. (5 = NEGATIVE - 6 = POSITIVE)
7 - 8
GATE OPEN
WARNING LIGHT
18V DC max. 3 W output for supply to open and moving gate
warning light. (7 = NEGATIVE - 8 = POSITIVE)
9 - 10
ELECTRIC
LOCK
12V AC, 15 W output for electric lock.
11 - 12
2
nd
CH RADIO
2
nd
radio channel output - for control of an additional automa-
tion or for switching on lights, etc... (N.O. clean contact)
Warning: to connect other devices to the 2nd Radio
Channel (area lighting, pumps, etc.), use an additional
auxiliary relay (see note at end of paragraph).
13 - 14
AERIAL
plug-in radio-receiver aerial input.
(13 = SIGNAL - 14 = GROUND)
15 - 17
EXTERNAL
PHOTOCELLS
PHOTOCELL OR SAFETY DEVICE input OUTSIDE the gate
(Normally Closed contact). Then these devices trigger during
the closing phase, they stop the gate and then totally open it
again. 17 = COMMON.
Note: 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.
16 - 17
INTERNAL
PHOTOCELLS
PHOTOCELL OR SAFETY DEVICE input INSIDE the gate
(Normally Closed contact). When these devices trigger dur-
ing the opening phase, they temporarily stop the gate until
the obstacle has been removed; during the closing phase
they stop the gate and then totally open it again.
18 = COMMON.
18 - 19
STOP
N.C. input for STOP button – It stops the gate in any position,
temporarily inhibiting its automatic closing, if programmed.
(18 = COM - 19 = STOP)
18 - 20
OPEN/CLOSE
N.O. input for OPEN/CLOSE button - It commands the open-
ing and closing of the gate and its operation is controlled by
dip-switches 2 and 3. (18 = COM - 20 = O/C)
18 - 21
PEDESTRIAN
PEDESTRIAN button N.O. input – Controls the total opening
and closing of motor 1 (M1) and the functioning is regulated
by dip-switches 2 and 4. (18 = COM - 21 = PED)
22 - 23
MOTOR 2
motor 2 (M2) supply output 18V DC max. 50 W.
24 - 25 - 26
ENCODER (M2)
encoder supply and input. (24 = WHITE signal - 25 = BLUE
negative - 26 = BROWN positive)
27 - 28
MOTOR 1
motor 1 (M1) supply output 18V DC max. 50 W.
29 - 30 - 31
ENCODER (M1)
encoder supply and input. (29 = WHITE signal - 30 = BLUE
negative - 31 = BROWN positive)
