Description
board supply input 18,5 V AC – Powered by the toroidal trans-
former housed in the T-ONE3B motor and protected by a fuse
on the 230 V AC power supply.
SENSITIVE EDGE input (resistive sensitive edge or fixed safety
edge); Works only when the gate is opening; temporarily stops
the gate and partially closes it by about 20 cm in order to allow
the obstacle to be removed.
1= SENSITIVE EDGE, 3= COMMON.
Note: If a resistive sensitive edge is connected, set dip-
switch no. 9 to ON;
If a fixed safety edge with NC contact is connected,
set dip-switch no. 9 to OFF.
input for PHOTOCELLS OR SAFETY DEVICES active during
closure (Normally Closed contact); They stop the gate during
closing and totally reopen it; they temporarily stop the gate dur-
ing opening in order to allow the obstacle to be removed (if dip
switch n° 3 set to ON). If there is more than one safety device,
connect all the NC contacts in series. 2= PHOTOCELL.
Note: The photocell transmitter must always be supplied
by terminals no. 10 - 11, since the safety system test
(phototest) is carried out on it. To override the test-
ing of the safety system, or when the photocells are
not used, set dip-switch no. 6 to OFF. If the phototest
is not successful, the control unit will not operate.
STOP pushbutton input (Normally Closed contact); It stops the
gate in any position, temporarily inhibiting its automatic closing,
if programmed. 4= COMMON, 5= STOP.
OPEN/CLOSE pushbutton input (Normally Open contact); It
commands the opening and closing of the gate and its operation
is controlled by dip-switches 2 and 4. 5= OPEN/CLOSE.
PEDESTRIAN pushbutton input (Normally Open contact); 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 4.
7= PEDESTRIAN.
24 V DC, max. 15 W, output to POWER THE RXs AND ANY
OTHER TXs OF PHOTOCELLS THAT ARE PRESENT, EX-
TERNAL RECEIVERS, etc.; connect a max. of 3 pair of photo-
cells. 8= NEGATIVE, 9= POSITIVE.
24 V DC, output for PHOTOCELL TX (only the one that performs
the Phototest) max. no. 1 photocell transmitter. 10= NEGATIVE,
11= POSITIVE.
FLASHING LIGHT output 24 V DC, max. 20 W. The signal is al-
ready modulated for direct use. Flashing frequency during clos-
ing is double. 12= NEGATIVE, 13= POSITIVE.
GATE OPEN LED output 24 V DC, max. 3 W; during opening of
the gate the warning light flashes slowly, when the gate is open
it remains steadily illuminated and during closure it flashes twice
as fast. 14= NEGATIVE, 15= POSITIVE.
2 RADIO CHANNEL output (its operation depends on dip-
nd
switches nos. 7 - 8) to be used for opening/closing another gate,
for controlling garden lights or for the "ZONE LIGHTING" func-
tion.
Warning: to connect other devices to the 2nd Radio Chan-
nel (area lighting, pumps, etc.), use an additional
auxiliary relay
