Key:
N.C. = Normally Closed
N.O. = Normally Open
1 - 2 POWER input 230Vac, 50Hz, single-phase;
M2 transformer primary connector [1 blue wire (230V) + 1 red wire (V_SET) + 1 black wire
(0V)];
Tuning of the engines power
The red wire (V_SET) allow to select the output-voltage of the engines, consequently
their thrust-forces.
M5 transformer secondary connector [1 blue wire (0V) + 1 brown wire (15V) + 1 white wire
(24V) + 1 black wire (0V) + 1 red wire (12V)];
3 - 4 FLASHING LIGHT output 230Vac, 20W max. The signal is already modulated for direct
use. Flashing frequency increases slightly during closing;
5 - 6 - 7 MOTOR M1 power output (opens the leaf fi tted with the electric lock), 230 Vac, max. 300
W. 5=CLOSE, 6=COMMON, 7=OPEN.
N.B.: connect the capacitor between terminals 5 and 7;
8 - 9 -10 MOTOR M2 power output, 230 Vac, max. 300 W. 8=CLOSE, 9=COMMON., 10=OPEN.
N.B.: connect the capacitor between terminals 8 and 10;
11 - 12 OPEN/CLOSE button input (contact normally open); for operating information see dip
switch 2 and 8 functions (COMMON=11);
11 - 13 N.O. PEDESTRIAN button contact input – commands total opening and closing of motor
1 – governed by dip-switches 2 and 4 (COMMON=11);
11 - 14 STOP button input (normally closed contact); this stops the automatic system. At the next
command, the opposite operation to the previous one is performed (COMMON=9);
15 - 18 PRESSURE-SENSITIVE EDGE input (Normally Closed contact);
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. (COMMON=18).
16 - 18 PHOTOCELL OR SAFETY DEVICE input INSIDE the gate (Normally Closed contact);
COMMON=18.
When these devices trigger during 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.
17 - 18 PHOTOCELL OR SAFETY DEVICE input OUTSIDE the gate (Normally Closed contact);
COMMON=18.
Then these devices trigger during the closing phase, they stop the gate and then totally
open it again.
N.B. Because the control of the safety system is performed on the photocell's transmitter,
this must always be powered by terminals 25 – 27, therefore if this connection is
