8 D755M
The D755M panel features an electronic photocell control system which switches the external
photocell transmitter on and off thereby causing the control unit microprocessor to check whether the
relay switches correctly. If this does not happen, the control unit is automatically blocked

TERMINAL BOARD CONNECTIONS
1 - 2 Power input 220/230 Vac 50 Hz
3 - 4 Flashing light output 230 Vac 50 W max. The signal is already modulated for direct use.
Flashing frequency increases slightly during closing.
5 - 6 - 7 M1 motor output single-phase 230 Vac 300 W max.
Common = 6; opening phase = 5; closing phase = 7
Connect the capacitor between terminals 5 and 7. Motor set for pedestrian use
8 - 9 - 10 M2 motor output single-phase 230 Vac, 300 W max.
Common = 9; opening phase = 8; closing phase = 10
Connect the capacitor between terminals 8 and 10.
11 - 12 24 Vac, 10 W output for powering photocells, external receivers, etc..
13 - 14 24 Vac output for powering the external TX photocell. For checking safety systems. (only
connect the external TX photocell) max. no. 1 photocell transmitter
14 - 15 24 Vac, 3W output for gate open indicator. The LED turns on when the opening manoeuvre
starts and turns off after closing (after T.L. working time elapsed).
16 - 17 12 Vac, 15 W output for electric lock..
18 - 19 PHOTOCELL OR SAFETY DEVICE input INSIDE the gate (Normally Closed contact); 18
= COMMON.
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.
18 - 20 PHOTOCELL OR SAFETY DEVICE input OUTSIDE the gate (Normally Closed contact);
18 = COMMON.
Then these devices trigger during the closing phase, they stop the gate and then totally
open it again.
N.B. The photocell transmitter must always be supplied (term. 13-14 power input – term. 18-20
n.c. contact) as it is used to check the safety system; without this connection, therefore, the
control unit will not power the actuators. To disable the safety system check move dip switch
n° 5 to OFF.
18 - 21 STOP button input (Normally Closed contact); this stops the gate. The gate opens after the
following command. 18 = COMMON.
18 - 22 PEDESTRIAN pushbutton input (Normally Open contact); this is similar to the OPEN/
CLOSE pushbutton, but only for the wing associated with the M1 motor which is used to
control pedestrian traffic. 18 = COMMON.
18 - 23 OPEN-CLOSE pushbutton input (Normally Open contact); for operating instructions,
please refer to dip-switch nos. 2 and 3 18 = COMMON
24 - 25 Aerial input, 24 SIGNAL, 25 SHIELD
26 - 27 2° RADIO CHANNEL output.
LOGIC ADJUSTMENTS (TRIMMER)
T.L. Work time adjustment from 5 to 80 seconds.
T.C.A. Automatic closing time adjustment from 2 to 130 seconds. (see dip-switch n° 1)
RIT. 2nd wing closing delay adjustment from 2 to 30 seconds.
