-
do not use single cables (with one single wire), ex. telephone cables, in order to avoid break-
downs of the line and false contacts;
-
do not re-use old pre-existing cables.
-
In case of long sections of cables (> 20 m) for N.O./N.C. controls (e.g. OPEN / CLOSE, STOP, PEDE-
STRIAN, etc.), in order to avoid gate malfunctions, it will be necessary to uncouple the various
controls using RELAYS or using our 750T-RELE device.
2. TESTING
When you have completed the connection:
•
All the green LEDs must be on (each of them corresponds to a Normally Closed input). The go
off only when the controls to which they are associated are operated.
•
All the red LEDs must be off (each of them corresponds to a Normally Open input). The light
up only when the controls to which they are associated are operated. Except for the DL3
diagnostics led which must always be on.

Description
board supply input 18,5 V AC – Powered by the toroidal transformer
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 (Nor-
mally Closed contact); They stop the gate during closing and totally
reopen it; they temporarily stop the gate during 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 ter-
minals no. 10 - 11, since the safety system test (phototest) is car-
ried out on it. To override the testing 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.
