• POSSIBILITY OF ENERGY SAVING OPERATION
ATTENTION:
- 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;
- we recommend to use the TAU cable code M-03000010C0 to connect the motors to the control
board.
- In case of long sections of cables (> 20 m) for N.O./N.C. controls (e.g. OPEN / CLOSE, STOP,
PEDESTRIAN, 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. INTRODUCTION
The D749MA-R board has two working modes, selectable through the J6 jumper (see wiring diagram).
J6 Jumped:
J6 Not jumped:
Once the connection is achieved, in low-energy mode, press the PROG button briefly:
• 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.

through jumper J7 is no longer necessary (make sure whether it is
present on the control board or not).
