D749MA CHARACTERISTICS
TIMER-OPERATED OPENING AND CLOSING CYCLES
The opening/closing of the automation can be controlled by means of a timer that has a free N.O.
output contact (relay). The timer must be connected to terminals 4 - 6 (OPEN/CLOSE button) and
can be programmed so that, at the desired opening time, the relay contact closes until the desired
closing time (when the timer's relay contact opens, enabling the automatic closing of the gate).
Note: the automatic closing function must be enabled by setting Dip-switch no. 1 to ON).
BATTERY CHARGER BOARD (INTEGRATED)
If the battery is connected the automation will operate in any case if there is no mains power
supply. If the voltage drops below 11.3 Vdc, the automation ceases to operate (the control unit
remains fed); whereas, when the voltage drops below 10.2 Vdc, the card completely disconnects
the battery (the control panel is no longer fed).
OBSTACLE DETECTION
If the obstacle detection function (which can be set through trimmer FR) is activated during an
opening manoeuvre, the gate closes approx. 20 cm., if it is activated during a closing manoeuvre,
the gate opens all the way .
WARNING: the control panel logics may interpret mechanical friction as an obstacle.
