TIMER-OPERATED OPENING AND CLOSING CYCLES
The opening and closing of the gate can be controlled through a digital timer equipped with a
relay contact on the output. The timer must be connected to terminals 12 - 14 (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).
The automatic closing function must be enabled by setting Dip-switch no. 1 to ON).
D747M CHARACTERISTICS
LED - DL3
The LED, besides indicating that the power supply is connected, also signals errors with a series
of pre-defined flashes:
steady light: normal operation;
1 flash: buffer battery voltage lower than 11,3V DC;
Check the mains power supply, charge the battery, replace the battery;
2 flashes: phototest error;
Disable phototest (dip-switch 6 OFF), check operation and connection of photocells;
3 flashes: power failure;
Check the thermal-magnetic circuit breaker (upstream from system), check the fuses;
4 flashes: max current limit exceeded;
Gearmotor has exceeded absorption limits, check for obstacles across the path of the gate,
check the current absorption of the motor when loadless and under load;
5 flashes: absence of encoder signal / no motor signal;
Check wiring, check encoder through TEST-ENCODER (optional);
Check wiring, check that the motor rotates freely when powered directly by battery, check fuse F2;
when the automation is operational, a sequence of opening/closing
On
commands causes the gate to OPEN-CLOSE-OPEN-CLOSE etc.
under the same circumstances, the same sequence of commands
Off
causes the gate to OPEN-STOP-CLOSE-STOP-OPEN-STOP, etc.
(step-by-step function) (see also dip switch 4);
On enables just one motor (M1);
Off enables 2 motors;
On the gate behaves as established by dip switch no. 2;
the gate ignores the closing commands during the opening manoeu-
Off vre and during the automatic closing time. Therefore the A/C input
works only by opening command;
On the pre-flashing function is enabled;
Off the pre-flashing function is disabled;
On the "photocell test" function is enabled;
the "photocell test" function is disabled. N.B.: to be used when the
Off
photocells are not used;
following the connection of the photocell contact (input 15 - 17), the
On
gate closes automatically after 5 seconds;
Off function disconnected;
On the memorization function is enabled for self-learning of the travel;
leave the dip-switch in this position when the memorization proce-
Off
dure has been completed.
