2 2 / 4 STROKE
On
when the automation is operational, a sequence of opening/closing
commands causes the gate to OPEN-CLOSE-OPEN-CLOSE etc.
Off
under the same circumstances, the same sequence of commands
causes the gate to OPEN-STOP-CLOSE-STOP-OPEN-STOP, etc.
(step-by-step function) (see also dip switch 4);
3
MOTORS
SELECTION
On enables just one motor (M1);
Off enables 2 motors;
4
NO
REVERSE
On the gate behaves as established by dip switch no. 2;
Off
the gate ignores the closing commands during the opening manoeu-
vre and during the automatic closing time. Therefore the A/C input
works only by opening command;
5
PRE-
FLASHING
On the pre-ashing function is enabled;
Off the pre-ashing function is disabled;
6 FOTOTEST
On the “photocell test” function is enabled;
Off
the “photocell test” function is disabled. N.B.: to be used when the
photocells are not used;
7
CLOSE
AFTER
PHOTOCELL
On
following the connection of the photocell contact (input 15 - 17), the
gate closes automatically after 5 seconds;
Off function disconnected;
8 MEMO
On the memorization function is enabled for self-learning of the travel;
Off
leave the dip-switch in this position when the memorization proce-
dure has been completed.
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 18 - 20 (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-dened ashes:
steady light: normal operation;
1 ash: buffer battery voltage lower than 11,3V DC;
Check the mains power supply, charge the battery, replace the battery;
2 ashes: phototest error;
Disable phototest (dip-switch 6 OFF), check operation and connection of photocells;
3 ashes: power failure;
Check the thermal-magnetic circuit breaker (upstream from system), check the fuses;
4 ashes: 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 ashes: 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;
