Work Time adjustment: from approx. 4 to 64 seconds.
The D727M control unit is equipped with the "MEMORY OF THE WORKING
TIMES" function. This function means that the first manoeuvre must be left to
completely finish without interrupting the travel of the motor (operation time
regulated by the T.L. Trimmer). Otherwise, turn off the mains power supply,
wait about 5 seconds, turn on the power supply and repeat the procedure.

5. FEATURES OF THE D727M
LED - DL1
As well as indicating power-on, the LED also indicates faults by means of a series of predefined
selected working voltage input;
ADJUSTMENT OF MOTOR THRUST
The higher the selected voltage, the greater the thrust of the
gearmotor;
low voltage input for powering auxiliary and logic circuits
(25 = 0 Vac - 26 = 12 Vac - 27 = 24 Vac);
433,92 MHz built-in radio-receiver aerial input
(28 = EARTH - 29 = SIGNAL).
after opening, the gate automatically closes when the delay set on the
On
T.C.A. trimmer expires;
Off a manual command is required to close the gate;
with automatic closing enabled, a sequence of open/close commands
On
causes the gate to OPEN-CLOSE-OPEN-CLOSE etc.;
in the same conditions, the same command sequence causes the gate to
Off
OPEN-STOP-CLOSE-STOP-OPEN-STOP, etc. (step-by-step) (see also dip switch 4);
during opening, the photocell cuts in to stop the gate until the obstacle
On
is removed. During closing, it stops the gate and then totally reopens it.
during opening, the photocell does not trigger while during closing, it
Off
behaves as if the dip switch were on;
On the gate works as set by dip switch 2
the gate ignores the close command during the opening cycle (apartment

block function);
On pre-flashing function enabled;
Off pre-flashing function disabled;
On
"photocell test" function enabled;
Off "photocell test" function disabled. N.B.: used when photocells are not used;
bistable (or STEP-BY-STEP) function of the CH2 control relay (terminals 9
On
and 10) enabled;
monostable function of the CH2 control relay (terminals 9 and 10)
Off
enabled;
with dip-switch 7 OFF (monostable function), the N.O. contact remains
On
closed for 180 secs. (fixed invariable delay for the timed control of the lights);
with dip-switch 7 OFF (monostable function), the N.O. contact remains
Off closed for 2 secs. (fixed invariable delay for commanding a second
automatic system).
