POWER SUPPLY
SELECTION
selected working voltage input;
ADJUSTMENT OF MOTOR THRUST
The higher the selected voltage, the greater the thrust of the
gearmotor;
25 - 26 - 27
AUX
low voltage input for powering auxiliary and logic circuits
(25 = 0 Vac - 26 = 12 Vac - 27 = 24 Vac);
28 - 29
AERIAL
433,92 MHz built-in radio-receiver aerial input
(28 = EARTH - 29 = SIGNAL).
4. LOGIC ADJUSTMENTS
TRIMMERS
TCA
Automatic Closing Time adjustment: from approx. 5 to 245 seconds (see dip switch 1);
TRA
second motor delay adjustment during closing cycle: from approx. 1 to 16 sec.;
TL
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.
Dip-switches
1
AUTOMATIC
CLOSING
On
after opening, the gate automatically closes when the delay set on the
T.C.A. trimmer expires;
Off
a manual command is required to close the gate;
2
2 / 4 STROKE
On
with automatic closing enabled, a sequence of open/close commands
causes the gate to OPEN-CLOSE-OPEN-CLOSE etc.;
Off
in the same conditions, the same command sequence causes the gate to
OPEN-STOP-CLOSE-STOP-OPEN-STOP, etc. (step-by-step) (see also dip switch 4);
3
OPENING
PHOTOCELLS
OPERATION
On
during opening, the photocell cuts in to stop the gate until the obstacle
is removed. During closing, it stops the gate and then totally reopens it.
Off
during opening, the photocell does not trigger while during closing, it
behaves as if the dip switch were on;
4
NO
REVERSE
On
the gate works as set by dip switch 2
Off
the gate ignores the close command during the opening cycle (apartment
block function);
5
PRE-
FLASHING
On
pre-flashing function enabled;
Off
pre-flashing function disabled;
6
FOTOTEST
On
“photocell test” function enabled;
Off
“photocell test” function disabled. N.B.: used when photocells are not used;

RADIO CH
On
bistable (or STEP-BY-STEP) function of the CH2 control relay (terminals 9
and 10) enabled;
Off
monostable function of the CH2 control relay (terminals 9 and 10)
enabled;
8
On
with dip-switch 7 OFF (monostable function), the N.O. contact remains
closed for 180 secs. (fixed invariable delay for the timed control of the lights);
Off
with dip-switch 7 OFF (monostable function), the N.O. contact remains
closed for 2 secs. (fixed invariable delay for commanding a second
automatic system).
