FEATURES OF THE D727M
GB
LED - DL1
As well as indicating power-on, the LED also indicates faults by means of a series of
predefi ned sequences of fl ashes:
•
steady:
•
1 fl ash:
Disable photo test (dip-switch 6 OFF), check photocells and relative connections;
•
2 fl ashes:
Check the gate for obstacles and make sure it swings smoothly;
•
3 fl ashes:
Reset manoeuvre counter.
N.B.: the version of the microprocessor installed in the control panel in your
possession does not count the number of manoeuvres.
More than one error is indicated by means of a 2 second pause between one signal and the
next. The fault indication continues until a complete manoeuvre (open and close) has been
performed.
GATE OPEN INDICATOR (24 Vac – max. 3W)
During the opening and closing cycles, the gate open indicator fl ashes in time with the LED
(fl ashing). It then remains steady when the gate is totally open. After the closing phase has
been completed, it turns off.
The gate open indicator also signals:
•
the presence of obstacles near the gate after 5 unsuccessful attempts to complete the
closing cycle;
fl ashes in time with the fl ashing light.
TIMED OPENING AND CLOSING
The gate can be opened and closed by means of a digital clock with a relay output contact.
Simply connect it to terminals 17 - 18 (OPEN/CLOSE button) and programme it so that, at
the required opening time, the relay contact of the clock closes until the required closing time
(when the relay contact of the clock opens once again, thereby allowing automatic closing).
N.B.: Automatic closing must be enabled (Dip-switch 1 ON).
SELECTING MOTOR INPUT VOLTAGE
Select the operating voltage of the motors (140 - 160 - 180 - 200 Vac) using terminal 24 on
the control board and the output for the required voltage on the transformer.
N.B.: DISCONNECT the transformer before selecting a voltage.
ok;
photo test error after three unsuccessful attempts;
obstacle present after 5 unsuccessful attempts to complete the closing
cycle;
max. number of programmed manoeuvres exceeded (optional).
