Obstacle Detection - tau D747M Notice D'installation

FLASHING LIGHT (18 Vdc - max. 20W)
Besides signalling the opening and closing of the gate, at the end of the opening or closing
manoeuvre it also signals errors with a series of pre-defi ned fl ashes, which last for max 30
seconds.
• steady light:
• 1 fl ash:
Check the mains power supply, charge the battery, replace the battery.
• 2 fl ashes:
Disable phototest (dip-switch 6 OFF)
• 3 fl ashes:
Check the thermal-magnetic circuit breaker (upstream from system), check the hour counter.
• 4 fl ashes:
Gearmotor has exceeded absorption limits, check for obstacles along the path of the gate.
• 5 fl ashes:
Check wiring, check encoder through TEST-ENCODER (optional).
• 6 fl ashes:
Make sure there are no obstacles across the path of the gate.
• 7 fl ashes:
Execute memorization procedure.
• 8 fl ashes:
Reset manoeuvre counter
N.B.: The microprocessor version installed in your control panel is not enabled for
manoeuvre counting.
Multiple errors are signalled by a 2-second pause between signals. Errors continue to be
signalled until a complete opening and closing manoeuvre is executed.
GATE OPEN WARNING LIGHT (18 Vdc - max. 3W)
The gate open warning light fl ashes during the opening or closing manoeuvre in synchrony with the
fl ashing light, then shows a steady light when the gate has opened completely. Once the closing
manoeuvre has been completed this light goes off .
In addition, the gate open warning light signals the following:
• programming phase (when dip-switch 8 is set to ON);
it fl ashes in sync with the fl ashing light;
• mains power supply restored
it emits a series of fl ashes for approx. 2 seconds;
• presence of obstacles across the path of the gate after 5 attempts to close have failed;
it fl ashes in sync with the fl ashing light.
BATTERY CHARGER BOARD (OPTIONAL)
If the system is equipped with a battery charger board, it con operate even during power failures. If
the voltage drops below 11.3 Vdc, the automation stops working (the control panel is still powered).
When it drops below 10.2 Vdc, the board disconnects the battery completely (the control panel is
no longer powered).

OBSTACLE DETECTION

If the obstacle detection function (which can be set through trimmer FR) is activated during an
opening manoeuvre, the gate closes approx. 20 cm., if it is activated during a closing manoeuvre,
the gate opens all the way .
WARNING: the control panel logics may interpret mechanical friction as an obstacle.
