FLASHING LIGHT (18 Vdc - max. 20W)
Besides signalling the opening and closing of the gate, at the end of the opening or closing ma-
noeuvre it also signals errors with a series of pre-defined flashes, which last for max 30 seconds.
• steady light:
normal operation;
• 1 flash:
buffer battery voltage lower than 11.3 Vdc;
Check the mains power supply, charge the battery, replace the battery.
• 2 flashes:
phototest error;
Disable phototest (dip-switch 6 OFF)
• 3 flashes:
power failure;
Check the thermal-magnetic circuit breaker (upstream from system), check the hour counter.
• 4 flashes:
max current limit exceeded;
Gearmotor has exceeded absorption limits, check for obstacles along the path of the gate.
• 5 flashes:
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;
• 6 flashes:
presence of obstacle after 5 failed attempts to close;
Make sure there are no obstacles across the path of the gate.
• 7 flashes:
no memorization procedure has been executed;
Execute memorization procedure.
Multiple errors are signalled by a 2-second pause between signals. Errors continue to be sig-
nalled until a complete opening and closing manoeuvre is executed.
GATE OPEN WARNING LIGHT (18 Vdc - max. 3W)
The gate open warning light flashes during the opening or closing manoeuvre in synchrony with
the flashing 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 flashes in sync with the flashing light;
• mains power supply restored
it emits a series of flashes for approx. 2 seconds;
• presence of obstacles across the path of the gate after 5 attempts to close have failed;
it flashes in sync with the flashing light.
BATTERY CHARGER BOARD (INTEGRATED)
If the battery is connected the automation will operate in any case if there is no mains power
supply. If the voltage drops below 11.3 Vdc, the automation ceases to operate (the control unit
remains fed); whereas, when the voltage drops below 10.2 Vdc, the card completely disconnects
the battery (the control panel is no longer fed)
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.
