Multiple errors are signalled by a 2-second pause between signals. Errors will continue to be
signalled until a complete opening and closing manoeuvre is executed.
If the safety devices are activated 5 consecutive times during the same opening or closing
manoeuvre, the control unit will switch to slow-down mode as it searches for the closing travel
limit. To reset, the gate must execute a complete opening and closing cycle, otherwise the travel
limit search phase will start again each time the safety devices are activated.
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-defined flashes, which last for max 30
seconds.
• steady light:
• 1 flash:
Check the mains power supply, charge the battery, replace the battery.
• 2 flashes:
Disable phototest (dip-switch 6 OFF)
• 3 flashes:
Check the thermal-magnetic circuit breaker (upstream from system), check the hour coun-
ter.
• 4 flashes:
Excessive absorption peaks of the gearmotor, check that there are no obstacles throughout
the movement of the bar, check the motor's absorption of current when loadless and applied
to the bar;
• 5 flashes:
Check wiring, check encoder through TEST-ENCODER (optional).
• 6 flashes:
Check that there are no obstacles throughout the movement of the bar and the balance of
the bar;
• 7 flashes:
Execute memorization procedure.
• 8 flashes:
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 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 (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).
