7 on: following the connection of the photocell contact (input 10 - 11), the gate closes
automatically after 5 seconds;
off: function disconnected;
8 on: the memorization function is enabled for self-learning of the travel;
off: leave the dip-switch in this position when the memorization procedure has been
completed.
Clock function:
A timer can be connected to the open-close pushbutton in order to keep the gate open at certain
times during the day, after which it reverts to automatic closing.

The LED, besides indicating that the power supply is connected, also signals errors with a series
of pre-defined flashes:
• steady light:
• 1 flash:
Check the mains power supply, charge the battery, replace the battery;
• 2 flashes:
Disable phototest (dip-switch 6 OFF), check operation and connection of photocells;
• 3 flashes:
Check the thermal-magnetic circuit breaker (upstream from system), check the fuses;
• 4 flashes:
Gearmotor has exceeded absorption limits, check for obstacles across the path of the gate,
check the current absorption of the motor when loadless and under load;
• 5 flashes:
Check fuse F2 and wiring, check encoder through TEST-ENCODER (optional)
• 6 flashes:
Make sure there are no obstacles across the path of the gate and that it slides smoothly;
• 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 will continue to be
signalled until a complete opening and closing manoeuvre is executed.
