3 on:
enables just one motor (M1);
off:
enables 2 motors;
4 on: the gate behaves as established by dip switch no. 2;
off: the gate ignores the closing commands during the opening manoeuvre;
5 on: the pre-fl ashing function is enabled;
off: the pre-fl ashing function is disabled;
6 on: the "photocell test" function is enabled;
off: the "photocell test" function is disabled. N.B.: to be used when the photocells are not used;
7 on: following the connection of the photocell contact (input 15 - 17), 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.
LED - DL3
The LED, besides indicating that the power supply is connected, also signals errors with a series of
pre-defi ned fl ashes:
• 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), check operation and connection of photocells;
• 3 fl ashes:
Check the thermal-magnetic circuit breaker (upstream from system), check the fuses;
• 4 fl ashes:
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 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 and that it slides smoothly;
• 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 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.
