K120M CHARACTERISTICS
LED - DL3
The LED, besides indicating that the power supply is connected, also signals errors with a series of
pre-defined flashes:
steady light: normal operation;
1 flash: buffer battery voltage lower than 17,3 V DC;
Check the mains power supply, charge the battery, replace the battery;
2 flashes: phototest error;
Disable phototest (dip-switch 6 OFF), check operation and connection of photocells;
3 flashes: power failure;
Check the thermal-magnetic circuit breaker (upstream from system), check the fuses;
4 flashes: max current limit exceeded;
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: absence of encoder signal;
Check wiring, check encoder through TEST-ENCODER (optional), verify that the motor turns freely if
powered directly by the 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 and that it slides smoothly;
7 flashes: no memorization procedure has been executed;
Execute memorization procedure.
8 flashes: no motor signal.
check wiring, check that the motor rotates freely when powered directly by battery, check fuse F2.

Gate contact open: The contact activates on opening the gate and remains
active during the open time, during the TCA and during reclosure. It deactivates
once the gate has completed its closure movement.
Bistable function active: the radio control impulse causes the contact to activate
and remain active until the subsequent impulse.
Monostable function active for 2 sec.: the radio control impulse causes the
contact to activate and remain active for 2 sec.
Monostable function active for 180 sec.: the radio control impulse causes the
contact to activate and remain active for 180 sec.
On RESISTIVE SENSITIVE EDGE (terminal no. 1);
Off FIXED EDGE (NC contact – terminal no. 1);
On the memorization function is enabled for self-learning of the travel;
leave the dip-switch in this position when the memorization procedure
