Off
Gate contact open:
The contact activates on opening the gate and remains ac-
tive during the open time, during the TCA and during reclosure. It deactivates
once the gate has completed its closure movement.
Off

Bistable function active:
the radio control impulse causes the contact to activate
and remain active until the subsequent impulse.

K125M 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 11.3 Vdc;
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.
