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:
• 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 wiring, check encoder through TEST-ENCODER (optional), verify that the motor turns
freely if powered directly by the battery, check fuse F2;
• 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:
check wiring, check that the motor rotates freely when powered directly by battery, check fuse F2.
Multiple errors are signalled by a 2-second pause between signals. Errors will continue to be sig-
nalled until a complete opening and closing manoeuvre is executed.
If the safety devices are activated 5 consecutive times during the same opening or closing manoeu-
vre, 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.
BATTERY CHARGER BOARD (INTEGRATED)
If the battery is connected the automation will operate in any case if there is no mains power supply.
If the voltage drops below 11.3 Vdc, the automation ceases to operate (the control unit remains fed);
whereas, when the voltage drops below 10.2 Vdc, the card completely disconnects the battery (the
control panel is no longer fed).
Gate contact open: The contact activates on opening the gate and remains
active during the open time, during the TCA and during reclosure. It deacti-
vates once the gate has completed its closure movement.
Bistable function active: the radio control impulse causes the contact to acti-
vate 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.
