8. 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.
If the encoder is activated 5 consecutive times during the same closing manoeuvre (obstacle detec-
tion), the control unit opens completely indicating the error with the provided series of
next manoeuvre, the control unit will stop flashing and will switch to slow-down mode as it searches
for the closing travel limit.
If the photocells are activated 5 consecutive times during the same closing manoeuvre (obstacle detec-
tion), the control unit opens completely and stops without flashing.
vre, you need a new command.
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).
On
the memorization function is enabled for self-learning of the travel;
leave the dip-switch in this position when the memorization procedure
Off
has been completed.
