9. K996M CHARACTERISTICS

LED - DL5

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;

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 overhead door, 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)

6 flashes:

presence of obstacle after 5 failed attempts to close;

Make sure there are no obstacles across the path of the overhead door 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.

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 detection),

the control unit opens completely indicating the error with the provided series of

manoeuvre, the control unit will stop flashing and will switch to slow-down mode as it searches for the

closing travel limit.

If the sensitive edge are activated 5 consecutive times during the same closing manoeuvre (obstacle

detection), the control unit opens completely and stops without flashing.

noeuvre, you need a new command.

COURTESY LIGHT (18 Vdc - max. 15W)

The open gate indicator light comes on when an open command is given, and it stays on throughout

the manoeuvre and during the pause time; it goes off 2 minutes after the gate has closed.

BATTERY CHARGER BOARD (OPTIONAL)

If the system is equipped with a battery charger board, it con operate even during power failures. If

the voltage drops below 11.3 Vdc, the automation stops working (the control panel is still powered).

When it drops below 10.2 Vdc, the board disconnects the battery completely (the control panel is no

longer powered).
