8 MEMO
Clock function:
A timer can be connected to the open-close pushbutton in order to keep the gate open at certain
times during the day, after which it reverts to automatic closing.
K123M 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 / no motor signal;
Check wiring, check encoder through TEST-ENCODER (optional);
Check wiring, check that the motor rotates freely when powered directly by 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.
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. On the next manoeuvre, the control unit will switch
to slow-down mode as it searches for the closing travel limit.
GATE OPEN WARNING LIGHT (18 Vdc - max. 3W)
The gate open warning light flashes during the opening or closing manoeuvre in synchrony with
the flashing light, then shows a steady light when the gate has opened completely. Once the
closing manoeuvre has been completed this light goes off .
In addition, the gate open warning light signals the following:
programming phase (when dip-switch 8 is set to ON);
it flashes in sync with the flashing light;
mains power supply restored
it emits a series of flashes for approx. 2 seconds;
presence of obstacles across the path of the gate after 5 attempts to close have failed;
it flashes in sync with the flashing light.
On the memorization function is enabled for self-learning of the travel;
leave the dip-switch in this position when the memorization proce-
Off
dure has been completed.
