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.
K122M 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 11.3V DC;
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);
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;
Multiple errors are signalled by a 2-second pause between signals. Errors will continue to be
signalled until a complete opening and closing manoeuvre is executed.
If the safety devices are activated 5 consecutive times during the same opening or closing ma-
noeuvre, 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.
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.
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 pow-
ered). When it drops below 10.2 Vdc, the board disconnects the battery completely (the control
panel is no longer powered).
