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:
• 1 flash:
Check the mains power supply, charge the battery, replace the battery;
• 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 over-
head door, check the current absorption of the motor when loadless and under load;
• 5 flashes:
Check wiring, check encoder through TEST-ENCODER (optional)
• 6 flashes:
Make sure there are no obstacles across the path of the overhead door 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
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.
FLASHING LIGHT (18 Vdc - max. 20W)
Besides signalling the opening and closing of the gate, at the end of the opening or closing ma-
noeuvre it also signals errors with a series of pre-defined flashes, which last for max 30 seconds.
• steady light:
• 1 flash:
Check the mains power supply, charge the battery, replace the battery.
• 3 flashes:
Check the thermal-magnetic circuit breaker (upstream from system), check the hour counter.
• 4 flashes:
Gearmotor has exceeded absorption limits, check for obstacles along the path of the over-
head door.
• 5 flashes:
Check wiring, check encoder through TEST-ENCODER (optional).
• 6 flashes:
Make sure there are no obstacles across the path of the overhead door.
• 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 continue to be signalled
until a complete opening and closing manoeuvre is executed.
