25 K126MA
5 (red) flashes:
max current limit for motor 1 exceeded;
Excessive absorption peaks of the gearmotor, check there are
no obstacles on the automation path, check the current absorp-
tion of the motor when in a no-load condition and when applied
to the gate,
5 (yellow) flashes:
max current limit for motor 2 exceeded (in case of failure of
motor 1 wire terminal and with dip # 10 set in ON);
Excessive absorption peaks of the gearmotor, check there are
no obstacles on the automation path, check the current absorp-
tion of the motor when in a no-load condition and when applied
to the gate
6 flashes (red):
auto-close failed after 5 unsuccessful attempts;
A command input is necessary to perform closing operation;
6 flashes (yellow):
master/slave communication error;
Check wiring between the controllers, efficiency of slave con -
troller (fuses), efficiency of interface boards;
8 (red) flashes: Eeprom external memory fault;
Replace the external memory module;
8 (yellow) flashes: Eeprom data error (internal/external);
Perform procedure RADIO MEMORY RESET;
Apart from the logic mistakes, the DL8 LED indicates also the status of the control unit during the
saving of the radio controls.
always on (green): channel CH1 waiting to be saved;
fast flashing (green):
CH1 channel memory full;
always on (yellow):
channel CH2 waiting to be saved;
fast flashing (yellow):
CH2 channel memory full;
flashing (green):
CH1 channel waiting to be cancelled;
always on (green): cancelling of channel CH1 in progress;
flashing (yellow): CH2 channel waiting to be cancelled;
always on (yellow):
cancelling of channel CH2 in progress;
When LEDs DL7 and DL8 flash at the same time they indicate:
flashing + (red + red):
factory reset procedure waiting for confirmation;
flashing + ( yellow):
waiting for total cancellation of the radio channels;
Multiple errors are signalled by a 2-second pause between signals.
Should the encoder (obstacle detection) activates while closing, the controller will reverse the direction
and slowly open until the laef reaches its fully opened position. Auto Close function will be deactivated
until a further command pulse is given. In case of 5 consecutive safety interventions the controller will
progressively increase the Auto Close delay. Once the closing has been succesfully achieved, the Auto
Close delay will go back to standard setting.
ABSORPTION CHECK FUNCTION (from 5.17 release onwards)
This function allows to monitor the absorption during a complete cycle in order to value the motor stress.
To activate this function press and hold for 2 seconds simultaneously CH1, PROG, CH2 and them start
the motor (OP/CL contact, remote, PROG button).
