The battery of the board associated
with the idle leaf is discharged.
The fuse of the board associated with
the idle leaf failed.
BUS connection interrupted.
SLAVE-B battery discharged.
(The SLAVE-B board LED flashes rapidly
and LED 1 of the MASTER-B board on the
inputs status is OFF).
Discharged batteries

24 hours.
Faulty radio control
Faulty receiver board
The motor has reached the mechanical

Allow the battery to recharge until the
board's LED is on steady light.
Check
necessary, replace them.
Check integrity of the BUS connection
between the two boards.
Allow the SLAVE-B battery to recharge
until the LED is on steady light.
Check if LED P of the MASTER-B board is
OFF or flashing rapidly.
case, allow the batteries to recharge
Check the wiring as shown in the
instructions and also check if LEDs C, D
and E light correctly on the inputs status.
Check
necessary, replace them.
The radio receiver is re-activated when
mains power returns or by giving a pulse
with the key-operated selector switch; in
this case, if mains power does not return
within the next 24 hours, the receiver is
once again powered down.
Using another radio control, check if the
system is operating correctly and, if
necessary, replace the faulty radio
control.
If the automated system is still shut down
even after checking that radio control
was not faulty, replace the receiver
board.
Arrange the front and rear fittings as per
specifications.
Adjust the speed of the motors as
accurately as possible, by entering the
programming of the MASTER-B board.
closing/opening Lengthen the decelerations by fully
programming the automated system.
Check if there are any obstacles on the
route of the leaves, such as stones or
uneven asphalt, and increase the static
force of the motors.
