Fault
Possible causes
Solution
Automated system shut down.
MASTER-T and SLAVE-T board LED P OFF
No mains power supplied to both
MASTER-T boar and SLAVE-T board.
The gate will stay locked until mains
power returns.
STOP (3) and FSW (4 and 5) terminals not
connected.
Check the wiring as shown in the
instructions and also check if LEDs C, D
and E light correctly on the inputs status.
Automated system shut down.
Automated system shut down. It does
not move by any command (radio
control or key operated selector switch),
but LED P is ON.
Fuse
failed.
Check the fuses (F20A) and, if
necessary, replace them.
BUS connection interrupted.
(LED P slow flashing)
Check for integrity of BUS connection
between the two boars (see Fig. 8)
Only the leaf associated with the
MASTER-T board is moving, while the
SLAVE-T board leaf is not moving.
No mains power supplied to the SLAVE-T
board.
(LED P fixed ON)
Check for integrity of mains power
supply connection (see Fig. 8).
Faulty radio control
Using another radio control, check if the
system is operating correctly and, if
necessary, replace the faulty radio
control.
Automated system shut down.
Moves only by key-operated command.
Faulty receiver card
If the automated system is still shut down
even after checking that radio control
was not faulty, replace the receiver
card.
The automated system jams and/or
jerks strangely on starting.
The motor has reached the mechanical
travel limit.
Arrange the front and rear fittings as per
specifications.
The leaves swing wildly at the start of
their manoeuvre or when moving.
Speed of motors inadequate for gate.
Adjust the speed of the motors as
accurately as possible, by entering the
programming of the MASTER-T board.
Gate reaching the mechanical travel
stops at full speed and reversing motion.
Insufficient closing/opening
decelerations
Lengthen the decelerations by fully
programming the automated system.
Force too low (meeting an imaginary
obstacle)
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.
During movement, the automated
system reverses motion for no reason.
Incorrect reading of Domo motor
movement.
Make sure that the motor power cable
was not extended or modified.
