Problems
Possible Reasons
Solutions
The gate cannot open or
close normally, and LED
does not light.
1.The power is off.
2.Fuse is burned.
3.Control board power wiring with

transformer input interface fuse,
change the fuse if burnt.
3.Re wiring according to
instructions.
The gate can open but
cannot close.
1.Photocell wiring with problem.
2.Photocell mounting with problem.
3.Photocell is blocked by objects.
4.Auto-reverse force is too small.
1.If not connect photocell, please
make sure that the infrared port
and GND short circuit; if connect
infrared sensor, please make sure
the wiring is correct and the
photocell is N.C.
2.Make sure that the photocell
mounting position can be mutually
aligned.
3.Remove the obstacle.
4.Increase auto-reverse force.
Remote control doesn’t

1.Battery level of the remote
control is low
2.Remote control learning is not

closing.
1. The limit direction is wrong.
2. The mounting of magnetic limit
switch with problem.
1.Check whether the limit switch
wiring is consistent with the actual
direction of operation.
2. Check whether the distance
between magnetic limit switch and
motor, and the height of the
magnetic limit switch can meet the
mounting requirement.
Leakage switch tripped.
Power supply line short circuit or
motor line short circuit.
Check wiring.
Remote control working
distance is too short.
