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
problem.
1. Switch on the power supply.
2. Check the fuse (code F1)
and 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.
The door don’t finish the
distance.
1. The power regulation is low.
2. The door movement isn’t
smooth.
3. The working time is not enough.
1.
Increase
the
power
regulation VR3.
2. Unblocked the motor and
check manually if the door
movement is smooth.
3. Increase the working time in
VR1.
Remote control doesn’t
work.
1. Battery level of the remote
control is low
2. Remote control learning is not
completed
1. Change the remote control
battery
2. Re-conduct remote control
learning
Press OPEN, CLOSE
button, the gate is not
moving, motor has
noise.
1. Capacitor is broken.
2. Capacitor is poor connected.
3. Gate moving is not smoothly.
1. Change capacitor.
2. Check the capacitor wiring.
3. According to the actual
situation to adjust the motor or
the gate.
Not stop at the limit
position when opening /
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.
