Problems
Possible reasons
Solutions
The gate can open but cannot close
1) Photocell wiring with problem
2) Photocell mounting with problem
3) Photocell is blocked by objects
4) Sensitivity of obstacle is too high
(Intelligent type).
5) Hall switch parts is damaged
(Intelligent type).
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) Reduce the sensitivity of obstacle
5) Change hall switch parts
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 reach up 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.
Signal is blocked
Connect external receiver antenna, 1.5 meters above
ground
The gate moves to the middle
position to stop or reverse
1) Motor output force is not enough
(Intelligent type).
2) .Sensitivity of obstacle is too big
(Intelligent type)
3) Gate meets obstacle
1) Adjust the VR2
2) Adjust the VR3
3) Remove the obstacle
Troubleshooting
Gate opens automatically
Automatic close function has been
turned on but with incorrect opening
direction
Please refer to the attentions under 4.3.5 to change the
opening direction
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 FU1), change the fuse if burnt.
3) Re wiring according to instructions
