Troubleshooting
Problems
The gate cannot open or close normally,
and LED does not light.
The gate can open but cannot close
Remote control doesn't work
Press OPEN, CLOSE button, the
gate is not moving, motor has
noise
Not stop at the limit position when
opening / closing
Leakage switch tripped.
Remote control working distance
is too short.

Opening your life
Possible reasons
1) The power is o .
2) Fuse is burned.
3) Control board power wiring with
problem
1) Photocell wiring with problem
2) Photocell mounting with problem
3) Photocell is blocked by objects
4) Auto-reverse force is too small
1) Battery level of the remote control is
low
2) Remote control learning is not
completed
1) Capacitor is broken
2) Capacitor is poor connected
3) Gate moving is not smoothly
1) The limit direction is wrong.
2) The mounting of magnetic limit
switch with problem
Power supply line short circuit or
motor line short circuit
Signal is blocked
1) Motor output force is not enough
(Intelligent type).
2) Gate meets obstacle
Automatic close function has been
turned on but with incorrect opening
direction

Solutions
1) Switch on the power supply.
2) Check the fuse (code FU1), change the fuse if burnt.
3) Re wiring according to instructions
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
1) Change the remote control battery
2) Re-conduct remote control learning
1) Change capacitor.
2) Check the capacitor wiring
3) According to the actual situation to adjust the motor or
the gate
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
Check wiring
Connect external receiver antenna, 1.5 meters above
ground
1) Adjust the VR2
2) Adjust the VR3
3) Remove the obstacle
Please refer to the attentions under 4.3.5 to change the
opening direction
