Troubleshooting

Have a multimeter to check voltage and continuity. Use caution when checking high voltage terminals.
Symptom
The opener does not
run. Power LED is
OFF.
The opener does not
run. Power LED is
ON.
Remote control does
not work.
The gate starts but it
is immediately stop or
reverse
The gate opens, but
stops and will not
return.
1. Make sure that the power cord is properly plugged into the mains outlet.
2. Check if the output voltage of the transformer is 24VAC. If the voltage
measures 0, the transformer may be overheated or damaged. Turn power off
and allow board to cool for several minutes then reset. Replace the
transformer if the symptom still exists.
3. Check the fuse in the control board. Replace the fuse if it was burnt out.
4. Check the control board. Replace the control board if necessary.
1. Check to be sure the beam is not blocked if a photocell is used as a
secondary entrapment prevention device. If a photocell is not used, terminal
8 should be shorted with terminal 9 by a jumper wire.
2. Check the motor. Release the clutch then disconnect the wires of the
motor from terminal 1 and 2. Connect the wires to the terminal 16 and 17
directly, the motor should run, and then exchange the wires, the motor should
run in the opposite direction. If the motor runs in both directions, please
check the other parts listed below.
3. Check the limit switches. Use a jumper wire to short terminal 4 with
terminal 3 and 5, and then use a keying device to operate the opener, replace
the higher limit switch if the motor couldn't run in clockwise direction, and
replace the lower limit switch if the motor couldn't run in counter-clockwise
direction.
4. Replace the control board if the motor runs in all steps above.
1. The indicator light of remote control is not on. Check the battery in your
remote control. Replace the battery if necessary.
2. The distance you use the remote is too far away from the opener. Try it
again closer.
3. Remote control is not suitable for receiver. After making sure the codes are
correct, erase remote controls and then re-program the codes in the device.
4. Replace the control board.
1. Check that the clutch is adjusted properly and is not slipping.
2. The opening force or closing force is adjusted too small. Turn the
Potentiometer A to increase the force.
3. Disconnect the gate from the gate opener and check that the gate slides
freely without any binding.
4. Replace the control board.
1. Please note the two magnet brackets (fixed plate) are different: one is
higher and another is lower. Please try to exchange the two brackets
position.
2. Please try to exchange the limit switch wires CL (close) and OP (open).
