The remote control does not emit any single	Check if the batteries are exhausted, replace them if necessary.
The opener doesn’t run. Power LED is OFF	1. Make sure that the power cord is properly plugged into the mains outlet. 2. Check the fuse is blown in the control board; if necessary, identify the reason for the failure and then replace a new one.
The opener doesn’t run. Power LED is ON	Make sure the photocell beam is not blocked if the photocell is used. Check the terminal 16 should be shorted with terminal 17 by a jumper wire. Please reset this jumper wire if it is loss.
The gate starts but it is immediately stop or reverse	1. The selected force is too small to move the gate. Turn the Potentiometer clock-wise to increase the force. 2. Disconnect the gate from the gate operator and check that the gate slides freely without any binding.

Trouble	Possible causes	Solutions
Motor only runs in one direction.	The wire connector terminal block becomes loose.	Check wire connector terminal block.
	The limit switch wire connector terminal block becomes loose.	Check limit switch wire connector terminal block.
		Check the limit switch mode.
By pressing button 1 (button 2 or button 3) which has been programmed to open the gate, press the same button again to stop the gate in required position, but the gate will auto-close immediately.	The auto-close time is too short.	Reset the auto-close time.
When you use button 4 of remote control to open the gate, gate travels too short.	The width of pedestrian mode is too narrow.	Reset the width of pedestrian mode.
When you use button 4 of remote control to open the gate, but the gate will auto-close immediately.	The auto-close time of pedestrian mode is too short.	Reset the auto-close time of pedestrian.
The gate will not open or close.	The limit switch wire connector terminal block becomes loose.	Check the limit switch mode.
	Connecting wires or terminal blocks are too loose.	Check the connecting wires and terminal blocks.
	The electric component on the control board such as Q6 may be damaged.	Replace the electric component Q6 or replace the board.
	Power switch is OFF	Make sure power switch is ON.
Remote control does not work	The indicator light of remote control does not light.	Check the batteries on your remote control
	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.
	Broken receive board	Replace receive board.
When you open the gate by using button 1 (button 2 or button 3) which has been programmed, gate will stop in mid-travel or reverse before reaching the fully limit position.	The Force Adj. (VR) is adjusted too small.	Check the Force Adj. (VR). Adjust VR to increase force.
	Gate is obstructed.	Remove the obstruction.
The remote control operating distance is too short.	Signals are shielded by the gate.	Link a new antenna (1-1.2m BVR 0.75mm2) to the old antenna. Then fix the antenna on the wall vertically, make sure the total height from the top of antenna to the ground is approx. 1.5m.

Aleko AS 450 gate opener troubleshooting

Problem	Cause/Solution
1. Opener does not run. Digital Display indicator is not on.	• Check if all motor are properly connected and color coded. Make sure the AC input is connected. • Check if the fuse in control board is bad.
2. Opener powers up but does not run.	• Arm cable loose or disconnected. Verify that all of the wires going to the arm are secure and that the connector is properly mated to the header. • Arm is incorrectly installed. Disconnect the motor housing from the arm and verify that the arm moves freely. • Gate is excessively heavy or hinges are bad. Verify that the gate is within the ratings for this product. Disconnect the arms and verify that both gates swing easily. Lubricate or replace hinges as necessary. • Bad control board. Call technical support for help with replacement parts.
3. Gate stops immediately after it starts moving.	• Obstruction sensed. Check safety devices and gate for obstructions. • Force set too low. Adjust FORCE setting until gate completes a full open/dose cycle without stop. The force setting may need to be adjusted in cold weather, as the gate will not move freely. • Check if the MRT period is too short. • Incorrect power.
4. Gate opens but does not close.	•Photocell (PBS) is set in Control Board but is not equipped (optional). Please cancel the PBS set. • Obstruction blocking close photo eyes, Check eyes for alignment and verify all connections and operation for safety devices.
5. Gate ignores the limit switches	• Check that the limit switch is not faulty • Check that wires to the limit switch are not shorted. • Ensure that the motor cable is away from sources of electrical interference, such as electric fences, power lines etc.
6. Gate opens, closes or stops on its own	•Ensure that the key for manual release is in the lock position.

Aleko FG300NOR gate opener troubleshooting

Symptom	Possible Solution(s)
The opener does not run. Power LED flash slowly(flash once per second).	1. Battery is over-dsiacharge. Check the voltage of the battery. The voltage of the battery should above 22V to make the gate opener work normally.

	2. Check the fuse in the control board. Replace the fuse if it was burnt out.
	3. Check the control board. Replace the control board if necessary.
Gate moves a little and then reverse or stop	1. The selected force is too small to move the gate. Turn the Potentiometer clock-wise to increase the force.
	2. Disconnect the gate from the gate operator and check that the gate slides freely without any binding.
Gate opener does not run when you press the remote control	1. Make sure the remote has been programmed to the control board before using.
	2. The battery of the remote may be exhausted. Replace the battery and try it again.
	3. Check the control board. Replace the control board if necessary.
Gate can open but does not close	1. Make sure the connection of the photocell beam is not blocked if the photocell is used.
	2. Check if the close limit switch is broken.
	3. Check the control board. Replace the control board if necessary.
Gate automatically opens, but does not automatically close	1. Setting of DIP switch #1 would be wrong. Please set the dip switch correctly according to the push/pull to opener installation of the gate opener.
