Remotes fail to learn. What do I do?
1. Check battery of the remote is exhausted.
2. When the LED displays “L n”. Press the key in the remote two or more times within 2 seconds while learning. (The remote will fail to learn as soon as the interval between two pressing is longer than 2 seconds)
3. Contact local dealer to request a short video about remote programming to double check.
Both the actuators don’t work. Motors don’t run. LED flashes ”－ －” when I operate the push button or wired keypad. How do I solve this?
Use a jumper wire to short the O/S/C terminal temporarily to operate the gate opener. If the gate works, re-connect the push button and wired keypad or replace them with a new one.
Is the control board defective in most situations when the gate opener does not work correctly or not at all?
In our experience, most trouble or failures can be attributed to incorrectly installed or programmed equipment. Don’t think the control board has been defective and/or require replacing before you check and try to solve the problem. Sometimes what you should to do is re-set or re-program the unit.
Why is the wire of limit switch near motor (open limit switch) too short to adjust?
The switch near the motor is fixed in a factory position; it is non-adjustable in our design.
In “Pull to Open” installation, we don’t suggest the user to adjust the open limit position since the desired gate open angle can be determined by installing the post brackets, pivot brackets and gate brackets.
In the beginning, the user should use a fully retracted actuator to determine the gate open position. Then extend the arm towards the gate closed position. Slide the limit switch which is farthest from the motor to adjust the gate in desired close position.
Which do I select? “Pull to Open” or “Push to open”?
Answer: It is strongly recommend selecting “Pull to open”. The “Push to Open” option is used only for gates installed on upward slope to “towards” your property.
Warning: Swing gates shouldn’t open toward to public area when the“Pull to Open”is selected.
