Hello. Over time, the start and stop limits on all gate openers and garage door openers need to be slightly adjusted. What is happening to your gate is this. The limit which closes the gate is actually closing it a wee bit too much. By simply turning the down or close screw about 1/4 turn you will solve the problem. Joe

New FM502 Dual gate opener pressed remote which starts the second gate opening then the master moves a few inches stops. Hear 3 beeps 2 seconds 3-. .Conections are good to circuit board! What up!


reprogram the opening sequence in the control box
it should that the first gate opens then the second gate opens a few seconds behind it
closing is the reverse
you can program that only one gate opens
you can also program that one gate is a entrance gate where it opens until you stop it , then when you have passed through , press it again and it closes
read the operating instructions and follow the programming procedures closely

Gemini gate motor


Check if it has stops anywhere in the system, usually there are micro switches that are activated by arms, etc that tell it how far to open and close. You may need to adjust them.

Linear SWR-211 gate opened and got stuck when it tried to close. Tried reset and shut power off. Still stuck in half open position.


So the gate is stuck in a half open position? If you have already tried resetting it, you might just need to call in someone from the company. Some gates have an emergency retract option. You can look for that, at least it wouldn't be just half open.
