Gate Does not Move at all (three short beeps)

Gate Does not Move at all (three short beeps)

Possible causes: 

Poor connection between battery and controller

The battery voltage is low or the battery is faulty or disconnected

There is no mains power to the motor

Faulty controller 


Possible solutions: 

Ensure that the battery terminals are properly connected on both the controller and battery side

Measure the battery voltage – it should be no lower than 11V DC when placed under load.

Check for corrosive build-up around the battery terminals. If there is corrosion, replace both the battery and terminals

Replace the battery

Measure the onboard charger’s output voltage. It should be about 14V DC

Ensure that the safety PE beams are in working order

Replace controller
