Gate motor beeping is a way your centurion gate motor is trying to alert you of problems. See below for what the beeping means and what possible was to resolve the problem
Three beeps: the battery is running low
This means the power supply is not charging the battery. It can either be because the power supply charging circuit is faulty or no power is supplied to the charging unit and the battery is no longer being charged. The motor may continue to run but will warn you of a potential battery-low shutdown by emitting three short beeps every couple of seconds.
Two beeps: mains failure
The majority of our gate motors are battery-driven, meaning that the primary source is either a single 12V battery or two batteries connected in series, depending on the particular model. In theory, this means that they can operate sans mains power. However, a main supply is needed in order to keep the battery in a charged state. In the event of a power failure, for example, due to load-shedding or the power supply (charger) being damaged by, say, lightning, your CENTURION gate motor will periodically emit two short beeps until power is restored.
Four beeps: multiple collisions
A “collision” in the context of gate automation can take many different forms. It could mean that the gate has picked up an actual obstruction, for example, a rock or piece of wood on the track, or it could point to some problem with the internal drive circuitry. Whatever the cause, four beeps generally mean that something has prevented the gate from completing a full opening or closing cycle, and you should refer to the LCD screen for additional information.
