Why doesn't the barrier gate automatically lower after being raised?
2 Answers
If the barrier gate doesn't automatically lower after being raised, it may be due to aging. Here are some precautions for using a car engine: Avoid driving in neutral gear: The engine itself has a fuel-cut function during deceleration, and driving in neutral is actually less fuel-efficient. Pay attention to observation when using the vehicle: If you notice oil stains on the ground, determine whether there's an engine oil leak and promptly communicate with the car 4S store to eliminate potential safety hazards. Don't turn off the engine immediately: For cars equipped with turbochargers, avoid turning off the engine immediately after high-speed driving or climbing slopes. Let it idle for 10 minutes before shutting down. Cars with turbochargers accumulate carbon deposits several times faster than naturally aspirated cars.
I've encountered the issue of the barrier gate not automatically lowering after being raised several times. Usually, it's because the vehicle detection sensor is malfunctioning—perhaps it's too dirty or broken—which makes the system think a car is still underneath. I've tried cleaning the induction area on the ground with a clean cloth, and sometimes that fixes the problem. Additionally, a stuck control board or motor could also cause this issue, so it's necessary to check if the wiring is loose or if a fuse has blown. For smart barrier gate systems, a software bug might prevent the gate from lowering, in which case restarting the control box or having a technician update the firmware can help. Remember to manually check if the gate lowers properly after each use and don't overlook small details. Leaving it unrepaired for a long time might allow unauthorized access, increasing security risks. I think it's best to perform regular cleaning and simple maintenance to avoid unexpected malfunctions affecting daily operations.
