The reasons for the barrier gate not lowering include the triple button being set to manual mode, the ground sense processor of the barrier gate crashing, issues with the ground sense coil, failure of the barrier gate's mainboard, or interference from other peripherals. Below are the detailed explanations: 1. Measures: Set the triple button to automatic mode; check if the OUTPUT indicator light on the ground sense processor of the barrier gate is flashing green rapidly; restart the barrier gate's power supply to see if it returns to normal. If not, replace the ground sense processor, measure the continuity of the ground sense coil; replace the barrier gate's mainboard for testing; disconnect and test the wiring to the card reader. 2. No response when the card reader is powered on: Check the two power supplies (12V and 24V) separately, see if the power indicator light on the card reader's mainboard is lit, and check for any burned or overheating electronic components.

The issue of the barrier gate not lowering is quite common in my daily experience. It could be due to problems with the motor system, such as a burnt-out or jammed motor, or dust accumulation in the mechanical structure causing poor operation. Controller malfunctions are also a key factor—sensors might fail to detect a vehicle leaving, mistakenly identifying it as an obstacle, or software settings could be incorrect, disrupting signals. Power issues, like unstable voltage or outages, naturally prevent the gate from moving. Additionally, in winter, ice buildup on the gate head or foreign objects getting stuck can also cause jams. I recommend not forcing your way through when encountering this issue—safety first. First, observe if there are any unusual noises or vibrations from the gate, then contact management for inspection. Regular maintenance, like cleaning sensors and lubricating moving parts, can extend equipment life and avoid parking disputes.

When I was driving a taxi, it was quite common for the barrier gate not to lower. The most annoying issue was sensor failure, possibly due to water damage or aging, which failed to detect the car leaving and automatically rise. There were also button operation problems, like the administrator forgetting to press the switch or setting errors. Mechanical failures were frequent too, such as the gate arm getting stuck in position and not lowering, or power cord loosening causing a power outage. Rainy or snowy weather often caused trouble, with mud covering the probes. In such cases, I usually turned on the hazard lights and stopped for a moment, waiting a few seconds to observe the situation. If that didn’t work, I’d call the customer service hotline for help. In the long run, installing high-quality components and regular maintenance can reduce such hassles. I’d like to remind community members to pay attention to gate safety.

There are many reasons why a barrier gate may not lower: the motor is burned out or stuck and cannot rotate; the sensor is malfunctioning and fails to detect vehicles accurately; the controller is abnormal, causing signal errors; power supply issues, such as broken wires or low voltage; mechanical parts are jammed, blocked by debris. If encountered, simply check the buttons and whether the lights are on, and if not, notify for repairs. For safety, do not force passage and handle the situation patiently.
