What is the problem if the barrier gate does not lift the bar?
1 Answers
Barrier gate not lifting the bar is caused by issues with the vehicle detector, limit switch, card access permission, or control wiring. Vehicle Detector: Check if the vehicle detector's green light is constantly on. If it is, unplug the vehicle detector and then try the remote control manual switch. If it's not functioning properly, replace the vehicle detector. Limit Switch: Manually rotate the handle clockwise to see if it can still turn. If not, rotate it counterclockwise for two turns and then try the remote control again. If the remote control can lift the bar, it means the limit switch's rotation count is too small. After lowering the bar, rotate the handle on the motor counterclockwise for one and a half turns and adjust the limit switch until the indicator light comes on. Card Access Permission: Swipe the card and observe if the relay on the system control board jumps. If it does not jump, the card has no permission. Reissue the card with the necessary permission. Control Wiring: Check the wiring from the control board to the barrier gate board for the lift line and the vehicle detector wiring. If the wiring is correct, the issue might be that the card has no permission or the control board parameters were not restarted after loading.
