Overlength Sensors – What are they?
When you use one of our automated parking machines, you might occasionally see a warning like “Vehicle Overlength — Please Reposition Your Vehicle” on the screen or a blinking light at the front of the machine. This is thanks to an important safety feature: the overlength sensors. So, what are they? Overlength sensors are photoelectric (photoeye) sensors located at the front and rear corners of the parking platform — four in total, one at each corner. Their job is to make sure your vehicle is parked properly within the designated clearance area of the platform. If your vehicle is parked too far forward or too far back, it will block one or more of the overlength sensors. When this happens: On most generations of machines, the control panel may also display a Code 4, which indicates an overlength error. How to resolve an overlength error? ✅ Return to your vehicle and adjust its position so it sits correctly between the front and rear limits of the platform.✅ Check that the blinking light has stopped.✅ Return to the kiosk or RUIS display, and press Continue to proceed.✅ If the system is equipped with a RUIS display, the overlength message will also disappear when the vehicle is properly positioned. These sensors are critical for the safety and reliability of the parking machine, ensuring no vehicle overhangs into areas that could cause damage or interfere with the system’s operation. Next time you see the overlength warning, just reposition your car, and you’ll be good to go!
