Common causes include power supply issues, blown fuse, loose wiring, worn electromagnet, or limit switch misadjustment. BOV uses industrial-grade ARM control and brushless anti‑collision motors with built‑in self‑test and fault codes. We design robust drop‑rod mechanisms and provide detailed commissioning & maintenance guides to reduce “won’t rotate” and “unexpected arm drop” failures.

Traditional tripods often let multiple people pass on one credential if the mechanical lock and logic are not strict. BOV integrates precise one‑person‑one‑rod mechanical design with tailgating alarms and optional access control / ticketing system. We tune unlocking logic and sensor timing to minimize tailgating while keeping throughput high.
