Roll Over Sensor ROS1224
THE ROLL-OVER SENSOR The REDARC Rollover Sensor (ROS) represents a significant improvement over the existing rollover sensors in the market. It enables trucks to meet the roll-over sensing requirements of AS2809:2008, signalling the isolation switch to disconnect power to the truck system in the event of a truck rollover. It has been designed for high reliability, undergoing thorough environmental and lifetime testing.

OUTPUT 5 Isolation switch control output. Switches to TRIGGER ground on rollover. Redarc BMIS 6 Trigger enable for Redarc BMIS Trigger enable VIN8 Ground connection for electronics. Do not connect other pins: they are reserved for future use.
2 FUNCTION 2.1 On-board LED Indicator and optional Dash Warning Lamp An LED on the unit and Dash warning lamp (optional) indicates the status of the ROS. During normal operation of the ROS, the on-board LED will be on solid and the dash lamp will be off. If there is a fault with the ROS or associated wiring, the on-board LED will flash and the dash warning lamp will be on solid.
2 FUNCTION 2.2 Periodic Testing The requirements of AS2809 state that the roll over switch must be tested periodically. For maximum safety, the REDARC ROS is designed to be tested by physically moving the ROS, simulating a vehicle rollover. Test procedure: Ensure the vehicle is stationary and level with the engine off, park brake on, and isolation switch on (ROS must be powered for at least 15 seconds) 1. Loosen the security screw, remove pin. 2.
3 INSTALLATION 3.1 Mounting Detail Must be mounted in a flat, level location. The accuracy of the level mounting will directly affect the accuracy of the switching angle. Mounting direction should be with the connector in line of the vehicle (pointing front or rear) with the label facing upwards to make Tilt testing easier. Recommendations: • Mount in a location protected from debris/ impact • Do not mount near exhaust or other extreme heat sources • Mount away from fueling points.
