Redarc ROS Bedienungsanleitung
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.
The REDARC ROS has been designed for easy periodic testing with a simple pin-removal and tilt
mechanism featuring retained pins to prevent them being lost.
WARNINGS & SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - This manual contains IMPORTANT SAFETY INSTRUCTIONS for the ROS.
DO NOT OPERATE THE ROLL OVER SWITCH UNLESS YOU HAVE READ AND UNDERSTOOD THIS MANUAL AND THE ROLL
OVER SWITCH IS INSTALLED AS PER THESE INSTALLATION INSTRUCTIONS.
1. ALWAYS SECURELY MOUNT THE ROS ON A FLAT, HORIZONTAL SURFACE. FAILURE TO CORRECTLY MOUNT THE ROS
MAY RESULT IN HAZARDOUS SITUATIONS DUE TO UNEXPECTED OPERATION.
2. USE APPROPRIATE FUSES TO PREVENT FIRE IN CASE OF DAMAGED WIRING.
1. DO NOT TEST THE ROS WHILE THE ENGINE IS RUNNING. THIS MAY CAUSE DAMAGE TO OTHER ELECTRICAL SYSTEMS
ON THE VEHICLE.
2. WIRE ONLY ACCORDING TO AN APPROVED REDARC WIRING DIAGRAM.
FEATURES
• Easy periodic test by pin-removal and tilt mechanism

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.
The following are causes for Fault indication :
• Failure to return unit to level condition following a tilt test
• Connection between ROS and isolation switch lost
• High ambient or internal temperature
• Internal accelerometer failure
• Internal self test fail
If the ROS is left at an angle greater than 10 degrees due to not being locked down after
testing, the ROS will indicate a fault.
Once the fault has been rectified by locking down the ROS flat into its base, the ROS must
have power disconnected and reconnected to clear the fault.
On first power up the ROS will turn the dash warning lamp on for 10 seconds, it will then
turn off.
The dash warning must be a low-current LED lamp suitable for 12 or 24V systems

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. Tilt the ROS until it hits the stop,wait 3 seconds and ensure that the batteries have
been isolated. The ROS on-board LED should be off now. If the batteries do not
isolate, refer to the troubleshooting guide.
3. Return the ROS to the correct flat position, return the pin and security screw. Re-
connect the isolation switch by turning the handle or as per switch instructions.
4. Repeat steps 1 - 3, except lift the other side. Upon completion, double check that
the ROS is fastened properly.

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.
• Check and ensure that the connection cable is supported yet flexible enough to
allow rotation motion during tilt testing
