Product Description The PreView Side Defender®II is the FMCW radar included in the Side Defender®II object detection system that is designed to alert drivers of medium and heavy-duty vehicles or obstacles and vulnerable road users in their side blind zone. The Side Defender®II has intelligent modes of operation to minimize false alerts due to stationary objects such as guardrails and parked cars, while still providing reliable alerts when moving bicycles and other vehicles are in the detection zone.
Using frequency modulated transmit waveform (FMCW) technology, the Side Defender®II radar measures radial range, speed, angle, reflectivity, and other parameters of multiple stationary and moving targets simultaneously. This radar sensor has a wide horizontal field of view up to +/-75°, optimized for side object detection in large trucks and busses. The horizontal field-of-view is approximately 39 feet (12 m) along the vehicle side and extends approximately 10 feet (3 m) from the side of the vehicle.
Sensor Interfaces and Configuration Incorrectly connecting to a vehicle CAN bus can cause erratic and dangerous vehicle behavior. Do not connect the PreView Side Defender®II sensor directly to the vehicle CAN bus. Always use a gateway such as the PreView D2002 display designed to ensure the connection allows one-way communication only from the vehicle CAN bus to the PreView Side Defender®II. Do not allow PreView Side Defender®II J1939 messages to be transmitted on the vehicle CAN bus.
System Connections Locate the vehicle’s ignition power and connect to the red wire on the body harness. If it is necessary to extend the power wire on the supplied harness, use 20 AWG wire as a minimum. Locate the vehicle’s turn signal wire associated with the turn signal on the sensor side and connect to the blue wire on the body harness. Be sure that the turn signal wire selected activates ONLY when the turn signal is active and is the operational (not diagnostic) signal.
Object Detection Capability The PreView Side Defender®II is a blind spot collision warning system designed to supplement other safety practices and/or devices. The vehicle operator is always the first line of defense when safely operating a vehicle. The PreView Side Defender®II can detect most objects within the detection zone. However, there are some instances where objects can go undetected.
The amount of energy returned is based on a few factors: Size – a larger object usually reflects more energy than a smaller object. Composition – a metal object typically reflects more energy than a non-metallic object. Scattering – a solid object reflects more energy than a non-solid object such as tree branches, gravel, bushes, etc. Shape – complex shapes cause energy to be returned in a very non-uniform way. Small variations or movement can change detection status.
System Operation The Side Defender®II system is designed to ignore stationary objects such as guardrails and parked cars while alerting on moving objects such as bicyclists and moving vehicles in the adjacent lane. The detection zone for the Side Defender®II when the vehicle is stationary is 5 m fore and 5 m aft of the sensor out to 3 m from the side of the vehicle. When in motion, the detection zone expands to 6 m fore and 6 m aft of the sensor out to 3 m from the side.
Sensor Installation Before you Begin Prior to installing the PreView® Object Detection System take time to familiarize yourself with all of the all documentation, theory of operation, and system components. Sensor Location The Side Defender®II mounting location is IMPORTANT for proper system operation. The sensor should be mounted on the side of the vehicle with the bottom of the radar no lower than 23” (60 cm) and the top of the radar no more than 39” (1 m) above the ground and between 137” (3.
Sensor Mounting 1. Select the appropriate location to mount the sensor (see Figure 5). 2. The standard mounting configuration is with ‘Side Defender®’ text up, as shown in Figure 1. 3. Using the drill template, scribe position marks through the holes. Drill 1/4” (6 mm) holes centered on the marks. 4. For the pigtail, drill a 1 1/2” (38 mm) hole for the sensor connector and mating connector. 5. Secure the sensor to the equipment using the supplied hardware, with a maximum 22 in-lbs (2.5N-m) torque.
Mounting Tolerances For optimal performance, the vertical angle (up/down) tolerances are +5° (up) and -2° (down). The horizontal angle (side/side) tolerance is +/- 2° and the fore/aft angle tolerance is +/- 2°. Figure 6 - Vertical and Horizontal Angle Mounting Tolerances The performance of the sensor can be negatively impacted if the sensor is angled down, causing ground and curb detections. Any time the sensor is not perpendicular to the ground, the performance should be tested.
Keep Out/Interference Zones Metallic and other strong radar reflecting objects must remain outside of the Keep Out Zones defined in Figure 7. Radar reflecting objects within these areas may affect operation. If those objects cannot be removed, testing must be performed to determine the influence on the system’s performance.
PreView® Daily Maintenance Safety Message to Vehicle Operators with PreView® Radar Systems 1. Failure to follow all safety precautions and instructions may result in property damage, serious injury, or death. It is necessary to read, understand and follow all instructions shipped with the product. 2. Systems on operating equipment must be tested each day prior to the equipment operation. The equipment operator must check for proper operation at the beginning of every shift or safety inspection period. 3.
Testing and Maintenance NOTE: A walk around test shall be performed every day to verify proper function of the system and to familiarize the operator with the zone of detection. More frequent inspections should be performed when: • • The equipment is operating in a particularly dirty or harsh environment. The operator has reason to suspect the system has been damaged.
