Product Description
The Standard PreView®is a solid-state, pulsed radar object detection
system designed to alert vehicle operators to obstacles. The sensor
detects both moving and stationary objects in a pre-defined coverage
area and can report the distance of the closest object via visual range
indicators and an audible signal to a vehicle operator. See separate
manual for display and installation guide.
The Sensor has a 1 meter harness exiting the bottom of the sensor
(details on Specifications page 7).
The Standard PreView sensor comes in two different models:
SPV 2220 Twenty (20) foot detection range
SPV 2215 Fifteen (15) foot detection range

Sensor/Antenna Description
The antenna assembly transmits and receives low power 5.8GHz radar
signals. It then processes the returned signals to determine if an object
has reflected any energy back to the sensor and reports this to the
operator display. The sensor is designed to process and report
detections within ½ of a second allowing the vehicle operator to quickly
respond to any object within the detection zone. All connections to a
vehicle are accomplished at the sensor. Power is obtained from the
vehicle reverse lights and a relay contact is provided for operating a back
up alarm. The sensor RF output is pulse modulated so that it will not
interfere with similar devices.
The Standard PreView sensor has a continuous Built In Self Test which
notifies the operator of sensor failure within a fraction of a second.
Object Detection Capability
The Standard PreView sensor can detect most objects within the
detection zone. However, there are some instances where objects can
go undetected. Obstacle size, shape, and composition are all factors
determining if, when and where an object is detected. The PreView
sensor operates by transmitting a pulse of very low power
electromagnetic energy. Any energy that strikes an object reflects a
certain amount of this energy back to the PreView sensor. This returned
energy is measured to determine an object’s distance.
The amount of energy returned is based on a few factors:
Size –a larger object usually reflects more energy
than a smaller object.
Distance –the farther away an object is, the less energy is
returned.
Composition –a metal object reflects more energy than a non-
metallic object. A metallic object at the edge of the zone will be
detected, where a wood object may not.
Scattering –a solid object reflects more energy that a non-solid
object such as wood, gravel, bushes, etc.
Angle –an object perpendicular to the sensor will reflect more
energy than an object at an angle. See next page for a detailed
explanation.
The PreView®System is designed to supplement other safety
practices and/or devices, and is not to be the sole method of
collision avoidance. The machine operator is always the first line
of defense when safely operating a vehicle.

Sensor Installation
Sensor/Antenna Location
The PreView sensor mounting location is key to proper system
operation. Ideally the sensor should be mounted on the rear as close to
the center of the vehicle as possible at roughly 36” (1M) +/- 12” (0.3M)
above the ground. The sensor face should be perpendicular to the
ground. Select a location that will provide some protection from impact
and debris while allowing an unobstructed view of the target hazard area.
Important!
Before the PreView sensor is permanently installed to the vehicle, verify
that the selected sensor mounting location provides a clear detection
zone. Temporarily attach the sensor in the proposed mounting location,
apply power to the system, and verifying that nothing is being detected.
Sensor/Antenna Mounting
1. See Installation Guide and supplied manuals.
2. Select the appropriate sensor mounting location.
3. The sensor must be mounted with the cable exit on the bottom.
4. Using the sensors’ mounting holes as a template, scribe position
marks through the holes. Drill 1/4” (6mm) holes centered at the
marks.
5. Secure the sensor to the vehicle with the three supplied 10-24 UNC
button head screws, washers and nuts or equivalent. Apply a
maximum torque of 22 inch pounds when securing the sensor.
Sensor Power Connection
Locate the vehicles reverse light power wire and connect to the red wire
on the sensor harness using 18AWG wire. Connect the black wire of the
sensor harness to vehicle ground.
Aux. Output Electrical Connection
This sensor provides access to an internal relay (white & orange sensor
wires) that can be used to activate an external backup alarm or other
device. The relay is normally open and is closed when an object is
detected. The maximum operating current is approximately 1 amp, this
includes any inrush current. For alarms or other devices that meet the 1
amp maximum current, run the device’s power or ground through the
relay. For alarms or devices that approach or exceed the 1 amp current
limit an intermediary relay must be used. Any current, including
inrush current over 1 amp will permanently damage the relay.

Safety Message to Operators of Vehicles with PreView Systems
1. The PreView system is intended as an Object Detection System and should
not be relied upon as your first line of defense for the safe operation of the
vehicle. It should be used in conjunction with established safety programs
and procedures to augment the safe operation of the vehicle, ground
personnel, and adjacent property. Should the system become inoperative, it
could jeopardize the safety or lives of those who depend on the system for
safety.
2. Testing and inspection of the system in accordance with these instructions
and record of the results should be listed on the daily maintenance report.
The units on operating vehicles must be tested each day prior to the
vehicle's operation. Results of this test must be recorded in the
maintenance log.
3. People operating this equipment MUST check for proper operation at the
beginning of every shift or safety inspection period.
4. People's lives depend on the proper installation of this product in
conformance with these instructions. It is necessary to read, understand
and follow all instructions shipped with the product.
5. Failure to follow all safety precautions and instructions may result in property
damage, serious injury, or death.
6. The PreView Object Detection System is intended for commercial use.
Proper installation of a back-up aid requires a good understanding of truck
electrical systems and procedures, along with proficiency in the installation.
7. Store these instructions in a safe place and refer to them when maintaining
and/or reinstalling the product.
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 vehicle is operating in a particularly dirty or harsh environment.
The operator has reason to suspect the system has been damaged.
This test should be performed with two people, one who remains in the cab (the
operator), and one who walks through the sensor field at the rear of the vehicle
(the assistant).
1. Clean the sensor face of any accumulation of dirt, mud, snow, ice, or debris.
2. Visually inspect the attached wiring and cable and verify that they are
properly secured, not chafing or dangling free where they could become
snagged and damaged. Inspect the Radar Sensor and Operator Display
Module and verify that they are securely attached to the vehicle.
3. Set the park brakes, start the vehicle, depress and hold the vehicle brake
and place the vehicle in reverse.
4. Verify the green “POWER” light is illuminated on the in-cab display.
5. The area to the rear of the vehicle should be clear of obstacles for a distance
of 8 meters. If the display shows any indicator other than the green light

then there are objects to the rear of the vehicle that will interfere with the
test. Move the vehicle to a clear area and proceed.
6. The assistant should move to just behind the rear corner of the vehicle in
sight of the operator's mirrors. He should then walk toward the centerline of
the vehicle parallel to the rear, while the operator notes when the display
buzzer sounds, signifying the sensor has detected the object.
7. The assistant should continue walking through the area at the rear of the
vehicle while the operator notes the area that detection occurs.
8. Next, walk from the center of the rear of the vehicle straight back, away from
the vehicle. When the display quits sounding the detection limit has been
reached.
9. Move halfway back and remain still for a few seconds, the display should
continue to sound, demonstrating the system’s ability to detect a still object.
10. The assistant should walk the complete rear of the vehicle while the operator
notes the detection edges of the entire coverage area.
11. After the test the operator and the assistant need to communicate the details
on the detection zone.
