• Warranty and W arranty Restrictions

APG warrants its products to be free from defects of material and workmanship
and will, without charge, replace or repair any equipment found defective upon
inspection at its factory, provided the equipment has been returned,
transportation prepaid, within 24 months from date of shipment from factory .

THE FOREGOING WARRANTY IS IN LIEU OF AND EXCLUDES ALL OTHER
WARRANTIES NOT EXPRESSL Y SET FOR TH HEREIN, WHETHER
EXPRESSED OR IMPLIED BY OPERATION OF LAW OR OTHER WISE
INCLUDING BUT NOT LIMITED T O ANY IMPLIED WARRANTIES OF
MERCHANT ABILITY OR FITNESS FOR A PAR TICULAR PURPOSE.

No representation or warranty, express or implied, made by any sales
representative, distributor, or other agent or representative of APG which is not
specifically set forth herein shall be binding upon APG. APG shall not be liable
for any incidental or consequential damages, losses or expenses directly or
indirectly arising from the sale, handling, improper application or use of the
goods or from any other cause relating thereto and APG’s liability hereunder, in
any case, is expressly limited to the repair or replacement (at APG’s option) of
goods.

Warranty is specifically at the factory. Any on site service will be provided at
the sole expense of the Purchaser at standard field service rates.

All associated equipment must be protected by properly rated electronic/
electrical protection devices. APG shall not be liable for any damage due to
improper engineering or installation by the purchaser or third parties. Proper

• Introducing

The AGV-1000 ultrasonic collision avoidance system is designed to provide
a flexible solution for automated vehicles and other collision avoidance
applications. The system can be configured with up to six transducers
(standard), with the option of up to eight transducers for a wide coverage area.
The AGV-1000 is designed with the following features:

• Short and long range modes, each with eight programmable “SLOW” and
“STOP” functions.

• The ability to temporarily disable specific transducers to prevent
unwanted object detection.

• Adjustable random pulsing to reduce transducer cross-talk and multiple
echo interference.

• Transducer error detection circuitry, with an “ERROR” output and
programmable “SLOW” or “STOP” on error functions.

• Programmable adjustments for transmit signal strength and return signal
amplification.

• Redundant “STOP” outputs for added safety.

• RS-232 interface.

• 10 to 30 VDC operating voltage.

• Understanding Ultrasonics

Ultrasonic sensors measure distance
using a transducer to send out ultrasonic
bursts. Each burst contains a series of 1-20
pulsed sound waves that emit in the shape
of a cone, reflect off the target, and are
received by the sensor. The time required
for the sound burst to travel to and from
the target is converted into a distance
measurement by the sensor.

Ultrasonic sensing is affected by several
factors including the target surface,
distance, size, and angle. The following
considerations will help ensure the best
possible target conditions.

Surface

The ideal target surface is hard and smooth and perpendicular to the face of
the transducer. This surface will reflect a greater amount of signal than a soft,
sound wave absorbent surface. A target with poor sound wave reflection
characteristics will reduce the operating distance of the sensor and decrease its
accuracy.

AGV-1000 Rev. A3, 10/08

Distance

The shorter the distance from the sensor to an object, the stronger the
returning echo will be. Therefore, as the distance increases, the object requires
better reflective characteristics to return a sufficient echo.

Size

A large object will have a greater surface area to reflect the signal than a
small one, therefore, a large target will be detected at a greater distance than a
small target. The surface area recognized as the target is generally the portion
closest to the sensor.

Angle

The inclination of the object's surface facing the ultrasonic sensor affects the
reflectivity of the object. The portion perpendicular to the sensor returns the
echo. If the entire surface is at a great enough angle, the signal will be reflected
away from the sensor and no echo will be detected. Generally a target at an
angle greater than 5 degrees off perpendicular will not be detected.
