Microwave Vehicle Motion Sensor
INSTALLATION INSTRUCTIONS
Section 1
General Description
The Model VPR-26 is a microprocessor-controlled vehicle sensor with a variable
range. It is designed to trigger the operation of a traffic controller. The
VPR-26 will only respond to motion in bi-direction or one direction (approach
or depart only selectable), which makes it ideal for long-range detection at
intersections. A micro- processor analyzes the reflected microwave energy and
responds to motion in the proper direction. The VPR-26 generates an extremely
low power microwave beam aimed to cover the same area normally covered by a
loop detector system. It is less expensive to install and less susceptible to
damage and malfunction from ice, salt and heavy vehicular traffic.
The VPR-26 operates on much the same principle that police radar uses. The
unit transmits a low power micro- wave signal, some of which is reflected by a
moving target, such as an automobile or truck. Larger vehicles, such as semi-
trucks, reflect more energy than automobiles and can be detected at further
distances.
Since the VPR-26 uses microwave signals as its means of detecting a moving
target, it is not affected by air motion, temperature and humidity changes, or
high frequency sounds.
Section 2
Installation
The VPR-26 vehicle sensor will perform best when it is aimed directly at
traffic. This can be accomplished by mounting the unit at the typical mounting
height of 10′ to 22′ and aiming the sensing head so it can “view” the traffic
coming toward or moving away from the unit.
The VPR-26 is mounted with 2 lag bolts through 2 – 1/2″pre-punched mounting
holes, or by banding to the poles.
To remove the fastening bracket from the sensor, take out the 5/16-18
horizontal bolt holding the bracket to the hinge. Using the bracket as a
template for locating screw holes, mark and drill the pole or band the bracket
and refasten the sensor to the bracket with the 5/16-18 bolt removed earlier.
Wiring-(see wiring diagrams below) Operating voltage is 12V to 24V AC or DC
and is usually supplied through a transformer. The current consumption of the
unit is 0.075 Amps.
NO AMPLIFIER REQUIRED!
NOTE : 24V, 24VA transformer Sold Separately
WARNING: To limit exposure to electrical damage from power surges, ALWAYS
wire the sensor through the transformer that is provided or a TCPS series
isolation module (sold separately).
Wiring of the 5-conductor cable is as follows:
To
VPR-26
Red = Power (un-fused)
Black = Power 12V to 24V AC/DC (No Polarity)
Green = Relay COM
Brown/Orange= Relay N.C.White = Relay N.O.
CONTACTS SHOWN WITH POWER APPLIED TO UNIT (FAILSAFE)
Twist counter-clockwise and pull to open waterproof housing.
Fuse = 0.5a; 250V; Fast Blo; 3AG
WARNING: Do Not ground one side of the secondary of the supply
transformer.
The circuit ground of the unit is electrically connected to the housing.
Grounding one side of the transformer may create a direct short that will blow
the fuse located in the wire harness (pictured above).
For more information, call us at
317-842-2545.
CAUTION: Do Not apply 120V AC primary power to the transformer until all
secondary wiring is complete.
Alignment
To adjust the sensor’s head angle, loosen the 5/16-18 hinge bolt. This allows
vertical movement of the VPR-26.
When alignment is complete, make sure that all bolts and screws are tightened.
Adjustment
All adjustments are made via the external controls located on the back panel
of the unit (See Figure 1).
Range Control- Allows the detection pattern to be varied to sense cars at a
maximum of 300′ and 380′ for semi-trucks and larger vehicles.
Delay Control- Allows adjustment of the relay hold time from 0.25-8.0 seconds.
Direction Switch- Allows selectable sensor detection of traffic traveling in
uni-direction or bi-direction from the sensor.
Approach/Depart Switch- Allows selectable sensor detection of traffic
traveling either towards/away from the sensor on bi-direction mode.
An LED is located at both the front and back of the unit to provide visual
confirmation that the unit is detecting traffic.
Note: Click the Reset Button each time you make changes on the Dip
Switches and Pods.
Operation
REMINDER: When power is applied, allow 30 Seconds warm-up before testing
sensor.
NOTE: This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference.
Note: The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modifications to this equipment. Such
modifications could void the user’s authority to operate the equipment.
