Wavetronix VDR24 Radar - Manual (Page 15)

Introduction and Overview
VDR24 Radar Detection System, Rev. 1.0 15
Using the SmartSensor-Rail Manager application, this section provides instructions on how to
configure and verify lanes, detection zones, output assignments, and operating parameters for
crossing applications. For train detection applications, track paths are established in lieu of
lanes for vehicles.
Once installed, the operational status and health of the system can be assessed by examining
performance data visible on the VDR24 controller front panel display. Many different screens
are viewable showing real-time performance parameters such as co-incident detection, radar
sensor response times, communication quality, and accumulated, historical performance
metrics.
Section 9: Support, Maintenance, Troubleshooting
This section provides information on maintenance and how to obtain troubleshooting assistance
and user support. The Island Radar Company provides knowledgeable and experienced
support through its field support resources, which is available for assistance 24 hours per day.
Section 10: Additional Installation or Site Information
This section provides special notes or information on equipment modifications unique to a
particular application.

Term Description
Attenuation Designated in unitless decibels (dB), attenuation is a relative
decrease in sensitivity, Lower attenuation means greater
sensitivity while higher attenuation means less sensitivity.
AREMA The American Railway Engineering and Maintenance-of-Way
Association (AREMA) is a North American railway industry
group. It publishes recommended practices for the design,
construction and maintenance of railway infrastructure, which
are requirements in the United States and Canada.
Channels For the purposes of the Island Radar detection system, Output
Channels are the isolated interface point between Detection
Zones and Railroad equipment. See Lanes and Zones.
Clear Storage Distance The six-foot minimum space between the outermost rails and
a lowered entrance or exit gate at a grade crossing.
Closed Contacts For the purposes of the Island Radar detection system, a
closed contact is an isolated, solid state, electrical switch that
establishes a connection and conducts current.
Crossing Island The area bounded by entrance and exit gates at a grade
crossing through which a roadway passes.
Crossovers or Interlockers A switchless interface between two or more tracks. For the
purposes of the Island Radar detection system, a crossover is
