1. INTRODUCTION

The PD130 Enhanced Vehicle Detector is a single channel microprocessor based detector designed

specifically for parking and vehicle access control applications. The PD130 Enhanced Vehicle

Detector has been designed using the most up-to-date technology in order to meet the requirements

of a vast number of parking applications (in terms of operating conditions and options available to the

user.)

The primary function of the detector is to detect vehicle presence by means of an inductance change,

caused by the vehicle passing over a wire loop buried under the road surface.

The detector has been designed for ease of installation and convenience. The various modes are

selected by changing the positions of the switch on the front of the unit.

The switches allow for different loop frequency settings, sensitivity settings and mode settings.

The PD130 Enhanced Vehicle Detector provides visual output (LED) on the front of the enclosure and

relay change-over contacts are taken on the 11 pin connector at the rear of the enclosure. The LED

indicates the power has been applied to the unit, that a vehicle is present over the loop and if there is

a fault on the loop. The Presence relay is fail-safe and will close on a vehicle detect or in the event of

power failure or a loop fault.
