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.

3. OPERATING PROCEDURE

3.1 Hardware Set-Up

The PD130 Enhanced Vehicle single channel parking detector is designed to be shelf or DIN rail
mounted, with the controls and visual indicators at the front, and wiring at the rear of the enclosure.

The power, loop and relay outputs are all connected to the single 11-pin plug, which is mounted at the
rear of the enclosure.

3.2 Switch Setting Selections

3.2.1 Frequency Switch

The frequency switches are the lower two switches, switches No. 1 and 2. There are four frequency
selections:

SW2 SW1
Off Off High
On Off Medium-High
Off On Medium-Low
On On Low

The frequency switches allows the operating frequency of the loop to be shifted higher or lower
depending on the switch position. The frequency of the loop is determined by the loop size, and the
frequency of the switch simply causes a frequency shift on the loop.

Where more than one detector is used the detectors must be set-up to ensure that there is no cross­talk (interference) between the detectors. This can be achieved by ensuring that the loops of the two
detectors are spaced sufficiently apart (approximately 2 metres between adjacent edges) and also
ensuring that the detectors are set to different frequencies. As a general rule, the detector connected
to the inductive loop with the greatest inductance should be set to operate at the lowest frequency.
Loop inductance increases as loop size, number of turns in the loop and feeder length increases.
