Vehicle Detector Loop Detector To Sense Vehicle Inspection Device Traffic Inductive Signal Control PD132

Introduction

The detector must be installed in a convenient weatherproof location as close to the loop as possible. Installation

location must choose to stay away from the heat source; it around other devices must maintain a distance of at least

10mm (must not installation close with boxes wall). A correct loop configuration and detector installation will ensure a

successful inductive loop detection system. Loop of several important parameters include: loop figure, size, turns, install methods.

Operation and Indication
While the detector is tuning, the green Channel LED and red Power LED will be turn on. It remain about 2 seconds,

then the green LED turn off. If a loop fault exists the Channel LED will come on and flash indicating a fault. If the fault

is self-healing the detector will continue to operate. The green channel LED will also glow whenever a vehicle is detected

passing over the inductive loop. The red Power LED at the top of the unit will remain on to indicate that the unit is powered.

Main Features:

1) Reset Switch : The reset switch enables the detector to be manually reset during commissioning and testing .

This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection ;

2) Selectable Pulse Time : This feature sets the length of time that the pulse relay will be energized for 1 Second

or 0.5 Seconds ;

3) Pulse Relay Selection : The Pulse Relay may be configured to energize on detection of a vehicle or when the

vehicle leaves the loop ;

4) Sensitivity Boost : This feature sets the undetect level to maximum sensitivity and is used to prevent loss of

detection of high-bed vehicles ;

5) Switch Selectable Sensibility : 4 sensitivity setting are available on the switches to allow flexibility in configuration ;

6) Switch Selectable Frequency : 4 frequency settings are available to prevent cross-talk between adjacent loops ;

7) Filter Option : This option is used to provide a delay between detection of the vehicle and switchiing of the output relay.

This relay is normally used to prevent false detection of small or fast moving objects ;

8) Permanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is parked

over the loop for extended periods .
