Product Description
AC220V 170kHz Car Parking Loop Detector PD232 Double Channel CDMA
Standard Double Channel CE Certificate Car Parking Vehicle Loop Detector PD232
Product Introduction
This dual microprocessor-based loop detector is specifically designed for parking and vehicle access control applications. Its primary function is to detect vehicle presence through inductance changes caused by vehicles passing over a wire loop buried under the road surface.
Installation & User Guide
The detector must be installed in a convenient weatherproof location as close to the loop as possible.
WARNING:
1) Installation and operation by service personnel only
2) Disconnect power before working on this unit

A correct loop configuration and detector installation will ensure a successful inductive loop detection system.
Operational Constraints
Crosstalk
When two loop configurations are in close proximity, magnetic field overlap can cause false detects and detector lock-up. Crosstalk can be eliminated by:
- Careful choice of operating frequency - closer loops require further apart frequencies
- Maintaining minimum spacing of 7 feet between loops where possible
- Careful shielding of feeder cables if routed with other electrical cables, with shield earthed at detector end only
Reinforcing
Reinforced steel below road surface reduces inductance and sensitivity. In this case, add two additional turns of wire to the loop. Ideal spacing between loop cable and steel reinforcing is 6 inches. Keep slot depth as shallow as possible, ensuring no part of the loop or feeder remains exposed after sealing compound application.
Installation Information
Loop and Feeder Specification
- Loop must consist of insulated wire with minimum copper cross-sectional area of 1.5 square millimeters
- Feeder should be same material, twisted minimum 20 twists per meter
- Joints in loop or feeder are not recommended - if necessary, solder and terminate in waterproof junction box
- For long feeders or routing with other electrical wiring, use screened cable with screen earthed at detector end only
Product Features
- Reset Switch: Manual reset during registering and testing for system recovery
- Selectable Pulse Time: Sets pulse relay duration to 1S or 0.5 Seconds
- Pulse Relay Selection: Configurable to activate on vehicle detection or departure
- Sensitivity Reinforcement: Sets undetecting level to maximum sensitivity for large vehicles like trucks
- Adjustable Sensitivity: 4 sensitivity settings available
- Adjustable Frequency: 4 frequency settings to prevent signal interference with neighboring loops
- Filtering Option: Provides delay between detection and output relay switching to prevent false detection of small or fast-moving objects
- Permanent Presence Option: Maintains detection when vehicles stay within loop area for extended periods
