Automatic Gate PD132 single channel Traffic Inductive Loop Sensor Vehicle Detector Signal Control as parking system Vehicle Loop Detector: 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. PARAMETERS: Supply voltage: 230VAC , 115V AC, 24V DC/AC, 12V DC/AC ( Seethe label on the detector) Voltage tolerance AC: +10% / -15% Voltage tolerance DC: 15% Power Consumption: 4.5VA Output relays: 240V/5A Operating temperature: -20C to +65C Storage temperature: -40C to +85C Frequency range: 20 kHz to 170 kHz Reaction time: 10ms Signal holding time: Unlimited / limited when loop is permanently covered 10 minutes Sensitivity: Adjustable in 4 increments Loop inductance: Total loop plus connection wiring: 50H to 1000H. Ideal is 100H to 300H Loop connection wiring: Maximum length 20 meters, twisted at least 20 times per meter Size of Housing: 78x40x108 mm (L x W x H) _x000D_
