Car Park Sliding Swing Barrier Sensors Gate Opener Single Double Channel Vehicle Access Inductive Vehicle Loop Detector

Product Description

Car Park Sliding Barrier Sensors Gate Opener Single Double Channel Vehicle Access Inductive Vehicle Loop Detector

This loop detector used for wherever vehicles have to be detected,Monitoring and safe-guarding access ways or for counting vehicles. Output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems or activating card dispensers in parking lots. Uses advanced microprocessor technology and can work in diverse environments. Has two way output relays: one is unlimited output when loop is permanently covered and while the other is multiple mode that can be set by users.

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.

Frequency

To eliminate interference of two neighbouring wire loops or loop detectors, the frequency can be altered.

Sensitivity

The sensitivity of the detector allows the detector to be selective as to the change of inductance necessary to produce an

output. There are four sensitivity selections and are set as follows by DIP3 and DIP4 Switch.

Automatic Sensitivity Boost

Automatic sensitivity boost is selected by DIP5 switch on the front of the enclosure and is set as follows: OFF - Disabled, ON –Enabled. Automatic sensitivity boost causes the sensitivity to be boosted to a maximum on detection on the vehicle, and maintained at this level during the presence of the vehicle over the loop. When the vehicle departs the loop and detection is lost the sensitivity reverts to the pre-selected level.
