Product Description

DC 24V Electronic Single channel vehicle loop detector for parking & traffic

 

About loop detectors

 

Loop detectors are used wherever vehicles have to be detected, for example: monitoring and safe guarding access ways or counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems in car parks or activating card dispensers in car parks.

Install 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 (mustn’t fix cling to the cabinet). A correct loop configuration and detector installation will ensure a successful inductive loop detection system. Loop of several important parameters include: loop figure, size, and turns, install methods (details as “Loop installation guide”).

 

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.

 

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.

 

Filter

To eliminate interference of bad environment, the filter mode is activated by setting the DIP6 Switch to “ON” site. In filter mode, the reaction time of the detector is delayed, and the sensitivity is reduced. Usually, the filter mode is disabled by setting the DIP6 Switch to “OFF” site.

 

[Attention]

If the detector isn’t working normally, you must check the loop and wiring at first, and then alter the frequency or the sensitivity. At last ,try to set it to filter mode.

 

Output Relay

The relay2 is pulse output. If DIP7 is “OFF” site, when a vehicle is detected passing over the inductive loop, the relay is energized( Pin3 and Pin4 is shorted) and de-energized ( Pin3 and Pin4 is opened) after 500ms. If DIP7 is “ON” site, when a vehicle is detected departing the loop, the relay is energized ( Pin3 and Pin4 is shorted) and de-energized ( Pin3 and Pin4 is opened) after 500ms.

The relay1 is presence output. When a vehicle is detected passing over the inductive loop, the relay is energized( Pin5 and Pin6 are shorted) until the vehicle is detected departing the loop.

 

Presence Time

The presence time may be set to permanent presence or to limited presence. In permanent presence mode the detector will continuously compensate for all environmental changes whilst there is a vehicle present over the loop, the presence mode is set with DIP8 Switch and is configured as follows: OFF:Limited Presence ( 5 minutes), ON:Permanent Presence.

 

Reset Switch

The detector automatically tunes to the inductive loop connected to it when the power is applied, whether on initial installation or after any break in power supply. Should it be necessary to retune the detector, as may be required after changing any of the switches or after moving the detector from one installation to another, momentary operation of the RESET switch will initiate the automatic tuning cycle.
