Responce time 10 - 90MS high quality Traffic Loop Detector can be used as barrier closing
Description:
The loop consists of several loops of wire and consideration
should be giving to the loop sensitivity when installing on different surfaces. Setting the correct sensitivity allows the loop to operate with maximum detection (16 levels via a trimpot). When detection occurs, the detector energises 2 relays for the output (each can be configured individually). This energising of the relay can be configured into different modes, by selecting the respective dip switch.
Sensitivity Selection
Sensitivity of the loop can be adjusted by the trimpot labeled “Sensitivity”. User can select 16 different setting by turning the trimpot with 0 being the least sensitive and “F” being the most sensitive.
Loop detectors in recent years have become a popular tool having innumerable applications in policing, right from surveillance operations to traffic control. Automation of gates and doors has become a popular usage of the loop detector.
The NBT-ILD™ vehicle loop detector is compatible with most gate operators. The ULT-MVP may be used in Center, Safety and Exit loop positions.Fifteen sensitivity settings allow for fine adjustment of the detection level.
Features
Compact Size: the compact and well engineered housing
Combines all of the industry requirements regarding
Features and functionality and allows this detector to be
Incorporated into any or existing traffic detection system.
Diagnostic Capabilities: Comprehensive diagnostics
Capabilities allow for accurate diagnosis of loop and
Installation problems.
Selectable Presence Time: The output of the presence
Relay can be selected to limit a detect output to a fixed
time(time>30 minutes)while a vehicle remains on the loop
Loop Frequency Indication: Interference between
adjacent loop/detectors can be determined by an integral
indication, and eliminated by changing the frequency
setting.

Troubleshooting
|
Symptoms |
Solution |
|
|
If the detector is not working |
Press reset |
|
|
If red led indicator is not fully lit |
Check for power supply |
|
|
|
Blinks slowly |
It maybe because the loop is short circuit or the no: of turns is not enough. |
|
Blinks faster |
It maybe because the loop is open or the no: of turns is too many. |
|
|
If no: of turns is not enough |
Lower the frequency (if the frequency is still too high, you must add more turns). |
|
|
If no: of turns is too many |
Higher the frequency (if the frequency is still too low, you must remove some turns). |
