Dual Vehicle Traffic Inductive Loop Detector For Parking Access Control System

Description:

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.

Features :

1. Indicates and Switch:

Power Led: RED power LED indicates “Power ON”

CH1 Detecting Led:Continuously On: Indicates vehicle detection.
Blinking slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.
Blinking fast: Indicates loop is open circuit or too many twists after the loop.

CH2 Detecting Led:Continuously On: Indicates vehicle detection.
Blinking slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.
Blinking fast: Indicates loop is open circuit or too many twists after the loop.

2. Sensitivity Selection:

Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way dip switch setting.
User can select 8 different setting by changing the setting of the dip-switch to different modes as in the
dip-switch setting tables below. Dip switch 6, 7 and 8 for CH1 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive. Dip switch 3, 4 and 5 for CH2 sensitivity selection
with 0.8 being the least sensitive and 0.015 being the most sensitive.

 FAQ:

Q1: If the detector is not working?

A1: Press reset

Q2: If red led indicator is not fully lit?

A2: Check for power supply

Q3: If green led indicator blinks slowly?

A3: It maybe because the loop is short circuit or the no: of turns is not enough.

Q4: If green led indicator blinks slowly?

A4: It maybe because the loop is open or the no: of turns is too many.

Q5: If no: of turns is not enough?

A5: Lower the frequency (if the frequency is still too high, you must add more turns).

Q6: If no: of turns is too many?

A6: Higher the frequency (if the frequency is still too low, you must remove some turns).
