Ground Sensors Traffic Inductive Loop Vehicle Detector Signal Control

Description:

Noble vehicle loop detector is designed to accommodate numerours applications, can be adjusted intelligently to any environments and virtually liminating false detection.
Four selectable loop frequencies(20~80KHz) can completely eliminate any crosstalk.
Two-color LED status indicator for Detect,Power,and Loop Fault indication.
Two separate output relays

Features :

???
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.??????????????????????????????????????
Two separate output relays:
Presence Relay A is presence output. Can be extended for 0,2,5,8,10,15,20 or 30 seconds, programmable with external 10 way DIP switches.
Pulse Relay B, programmable with external 10 way DIP switches, provides presence, pulse on entry, pulse on exit, or failed output.

?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).?
