Inductive Loop Detector Access Control , Metal Video Signal Detector
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 :
1) Reset Switch : The reset switch enables the detector to be manually reset during commissioning and testing . This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection ;
2) Selectable Pulse Time : This feature sets the length of time that the pulse relay will be energized for 1 Second or 0.5 Seconds ;
3) Pulse Relay Selection : The Pulse Relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loop ;
4) Sensitivity Boost : This feature sets the undetect level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles ;
5) Switch Selectable Sensibility : 11 levers adjustable sensitivity setting are available on the switches to allow flexibility in configuration ;
6) Switch Selectable Frequency : 4 frequency settings are available to prevent cross-talk between adjacent loops ;
7) Filter Option : This option is used to provide a delay between detection of the vehicle and switchiing of the output relay . This relay is normally used to prevent false detection of small or fast moving objects ;
8) Permanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods .

Applications:
Traffic Control Application
Vehicle Counting
Toll Systems
Traffic Analysis
Parking Control Application
1. Install the detector in a weatherproof housing.
2. The detector should be as close to the sensing loop as possible.
3. The detector should always be installed away from strong magnetic fields.
4. Avoid running high voltage wires near the loop detectors.
5. Do not install the detector on vibrating objects.
6. When the control box is installed within 10 metres of the loop, normal wires can be used to connect the control box to the loop. More than 10 metres requires the use of a 2 core shielded cable. Do not exceed 30 metres distance between control box and loop.

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).
