Features of loop detector :
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) Switch Selectable Sensibility: 11 levers adjustable sensitivity setting are available on the switches to allow flexibility in configuration.
4) Pulse Relay Selection : The Pulse Relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loop ;
5) Permanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods .
6) Sensitivity Boost : This feature sets the undetect level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles ;
7) Switch Selectable Frequency : 4 frequency settings are available to prevent cross-talk between adjacent loops ;
8) 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 ;
Competitive Advantage:
Self-turning range: 20-2000μH
Response Times: Turn-on 10-90MS
Turn-off 10-90MS
Sensitivity: 16 way selectable
Highest 0.010% DL/L
Lowest 2.56% DL/L
Loop Installation:
The loops are sealed using a “quick-set” black epoxy compound or hot bitumen mastic to blend with the
roadway surface.

Applications:
Troubleshooting:
| Symptoms | Solution |
|
| If the detector is not working? |
Press reset |
|
| If red led indicator is not fully lit? | Check for power supply | |
If green led indicator ? |
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). | |
