Single channel traffic vehicle detection 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). |
