Troubleshooting
Symptom
Possible Cause
Solution
Green LED not on No power
Check the power supplied to the MVP D-TEK on
pins 1 (white wire) and 2 (black wire). Voltage should
read between 12-240 VDC/AC.
Green LED
fast flash
Loop wire shorted or not
connected
Check the loop resistance with a multimeter to confirm
a reading between 0.5 ohms and 5 ohms. If reading is
outside of this range, replace the loop. The reading
should be steady.
Check loop connections to terminals
Momentarily flip the RESET switch down
Green LED
slow flash
Loop wire was previously
shorted or open
Check the loop resistance with a multimeter to confirm
a reading between 0.5 ohms and 5 ohms. If reading is
outside of this range, replace the loop. The reading
should be steady.
Momentarily flip the RESET switch down
Red LED on
constantly (stuck
in detection
mode)
Faulty loop
Poorly crimped
connection or loose
connection
Perform a megger test from loop lead to ground,
it should be more than 100 megaohms.
Check loop connections to terminals. Verify splices are
properly soldered and sealed against moisture.
Detector detects
intermittently
when no vehicle
is on the loop
Faulty loop
Poorly crimped
connection or loose
connection
Cross-talk between
multiple loop detectors
Loop not securely
installed to prevent
movement of loop in
pavement.
Perform a megger test from loop lead to ground,
it should be more than 100 megaohms.
Check loop connections to terminals. Verify splices are
properly soldered and sealed against moisture.
Set multiple loops to different frequencies
Verify that loop is securely installed in pavement and
that site is in good condition preventing movement of
loop wires.
