TROUBLESHOOTING

Release Sensitivity

h Set to Low if multiple detections or dropouts occur frequently at Normal.

h Set to High or Extra High to compensate for improperly positioned loops where run-ons occur.

h Set as low as practical. Check for run-ons or dropouts and set for best operation.

RESET PROCEDURE

If the detector is stuck indicating a vehicle present continuously or is otherwise unresponsive, follow the reset steps below:

With no vehicle present over the vehicle detector loop:

h Press and hold the Reset switch in the base station or timer for 1 second and then release. The ADVB display will go blank

for a few seconds and then should show “b” for a second or two.

h Reset is complete when the ADVB display shows a code other than “b” or “F”.

DETECTOR FUNCTION

To verify proper detector board function, disconnect one of the wires to the detector loop and verify that the board display changes

to “d”. Then reconnect the wire and the display should change back to one of the normal codes. If the display was originally

showing “d”, short the two loop terminals and watch for the display to change to “C”.
