Appendix A. Trouble Shooting

This Section is intended as a guide towards installation troubleshooting. It is in no way intended for the service or repair

of any type of the Phoenix II system.

Some basic problems can always occur during operation. Generally, they will be some small error in setup or sensor

installation. Listed below are some basic problems and possible solutions. If you cannot solve an installation problem,

or if you find a new solution to an old problem, please call Diamond Traffic Products. We are glad to help solve any type

of installation problem or receive new installation information.

Problem

Tubes are installed to collect Raw (Per-Vehicle) or Binned data, but errors keep occurring in the

data.

Solution

Are the tubes the same length? Are they stretched tight (both the same amount if using two tubes

per lane) across the roadway? Are there holes in the tubes (you can check this by plugging one

end of the tube and putting it underwater under slight air pressure (5 - 10psi max)? Is the end of

the tube which is not being connected plugged properly?

Problem

I’ve installed loops in the road, but I am not getting axle counts. Why?

Solution

The loops will not detect individual axles. They are Presence Sensors which will let the Phoenix II

know if a vehicle is present only. Road Tubes or Piezo Sensors must be used for axle counting.

If you are not equipped for road tubes, and you need axle counting capability, contact Diamond

Traffic Products.

Problem

I’ve installed tubes to collect Raw (Per-Vehicle) data, but I keep getting errors. I check the “Test

Sensor” option, and the tubes are functioning.

Solution

Are the tubes in the correct order? Remember – the tubes must be connected in sequence

depending on your lane assignment and configuration. Check the Tables in Section 2.a for

confirmation. You may have a lane installed backwards. Another possible problem is bi-

directional traffic. Do you have the directional option enabled?

Problem

I have installed a Phoenix II in a busy roadway. The counter has stopped collecting data when I

arrived. Everything seems to be working.

Solution

Check the show status option. Is the memory full? You may need to retrieve the data from the

counter more often.
