volt.

4.f. Test Sensors

The Test Sensors option is for testing sensors and system response. Press “4” from the menu and the display will

show:

Press ENTER to begin Testing Sensors.

If no loop boards are installed in the counter, the display shows:

The display is automatically set for eight axle sensors, and will indicate when a

respective sensor has been activated.

For example, if sensor two is activated, the display will temporarily show:

The display will show sensors as they are activated, and then return to the blank state.

If any loop boards are installed, the display will show:

If 1-2 Loop Boards

If 3-4 Loop Boards.

Axle sensors are displayed above, loop sensors are displayed below. Each □ is given for a loop; a square designates a

connected loop, a square with a top bar missing designates no loop connected. The presence of a vehicle in a loop is

designated by the square being replaced with a loop number.

Press the “9” key at any time to retune the loops after you connect or disconnect loops. ENTER or CLEAR takes you

out of the testing screen back into the main menu.

If you have a Piezo Board Version 4 Installed:

The Phoenix II is capable of accepting inputs from eight Piezo Electronic Sensors. The new version 4.0 Piezo Circuit

Board detects axles by measuring current flow from the Piezo Sensor. The old Piezo Circuit Board detected by voltage

level. The sensitivity adjustment is identical to the previous Piezo Circuit Board in that it is a percentage value, the value

of 5% being very insensitive and 95% being extremely sensitive. When you change the percentage value, the

electronics adjust the gain for you to accomplish the desired effect of raising or lowering sensitivity. You may also

individually set threshold, gain, and time yourself.

We do not recommend that you change these values unless you are having difficulty. To adjust electronic setting for a

particular piezo sensor using the counters keypad, hold the “ALT” key down and press the # key of the piezo channel.
