thresholds from the least sensitive to the most sensitive. Setting the proper sensitivity level for the loop circuit provides

stability to the system. If set too high, the detector may detect adjacent traffic. If set too low, the detector may not detect

small vehicles or high bed vehicles.

The LCD includes an eight (8) segment bargraph that is a representation of the relative change of inductance as seen by

the detector. This automatically takes into account loop size, loop inductance, number of loops, number of turns, loop

geometry, lead-in length, etc. The bargraph is a sliding scale that is relative to the programmed Sensitivity Level. The

first (left-most) bargraph segment represents the minimum inductance change necessary for the detector to output a call at

the currently selected sensitivity level. Larger inductance changes will indicate more segments. Each additional segment

indicates that the next sensitivity level has also been met or exceeded. Therefore the bargraph indicates if the sensitivity

is set too high or too low, easily facilitating the ideal setting of the sensitivity level.

If the typical vehicle to be detected is not creating a five to six segment display on the bargraph, count how many

segments are being displayed and subtract six. If the number is positive, lower the sensitivity that many levels. If the

number is negative, raise the sensitivity that many levels. Example: The detector channel sensitivity is currently

programmed at three (3). The bargraph shows four (4) segments during a typical vehicle detection. Take four (4) (the

number of segments displayed) and subtract six (6) to get minus two (-2). Since the answer is negative, raise the

sensitivity level, currently at three (3), by two (2) to arrive at the desired sensitivity level of five (5).

The bargraph can also be used to take advantage of a direct relationship between the percent change of inductance caused

by a single standard automobile and a small motorcycle in the same loop / lead-in configuration. Adjusting the sensitivity

level for the channel until seven (7) segments of the bargraph are shaded when a standard automobile is present in the

loop zone ensures that the sensitivity has been set to detect a small motorcycle in the same loop zone. If the left most

segments of the bargraph are flickering when vehicles pass in the adjacent lane, the Phase Green Compensation can be

turned on to minimize the effects of adjacent lane detection (see Option 5). The second method of reducing adjacent lane

drops while the Max Presence timer is timing, the Max Presence timer is reset to the Max Presence time setting. The Max

Presence timer counts towards zero as long as the call output exists. If EOG (End of Green) control is OFF, the detector

channel resets at the time the Max Presence timer reaches zero. If EOG is ON, the detector channel goes into a wait state

when the Max Presence timer reaches zero. The channel remains in the wait state until either the call drops, or the green

input signal to the channel transitions from the ON condition to the OFF condition. If the call drops, no reset action

occurs. If the Max Presence timer is in the wait state when the green input signal transitions from the ON condition to the

OFF condition, the detector channel is reset with the vehicle over the loop. When the Max Presence timer is in the wait

state, the MAX PRESENCE - EOG message flashes on the LCD. NOTE: If the Max Presence timer does reset the
