Figure 3.294: Sensor Range Properly Set
A - High Voltage
B - Low Voltage
C - Sensor Operating Range
Sensor voltage must be between 0.5
–
4.5 V. If the voltage is too
close to either end of the voltage range, there will be difficulty
with calibration and operation of the AHHC. A properly set
sensor will have room on both ends of the voltage range.

Figure 3.295: Sensor Range too Close to the High
Voltage Limit
A - High Voltage

C - Sensor Operating Range
A sensor that is adjusted too close to the high voltage or low
voltage limit will have difficulty staying within the sensor
’
s
operating range of 0.5
–
4.5 V. If the sensor moves out of range,
the AHHC will stop functioning correctly.

C - Sensor Operating Range
A sensor with a voltage range that is too narrow will have
difficulty staying within the set range. The combine will
continually seek to keep the sensor within the set range.
