Banner Q4X Series - Slope; Zero Reference Location; Shift the Zero Reference Location after a TEACH

Note: The Q4X uses a dynamic measurement rate, so these response times are worst-case.
3.1.4 Slope
Use this menu to set the slope as positive or negative. This swaps the 0 V and 10 V (4 and 20 mA) values. The default is
positive. The slope is defined relative to the zero reference, so if the zero setting is changed from near to far, a slope will be
considered positive if the analog output increases as the target becomes closer to the face of the sensor.
• —the slope is positive
•
—the slope is negative

3.1.5 Zero Reference Location
Use this menu to select the zero reference location. Changing the zero reference location only affects the readout on the
display and does not affect the output. The default is , 0 = the front of the sensor.
•
—0 = the front of the sensor; the measurement increases further from the sensor
• —0 = maximum range; the measurement increases closer to the sensor
3.1.6 Shift the Zero Reference Location after a TEACH
Use this menu to select whether the sensor shifts the zero reference location based on the last TEACH process. The default
is , 0 = the front of the sensor or the maximum range.
• —Shift the zero reference location to one of the taught positions with each TEACH
•
—0 = the front of the sensor or the maximum range, depending on the setting
This figure illustrates three examples of how changes to the zero and shift settings affect what distance readout is shown on
the display when in 2-pt TEACH mode. Changes to the zero setting affect the direction in which the distance increases.
Turning the shift setting on sets the taught location as the reference point for any distance measurement. For two-point
TEACH, this is the 0 V (4 mA) point. For one-point TEACH, this is the 5 V (12 mA) point.
