represent the proportion of each color component in the composite signal (i.e. the sum of the color
components = 100%).
Tolerance (%)
The Tolerance spin boxes are used to set the tolerance for each color component individually. When the
colors of the samples are significantly different, for example, red, brown, yellow, then the tolerance
setting may be set to a higher value. When the colors of the samples are very similar, for example
similar intensities of the same hue (i.e. color), then tighter tolerance settings are necessary for reliable
differentiation.
Luminosity (%)
The Luminosity box shows the average of the red, green and blue color % for the selected channel when
in the Color & Luminosity Recognition Mode. When Color only is selected the Luminosity box is
blank.
Match Output
The Match output setting allows the operator to select either High or Low output on the associated
discrete output when a match occurs. By selecting High the output will pull to sensor V+ and by
selecting Low the output will pull to sensor ground. Whenever a channel is in a non-match condition the
output will pull to the opposite state.
Teach BFS 30M Color Sensor Channel
The Teach BFS 30M Color Sensor Channel button initiates a sequence of sampling the input signals
resulting in current values, tolerances and other specific channel parameters to be stored in the sensor.
Executing the teach function applies only to the selected channel. While the teach function is performed
by the sensor for several seconds all user selections in the application program are temporarily disabled.
Read All BFS 30M Color Sensor Channels
The Read All BFS 30M Color Sensor Channels button allows the application to load previously
programmed settings from a sensor into the application program for review, modification or saving to a
file. Reading the channels from the sensor into the application will overwrite any current settings and
parameters in the Color Recognition section of the display window.
Send All BFS 30M Color Sensor Channels
The Send All BFS 30M Color Sensor Channels button sends all the settings and parameters for all
channels to the sensor. This function is useful when recalling a saved file to re-programming the sensor.
Current Reading
The Current Reading section of the display shows current information received from the sensor. This
allows the user to place samples in the viewing area of the sensor and observe the levels of the red, green
and blue components. The Current Reading display is useful in initial set-up for determining optimum
sensor-to-target distance, sensor-target angle and relative reflected intensity of multiple samples prior to
beginning the teaching sequence.
