The Serial Number box shows the serial number of the sensor currently connected.
Color Recognition Channels
The Color Recognition Channels section of the display window contains all color matching channel
parameters. The number of color recognition channels is dependent on the BFS 30M Color Sensor
model and the application program configures for the appropriate model. All of the selections in this
section are channel specific. For example, one channel can be programmed to output a high level when
a match occurs while another channel can be programmed to output a low level when a match occurs.
With the exception of the BFS 30M-USS-L04/L05-OD12, Color Recognition Channels can be
programmed to achieve multiple match outputs. For example, channel 1 can be programmed to 5%
tolerance, channel 2 to 10% tolerance and channel 3 to 15% tolerance using the same sample. This
allows the user to monitor variations in samples for further process analysis. The BFS 30M-USS-
L04/L05-OD12, provide four discrete signals in a binary format and as such, only one output may be
active at a time.
Channel
The channel drop box shows the number of channels available for color recognition. Select the
appropriate channel prior to changing the associated parameters. Note that the number of color
recognition channels is dependent on the BFS 30M Color Sensor model.
Recognition Mode
There are two color recognition modes; Color & Luminosity and Color only. The Color only mode
compares the proportion of each color component in the signal, checking to determine that the
proportions are within the allowable tolerance to detect a match. This allows for greater variation in
sensor-to-target distance than the Color & Luminosity mode. The Color & Luminosity mode evaluates
each color component, the luminosity level of each and compares them to the programmed values within
the allowable tolerance. The BFS 30M Color Sensor allows users to select color and color & luminosity
modes on an individual channel basis. Color and luminosity provides the highest precision while Color
only is better suited in applications where target flutter is present.
Recognition Enabled
The Recognition Enabled check box allows the user to enable or disable a particular channel without
altering the programmed color recognition settings. A single channel or multiple channels can be
temporarily disabled causing the sensor suspend checking of that channel for a color match. To disable
a channel, uncheck the Recognition Enabled box and select the Send All BFS 30M Color Sensor
channels button.
Color (%)
The RED, GREEN and BLUE Color (%) boxes show the values programmed into the selected channel.
If the channel was programmed in the Color & Luminosity mode, these values represent a percent of full
scale for each color component. If the channel was programmed in the Color only mode, these values
