Tolerance Levels
After an object has been taught, move the object manually within
the sensing range or positions that can occur in your application.
Check that the programmed channel is effectively detecting the
color. If the color is not being detected reliably adjust the tolerance
one level higher. By repeating this procedure, the optimal tolerance
level can be determined.
Adjusting the tolerance levels on the 45CLR enables the user to
define the amount of variation in color that the sensor will detect.
For example, a tight tolerance will only detect the specific color
taught to the sensor while a wide tolerance can detect slightly
lighter or darker shades of the color. Up to five tolerance levels can
be selected as shown on the chart below.

1. Place the color target within the sensing range.
2. Enter teach mode by pressing SET for three seconds until the
green LED turns off and the yellow channel one LED turns on.
Note that the white light turns off when you enter teach mode.
3. Push SET for three seconds until the tolerance LED (red) turns
on. Press
X to adjust tolerance to the desired level. When
changing the tolerance levels, the green LED works as a guide
indicating if the color tolerance is too low for detection as
described in the Tolerance Levels section above.
4. Push for three seconds to confirm the desired tolerance level.
5. The sensor is now ready to operate (yellow channel one LED is
on when the target is present). White LED detection beam is also
on during normal operation.
1. Place the object with various colors within sensing range.
2. Enter teach mode by pressing SET for three seconds until the
green LED turns off and the channel one yellow LED turns on.
Note that the white LED light spot is also turns off.
3. Select the channel you want to teach using the
X button.
4. Press and hold SET until the green LED is blinking. Continue to
hold SET while moving the object to scan all colors by the
sensor’s white light spot. When you are finished scanning the
object, release the SET button.
Normal Teach
To teach the sensor to learn multiple colors using multiple channels:
1. Place the color target within the sensing range.
2. Enter teach mode by pressing SET for three seconds until the
green LED turns off and the yellow channel one LED turns on.
3. Select the desired channel to teach using the
X button. To
confirm the color to be taught for a selected channel Press SET
for three seconds until the red tolerance LED turns on.
4. Select desired tolerance level. When changing the tolerance
levels, the green LED works a guide indicating if the color
tolerance is too low for detection.
5. Press SET for three seconds until the red tolerance LED turns off
to exit teach mode.

Repeat instructions to teach additional channels.
Advanced Teach (Color Scan)
The Color Scan feature enables you to teach and detect objects
with various colors and individual multiple colors to each channel.
5. The sensor is now ready to operate. (Confirm that the scanned
objects turn the channel yellow LED on.)
Repeat instructions to teach additional output channels.
The Gating Input can be used to inhibit the operation and output of
the 45CLR. This allows the user to only operate the 45CLR when
another sensor detects that the object is present. For example, the
”gating” sensor detects when a bottle is present, and only at that
time the 45CLR detects the color of the cap.
45CLR ColorSight Setup
The 45CLR ColorSight is set up using the pushbuttons (SET and
X)
and the LED indicators on the top of the sensor. There are three
available ways to set up the sensor:
Simple Teach
To teach the 45CLR ColorSight to detect a single color using one
channel:
To teach multiple individual colors per channel
The Color Scan feature can be used to teach multiple individual
colors per channel using the same procedure as above. In step 4,
present individual colors in a sequential (without any disruptions)
manner.
