TEACHmodeselected.Jam Retroreflective TEACH is the default TEACH mode on CH1, and Jam Background Suppression TEACH is the
default TEACH mode on CH2.
See the Instruction Manual for detailed instructions and other available TEACH modes. The TEACH modes include:
Two-pointstaticbackgroundsuppression —Two-pointTEACHsetsasingleswitchpoint.The sensor sets the switch point
between two taught target distances, relative to the shifted origin location.
Dynamicbackgroundsuppression —Dynamic TEACH sets a single switch point during machine run conditions.The sensor
takes multiple samples and the switch point is set between the minimum and the maximum sampled distances.
One-pointwindow(foregroundsuppression) —One-point window sets a window (two switch points) centered around the
taught target distance.
One-pointbackgroundsuppression —One-point background suppression sets a single switch point in front of the taught
target distance. Objects beyond the taught switch point are ignored.
Dualintensity+distance —Dualmoderecordsthedistanceandamountoflightreceivedfromthereferencesurface.
See"Dual Mode Reference Surface Considerations" on page 12formoreinformationaboutselectingareferencesurface.The
output switches when an object passing between the sensor and the reference surface changes the perceived distance or amount of
returnedlight.
Jamretroreflective —JamretroreflectiveTEACHmodeisanextensionofDualModeoptimizedforjamdetectionwhena
background is present. This mode sets a window with two switch points centered around the taught target distance. Measurements
with valid intensity inside this window are qualified as not jammed. An independent jam range (RNG) value is set which defines the
minimum movement required, which in combination with an automatically determined intensity threshold, determines that an object
ismoving(notjammed).ALossofSignalfortheuser-definedtimeistreatedasajam.

detection when no background is present. This mode sets a background suppression point in front of the taught target distance.
Measurements with a valid intensity inside this window are qualified as not jammed. An independent jam range (RNG) value is set
by the user which defines the minimum movement required, which in combination with an automatically determined intensity

Manual Adjustments

NOTE: When FGS TEACH mode is selected, manual adjustment moves both sides of the symmetrical threshold
window simultaneously, expanding and collapsing the window size. Manual adjustment does not move the center point
ofthewindow.
NOTE: When Dual TEACH mode is selected, after the TEACH process is completed, use the manual adjustment to
adjust the sensitivity of the thresholds around the taught reference point. The taught reference point is a combination of
the measured distance and returned signal intensity from the reference target. Manual adjustment does not move the
