Spacing
Violations
When Profile mode is selected, select this check box to use focusing data and not
photoeye, to identify whether there is a spacing violation.
Fixed Focus
Value
When Fixed mode is selected, enter the fixed focus value in the field provided.
This parameter indicates the fixed focus position used when the position sensor related
to the camera is not used. The possible values are from 0 to 32767 mm where 0 is the
farthest valid station reading distance from the camera. The default setting is 0.
0 (zero) is referenced from the camera sensor.
This distance must be greater than the Far Working Distance (Z) set in the Device
settings>camera>mounting>automatic calibration parameters.

Tracking
Offset
When Profile mode is selected, enter the tracking offset in the field provided.
The Height sensor can be positioned either above or below the 0 focus height as shown
in the figures. However it should not be positioned above the level of the tray/box. In this
case the tray/box would never be detected so the Tracking Offset must be set to
compensate. This Offset then is added to the Percentage of Tray Depth to Set AF
therefore degrading the focus precision.
