Calibrating Reject-Confirm Times
This calibration menu has two sub-functions—the “Reject-1 Confirm Sensor” function
and the “Reject-1 Complete Sensor” function. Both are currently disabled, as shown by
the X across the eye icons in the screens below. In addition, each sub-function is used
only by a particular type of application.
• Reject-1 Confirm Sensor
The default values for “reject-1 confirm sensor” function looks like this.
• Reject-1 Complete Sensor
The default values for “reject-1 complete sensor” function looks like this.
What the Confirm Functions Do
In conveyor applications, the “reject-1 confirm sensor” function confirms that rejected
product has, indeed, gone into the reject bin. In gravity-feed and pipeline applications,
the “reject-1 confirm sensor” and the “reject-1 complete sensor” functions confirm that
the gate (which diverts contaminated product into the reject bin) has both opened and
closed.
Calibrating the Two (Confirm/Complete) Reject-1 Sensor Functions
The calibrate menu allows you to calibrate the reject-confirmation process by passing a
contaminated test product through the search head and having it rejected. For these
functions to work, you must 1) place a photo eye at the mouth of the reject bin (for
conveyor applications), or 2) have a gate-open and gate-closed sensor installed on the
reject gate (for gravity-feed, pipeline, and pharmaceutical applications). In addition, the
photo eye or gate-open and gate-closed sensor must be hard wired to the detector’s
input wiring board. The auto calibration, however, works whether you have one or two
reject-confirmation sensors active.
To calibrate the reject-confirmation process, do the following.

Make sure the calibration menu is highlighted.
