AUTO CUTTER
Auto Cutter Setup
Introduction
The Auto Cutter option is for cutting the sample during either Method A or Method A/B tests. The cutter is engaged
at the end of each, defined cut time within the test. For example, if a Method A test is defined to have 3 sample cuts,
at 60 second intervals, then the auto cutter will cut the extrudate at the end of each 60 second interval. Also, the
auto cutter will cut the extrudate at the end of the defined Melt Time, before the test sample time is to begin.
The Auto Cutter option is triggered from the LMI main PCB via an 8-pin connection to the PCB. The Auto Cutter
option cuts in a single, 360-degree rotation and drops the cut sample down below the barrel in the work surface
above and to the rear of the display. The cutting action is accomplished by using a sharpened, thin, flexible blade
against a rigid, Teflon cutting surface. The cutting surfaces are rotated via a stepper motor. Homing and
Positioning are controlled within the motor’s own, on
-board electronics and a position sensor tied
to the motor control.
