Set Points
About Set Points
The set point value is the target weight or level. It may be set in either
net, gross, ROC*, Total*, or Peak* hold weight units. When entering
this value, the corresponding LED flag will appear on the display. The
operator may toggle this flag to the desired mode by pressing the
MODE button. Refer to the Set point Limits section following installa-
tion for a description of set point limits.
NOTE:
Only works when the ROC, Total, or Peak options are installed in the controller.
Set Point Limits
Dead Band Limits
The dead band value can be set as a positive or negative value. It is
used to prevent relay chatter once the set point is reached.
