Parameters for PXR-4 Controllers
This instruction applies to the Fuji Electric PID
Controller with Fuzzy Logic, Model PXR-4 used
on the Neutec
™
J-2
r
casting machine.
NOTE: If you have a PXW-4 refer to page B-3 for
parameter settings
These instructions are used to improve the
heating speed to set-point, improve set-point
stability, and reduce overshoot in the event the
cast point (set-point) is missed. Additionally, the
machine operation has been programmed to
use the “cast on the way up” method applied on
the larger Neutec
™
J-series machines. The
programming uses the full capabilities of the
Fuji temperature controller including the Fuzzy
Logic feature, alert indicator light, and variable
balance adjustment.
