Overview Of The Temperature Controller Settings; Graco Factory P, I, And D Settings - Graco Therm-O-Flow Plus 243698 Instructions-Parts List Manual

Overview of the Temperature Controller Settings

The basic program settings for each temperature con-
troller satisfy most application needs. The defaults ar
for using a hose on zones 1 and 3, and a gun on
zones 2 and 4. These settings are preset at the facto-
ry, but can be changed. The input type, temperature
scale, and over temperature alarm point are the critical
controller settings that are set before doing an auto-
tune or using any controller in normal operation. See
Form 309100 for operation of the temperature controls.

Graco Factory P, I, and d Settings

Table 5 lists the P, I, and d settings for standard control
panels. These settings are preset at the factory. Use
the table for reference information only.

These P, I, and d values are usually generated by
running an autotune process for each heat zone. The
controllers will automatically find the proper P (propor-
tional), I (integral), and d (derivative) values during this
autotune process. These are values that allow the heat
zones to reach their maximum temperature as fast as
possible without significantly exceeding desired tem-
perature.
