Control Menu
As with the Output Menu, the Control Menu will change, depending
upon the Output Type selected.
Note: These parameters are automati-
cally set during the autotune procedure. We do not recommend
altering the value of these control parameters unless your process
requires manual tuning.
Setting Derivative (Rate)

aspect of PID control.
If BOTH outputs are set
to direct-acting or
BOTH outputs are set
to reverse-acting, then
only one proportional
band selection will
be displayed.
