Parameter Description
RESET (Integral Time) -
adjusts the controller's output
according to both the size of
the deviation (SP-PV) and the
time it lasts. The amount of
corrective action depends on
the value of Gain.
The reset adjustment is
measured as how many times
proportional action is repeated
per minute (Repeats/minute)
or how many minutes before
one repeat of the proportional
action occurs
(Minutes/repeat).
RATE action, in minutes
affects the controller's output
whenever the deviation is
changing; and affects it more
when the deviation is changing
faster.
Applies Gain to the
Feedforward value (FFV).
Feedforward Input is multiplied
by this value.
MANUAL RESET- is only
applicable if you do not use
RESET (Integral Time).
