PID Controller FCM
BASE RESET Field
This field specifies the base value for the reset. If no adaptive functions are turned
on, the base reset is the active reset of the FCM. When an adaptive function is turned
on, all changes in active reset due to the algorithm for that function are based on the
base reset. Valid entry is a decimal number.
PREACT TIME Field
This field specifies the Pre-act time value. Valid entry is a value set between 0 and
32 minutes.
INTEGRAL TYPE Field
This field specifies the type of integral (reset) control action. Valid entries are:
LIMITED OUTPUT MODES Field
This field specifies whether the output limits are applied to the manual output, track
output, and/or auto output signals. Valid entries are: NONE, MAN, AUTO,
AUTO/MAN, TRK, MAN/TRK, AUTO/TRK, ALL
CONTROLLER ACTION Field
This field specifies whether the FCM output is direct or reverse acting. Valid entries
are:
232
NONE reset response is turned off.
STD reset response is turned on and is operating with the standard
algorithm. It is used with either adaptive gain or adaptive reset
and/or external feedback. Manual reset must be turned off.
MICROSCAN - reset response is turned on and is operating with the
Microscan algorithm. It is used with either adaptive gain or adaptive reset, but
not with external feedback. Manual reset must be turned off.
DIRECT - output of FCM increases as input to FCM increases
REVERSE - output of FCM decreases as input to FCM increases
