KPG*
0.10 to 10.00 PROCESS GAIN LOOP 1—This is the Gain of the
process being tuned on Loop 1. It is automatically
calculated during tuning process. This is normally a READ
only value. It should only need to be changed if the
controller fails to identify the process. In this case, set the
value to the algebraic value of PV in percent, divided by
output in percent while in the manual mode.
ATTENTION
Note you must disable Accutune to change
tuning constant values from the keyboard.
SP CHAN2*
5 to 15 % SETPOINT CHANGE LOOP 2—The minimum setpoint
change on Loop 2 that will result in re-tuning must be
configured between 5 % and 15 %.
KPG 2*
0.10 to 10.00 PROCESS GAIN LOOP 2—This is the Gain of the

controller fails to identify the process. In this case, set the
value to the algebraic value of PV in percent, divided by
output in percent while in the manual mode.

CRITERIA*

TUNING CRITERIA (SETPOINT ADAPTIVE)—Select a
criteria best suited for your process on Loop 1.
NORMAL—Original critical damping (no overshoot).
FAST—A more aggressive tuning with a minimal possible
overshoot of less than 0.5 %.
