HPV_Kc
Tip Strip: HPV PID proportional gain
Units: %bar
Detail: Proportional gain. A value of zero disables proportional, integral, and derivative contributions to the
PID output. (See the equation in Auxiliary PID Controller Setup for reference.) Smaller values cause less
proportional contribution to the PID output. Larger values cause more proportional contribution to the PID
output. Negative values will generate PID outputs that are inversely proportional to the error ( Setpoint –
Process Variable ).
HPV_Kp_Action
Tip Strip: Proportional contribution of HPV PID controller
Detail: Indicates the contribution of the proportional term to the total PID output.
HPV_Ti
Tip Strip: Integral time constant for HPV PID controller (lower = stronger action. 0 = disabled.)
Units: min
Detail: Integral time constant. A value of zero disables integral contribution to the PID output. Smaller non-
zero values cause more contribution to the PID output. Larger values cause less contribution to the PID
output. Negative values should not be used.
HPV_Ti_Action
Tip Strip: Integral contribution of HPV PID controller
Detail: Indicates the contribution of the integral term to the total PID output.
HPV_Td
Tip Strip: Derivative time constant for HPV PID controller (higher = stronger action. 0 = disabled.)
Units: min
Detail: Derivative time constant. A value of zero disables derivative contribution to the PID output. Smaller
values cause less contribution to the PID output. Larger values cause more contribution to the PID output.
Negative values should not be used.
