Description
Controller structure 2 for the output of a double-
setpoint controller.
Modulating controllers can only use PI or PID.
Xp1, Xp2
The controller structure is ineffective if Xp1, 2 = 0 !
(thermostat function)
Xp1, 2 must be > 0 for proportional controllers.
Tv1, Tv2
Tn1, Tn2
Cy1, Cy2
With a switching output, the switching cycle should
be chosen so that the pulsewise energy feed does
not cause impermissible fluctuations in the process
values, while at the same time not overloading the
switching devices through excessive switching.
Xsh
Spacing between the two control contacts in
double-setpoint or modulating controllers, or pro-
portional controllers with integral actuator driver.
Xd1, Xd2
Hysteresis in switching controllers with Xp = 0
TT
The time range used for the regulator valve in
double-setpoint controllers or proportional
controllers with an integrated actuator driver.
Y0
Output level for P and PD controllers
(for x = w , y = Y0)
Y1, Y2
Output level limiting restricts the controller output
signal to values between the maximum (Y
minimum (Y
) limits.
