Description
Proportional
band
PB 1
0…9999 0
Size of the proportional band
The gain of the controller decreases with
increasing proportional band.
With Pb 1,2 = 0 the controller structure is
ineffective (limit comparator response).
Continuous controllers: Pb1,2 must be >0.
Pb 2
0…9999 0
Derivative time
dt
0…9999 s 80 s
Influences the differential component of
the controller output signal.
The effect of the D component increases
with increasing derivative time.
Reset time
rt
0…9999 s 350 s
Influences the integral component of the
controller output signal.
The effect of the I component decreases
with increasing reset time.
Actuator
time
tt
5…3000 s 60 s
Actuator time range used by the control
valve for modulating controllers.
Cycle time
CY1
0.0…999.9s 20 s
With a switched output, the cycle time
should be chosen so that a) the pulsed
energy flow to the process does not cause
any impermissible PV fluctuations and b)
the switching elements are not overloaded.
CY2
0.0…999.9 s 20 s
Contact spacing
(dead ban
d)
db
0.0…999.9 0
The spacing between the two control
contacts for 3-state or modulating
controllers.
Switching
differential
HyS1
0.0…999.9 1
Hysteresis for switching controllers
with Pb1,2 = 0.
HyS2
0.0…999.9 1
Working point
Y0
-100…+100% 0%
Output for P and PD controllers
(when x = w then y = Y0).
Output limiting
Y1
0…100% 100%
Maximum output limiting.
Minimum output limiting.
(only effective with PB>0!)
Y2
-100…+100 % -100%
