For access to this level press
To switch to the next/previous configuration point (depending on the scrolling direction mode) press
Inside the configuration level it is not possible to switch over to the manual mode.

Optimisation
Selection:
Optimisation is triggered by:
•
•
When tunE is shown cyclically in the setpoint display SP then the optimisation process is running.
optimisation from manual mode
•
Set target setpoint SP
•
Switch to manual mode
•
By opening/closing the actuator the actual value PV
is set on a higher/lower value than the
target setpoint (a)
•
Wait until PV is in a stable state (b)
•
Switch over to configuration level
•
Set "OPt = 1"
•
To optimise a PI-controller set derivation action time
"td = 0"; to optimise a PID-controller set "td ≠0"
•
If known, set process gain "P.G"
(usual setting: P.G = 100%)
•
Back to operating mode
•
Switch over to automatic mode. Thereby optimisation is

for automatic determination of favourable control parameters.
0 No optimisation
1 optimisation activated
manual mode:
switch over to automatic mode by pressing
automatic mode: changing the setpoint SP (not for external setpoint)
Procedure of optimisation:
Koepffstraße 5

optimisation from automatic mode
•
Set initial setpoint SP
•
Wait until PV is in a stable state (b)
•
Switch over to configuration level
•
Set "OPt = 1"
•
To optimise a PI-controller set derivation action time
"td = 0"; to optimise a PID-controller set "td ≠0"
•
If known, set process gain "P.G"
(usual setting: P.G = 100%)
•
Back to operating mode
•
Set target setpoint SP. Thereby optimisation
is started, "tunE" and the manipulated variable appear
alternate, actuator changes
•
During the optimisation process no inputs or
switch over are tolerated
