Application
The controller is designed to solve simple, basic control tasks,
especially in the field of temperature control.
Description
The control task can be done with P, PI, PD, PID or a simple
On/Off action. The right controller parameters are traced with an
automatic self-tune function. In the ensuing operation, a Fuzzy
Logic feature is used to effect an indirect adaption of the con-
troller parameters, which have the effect of optimising and stabi-
lising the control action even outside the stationary condition (e.g.
during big setpoint jumps).
The alarm function is selectable. Apart from the minimum or ma-
ximum value monitoring of the process variable or of the control
deviation, it can also be used as a time relay. Additonally, a fur-
ther function such as ramp rate can be adjusted for the setpoint.
All settings can be stored in a non-volatile memory and thus
remain unaffected by any power supply interruptions.
