Manual optimizing

The parameters

Pb I

Pb II

and

are defined by manual optimizing to obtain optimum control

dynamics. A trial run and an oscillation test is made for this purpose.

Getting started

– For the use of the controller, a

complete configuration

(page 20) and

parameter setting

(page 28) must first be made.

– The control elements should be deactivated by

Off / manual mode

(page 18).

– Connect a

recorder

to the sensor and set it in line with the dynamics of the controlled system and the set point.

The actual value difference must be recorded for the differential controller.

– For a three-state and/or split range controller it is required to record the On and Off time of the switching output I and/or the continuous output

(e.g. with another recorder channel or with a timer).

– Configure the

limit monitors

(controller type Code = 0).

– Set the output cycle time to minimum:

0.5

– If possible, switch the limiter of the regulation ratio off:

Y H

100

– Lower (and/or raise) the

set point

so that the overshoots and undershoots will not take impermissible values.

Performance of a trial run

– Set

dbnd

MBU

for three-state and/or split range controller (switching output II must not respond).

Set

dbnd

for step controller (switching output II must respond).

– Start the recorder.
– Activate the control elements in

automatic mode

– Record two overshoots and two undershoots.

Trial run ended for two-state, continuous and step controller.

With three-state and/or split range controller proceed as follows

– Set

dbnd

to cause more oscillations with switching output II active, wait for two overshoots and undershoots.

– Record the

On time

and the

Off time

of the last shoot of the switching output I and/or the continuous output.
