Parameter setting

Here, control variables (parameters) can be set for the device features.
This includes: Date and time, controller parameters and controller setpoints.
10.5.1

Date and time

The following table explains the parameters for setting the date and time.

In Ecolab PC setup date and time in the on-line parameters are set. See
operating instructions 417102269, chapter 'Date and time' .
10.5.2 Parameter sets (controller parameters)
The parameters for the controller channels determine the control characteristics of the
respective control loop. These parameters must be adapted to the prevailing conditions of
the process for stable control behaviour. In this way, each controller channel can be
adapted to changing process conditions in order to keep the control behaviour stable.
The best parameter settings can usually be found by self-tuning the controllers. However,
this only works for linear processes.
For the operation of the controllers see operating instructions 417102269, chapter
'Operation of the controllers' .
For non-linear processes (control systems), it is recommended to set the parameters
manually.
The following table provides an overview of the parameter sets of the controller channels.
Depending on the configuration of each controller channel, only the valid parameters for
the command are active. Those that are unused appear light gray, but cannot be edited.
Two duplicate parameters are related to the first and second controller output.
