Pro-EC44 2-Loop Graphical Profile Controller & Recorder
Pro-EC44 Product Manual - 59540-2 September 2014 Page 33
7 Application Setup
Before beginning configuration, consider how the controller will be used in your application.
For instance, how many control loops are needed, is cascade or ratio control required, will
the unit control a valve motor, do you need setpoint profiling etc. Consideration should also
be given to the output types, alarms and tuning method.
This section is intended to help with this process, guiding you through the major configuration
settings. Additional information can be found in the relevant sections of this manual, including
the glossary, configuration menus, and dedicated sections for major features. These are
listed in the table of contents.
Pre-commissioning Considerations
An easy Setup Wizard is available for basic applications ( see page 43 ) where the most
commonly required parameters are present for adjustment in turn. The wizard has a sub-set
of the full configuration menu options. For more complex applications where the wizard is not
sufficient, consideration must be given to the following fundamental questions:
If fitted, how will the 2nd input be used?

One loop only (if the 2nd input not fitted or not used in this application)

Two independent control loops (see page 50).

Valve feedback for loop 1 (see page 85 Error! Bookmark not defined. ).

A “redundant” backup for the 1st input (see page 83).

Cascaded with the first control loop (see page 78).

A reference input for ratio control (see page 81).
How will the instrument physically control the process?

Primary only or primary & secondary control outputs ( see page 210) .

Direct valve motor drive outputs ( see page 84) .
The table below shows the main input and control configuration settings for these application
types (
see page 45 for the configuration menus ).
