manual includes two longer sections that will help
you to work with the control system:
•
Section 8 – “Using the Touch Screen and the
Gauges.”
This section will explain how to “Navigate”
through the Touch Screen : how to enter and
change values, and so on.
• Section 9 – “Setup and Configuration”
The first part of this section includes a more
complete explanation of the Lead/Lag system.
The rest of the section includes detailed setup
instructions.
If you are not familiar with the control system, the
installation and setup process will go much more
smoothly if you read through these three sections
before beginning work.
