PART 3
OPERATION: Configuration Mode
3.1 Introduction
The instrument has two different modes of operation. The first, Run Mode, is
used to display values for the Process Variable, and to display or clear Peak
and Valley values. The other mode, Menu Configuration Mode, is used to
navigate through the menu options and configure the controller. Part 3 of this
manual will explain the Menu Configuration Mode. For your instrument to
operate properly, the user must first "program" or configure the menu options.
Turning your Controller On for the First Time
The device becomes active as soon as it is connected to a power source. It
has no On or Off switch. The device at first momentarily shows the software
version number, followed by reset

For first-time users: Refer to the QuickStart Manual for basic operation
and set-up instructions.
If you have the Serial Communications/Ethernet Option you can easily
configure the controller on your computer or on-line.
