The 80-character liquid crystal display (LCD) allows visibility under varied lighting
conditions. When the keypad and display are not being used, system information is
displayed after a user-defined period of inactivity. Pressing the Menu key during the
display of default message returns the display to the last message shown before the
default message appeared. Any trip, alarm, or pickup is displayed immediately,
automatically overriding the default message.
The 339 display messages are organized into a Main Menu, pages, and sub-pages. There
are four main menus labeled Actual Values, Quick Setup, Setpoints, and Maintenance.
Pressing the MENU key followed by the MESSAGE key scrolls through the five Main Menu
headers, which appear in sequence as follows:
