Operation and Maintenance Manual,
Automatic Transfer Switch Controller, ATC-900
3.4 Display and Menus
The ATC-900 provides a comprehensive array of monitored param-
eters, setpoints, and messages via its easy to read Color Display
Window.
3.4.1 Color Display
The color display, under Main Menu contains six main top level
functions. See Figure 7a. Remember, the display is not a touch
screen; one must use the push buttons below the screen. This
particular screen is showing 120 volts single phase and both of
the sources are available.
From these top level menus, one can navigate through the fea-
tures. Section 5 shows how to program setpoints and I/Os. Sec-
tion 7 shows how to view and download Historical Data and
Events, setpoints, and firmware by using a thumb drive (memory
stick). See Appendix A for Status Display Messages. Below is a
map of the Display Menus.
