Menu Screens - McQuay AGZXXXBS Series Installation, Operation And Maintenance Manual

For example, selecting ALARM will go the next row of menus under ALARM
(ALARM LOG or ACTIVE ALARM). Selecting VIEW will go the next level of
screens under VIEW (VIEW UNIT STATUS or VIEW UNIT TEMP). Selecting SET
will go to a series of screens for viewing and changing setpoints.
MENU Key
The MENU key is used to switch between the shortcut method (known as the MENU
mode and as shown in Figure 26) and scrolling method (known as the SCROLL mode
shown in Figure 27). The MENU mode is the shortcut to specific groups of menus
used for checking ALARMS, for VIEWING information, or to SET setpoint values.
The SCROLL mode allows the user to move about the matrix (from one menu to
another, one at a time) by using the four ARROW keys. A typical menu screen is
shown in Figure 27.
Pressing the MENU key from any menu screen will automatically return you to the
MENU mode as shown in Figure 26.

Menu Screens

The menus are shown in the controller display. Each menu screen shows specific

cases they are used for checking and clearing alarms, and in some cases they are used
to set setpoint values.
The ARROW keys on the controller can be used to navigate through the menus. The
keys are also used to change numerical setpoint values contained in certain menus.
Changing Setpoints
Pressing the ENTER key changes the function of the ARROW keys to the editing

These four edit functions are indicated by one-character abbreviation on the right side
