represented by the icon.
Before we travel using some of the icons, let’s look at the navigation possible from the
rest of the screen.
To move off of the bottom icon menu, press the UP ARROW. One of the compres-
sors is now selected. In this particular screen, the information above the compressor
icons pertains to the whole rack, and the information below the icons applies to the
compressor that is highlighted. If you press the right arrow key you will move the
cursor to the next compressor; as before, the information at the bottom of the screen
will pertain to the highlighted compressor. If you press ENTER with a particular
compressor highlighted, you will get a screen with run times and other available
information about the compressor. EXIT will return you to the previous screen.
Getting back to
The Icon Menu When you are working with a screen that has an icon menu at the bottom, and you
have left the menu to enter the main body of the screen, you can return to the icon
menu by pressing the MENU key. When using a PC, you can back up one screen by
clicking in the screen title area.
Viewing and
Changing Settings Back at the Suction Status screen, select the “Settings” icon (the fourth one from the
left), and we’ll see how settings are changed.
Here is the Suction Settings screen:
Notice that on the icon menu, the suction icon is no longer in reverse video, but the
settings icon is. As we did to see the compressor screen, we leave the menu by
pressing the UP ARROW, which moves the cursor to the topmost changeable field on
the screen, the Setpoint field. Now, if you are authorized at the “Refrigeration
Settings” or “Refrigeration – All” level or above, you can change the values of the
settings.
Changing
Numeric Values To change a numeric value, press the EDIT +/- key to toggle to edit mode, then
simply key in the new value from the keypad. At your PC, right click on the field, and
type from the keyboard. Remember that if a field has a decimal point, you must
enter a digit (even a zero) for each place to the right of the decimal point. When
