NOTE:
The following paragraphs provide brief
descriptions of the options contained in each
menu. Refer to Appendix A for detailed
descriptions of each menu option. Refer to
Appendix B for listings and descriptions of
displayed startup, status and error messages.
3.4. OPERATING MENU
The Operating Menu displays a number of key
operating parameters for the unit as listed in
Table 3-2. This menu is “Read-Only” and does
not allow personnel to change or adjust any of
the displayed items. Since this menu is “Read-
Only”, it can be viewed at any time without
entering a password. Press the
▲ arrow key to
display the menu items in the order listed (Top-
Down). Pressing the
▼ arrow key will display
the menu items in reverse order (Bottom-Up).
3.5. SETUP MENU
The Setup Menu (Table 3-3) permits the
operator to set the unit password which is re-
quired to change any of the menu options. To
prevent unauthorized use, a previously entered
password entry will time-out after 1 hour. There-
fore, the password must be reentered when
required. In addition to permitting password
entries, the Setup Menu is also used to enter
date and time, language to be used for display
messages, units of temperature measurements
and entries required for external communication
and control of the unit via the RS-232 port. A
view-only software version display is also pro-
vided to indicate the current Control Box
software version.
