4.1.1Control Interface—Three Main Menus

The Liebert iCOM control has three main menus: User, Service and Advanced.

The User menu contains the most frequently used features, settings and status information. The Ser- vice menu contains settings and features used to set up unit communications and for unit mainte- nance. The Advanced menu contains settings used to set up the unit at the factory.

NOTE

The Liebert iCOM’s Advanced menu is for factory use only or in consultation with the factory service department.

NOTE

Menu settings may be viewed without a password, but changing settings requires a password. If a password is required, the Liebert iCOM shows a prompt to enter the password. The password for the User menu is 1490. The password for Service menu is 5010. For details on entering a password, see 4.1.3 - Entering the Password

When the buttons on the Liebert iCOM control have not been pressed for a short period, the display backlight turns Off. Pressing any key will turn the backlight On (wake up the screen) and display the Status menu of the last cooling unit viewed. The Status menu will show the cooling unit’s operational mode(s), return air temperature and humidity readings, temperature and humidity setpoints and any active alarm conditions.

If the cooling unit has a large display and is not on a network, or if the unit has a small display, whether it is networked or stand-alone, the Status menu will display only that cooling unit’s informa- tion. Any large display that is connected to a network can be used to view any cooling unit on the net- work or show an average view of the entire system of cooling units.
