Liebert Series 600T - Manual (Page 34)

28 Operation
Figure 12 Menu Tree
Figure 12 illustrates the primary screens that you can access through the Operator Interface Display System. The
liquid crystal display (LCD) screen provides a full 80 characters by 25 lines of information for easy readability.
The following subsections describe what these screens display and how and when to use them.
Module status information is available on the display screen, provided Control Power is ON, even when the
UPS module is not operating. System status information is available on the SCC display screen and at local and
remote terminals when at least one module is on-line or when the bypass source is available.
The screen will automatically display the Monitor/Mimic during normal operation. The System configuration
screen will be displayed during start-up and whenever a system reset is required.
If a module display screen is blank, either power is not available, the Rectifier Input (RIB) circuit breaker (exter-
nal to the UPS module) is open, or the Control Power switch is OFF. If power is available and a display is blank,
contact Liebert Global Services. Note that status information may be available at local and remote terminals. Use
control touch pads at the SCC to manually transfer the critical load to the bypass line if the SCC display goes
blank while load is on UPS (a very unlikely event).
