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 informa-

tion for easy readability. The following sections 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 con-

figuration 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 (external to the UPS module) is open or the Control Power switch is OFF. If power is avail-

able and a display is blank, contact Liebert Global Services (1-800-LIEBERT). Note that status infor-

mation 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).
