Operation
2.0OPERATION
The Liebert NXL UPS is equipped with a microprocessor-based display touchscreen designed for con- venient and reliable operation. The display is driven by an easy-to- follow, menu-prompted software.
2.1Features
The Liebert NXL interface display enables the operator to perform such tasks as:
•Quickly check operational status
•Monitor the power flow through the UPS system and all meter readings
•Execute operational procedures
•Check status reports and history files
•Adjustment programmable parameters (access limited by security access function)
•Adjustment output voltage before performing a manual load transfer.
The touchscreen is a white-background display with multicolor text. The display turns on automati- cally, but after 15 minutes of inactivity the backlight will go out and the display will appear very dim. Touching the screen will reactivate the backlight; the backlight will again be active for 15 minutes. If any screen other than the mimic screen is accessed, that screen will be displayed for 5 minutes with- out any interaction. If there is no activity for 5 minutes, the display will revert to the basic mimic screen.
