3.0 OPERATION
3.1 Display Screen and Operator Controls
Each Liebert Series 600T UPS cabinet is equipped with a microprocessor-based Operator Control Panel and Dis-
play Screen and System Control Panel designed for convenient and reliable operation. The System Control Cab-
inet (SCC) performs different functions than the UPS modules. Each cabinet has the controls and displays
required to operate and monitor its functions. The locations of operator controls are shown in Figure 8 through
Figure 11.
The front location of the control panel enables the user to quickly identify the current status of the UPS system
and to perform most of the manual operations. The operator display screen is driven by an easy-to-follow menu-
prompted software program.
Features
The Series 600T interface display system enables the operator to easily perform the following:
• Obtain a quick indication of operational status:
• Is the critical bus OK?
• Is the UPS system OK?
• Which UPS modules are available?
• Is the battery available?
• Is the bypass line available?
• Monitor the power flow through the UPS system and monitor all meter readings:
• Is the critical load being supplied power from the UPS system or bypass?
• Are input, battery, and output voltage, frequency, and current readings at nominal levels?
• How much battery time is still available during an outage?
• Is the battery recharging after discharge?
• Execute operational procedures:
• Perform critical bus transfer/retransfer between the UPS system and the bypass line.
• Start-up and shut down the UPS system and each module.
• Shutdown the system and all modules instantly in the event of an emergency.
• Access status reports and history files:
• Obtain a complete listing of the present status of the UPS system and all modules (input, output, and
battery voltage, frequency, and current readings, and any alarms that may be present).
• Review a complete history report of all events leading up to and immediately after a fault condition.
• Examine an archive listing of all alarm conditions that have occurred over a period of time.
• Make adjustments to programmable parameters (access limited by Security Access function):
• Set the date and the time functions.
• Change the auto-dial phone number and the modem options.
• Select the number of auto-retransfer attempts.
