5 Operator Control and Display Panel
5.1 Introduction
The Vertiv™ Liebert® EXM2 Touchscreen Control Panel’s integrated interface simplifies monitoring and managing single or
multiple Liebert UPS modules. The control collects a profusion of information about the health of the modules and presents it
in a standardized format. This simple, dynamic display speeds operator response to changing power input and demand. Many
of the settings will depend on the UPS type and features. Many other settings will be made during the UPS setup by Vertiv
Tech service personnel. The Vertiv Liebert EXM2 Touchscreen Control Panel’s interface will display data either graphically or
in text. The Status Scroll Bar at the top of the touchscreen display summarizes system conditions. The bar changes color to
indicate status and includes an icon matched to the status. The Status Gauge displays such details as power demand from
the connected load, input power quality, output and bypass on each phase and battery capacity. The Vertiv Liebert EXM2
Touchscreen Control Panel’s mimic display shows the comprehensive system information that the operator needs: Is input
power connected? Are there any alarms? Which breakers are open and which are closed? Is the UPS on battery? How much
run time is available? Checking a particular component is as simple as touching it on the mimic display—Detailed data
appears, allowing the operator to respond. Visual and audible alarms alert personnel to faults and alarms requiring immediate
attention. Passcodes for each level of access—Operator, Administrator and Service—secure the UPS against unauthorized
changes. Personnel without a passcode can view UPS status, but cannot change any functions or the appearance of the
interface.
