1.0 INTRODUCTION
The 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 settings will be made by
Vertiv personnel when setting up the UPS.
The 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 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 battery 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.

2.0 NAVIGATING THROUGH THE
TOUCHSCREEN CONTROL PANEL
The Touchscreen Control Panel is active whenever the UPS has input power. The touchscreen
LCD on the front of the UPS permits:
• Logging in to the system—3.1 - Log In to the Touchscreen Control Panel
• Customizing the user interface—2.4 - Customizing the Display
• Checking the status of the UPS and its external batteries, including all measured parameters, events and
alarms—4.0 - VIEWING UPS STATUS and 5.0 - VIEWING UPS COMPONENT STATUS
• Determining when users logged in and out—4.3 - Logs—Events and Log-In Times
• Silencing alarms—3.3.1 - OPERATE Menu—Silence an Alarm
• Turning the UPS On —3.3.2 - OPERATE Menu—Inverter On
• Turning the UPS Off—3.3.3 - OPERATE Menu—Inverter Off
• Resetting faults—3.3.4 - OPERATE Menu—Reset Fault
• Enabling Energy Saving Mode—3.3.6 - OPERATE Menu—Energy Saving Mode Activation
The Touchscreen Control Panel’s display default view is two panes: One-line animated mimic and
UNIT STATUS. The appearance can be changed to multiple panes that show other data.
Customizing the appearance is detailed in 2.4 - Customizing the Display.
2.1 Restrict Physical Access with Barriers or Set Log-In Codes
NOTICE
Risk of unauthorized changes to UPS operational settings. Can cause equipment damage.
Because a UPS such as the Liebert®EXL™S1 is usually installed in areas that restrict physical access, the
Touchscreen Control Panel does not, by default, require a PIN to change UPS settings and operations.
If physical access cannot be restricted with barriers and identity cards, PIN codes may be set in the
Touchscreen Control Panel to prevent unwanted changes to the Liebert®EXL™S1.
The Touchscreen Control Panel has four possible access levels—Observer, Operator,
Administrator and Service—each with different levels of authority. The Service level, which
permits configuration changes, is the only level that, by default, requires a PIN.
The default access level for the Touchscreen Control Panel is Administrator. When a PIN is set for
the Administrator, the control panel opens at the Operator level.
To set or change a PIN, refer to 3.1 - Log In to the Touchscreen Control Panel.

2.2 Touchscreen Control Panel Components
The main areas of the Touchscreen Control Panel are shown in Figure 3. The display
arrangement and the information displayed can be changed.
At log-in for all access levels, the Touchscreen Control Panel opens to the STATUS screen in graphic
display. The status of Unit 0 will be shown if the system is a single-unit configuration. In a parallel
setup, the STATUS screen shows the unit where the HMI is installed or the system view. The STATUS
screen will show the animated mimic and system status readings at each log-in level. The
appearance will differ only in the function menus displayed (see Figure 4).

Figure 4 Control display by access level—if PIN’s are required
Each Function Menu offers different information and control choices.
If PIN’s are not required, the user will see the STATUS, OPERATE, SETUP and LIFE Services
Function Menus.
If PIN’s are required, the user’s access level determines which Function Menu icons are
displayed. For example, logging in as Operator will show the STATUS, OPERATE and LIFE
Services Function Menus; logging in as Administrator will show those menus as well as the
SETUP Function Menu (see Figure 4).
• STATUS: Condition of the UPS modules and components and data affecting operation and performance;
visible at all access levels.
• OPERATE: UPS operation controls, such as Inverter On, Inverter Off and Energy Saving Status; visible to
Operator, Administrator and Service
• SETUP: Manage permissions through PIN’s; visible to Administrator and Service
• SERVICE: Input wiring and breaker configuration, parallel status, protocol used and battery charging
method; visible only to Service
• LIFE Services: Information for assistance to enable LIFE customer care. LIFE Services requires a
maintenance contract. The service must be activated with assistance by calling the listed telephone

2.2.1 Context Menus
The Context Menus, available by touching the Menu icon at the top left corner of the
interface, display information about the UPS and permit changing various settings.
The functions possible through the Context Menus are determined by the user’s
access level and on the Function Menu that is active (see Figure 5).
The items under Display Options on the STATUS Context Menu, for example, differ
for each access level.
Some information available through the Context Menu, such as alarms and run hours, are
available through other areas of the Touchscreen Control Panel.

2.3 SYSTEM PANE—Mimic Display Components
The animated mimic display, the default view for the control, shows each configured major
component of the UPS system, for both single-module and multi-module systems. The mimic
display is the same for all access levels. The power path is shown by animated lines; moving
dashes show the active power path. Touching a component (except a breaker) brings up details
about the component’s status. Breakers are shown as open or closed (see Figure 6), but they are
not interactive.
Components in the mimic display signify their operational status by their color, green, amber or
red. Tables 9 through 11 describe the various states of the indicators.
The animated mimic display can be changed to any of five other views: Status, Alarms, Run Hours,
Event Log and Battery Cycle Monitor Summary (see 2.4 - Customizing the Display).

2.3.1 UNIT STATUS Pane Components
The UNIT STATUS pane is identical for all PIN access levels (see Figure 8), if PIN’s are required.
Observers will not have the edit icon (pencil). In the default graphic view, the UNIT STATUS pane
shows:
• Status Gauge—Connected load shown in kW and as a percentage of capacity; input, output and bypass
voltage for each phase (default data may be changed; see 4.1 - Viewing UPS Data with the Status Gauge).
• Load Detail Icon
•InputDetailIcon
• Bypass Detail Icon
• Battery Detail Icon
The detail icon for Environmental may be added to the UNIT STATUS pane if there is space.
Touching any of the detail icons reveals additional data about that selection in the opposite pane.
The data pane may be closed by touching the Close button or by touching any detail icon. The
read-only information is available to all access levels (see Figures 9 through 13).
