13.3 Mimic Display
The Mimic display provides a color diagram of the operation of the Liebert STS2. This display imitates the power
flow through the static transfer switch and indicates source status, breaker status, switch status, source voltage
and current readings, output power measurements, and active alarm messages. See Figure 44 on page 82.
13.4 Event Controls
The Liebert STS2 detects events when certain thresholds are passed or certain problems occur. The alarm
controls allow you to acknowledge the existence of these events.
• RESET — All latched events whose conditions have cleared are removed from the Event Display. Faults and alarms that
remain active, or are not recoverable, are not affected when this button is selected. This button is also used to perform
manual I-Peak resets and manual retransfers.
• SILENCE — turns Off the audible alarm (horn or beeper) without resetting the triggering event. This setting does not
permanently turn Off the horn. The alarm sounds again when the next event with an audible alarm setting is triggered.
Active events are shown in the Event Display, whereas cleared events can be reviewed via the Event Log.
13.5 Event Display
The Event Display lists the condition of the Liebert STS2 in real-time. Both nominal system parameters and alarm
messages are displayed in the Event Display. You can touch any message in the Event Display to display more
information in the Display Panel to the left. The selected status is displayed in bold type.
13.6 Menu Bar
As previously mentioned, the menu bar provides both configuration choices and information. The choices under
the Config and Log menus access additional dialog boxes, while the other menu choices only show information
in the display panel.
13.7 Configuration Menu
When you select the CONFIG (Configuration) menu choice, a pop-up menu is displayed with
four choices.
• System Ratings — used to configure frequency, voltage and currents settings for the Liebert STS2.
• Event Mask — allows you to configure system’s response for events.
• User Settings — allows you to configure operations for the Liebert STS2.
• System Settings — accesses another pop-up menu to configure communication and system choices
and the system ID.
Each choice accesses a separate dialog box.
13.7.1 System Ratings
The System Ratings menu is used to set the nominal line frequency, nominal voltage and
nominal current at which the system operates when it is installed. These settings are configured when the
system is initialized at the factory or under maintenance and should not be changed by the user.
13.7.2 Event Masks
The Liebert STS2 gathers, processes and reports faults and alarms, collectively referred to below as events. The
Event Mask dialog box allows you to set the system’s response for specific alarms and faults that are generated.
See 11.0 - Alarm and Faults for more information on events and 11.1 - Event Mask for the definitions of the
Event Mask types.
