Liebert STS2 Touch Screen Display

13.3Mimic Display

The Mimic display provides a color diagram of the operation of the Liebert STS2. This display imi- tates 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 48 on page 85.

13.4Event 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.

13.5Event Display

The Event Display lists the condition of the Liebert STS2 in real-time. Both nominal system parame- ters 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.

13.6Menu 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.

13.6.1 Configuration Menu

When you select the CONFIG (Configuration) menu choice, a pop-up menu is dis- played 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 of these choices accesses a separate dialog box.

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 sys- tem is initialized at the factory or under maintenance and should not be changed by the user.

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.
