Chapter 6 - The PowerView Display
The PowerView Display
The PowerView Display is the primary user interface for the SymmetraTM Power Array system. It is used to control the Power Array, to configure the functionality, monitor the sys- tem, set alarm thresholds, and it performs as the audible and visual alarm.
Physical Features of the Powerview
The PowerView Display incorporates a 4 x 20 LCD with four navigation keys, four LED lights, and an audible alarm beeper. It is designed to either mount on the front of the frame, to stand on top of the frame, or to be installed at a remote loca- tion. A local RJ45 connector cable is hardwired to the top power module bay (L1), and is used to connect the display when it is mounted onto the frame. A 20’ RJ45 cable is pro- vided with the system for positioning the PowerView at a re- mote location.

PowerView Functions
An overview of each of the PowerView interface functions is provided below:
νUser Interface - The PowerView is the primary user in- terface for the system. It is used to command the system to power up, and power down the load, as well as to check the status of system components, and to configure the functionality of the system.
νAlarms and Alarm Thresholds - The PowerView con- tains an audible and visual alarm system. In the event of a power disturbance, or loss of a system component, (and other
As an example, if a Power Array has been configured with an N+1 redundancy, the PowerView can be configured so that an audible alarm will sound if the system looses the redundant power module. (Typically, this would be the result of an additional load being added, or a power mod- ule failure.) Other user configurable alarms include load size threshold and minimum runtime threshold. Proce- dures for setting user configurable parameters are pro- vided in Chapter 7. All PowerView display messages, and the corrective actions are listed in Chapter 9.
νSet System Function Parameters - The PowerView can be used to set parameters for the functioning of the Power Array. These include acceptable input and output fre- quency ranges, frequency of self tests, and minimum/ maximum settings for power transfers.
νPowerview Interface Parameters - The PowerView can be used to set the contrast of the LCD screen, select the information that is displayed in the startup screen, set the time, date, password and the audible alarm volume.
νEvent Logging - The last 64 power and user events are recorded and accessible via the PowerView interface. The category of events that are logged is configurable. Statis- tics are compiled and can be reviewed using the PowerView.
νCheck Status and Diagnostics - Input voltage, output voltage, available runtime, load size, current operating mode and the status of each power and battery module are reported by the PowerView interface.
νTesting - The PowerView interface can be used to per- form a system self test and to simulate a power failure.
νHelp Function - Pressing the up and down navigation keys simultaneously launches context sensitive help.
