Chapter 6 - The PowerView Display
The PowerView User Interface
The PowerView is the primary user interface for the Power Array system. It is used to control the Power Array, to config- ure the functionality, monitor the system, set alarm thresh- olds, and it provides audible and visual alarms for the sys- tem.
Physical Features of the Powerview
The PowerView interface incorporates a 4 x 20 alphanumeric liquid crystal display (LCD), four navigation keys, four light emitting diode (LED) indicators, 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 up to 6.1m (20') away. A short RJ45 cable is hardwired to the top right module bay of the frame. This cable con- nects to the PowerView when it is mounted onto the frame. A 6.1m (20') RJ45 cable is provided for remote installation of the PowerView.

PowerView Functions
An overview of each of the PowerView interface functions are provided below:
nUser Interface - The PowerView is used to command the system to power up, and power down the load equip- ment, to review the status of modular and system com- ponents, and to configure functionality of the system.
nAlarms and Alarm Thresholds - In the event of a power disturbance, or loss of a system component, (and other
nSet 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.
nPowerView 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 volume of the audible alarm.
nEvent Logging - The 64 most recent power and user events are recorded and logged into the PowerView in- terface. The interface can be configured to log a specific set or range of data. This data, as well as compiled statis- tics can be reviewed using the PowerView interface.
nCheck Status and Diagnostics - Input voltage, output voltage, available run time, load size, the present operat- ing mode, and the status of every module in the Power Array frame can be reviewed using the PowerView inter- face. (See Chapter 7.)
nTesting - The PowerView interface can be used to per- form a system self test and to simulate a power failure.
nHelp Function - Pressing the up and down navigation keys simultaneously launches context sensitive help.
*For example, a Power Array with an N+1 redundancy can be configured to emit an audible alarm if the system incurs the lose of a redundant power module. (Typically, this would be the result of additional load being added, or a power module failure.)
