Battery Monitor Data Manager Demonstration 2004 DIEBOLD POWER SOLUTIONS LLC

Welcome Thank you for taking the time to view this Battery Monitor Data Manager (BMDM) software demonstration. This presentation was created to give you a quick overview of the BMDM program. In the next few minutes, you will see some of the key features this program has to offer.

This presentation When a battery monitor is purchased from Albér, there are always two software programs included - at no additional cost! This presentation covers the Data Manager software, but does not include the Report Generator software, which can be demonstrated separately. Sit back and enjoy!

String Status Screen When the BMDM program starts, the String Status screen is displayed. Normally, this screen is waiting for a monitor to call in with an alarm to report or is waiting to perform automatic polling of all strings. This screen shows the latest status of all strings as well as monitor hardware status as of its last automatic poll. This screen is completely customizable with typical spreadsheet functionality.

String Status Screen - Names Each entry on the status screen represents a string, identified with a Customer, Location, Battery and String name. With this naming convention, there is no practical limitation to how many strings can be monitored. The string ID, assigned by the software, is mainly used for identification for digital pagers. The Customer name could identify a specific region or district if used within one company. Strings with the same battery name indicate multiple strings in parallel.

String Status Screen - Status ®2002 Two types of status are displayed: String Status and Battery Status. Simple status phrases are displayed for easy interpretation. These status messages are updated primarily by two methods: (1) The program automatically polls each monitor on its designated interval, and (2) A monitor calls the program to report an alarm event. The Date/Time shows the actual time the status was updated.

Status Summary ®2002 Selecting this button will display a summary of the current status of all the strings and monitors.

System Setup ®2002 Setting up a new string or editing an existing one is easily accomplished by selecting this icon or double clicking on the desired string in the list. But before doing this, a valid password must be entered. The customer information is displayed below.

System Setup - Link The Link tab under System Setup allows the connection type to be defined for each individual string. Some battery monitors may have a network connection available, while others may only have a telephone or serial connection. This is especially useful when dealing with multiple customers who have different network infrastructures. ®2002

System Setup - Reporting The Reporting tab identifies what action will be taken when an alarm event is reported from a string or monitor in trouble. The alpha pager enables the sending of a complete description of the alarm event and the current status of the string in alarm. ®2002

String Status – Comm. Status Communication status shows what’s occurring at that time. For example, the program could be answering a trouble call from a battery monitor. Let’s follow the steps to see what happens when an alarm is being reported.

String Status - Alarm reporting ®2002 Once the call has been answered, a dialog box similar to this one identifies the exact reason of the fault. The Status at the lower left indicates what is taking place as a result of the alarm event. This could be a page to service personnel, faxing or printing a report, or just sounding an audible alarm.

String Status – Historical Alarm button ®2002 After the event has been reported, the alarm status icon flashes to indicate a new event has occurred and has been recorded in the Historical Events Log. Selecting this icon lets you enter the Historical Events log to view the complete history of all the events.

String Status – Historical Alarm Events ®2002 The Historical Events Log shows past and present alarms and lets you see the complete alarm detail description. The default view shows the latest alarm event at the top, but you can create custom views for your specific needs.

String Status – Ready to Connect ®2002 Clicking on a string from the list and then clicking the Connect button (above) lets you connect to the battery monitor and view the system in real time. This allows you to respond immediately as a first line of defense to the alarm. This connection can be made from any location, providing the physical connection (modem or network) is available. Typically, this interrogation is made by service personnel who were notified by one of the automatic reporting features.

String Status – String View Connected! When viewing a site in real time, you will see bar graphs that represent each cell/module within the string. As this screen shows, the yellow bar indicates the low threshold was violated. At the lower left, note the red text for the Float Current reading. This indicates the parameter has violated a high threshold and could possibly indicate a thermal runaway condition.

String Status – String View – Trending menu You can perform a complete trending analysis on any parameter measured by just right clicking over the desired parameter and selecting Trend from the menu. Let’s look at the entire history of cell 12.

String Status – String View – trending analysis Here is the entire history of cell 12. Selecting the left and right arrow keys lets you scroll through the other cells within the string. Each data point within the trend represents data recorded by the monitor on a scheduled time. Clicking on these data points will display a separate dialog box that indicates the date/time and actual value.

String Status – String View – other buttons You can enter additional screens by selecting these shortcut tool buttons. For example, clicking the button displays another screen showing internal resistance measurements. The button shows detailed screens on alarm information, and the and buttons show discharge information. On some monitors, the button becomes active, letting you view intercell connection resistance. Let’s enter the internal resistance screen.

String Status – String View – Internal Resistance This graph represents the internal resistance measurements of each individual cell or module. These types of measurements are becoming the industry standard for predicting battery reliability. The red bar displayed here is without question a bad cell. To understand more about the theory of internal resistance measurements, click the following selection: Predicting Battery Performance Using Internal Cell Resistance .

String Status – String View – Internal Resistance Trend This is the trend graph of this faulty cell. The point where the cell begins to show an increase in resistance would have generated an alarm. This increase is typically gradual and gives adequate time to respond before the situation becomes significant enough to cause a serious outage problem.

String Status – String View – Discharge Entry Now let’s look at the discharge logging capability. Selecting this button will display a discharge hit record.

Discharge Hit Record This screen shows a complete list of all discharges, with ability to sort on any parameter. Selecting a specific discharge allows detailed information to be viewed. Let’s take a look!

Discharge Pre-Playback This screen allows a real time or elapsed playback of the discharge event. The bar graphs show all the cell voltages decay as the discharge time advances.

Discharge Pre-Playback This section shows a line graph of the discharge current. When playing back the discharge, a red line will advance from left (time 0) to right in increments defined in the playback setup. The next slide shows a playback of this discharge in 3 minute intervals.

Discharge Playback Discharge Playback in Progress –Stand by!

Discharge – Faulty Cell The cell that failed the discharge test is the same cell that had the high internal resistance. Although you can not directly correlate the amount of capacity (in percent) with internal resistance measurements, they are still extremely useful for identifying faulty cells.

String Status – Discharge Detail Graphs Selecting the Line graph button allows viewing up to three parameters, for a quick analysis of a particular parameter. Further details and reports can be created using the Report Generator. Line graph of a good cell during the discharge you just viewed. Line graph of a the bad cell during the discharge you just viewed. See how it decays quicker than the good cell (above).

Thank You Thanks for letting us demonstrate this overview of the Battery Monitor Data Manager (BMDM) software package. Keep in mind, this presentation only touched on a portion of the program’s capabilities.
