Battery
diagnostic systems (BDS) continuously monitor all critical battery
parameters, verify the integrity of the connected battery system,
and alarm on any out-of-tolerance condition. Testing includes proactive,
internal DC cell resistance measurements at programmed intervals
recommended by IEEE standards. By tracking increases in internal
cell resistance, the BDS predicts if the battery system will perform
during a power outage.
The BDS-256XL Battery Diagnostic System
The BDS-256XL is a modular system that can
monitor virtually any UPS battery configuration. The BDS-256XL consists
of a Controller, Data Collection Module, and Resistance Test Module.
Interface
to the BDS-256XL is done using the Alber Battery Monitor Data Manager
(BMDM) software. The Battery Monitor Report Generator program creates
reports from collected data.
The
CM-XL8 Controller
The
Controller, the brain of the system, coordinates alarms and traffic
to and from the other system components. It can monitor up to eight
strings of 256 cells on independent UPS's, for a total of 2048 cells
per Controller. Its nonvolatile memory can hold up to a year's worth
of data. The built-in power supply provides 24VAC for all components
in the system.
The
DCM-XL48 Data Collection Module
The
Data Collection Module (DCM) is a scanning voltmeter that acquires
overall voltage, cell voltage, current, and temperature readings
from the monitored battery string. The DCM can monitor cells or
blocks from 1V to 16VDC. The DCM compares captured data with preset
thresholds and alerts the user if any parameters are in violation.
Each DCM can measure up to 48 cells or battery blocks per string.
DCM's can be connected in series to monitor up to 256 cells per
string. The DCM also controls the load module during a resistance
test.
The
RTM-XLR Resistance Test Module
The
Resistance Test Module (RTM) provides the load during the patented
resistance test. Without this component, the monitor system could
not provide the high reliability and repeatable results that Alber
customers rely on.
The BDS-256 System Features
•
Monitor up to 256 cells/modules per string. 2V cells, NiCd
cells, 4V, 6V, 8V and 12V modules are supported.
• Overall voltage, cell/module voltages, current, and
temperature are continuously scanned and compared with programmed
alarm levels.
• Internal DC resistance tests are performed and compared
to programmed alarm levels. All data is saved.
• Overall voltage, cell/module voltages, current, and
temperature readings are saved.
• Discharges are detected and data saved. All parameters
are scanned every four seconds during a discharge.
• Discharges can be viewed in real time locally or remotely
during the discharge event or later replayed in real or accelerated
time.
• Alarm events trigger an indicator, dedicated contact
closure, programmed contact closure, and dial-out notification.
All battery parameters can be set to page, fax, print, and/or sound
an alarm.
•
Communication via network, modem, serial or USB. Optional
TCP/IP interface for network or Internet communication. Industry
standard MODBUS protocol interfaces to third party, building management
systems.
•
No on-site computer required.
•
Modular design easily expands to monitor an unlimited number
of strings. When used with the MPM-100, virtually all battery configurations
can be managed with one software package.
• Digital input/output option permits monitoring up to
16 inputs and up to 8 user-programmed outputs.
• Monitor Load Control option enables the monitor system
to control an Alber Continuous Load Unit (CLU) for performing battery
capacity testing.
• Automatically poll and retrieve data.
• Reports can be e-mailed and then viewed using the free
downloadable Alber Archive Reader.
• Faulty cells detected during an unplanned discharge
event can be reported in real time.
•
All components are standard 19" rack mount.
