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.
