What is a BDS-256XL? The Alber BDS-256XL is a complete battery

diagnostic system well suited for a variety ofmonitoring applications

The BDS-256XL can measure and store thefollowing data

Cell voltage Battery voltage Cell resistance

Ambient and electrolyte temperature Discharge current Float current Battery discharge data


5/455

How Does the BDS-

256XL Work? The BDS-256 is permanently connected to

a battery via sense lead wiring describedlater in this tutorial

The BDS-256 continuously scans key

operating parameters for unacceptabledeviations from defined limits

When a threshold is exceeded, the BDS-256 can be programmed to alert the userwith a number of reporting methods

Introduction The BDS-256XL Battery Diagnostic System

is designed for a variety of batteries of upto and including 256 cells. A single systemcan monitor 8 strings of batteriessimultaneously

The system can communicate using RS-

232, USB, modem and network methodsdepending upon the users requirements

CM-XL8 Function

Each Controller can manage up to 8 strings ofup to 256 cells/channels

The controller holds all system setup

information and test data in non volatile RAM It communicates to the DCMs via visible-light

fiber optic cable

The controller is also the source of low-voltage AC power to additional systemcomponents
