Programming Battery Setup for the BDS
18-17
Note: If using the Current Mode, the minimum threshold Level to detect discharges must
be at least 5% of the current transducer (CT) rating. For example, if the CT rating
is 600A, the minimum Level is 30A.
Voltage mode allows data recording during recharge, since data logging does not stop
until the voltage goes above the threshold. If measuring discharge current, use
Discharge Current Mode as a reliable source of trigger.
To enable current mode, you must define the Current Channel on Setup|Battery|
Parameters in the DCM# column.
Report All Discharges - If selected, the monitor reports all discharges to the Central
computer. You must enable Remote Reporting on Setup|Battery|General.
Report Problem Discharge Only - If selected, the monitor reports only discharges that
exceed voltage or time values set in Problem Discharge Thresholds (described later) to the
Central computer.
Disable - If selected, stops the BDS from reporting a discharge.
Deviation Storage Thresholds Area - This feature does not apply to the BDS.
Problem Discharge Thresholds Area:
Low Cell Voltage, Low Overall Voltage, and Maximum Discharge Time - Select the
voltage or time levels that trigger discharge reporting. To enable these values, select
Report Problem Discharge Only on this screen. This setting also affects the bar graph
colors on the Cell Voltage String View screen. During a discharge, the bars change color:
Normal Condition .......................................................................... Green
Problem Discharge Thresholds or Low Cell Voltage .................... Yellow
Time to Go Area:
The String View screen can display a Time to Go (TTG) number. When a BDS discharge
starts, the TTG box on String View indicates the estimated remaining time that the
battery can deliver power. To disable this feature, leave the Amp Hours and Peukert
Number boxes at zero.
IMPORTANT NOTE: The TTG Time to Go number is only an estimate.
Amp Hours - Type the amp hours of the battery at the 8 hour rating. To disable the
estimated time feature, set to 0.
Peukert Number - Type the Peukert number derived by using Peukert's equation. Refer
to Understanding the Time to Go Algorithm. To disable the estimated time feature, set
to 0.
