Figure 55. Cell Resistance Alarm Levels Setup (MPM)
Cell Resistance Alarm Levels box - To set Alarm Levels on a cell basis, click Individual and
Input Level and select options on this box.
Percentage Above - Sets the cell alarm level a percentage above the selected dataset
levels. Type a value (1 to 99) in the Percentage Above field.
Absolute Above (Microhms) - Sets the cell alarm level a numeric value above the
selected dataset levels. Type a value (1 to 99) in microhms in the Absolute Above field.
Date area check boxes - Click one dataset date in this area on which to base alarm
levels. The system stores the date of the baseline data and displays it on the lower right
after the Apply button is clicked.
Apply - Click apply to apply selected levels to the cells. The values appear in the
Threshold column. If you do not want to edit individual cell levels (see below), click OK.
Cell, Intertier and Threshold columns - To edit individual cell or intertier alarm levels
in the Threshold column, click the value and type a new value. After editing, click OK.
Note: Values are not saved until Save or Send is clicked on the Float Alarms or another
Battery Setup box.
Alarm Thresholds - For high and low cell voltage, overall voltage, temperature, resistance,
and current, select violation threshold values that activate an alarm during a float condition.
These thresholds are deactivated for 30 minutes following a resistance test. If a discharge
occurs, the alarms are disabled until the overall voltage recovers to a value above the low
threshold.
High Cell Voltage Warning (volts) - Type a value between the Low Cell Voltage and High
Cell Voltage levels. This setting affects the bar graph colors on the Cell Voltage String View
screen. During normal float condition, the bar colors change as follows:
High Violation ................... Red
Warning ............................ Blue
Normal .............................. Green
Low Violation .................... Yellow
Out of Range Values ........ Maroon
Negative Cell Voltage ....... Black
