Programming Battery Setup for the MPM
17-8
Percentage for Warning - Determines the violation threshold that causes a Warning battery
status. The value entered is a percentage of the internal resistance alarm. For example, if the
internal resistance alarm is set to 100 microhms and the percentage for warning is 75%, the
system issues a warning when the internal resistance is between 75 and 100 microhms. When
the value exceeds 100 microhms, the system issues an alarm. Warning status is displayed
only on the String Status and Historical Events screens, not on the Alarms screen.

Latch - When selected, the alarm contact stays energized until manually reset. If not selected,
the alarm contact de-energizes when the alarm condition clears.
Remote Reporting - When selected, causes the monitor to report the alarm. When not
selected, call-out is disabled for that parameter. You must select this option and Remote
Reporting Enable under Setup|Battery|General to enable the call out function and to display
Alarm Detail on the Historical Events screen during polling.
