23.12. Alarm Data
String View > View alarm or View|Alarm
The MPM or BDS monitor constantly checks threshold values set under Battery Setup. As
long as alarms are enabled, the monitor creates a record of thresholds violated. Click
View Alarm to display alarm screens.
String View > View alarm or View|Alarm then, if not displayed, Get current alarms
or View|Current Alarm
The Current Alarms screen indicates Active or Latched for the alarm contacts. Active
indicates a parameter is presently violating a threshold. The screen displays the alarm name
and start time. Latched indicates the parameter returned to normal, but the alarm relay must
be reset. The end time indicates when the alarm event changed to a latched state. Peak Value
lists the highest or lowest value reached during the event. For latch to function, enable the
latch under Battery Setup for each parameter. If latch is not selected, the alarm contact
de-energizes when the parameter returns to normal. A record of a present alarm is saved as a
Current Historical Alarm.
Figure 105. Current Alarm List
String View > View alarm
or View|Alarm then Reset alarm or View|Reset Alarm
When you select Alarm, active or latched alarms in the monitor are retrieved. These alarms
stay active until the condition clears or you click Reset Alarm. However, if you click Reset
Alarm and the violation still exists, the alarm reappears in the Current Alarm list.
String View > View alarm
or View|Alarm then Get current historical alarms or
View|Current historical alarm
The Current Historical Alarm screen displays alarms that reset or cleared on their own and
were not set to latch. Select Current Historical Alarm to retrieve the alarms still in monitor
memory. Normal indicates the alarm returned to a valid value on its own. No reset date or
time is displayed. If an alarm exists and it is reset, an entry is created in Current Historical
Alarms at the reset time, and a new alarm is created because the alarm condition still exists.
Reset indicates a latched alarm was reset. The reset date and time column indicates when the
reset occurred. Peak Value lists the highest or lowest value the parameter reached during the
event. When you select Current Historical Alarm, data is transferred from the monitor to the
database and saved under Historical Alarms. If you select Current Historical Alarm using a
Central computer, the current history data is permanently removed from the monitor.
