7 - 25 Feature Descriptions Issue 13 February 2001
Parameters The energy management feature may be enabled via the T1.317
interface or from the front panel. The energy management enabled
parameter shows the state of the hardware and software DIP switches for
energy management. The energy management state shows the state of
the energy management algorithm (e.g., the algorithm could be enabled
by both DIP switches, but disabled due to a Battery on Discharge
condition.)
History Logs The history logs allow the user to record a number of alarms and events
that occur in the system, including rectifier state history, battery
discharge history, boost history, and login history. The user can control
history log reports by specifying chronological order, specific alarms/
events, grouping similar alarms, or by limiting the report to events
between specific dates. When history logs are clear in whole or part, the
history logs cleared alarm becomes active. The history logs may be
viewed and cleared from the local port, modem port, auxiliary port, or
front panel.
Alarm History Alarm history maintains a record of the date, time, and severity of
critical, major, minor, warning, and record-only events. An entry is
added to the history when an alarm occurs and when an alarm retires.
The table below defines how many entries are retained for plant alarms,
user defined events, and other alarms.
# of entries
Plant Alarms 256
User Defined Events 256
Other Alarms 64
Normally alarm history entries are reported in order from the newest
entry to the oldest entry. However, from the access ports entries for the
same alarm can be grouped together, the report can be limited to a
specific range of dates, the entries can be ordered oldest first, and the
report can be limited to specific alarms. The history report includes the
following information:
identifier A mnemonic that uniquely identifies the alarm
date Date entry was made
time Time entry was made
severity Alarm severity (critical, minor, major, warning,
record-only)
description A short description of the alarm.
