USING THE RATE FEATURE (ANALOG
CHANNEL MAXIMUM LOAD PERCENTAGES REPORT)
This feature determines how plant (battery and rectifier) capacities and other sizing limits
(fuses, circuit breakers, and wire sizes) are faring under actual load conditions. This
feature allows the customer to easily determine the maximum load percentage (that has
occurred) versus an analog channel alarm limit. This feature divides the maximum peak
value of an analog input and the highest hourly average into a designated alarm limit and
presents the results as percentages. These percentages inform the customer how close
a channel's peak and high hourly average values are in relation to its alarm limit(s).
To use this feature, one of two character phrases must appear in the analog channel's
alarm limit name. These two phrases are "CAP" (for capacity) and "SIZ" (for size). Also,
the "Unit Text" for this analog channel must be "AMPS".
To get a report, enter the command RATE. Any time the RATE command is entered, and
either of the two phrases mentioned above appear in an analog channel's alarm limit
name and the analog channel's Unit Text is set for AMPS, the system computes the two
percentages and displays the resulting information. The RATE command is available to
a user programmed for access to level 1 commands. Refer to "Chapter 3. Commands"
for a typical screen display.
VIEWING AND CLEARING THE ALARM LOG
The alarm log maintains in battery-backed memory a chronological listing of the 500
latest alarms that have occurred in the system (and an MCA, if connected). Entries in the
log automatically include analog, function, and binary alarms, however; a relay or LED
channel may be programmed to record an entry in the log whenever it energizes or
illuminates, respectively.
VPS MCA Alarms:
VPS MCA alarms that are recorded in the alarm log are as follows.
For proper system alarm reporting or individual user alarm reporting of VPS MCA alarms,
refer to Table 2-1 and ensure that the desired channels automatically mapped to
predetermined VPS MCA alarms are programmed for system alarm reporting and/or
added to the appropriate user configuration.
System High Voltage Alarm #1 Subsystem Minor Alarm

LPS MCA Alarms:
LPS MCA alarms that are recorded in the alarm log are as follows.
For proper system alarm reporting or individual user alarm reporting of LPS MCA alarms,
refer to Table 2-2 and ensure that the desired channels automatically mapped to
