The following system alarm parameters can be configured.
Parameter
Description
Where to find:
Severity
Set to the required alarm priority. This
determines how the alarm is indicated. See
If set to
Disabled
then the alarm will not activate.
SC300: Alarms > Alarm
Settings (tab) > System
Alarm. Select an alarm.

Alarm States
DO Mapping A
If required, select a digital output (relay) that
will be operated when the alarm is active.
DO Mapping B
If required, select a second digital output (relay)
that will be operated when the alarm is active.
Send Trap
Depending on this setting, an SNMP Trap will be
sent for this alarm, on activation or deactivation
or both, if the alarm's Severity matches the
setting of the SNMP Trap Level (see details on
page 107).
Notes
Type any required description. When the alarm
is active the text will be displayed on the SC300
and included in the SNMP trap (if used).
The notes can provide instructions about what
action to take when the alarm occurs.
Recognition Period The following alarms have individual
recognition periods: AC Fail, System Overload,
Generator Fail.
All other system alarms either use the standard
Alarm Recognition Period or do not have a
recognition period. See details on page 56.

The following alarms have a high or low
threshold: High Float, Low Float, High Load,
Low Load, Battery Temperature High, Battery
Temperature Low.
The alarm will be activated if the measured
value is above or below this value, as applicable.
Enable High Float
Tracking
If enabled, the High Float alarm threshold will
be increased when the operating voltage is
increased by a voltage control process.
Enable Low Float
Tracking
If enabled, the Low Float alarm threshold will be
decreased when the operating voltage is
decreased by a voltage control process.
Battery
Temperature
Alarm Thresholds
The thresholds for Battery Temperature High
and Low alarms are configured here.
AC Alarm
Thresholds
Used in three phase systems, where the rectifier
phase is known.

AC Phase 1/2/3 Fail and AC Phase 1/2/3
Voltage alarms have % deviation thresholds
from the
Nominal AC Voltage
. For each of these
alarms, a common threshold applies for all
phases.
