Alar m D escriptions
AC Fail
All rectifiers report ac supply failure or a digital input with Function set to "AC Fail"
is active.
AC Phase 1/2/3 Fail Phase 1/2/3 of the ac input has failed, i.e. it deviates from the Nominal AC Voltage by
more than the AC Phase Fail Threshold . Only available in systems where ac phase
voltage is measured.
AC Phase 1/2/3 Voltage Phase 1/2/3 of the ac input deviates from the Nominal AC Voltage by more than the
AC Phase Voltage Threshold . Only available in systems where ac phase voltage is
measured.
ACD Fan Fail The ac distribution cooling system or fan controller has failed (indicated by an active
digital input with Function set to "ACD Fan Fail".
Battery Current Limit Battery Current Limit (BCL) is active. See Battery Current Limit on page 28 .
Battery End of Life If Battery End of Life date has been set, then this alarm will activate when that date is
reached.
Battery Fuse Fail A battery fuse has blown or a battery disconnect device has operated (indicated by
an active digital input with Function " Battery Fuse Fail").
Battery Temperature
High
The analog input with Function set to "Battery Temperature" has a value above the
Battery Temperature High Threshold .
This alarm indicates either thermal runaway of the batteries or that the batteries are
operating at a temperature that may cause reduced battery life.
Battery Temperature
Low
The analog input with Function set to "Battery Temperature" has a value below the
Battery Temperature Low Threshold .
This alarm indicates a risk to the standby power system battery as lower
temperatures reduce the battery capacity.
Battery Test The Battery Test control process is active. See Battery Test on page 30 .
Battery Test Fail The batteries do not have the required capacity or are not fully charged. See Battery
Test on page 30 .
Cabinet Fan Fail
A cabinet fan has failed (indicated by an active digital input with Function set to
"Cabinet Fan Fail").
Characterizing Battery The SC300 is running a battery characterization, which is a full depth test battery
discharge. See details on page 73.
Configuration Error
One of the following is true:
•
The Rectifier Current Limit is set higher than the Maximum Current Limit of all
the registered rectifiers. See details on page 42.
•
The OVSD Set Point is out of the range of any registered rectifiers. See details on
page 42.
•
More than one digital output are mapped to the same relay on an I/O board or
SiteSure-3G Module. See details on page 90.
•
An LVD contactor is in Conflict state. See details on page 53.
•
Smart Alarm Based Disconnect is Enabled , but the corresponding Smart Alarm is
Disabled . See details on page 53.
•
A Smart Alarm source has an invalid Source Triggered setting.
