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 High
The
AC Voltage
is above the
AC High Threshold
. See System Alarms on page
AC Low
The
AC Voltage
is below the
AC Low Threshold
. See System Alarms on page
AC Phase Rectifier Missing
A rectifier assigned to an ac phase (see details on page
) is not registered.
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".
All Rectifiers Shut Down
All rectifiers have been shutdown by the SC100.
Aux. Temp Sensor Fail
The Auxiliary Temperature sensing system is faulty, or the I/O board mapping is
incorrect.
Aux. Temperature High
The Auxiliary Temperature sensor is at a temperature above the Auxiliary
Temperature High Threshold.
Aux. Temperature Low
The Auxiliary Temperature sensor is at a temperature below the Auxiliary
Temperature Low Threshold.
Battery Characterization
Error
The percentage deviation between the calculated values and the configured values of
battery characterization is more than 20%. See Battery Characterization on page
Battery Characterization Fail
The Battery Characterization process has stopped because either:
the battery current is unstable, or
the Battery Fuse Fail alarm is active, or
more than one rectifier has failed, or
the bus voltage or the battery current cannot be measured.
See Battery Characterization on page
Battery Charge
Over-current
The battery charge current is above (Battery Charge Over Current Threshold *
Battery capacity) or 2A, which ever is greater.
Battery Current Limit
Battery Current Limit (BCL) is active. See Battery Current Limit on page
Battery Fuse Fail
A battery fuse has blown or a battery circuit breaker has operated (indicated by an
active digital input with
Function "
Battery Fuse Fail").
LBRS is automatically suspended if the Battery Fuse Fail alarm is active.
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
Battery Test Fail
The batteries do not have the required capacity or are not fully charged. See Battery
Test on page
