Battery Total Discharge Time The cumulative battery discharge time
Battery Volts at Main Disconnect
The voltage between the positive and the negative battery terminals of the
common battery disconnect
Battery Volts for Cabinet
The voltage between the positive and negative battery terminals of a
battery cabinet
Bypass - Excess Auto Retransfers
The number of auto retransfers, from bypass to inverter, has exceeded
the maximum for a specified time interval
Bypass - Manual Rexfr Inhibited Manual transfer from bypass to inverter is inhibited.
Bypass - Manual Xfr Inhibited Manual transfer from inverter to bypass is inhibited.
Bypass Auto Retransfer Failed
After performing a recoverable transfer to bypass, an attempt to auto
retransfer from bypass to inverter failed
Bypass Auto Transfer Failed An automatic transfer to static bypass failed
Bypass Excessive Pulse Parallel
The system has performed too many pulse parallel operations within a
specified time interval
Bypass Frequency Error The bypass frequency is outside the inverter synchronization limits
Bypass Input Frequency The bypass input frequency
Bypass Input Voltage RMS A-B The bypass input RMS voltage between phases A and B
Bypass Input Voltage RMS B-C The bypass input RMS voltage between phases B and C
Bypass Input Voltage RMS C-A The bypass input RMS voltage between phases C and A
Bypass Isolation Breaker (BIB) Bypass isolation breaker (BIB)
Bypass Nominal Voltage Bypass nominal (or rated) voltage
Bypass Not Available A problem associated with the bypass has been detected
Bypass Overload Phase A An overload exists on output phase A while operating on the bypass
Bypass Overload Phase B An overload exists on output phase B while operating on the bypass
Bypass Overload Phase C An overload exists on output phase C while operating on the bypass
Bypass Qualification Status bypass qualification status
Bypass SS Overload Time Remain
The calculated time remaining before bypass static switch shutdown due
to the present overload condition
Bypass Static Switch Off Extrnl Bypass static switch is off due to the state of an external signal
Bypass Static Switch Overload Bypass off due to static switch overload
Bypass Static Switch Unavailable The static bypass switch is off, and unable to operate
Bypass Sync Phase Difference
The phase angle difference between the inverter output and bypass
source
Controls Reset Required A controls reset is required due to one or more critical settings changing
DC Bus Current
The current at the battery input terminals. In charging mode, the current
will be a positive value. In discharging mode, the current will be a negative
value
DC Bus Ground Fault - Negative A ground fault has been detected on the negative DC Bus link
DC Bus Ground Fault - Positive A ground fault has been detected on the positive DC Bus link
DC Bus Qualification Status dc bus qualification status
DC Bus Voltage
The voltage between the positive and negative terminals of the DC bus at
the battery input
Equipment Over Temperature Equipment over temperature summary event
Equipment Temperature Sensor Fail
One or more temperature sensors report a temperature outside of the
range of expected operation.
Fuse Failure A summary event indicating one or more fuse failures
Inlet Air Over Temperature The inlet air exceeds the maximum temperature threshold
