Fault Types
There are three types of fault messages: automatic faults, manual faults, and
escalating automatic faults. Table 4-3 describes how they differ in their behavior
and how you can respond to them when they appear on the XW System Control
Panel.
Inverter Operation After Faults
XW Inverter/Charger operation changes when a fault occurs. How the operation
changes depends on the operating state of the unit when the fault occurred—
inverting, charging, grid or generator support, AC bypass, and so on—and on
which fault has occurred.
Table 4-3 Fault Types and Behaviors
Fault type Behavior
Automatic faults Clear automatically if the fault condition that generated the
message goes away. You can also acknowledge automatic faults
without waiting for them to clear automatically.
Manual faults Require you to clear them by:
•
selecting Clear Faults on the Main XW Inverter/Charger
menu or on the menu for the Xanbus-enabled device that
generated the fault (if the fault condition still exists, the fault
message reappears)
• correcting the condition that caused the fault.
Escalating automatic
faults Clear automatically if the fault condition goes away, just like an
automatic fault.
However, if an escalating automatic fault occurs several times
within a defined time period, the escalating automatic fault
becomes a manual fault, requiring user intervention. For
example, if an AC Overload fault occurs three times in five
minutes, it will no longer clear itself and become a manual fault.
Then you must identify the problem, correct the fault condition,
and clear the fault.
Table 4-4 Inverter Operation After Faults
Faults State when Faults Occur Action After Faults
F1, F2: AC Output Inverting Unit stops inverting and waits for
nominal AC output voltage level,
or a manual clear from user.
F3 to F10: AC1 Input
Voltage and Frequency AC1 input is the
preferred source and
qualified. Unit begins inverting (if inverter is
enabled) or disengages AC1 and
waits for nominal AC1 input (if
inverting is disabled).
F11 to F16: AC2 Input
Voltage and
Frequency. AC2 input is the
preferred source and
qualified. Unit begins inverting (if inverter is
enabled) or disengages AC2 and
waits for nominal AC2 input (if
inverting is disabled).
