9. TROUBLESHOOTING

XFiire Error Codes

If any of the sensors detect an abnormal condition or an
internal component fails during the operation of the XFiire,
the display may show the error. This code may either
be the result of a temporary condition in which case the
display will revert to its normal readout when the condition
is corrected, or it may be the result of a condition that the
controller has evaluated as not safe to restart the unit.
In this case, the unit control will be locked out, requiring
the maintenance person to manually reset the control by
pressing and releasing the button.
Error messages are displayed in touchscreen. For
additional error details please refer to the VERSA IC
control manual (5000.72).

Heater Errors

When an error condition occurs, the controller will display
an error code on the touch screen display. These error
codes and several suggested corrective actions are
included in the XFiire Fault Text section on the following
page.

Heater Faults

1. When a fault condition occurs, the controller will flash
a red light on the PIM and display the error code on the
user interface. The alarm output will also be activated.
Most fault conditions will also cause the heater pump
to run in an attempt to cool the unit.
