TROUBLESHOOTING
XPak FT Error Codes
If any of the sensors detect an abnormal condition or
an internal component fails during the operation of the
XPak FT, the display may show an error code. This
code may either be the result of a temporary condition
in which case the display will revert to its normal read-
out 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 con-
trol will be locked out, requiring the maintenance
person to manually reset the control by pressing and
releasing the RESET key.
Heater Errors
When an error condition occurs, the controller will dis-
play an error code on the display module. These error
codes and several suggested corrective actions are
included in the XPak FT Fault Text section on the fol-
lowing 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 boiler pump to run in an attempt to cool
the unit.
2. Note the error code, either through the flash code
on the PIM and/or from the Toolbox menu on the
user interface, and reference the explanation of
the fault along with troubleshooting steps in the
XPak FT fault text section.
3. Press and release the RESET key to clear the
fault on the user interface and resume operation.
Be sure to observe the operation of the unit for a
period of time to ensure correct operation and no
reoccurrence of fault code(s).
WARNING: When servicing or replacing any
components of this unit be certain that:
• The gas is off.
• All electrical power is disconnected.
DANGER: When servicing or replacing components
that are in direct contact with the water, be certain
that:
• There is no pressure in the boiler. (Pull the release
on the relief valve. Do not depend on the pressure
gauge reading).
• The boiler water is not hot.
• The electrical power is off.
