Appendix 1 - Error Codes
This table includes a listing of the faults that might be generated by the controllers, and displayed on the Operator Interface. Some
of these can be corrected by an installer changing a parameter, while other conditions are more complicated, and will require a
service technician.
The rst column lists the code number that will appear at the beginning of the Lockout or Hold message in the orange bar at
the bottom of the screen. The second column lists the text as it will appear on the Operator Interface. The third column shows
whether the condition will cause a Hold, or Lockout, or both. The fourth column lists some suggestions for corrective action.
