ERROR MESSAGES
This table includes a listing of the faults that might be generated by the controller, 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. The second
column lists a short description of the condition. The third column shows whether the condition will cause a Hold, or
Lockout, or both. The fourth column lists some suggestions for corrective action.
