12.3 Troubleshooting Table
This table includes a listing of the faults that might be generated by the controllers, and displayed on the
Touch Screen. 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 first 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 Touch
Screen. The third column shows whether the condition will cause a Hold, or Lockout, or both. The fourth
column lists some suggestions for corrective action.
