| F10 | Intake Motor Run Feedback The intake drive lost its run status or failed to indicate it was running after receiving a run command. | YELLOW |
| F11 | Exhaust Motor Run Feedback The exhaust drive lost its run status or failed to indicate it was running after receiving a run command. | RED |
| F12 | Intake Damper Position The intake damper failed to indicate an open position while the booth was operating outside of cure mode. | RED |
| F13 | Burner Air Flow The burner airflow switch failed to prove airflow within the set time or unexpectedly lost its proven status. | RED |
| F33 | Fire Alarm The fire alarm input is indicating an active alarm condition because the okay signal was lost. | RED |
| W01 | Over Temperature The booth temperature exceeded the setpoint plus the over temperature tolerance for the programmed time, triggering a warning. | RED |
| W02 | Under Temperature The booth temperature dropped below the setpoint minus the under temperature tolerance for the programmed time, triggering a warning. | GREEN |
| W03 | Burner Unlit The burner failed to ignite within the set time or unexpectedly lost its flame, causing the heating system to fault. | RED |
| W04 | Burner Air Flow The burner airflow switch failed to prove airflow within the set time or unexpectedly lost its proven status. | GREEN |
| W05 | Recirc Damper Position The recirculation damper failed to indicate a closed position, triggering a warning level alert. | GREEN |
| W06 | Fresh Air Damper Position The fresh air damper failed to indicate an open position, triggering a warning level alert. | GREEN |
| W07 | I/O Force(s) Active An input or output is currently being forced on the programmable logic controller, triggering a warning. | RED |
