Troubleshooting Alarms and Warnings
Allow only qualified personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation.
Use the Troubleshooting codes along with other system manual documentation to complete actions for resolving alarm messages listed in the Activity Log.

Message |
Powder Airflow Low |
Corrective Action VT |
Check if input pressure is greater than 100 psi (6.9 bar). Check for blocked flow tubing to pump. Check wiring for proportional valve VY1B for shorts or opens J5 pins 1,2 and 3 on backplane. Replace proportional valve. |
Corrective Action HD |
Check if input pressure is greater than 90 psi (6.2 bar). Check for blocked powder delivery line to spray gun. Check for blocked powder tubes inside pump. Check if internal regulator is set to 85 psi (5.9 bar) with gun triggered ON. Check for blockage in proportional valve. Check for oil/water contamination. Check for water and/or oil contamination in the transducer filters by removing the board from the flow manifold. Replace filters with filter service kit. |

Powder Airflow High |
Corrective Action VT |
Check if input pressure is greater than 100 psi (6.9 bar). Check for blocked flow tubing to pump. Check wiring for proportional valve VY1B for shorts or opens J5 pins 1,2 and 3 on backplane. Replace proportional valve. |
Corrective Action HD |
Check if input pressure is less than 110 psi (7.6 bar). Check if internal regulator is set to 85 psi (5.9 bar) with the spray gun triggered ON. Check for contamination in the proportional valve. Check for oil/ water contamination. With gun triggered OFF, check that no air is leaking from the pump. If air is leaking, remove the proportional valve and clean it. If air is not leaking, plug the 8 mm powder delivery port and perform the Re-Zero Procedure. Check for water and/or oil contamination in the transducer filters by removing the board from the flow manifold. Replace filters with filter service kit. |

Atomizing Airflow Low |
|
Message HD | Pattern Airflow Low |
Corrective Action VT |
Check if input pressure is greater than 100 psi (6.9 bar). Check for blocked atomizing air tubing to pump. Check wiring for proportional valve VY1B for shorts or opens J5 pins 4,5 and 6 on backplane. Replace proportional valve. |
Corrective Action HD |
Check if input pressure is greater than 90 psi (6.2 bar). Check for blocked airline to spray gun. Check if internal regulator is set to 85 psi (5.9 bar) with gun triggered ON. Check for blockage in proportional valve. Check for oil/water contamination. Check for water and/or oil contamination in the transducer filters by removing the board from the flow manifold. Replace filters with filter service kit. |

Atomizing Airflow High |
|
Pattern Airflow High |
|
Corrective Action VT |
Check if input pressure is greater than 100 psi (6.9 bar). Check for blocked atomizing air tubing to pump. Check wiring for proportional valve VY1B for shorts or opens J5 pins 4, 5, and 6 on backplane. Replace proportional valve. |
Corrective Action HD |
Check if input pressure is less than 110 psi (7.6 bar). Check if the internal regulator is set to 85 psi (5.9 bar) with the spray gun triggered ON. Check for contamination in the proportional valve. Check for oil/ water contamination. Trigger the spray gun OFF and reset the fault. If the fault returns without triggering the spray gun ON, remove the 6 mm blue tubing for pattern air and check for air leaks. Make sure the gun is triggered OFF. Check that no air is leaking from the port of the pump controller. If air is leaking, remove the proportional valve and clean it. If air is not leaking, plug the 6 mm pattern port and perform the Re-Zero Procedure. Check for water and/or oil contamination in the transducer filters by removing the board from the flow manifold. Replace filters with filter service kit. |

Over Current |
|
Corrective Action |
Check for a shorted gun cable. Check for a bad multiplier using a kV Replace cable if bad. Replace multiplier if bad. Refer to the spray gun manual for repair and parts information. |

Over Current Foldback |
|
Corrective Action VT |
This fault can occur if the gun tip touches a grounded part while spraying. This fault turns the electrostatic output OFF. Release the trigger to reset the fault and resume spraying. Resolve the fault on the system controller Activity Log screen. Trigger the gun ON again. If the fault reoccurs, disconnect the spray gun high voltage power supply from the gun cable inside the gun (J2) and trigger the gun ON. Refer to the Power Supply Replacement procedure in the spray gun manual. If the 0x2011u code does not reappear but changes to 0x3010u Gun Open, then check the high voltage power supply for issues. If the help code 0x2011u reappears with the high voltage power supply disconnected, check the gun cable continuity and replace it if shorted. Perform Gun Cable Continuity Tests as described in the spray gun manual. |

If the help code 0x2011u reappears with the high voltage power supply disconnected, check the gun cable continuity and replace it if shorted. Perform the Gun Cable Continuity Tests as described in your spray gun manual. |

Corrective Action |
Make sure kV is set to maximum 100 kV, trigger the gun ON and check the µA display on the system controller screen. If the µA display always reads >75 µA, even when the gun is more than 3 ft from a grounded surface, check the gun cable or the gun high voltage power supply. Refer to the spray gun manual for procedures. |

Gun Open |
|
Corrective Action |
Trigger the gun and check the system controller screen. If the µA feedback is 0, check for a loose gun cable connection at the gun receptacle. Check for a loose connection to the high voltage power supply inside the gun. Perform Gun Cable Continuity Tests as described in the spray gun manual. If the cable and the connections are okay, check the spray gun high voltage power supply. |

Corrective Action HD |
Check the wiring harness connection (J8) to the proportional valve solenoid on the iFlow module. Check the solenoid operation. Replace the valve if the solenoid is not working. |

Corrective Action VT |
Check J4 pin 5 and 6 wiring diagram backplane. |
Corrective Action HD |
Check J4 wiring on the pump manifold. |

Corrective Action VT |
Check J4 pin 1 and 2 wiring diagram backplane. |
Corrective Action HD |
Check J5 wiring on the pump manifold. |

Trigger ON During Powerup |
|
Corrective Action |
This code appears if the gun was triggered ON when the system was turned ON. Turn OFF the system, wait for several seconds, then turn the system back ON, making sure the spray gun is not triggered ON. If the fault reoccurs, check for a bad trigger switch. Refer to the spray gun manual for repair and parts information. |

No CAN Communication |
|
Corrective Action |
Check for loose device controller board. Reseat if necessary. Check for loose CAN connection on mini-backplane J1. Check for poor connection on M12 Device Net Cable on the pump controller. Check for poor connection on M12 system controller cable. If CAN connections are secure but the fault persists replace the cable. Route the network cable away from sources of electrostatics (hopper, gun cables, powder hose). Verify proper grounding. |
