5 Troubleshooting
• Faulty argon gas electromagnetic valve (Connector came off).
• Faulty mass flow controller connector.
• Faulty mass flow controller.
• Faulty Introduction board.
1446 Error: Aux gas flow rate is too low.
The Auxiliary gas flow rate is below the limit.
Check the flow rate of the auxiliary gas. Also check the pressure of the argon
tank. The following causes are inferred.
• The pressure of the argon tank went down.
• Faulty gas line such as clogging or coming off
• Faulty argon gas electromagnetic valve (Connector came off).
• Faulty mass flow controller connector.
• Faulty mass flow controller.
• Faulty Introduction board.
1449 Error: Spray chamber temperature (H) is too high.
The temperature of the spray chamber (H) has risen abnormally.
Check the temperature of the spray chamber (H) and the flow rate of the
cooling water. The following causes are inferred.
• Decrease of the spray chamber cooling water (Tubing is clogged or came
off).
• Faulty spray chamber connector (Connector came off).
• Faulty spray chamber.
• Faulty Introduction board.
1450 Error: Spray chamber temperature (H) is too low.
The temperature of the spray chamber (H) has abnormally dropped.
Check the temperature of the spray chamber (H) and the flow rate of the
cooling water. The following causes are inferred.
• The temperature of the cooling water is abnormally low.
• Faulty spray chamber connector.
• Faulty spray chamber.
• Faulty Introduction board.
1451 Error Plasma gas MFC zero adjustment malfunction.
The Mass flow controller has failed in zero adjustment.
Check the pressure of the argon tank gas. The following causes are inferred.
• Faulty mass flow controller (Connector came off or internal fault).
• Faulty Introduction board.
1452 Error: Aux gas MFC zero adjustment malfunction.
The Mass flow controller has failed in zero adjustment.
