5 Troubleshooting
2404 Warning: Cooling water temperature is low.
The temperature of the cooling water is below the limit.
Check the temperature of the cooling water. When the setting of the cooling
chiller is not correct or faulty, this error may be generated.
2405 Warning: RF Driver voltage is high.
The voltage of RF Driver exceeds the limit. It is possible that the output power
of the RF generator is not controlled properly.
The following causes are inferred.
• The value of the RF Matching (Tuning Parameter) is inappropriate.
• The matching network box or the work coil is abnormal.
• Faulty Matching Network Box.
• Faulty RF generator.
2412 Warning: Plasma gas flow rate is low.
The flow rate of the plasma gas is below the limit.
Check the flow rate of the plasma gas. Check the pressure of the argon tank.
The following causes are inferred.
• The pressure of the argon tank fell.
• Gas line fault 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
2413 Warning: Aux gas flow rate is low.
The flow rate of the auxiliary gas is below the limit (When the instrument is
changing from Standby Mode to Analysis Mode).
Check the flow rate of the auxiliary gas. Check the pressure of the argon tank.
The following causes are inferred.
• The pressure of the argon tank fell.
• Gas line fault 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.
2414 Warning: Carrier gas flow rate is low.
The flow rate of the carrier gas is below the limit.
Check the flow rate and the pressure of the carrier gas. Check the pressure of
the argon tank. The following causes are inferred.
• The pressure of the argon tank fell.
• Gas line fault such as clogging or coming off
