Agilent 7500 Series ICP-MS Hardware Manual 5-49
• Faulty argon gas electromagnetic valve (Connector came off).
• Faulty mass flow controller connector.
• Faulty mass flow controller.
• Faulty Introduction board.
2415 Warning: Makeup gas flow rate is low.
The flow rate of the makeup gas is below the limit.
Check the flow rate of the makeup 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.
2416 Warning: Optional gas flow rate is low.
The flow rate of the optional gas is below the limit.
Check the flow rate and the pressure of the optional gas. Check the pressure of
the optional gas tank. The following causes are inferred.
• 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.
2433 Warning: Air intake temperature is high.
The temperature of intake port located at the rear side of the instrument
exceeds the limit.
Check the inlet temperature. The following causes are inferred.
• The temperature near the intake port increased due to the heater.
• Intake port is clogged.
• Faulty intake temperature sensor or System I/O board.
2435 Warning: Exhaust temperature is high.
The temperature of exhaust duct exceeds the limit.
Check the exhaust temperature. The following causes are inferred.
• A shortage of the duct flow rate.
• Sampling cone is not tightened enough.
• Faulty exhaust temperature sensor or System I/O board.
2605 Warning: Y- axis Torch position is outside the warning limit.
The Y- axis torch position moved beyond the warning limit.
