5 Troubleshooting
• The orifice of the sampling cone is too big.
• The seal of the sampling cone is incomplete (Defective O- ring).
• The plasma is too far from the sampling cone.
• The power of the rotary pump is not connected or the breaker is OFF.
• The rotary pump oil level is low or the oil is dirty.
• The vacuum tubing has failed (the tubing is off, or a leak is caused by an
incomplete seal such as a pin hole or a defective O- ring).
• A drop of water was introduced into the vacuum chamber.
• The vent valve is not closed or the seal is incomplete.
• The cover of the vacuum chamber is not closed or the seal is incomplete.
• There is a leak in the gate valve.
• There is a fault in the Penning gauge or the System I/O Board.
• The reaction gas flow rate is too high.
2153 Warning: Analyzer Vacuum is too high.
The vacuum pressure (AN) exceeds the limit (In Standby Mode).
Check the vacuum pressure (AN). The following causes are inferred.
• The power of the rotary pump is not connected or the breaker is OFF.
• The rotary pump oil level is low or the oil is dirty.
• The vacuum tubing has failed (the tubing is off, or a leak is caused by an
incomplete seal such as a pin hole or a defective O- ring).
• The vent valve is not closed or the seal is incomplete.
• The cover of the vacuum chamber is not closed or the seal is incomplete.
• There is a leak in the gate valve.
• There is a fault in the Penning gauge or the System I/O Board.
2400* Warning: Cooling water (IF) flow rate is low.
The flow rate of the cooling water (IF) is below the limit.
Check the flow rate of the cooling water. The following causes are inferred.
• The power of the cooling water chiller is OFF.
• Cooling water valve is closed.
• Cooling water is insufficient (possibility of a water leak).
• Cooling pipes are clogged or leaked.
• Cooling water strainer is clogged.
• Cooling chiller is faulty.
2400* Warning: Cooling water (RF/WC/IF) flow rate is low.
The flow rate of the cooling water (RF/WC/IF) is below the limit.
Check the flow rate of the cooling water. The following causes are inferred.
• The power of the cooling water chiller is OFF.
• Cooling water valve is closed.
• Cooling water is insufficient (possibility of a water leak).
• Cooling pipes are clogged or leaked.
• Cooling water strainer is clogged.
