5 Troubleshooting
• 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.
1119* Error: Vacuum pressure (IF/BK) is too high to open gate valve.
The gate valve cannot be opened because the vacuum pressure (IF/BK) exceeds
the limit or the vacuum pressure (IF/BK) rose abnormally (When the
instrument is changing from Standby Mode to Analysis Mode).
Check the vacuum pressure (IF/BK). The following causes are inferred.
• The diameter of the hole in 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.
1120* Error: Vacuum pressure (IF) is too high to stay in Analysis Mode.
Analysis mode cannot be maintained because the vacuum pressure (IF)
exceeds the limit (In Analysis Mode).
Check the interface line pressure. The following causes are inferred.
• The diameter of the hole in 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.
1120* Error: Vacuum pressure (IF/BK) is too high to stay in Analysis
Mode.
Analysis mode cannot be maintained because the vacuum pressure (IF/BK)
exceeds the limit (In Analysis Mode).
Check the vacuum pressure (IF/BK). The following causes are inferred.
• The diameter of the hole in 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.
