CARm AFC set point not reached [Error Code:2130 2131 2204 2205]

Cause¶

The pressure or flow rate may have not reached the set value due to the following reasons.

• The gas supply pressure is insufficient.
• There is a leak at the pipe connection.
• The resistance of the supply piping is high (the connected piping is long or the inner diameter of the piping is narrow).

Solution¶

• Check that the set values of the column inlet pressure and total flow are within the " AFC control range ".
• Check that the gas main valve is open.
• Check for any looseness or leaks at the pipe connections.
• Contact your Shimadzu service representative to check the inner diameter and length of used piping.
