DetAPCn DCG set point not reached [Error Code:2144 2145 2146 2147]

Cause¶

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

• No column is connected.
• 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 column is connected.
• Check that the gas main valve is open.
• Check that the gas supply pressure is within the range below.
  
  

  
• Check that the supply pressure is sufficient for the detector gas to flow.
  
  

  
• 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.
