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 tubing connections.
• The resistance of supply tubing is large (since the tubing connected is long or its inner diameter is small).

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 that no tubing connections are loose and there is no leak.
• Contact your Shimadzu service representative to check the inner diameter and length of used tubing.
