4.1 Error Messages
The ASE 100 Moduleware can identify several potential operating problems. If
one of these problems occurs, an error message is displayed on the screen. The
message remains until you press any key to clear it or until another error message
appears.
Each error message is identified by a number. This section lists the error messages
and explains how to respond if an error occurs. Most problems can be resolved by
the user.
Error 001 Oven compression pressure low.
Cause:
Insufficient nitrogen gas pressure applied to the oven
compression system during an extraction.
Action: Check the nitrogen supply; if it is low, replace it. Regulate the
supply to between 1.03 and 1.38 MPa (150 and 200 psi);
1.03 MPa (150 psi) is recommended.
Action: Check the
REGULATORS
screen (see Section C.2.3). When
the oven is compressed, the
COMPRESSION
field should read
0.90
±
0.03 MPa (130
±
5 psi); if it does not, adjust the
pressure regulator for the compression oven.
Action:
If the error message appears again, contact Dionex for
