Error 011 Solvent vapor threshold exceeded.
Cause: A leaking cell.
Action: Check for foreign material on the threads of the cap, the seal surface,
and the cell body. If necessary, replace the O-rings and/or seals (see
Section 5.2 ).
Tighten the cell end caps hand-tight. Do not use a wrench or other
tool.
Cause: Incomplete purging of solvent from the cell during the purge cycle.
Action: The optimal purge time varies, depending on the sample cell size (see
Table 3-1) . If you are running a preprogrammed method, create a
custom method with the appropriate purge time. If you are already
running a custom method, edit the method to increase the purge time.
For instructions on editing a custom method, see
Section 3.6 .
Cause: A leak somewhere in the system.
Action: Remove the right-side panel of the ASE 150 (see Section 5.4 ).
Inspect the following fittings for leaks (see Figure 4-1 ): pump
fittings, pump check valves, pressure transducer fittings, pressure
relief valve fittings, static valve fittings, and solvent line fittings. Use
a 1/4-inch open-end wrench (P/N 049452) to tighten any leaking
fittings.
Do not overtighten!
If tightening does not stop a leak, the tubing and fitting assembly
must be replaced. Contact Dionex for assistance.
Action: Pull out the drip tray holder below the oven and check the drip tray. If
the tray contains liquid, remove it from the holder, dispose of the
liquid, and reinstall the tray. Then, remove the collection vessel and
waste bottle from the system. Remove the lower trim panel and
check for leaks near the oven and the AutoSeal mechanism.
Error 012 Clamp plate temperature low.
Cause: The heater cable connection to the power supply is loose, or a heater
component malfunctioned.
Action: Contact Dionex for assistance.
