6.2 Messages on the Pump Display

Each time a fault or error occurs during the operation of the SRD, the Status LED or the
Status and Vacuum LEDs on the front panel door change to red. If the SRD is operated
from the pump of the UltiMate 3000 system, one or more messages appear on the pump
display. When the pump is operated from Chromeleon, the message also appears in the
Chromeleon Audit Trail.
The table lists SRD-related messages along with recommended remedial actions. In addition
to the messages in the table, other messages may appear. In this case, write down the exact
wording of the message and contact Thermo Fisher Scientific Service for Dionex HPLC
Products if you are unable to eliminate the problem.
Message
Degasser malfunction.
Solvent Rack leak detected.
Tip: For information about the messages related to the pump, see the Pump and/or
NCS/NCP manual.

6.3 Chromeleon Diagnostics Message

When the degasser in the SRD fails the Degasser Vacuum Test, the degassing module
most probably did not reach the appropriate operating vacuum.
Check the tubing of the vacuum system and the degassing module and repeat the test. If the
test fails again, the degassing module may be defective and should be replaced.

Remedial Action
The vacuum level monitoring function of the degasser in the SRD was
activated. Turn the SRD off and on again by pressing the standby
button on the front panel. Contact Service if the message appears again.
The leak sensor in the SRD has reported a leak. There is a leak in the
system or a fluid connection is loose. Locate the source for the leak,
eliminate the cause, and dry the leak sensor (→ page 47).
