Restart Without Cover - Agilent Technologies 1200 Series Reference Manual

Restart Without Cover

The quaternary pump was restarted with the top cover and foam open.
The sensor on the LPM board detects when the top foam is in place. If the
quaternary pump is restarted with the foam removed, the quaternary pump
switches off within 30 s, and the error message is generated.
Probable Causes
• The quaternary pump started with the top cover and foam removed.
• Rear of the module is exposed to strong direct sunlight.
Suggested Actions
