Operating Instructions
Fluorescence Detectors FLD-3100 and FLD-3400RS
Remedial Action
Verify that the flow cell is properly installed. Open and close the front
panel door. Turn the detector off and on again by pressing the power
switch on the rear of the detector.
Turn the detector off and on again by pressing the power switch on the
rear of the detector.
Remove the flow cell. Turn the detector off and on again by pressing the
power switch on the rear of the detector. If the error occurs again with the
flow cell installed, contact Service.
Turn the detector off and on again by pressing the power switch on the
rear of the detector.
You cannot select both PMTs (PMT1 and PMT2) for excitation scans.
Select either the standard (PMT1) or the infrared (PMT2) PMT.
The leak sensor has reported a leak. Check the flow cell for indications of
leakage. Retighten leaking connections if necessary. Dry the leak sensor
(→ page 113).

The firmware download failed. Repeat the firmware download.
Verify that the flow cell is properly installed. The lamp is automatically
turned off when a flow cell is missing.
The detector is not calibrated. Verify that a flow cell is installed correctly
and that the eluent composition in the flow cell does not change and no
air bubbles are present. Then open and close the front panel door.
Signal overflow. Repeat the scan with a lower sensitivity.
The qualification interval will expire after the number of days indicated
in the message. Perform a qualification.
The qualification interval has expired. Perform a qualification.
The detector was unable to perform autoranging (the automatic reduction
of the sensitivity when the detector becomes saturated), as the Sensitivity
was changed manually at the same time.
The detector had to automatically reduce the Sensitivity. Select a suitable
Sensitivity (→ page 81) and repeat. The Chromeleon Audit Trail shows a
warning, in which x indicates the new sensitivity value after the
adjustment. Use this value in your method when you expect similar
concentrations.
The Sensitivity was changed manually during autoranging (the automatic
reduction of the sensitivity when the detector becomes saturated).
