Indication
Steady red
A failure is preventing operation. If, after you cycle power to the solvent
manager, the LED remains red, report the problem to Waters Technical
Service.

3.4.2.3 Detector LED
An LED on the detector’s front panel indicates the run status of the lamp or detector. For
detectors equipped with a lamp, the LED is a steady-green color when the lamp is ignited. For
detectors that are not equipped with a lamp, the LED is a steady-green color when the detector is
operating normally.

Description
Unlit
If the detector is equipped with a lamp, the lamp is extinguished. If the
detector is not equipped with a lamp, the detector is idle.
Steady green
If the detector is equipped with a lamp, the lamp is ignited. If the detector is
not equipped with a lamp, the detector is operating normally.
Flashing green
The detector is initializing or calibrating.
Flashing red
An error stopped the detector's operation. Refer to the console log for

Steady red
A failure is preventing the detector from operating. If, after you cycle power to
the detector, the LED remains red, report the problem to Waters Technical
Service.
3.5 Monitoring from control panels
You can monitor the sample manager, solvent manager, column module, and detector from
control panels, which you access via the chromatography data system.
