unknown alarm lamp on Dionex Pulsed Electrochemical Detector

[janjac1981]

Hi all

I have a Dionex Pulsed Electrochemical Dector that doesn't work properly.
The baseline started fluctuating wildly.
I am pretty sure it is not the electrochemical cell thats the problem (tried different cells - same result)

On top of the device is a alarm lamp, which is on. The manual doesn't say anything about the meaning of this lamp. See images below, for the location of the lamp:





Does any one have any thoughts or good ideas ?

best regards

Good morning! Unfortunately I can't see the pictures, but according to my experience of work with Dionex some ideas appeared.
1) Does the pump work properly? Baseline fluctuation is usually caused by problems with the pump.
2) Alarm button is on when, for example, plug is disconnected or there's a leak in the electrochemical cell.

But once again, baseline fluctuation (if it's regular) gives an idea to check the pump.

Sincerely yours, Elena.
