Dear all,

I have some problem with Beckman 166 deckman detector. It runs OK until yesterday. When I tried to run sample or preview, there was a box out saying "detector need to be calibrated". Then I check the "calibrate on" from the direct control panel, but the calibration failed. I got different messeges from different tries. The most common one is: "sample side blocked". I also saw a lot "lower limit sw failure". I tried to reset detector, but did not help.

Anyone could help? Thanks a loooooooooooot!

How did you try to reset the detector? Just by switching it off, or did you use the reset-button on the inside (the better choice!)?

Yes, I tried both, but it still does not work. When I open the software I got a messege" Pump 126: Module1: affects normal operation".

This problem happened all of a sudden. I did not do anything unusual and then the other morning I found it is down.

I would check the connections (sometimes un- and replugging cables works to wonders ) , reset the pump (the button on the back side), restart the whole system (things you probably already did) and then try the autoconfiguration option of the software. If all modules are found there.....i'd call the support
