Beckman LS6500: A Troubleshooting Guide for Elevator Jams
Service AI
Are you experiencing an issue with your Beckman LS6500 where the rack, especially the mini (blue) rack, is not stopping at the correct position, thereby causing the elevator to jam up?
This can occur when the instrument incorrectly identifies the mini (blue) rack as a maxi (standard white) rack and attempts to move the vial up into the detector.
When such a problem arises, it is most likely that the mini rack is not being correctly identified by the Mini/Maxi sensor board.
The Mini/Maxi sensor board (Beckman P/N. 500726) is only installed on LS6500 models that have the versa-rack option. It is very unlikely that your LS6500 counter does not have this option.
Most often, when this sensor board malfunctions, it fails to recognize the mini rack, which causes the instrument to misalign the rack, thereby causing the elevator to jam up. Under such circumstances, users will also notice that they do not experience elevator jam issues when they are using Maxi (standard white) racks on the instrument.
