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.

How can one perform AC and DC voltage checks on a Beckman LS6500 Mains Power Supply (PN. 606682) module?
Service AI
Check the video below to learn how to test the voltage output(s) (+5 VDC, +15 VDC, -15 VDC, and +24 VDC) of the Beckman LS6500 power supply module.
This video demonstrates the AC and DC voltage checks on a new style power supply module outside the LS6500 instrument. The same process applies when measuring voltage with the new or old style power supply module mounted inside the LS6500. If the LEDs on the relay board piggybacked on the power supply module (not shown in this video) are all OFF, it is a clear indication that the power supply module is dead.
LS 6500 displays H# abort with 'count rate too low' message.

Make sure the mechanical movement of the source spring that is responsible for the movement of the radioactive source from the pea to the pig is okay and not slipping and unable to move smoothly. If you confirm that the physical mechanical movement is okay, and the problem still persists,

Read MoreMy Beckman Coulter LS6500 CRT monitor is dead. Is there a replacement available?
Service AI
Yes, there is a replacement available, and a good one too!
Our LS6500 READY! Wyse Winterm terminal module is configured to work with Beckman Coulter LS6500 liquid scintillation counters and is the perfect replacement for the obsolete CRT terminals that were originally shipped with the LS6500. The fully tested plug and play module also works with Beckman LS6000 instruments with serial number 7064XXXX or higher and is available at the Service AI webstore. The LS6500 READY! Wyse module ships with a power supply adapter and a cable to connect with the LS6500. Email us at support@serviceai.us, or call us at our technical support line at +1-510-899-1340 for more information.
Installation tips:
Installing the Wyse module for your Beckman Coulter LS6500 is a breeze! This plug-and-play device simply replaces your existing CRT terminal. To get started, remove the old terminal and connect the Wyse Winterm module to the same CRT 25 pin port using the 25/9 pin cable that ships with the module.
Next, connect any available LCD flat screen monitor to the Wyse module using a standard VGA cable (not included in the shipment).
Once the physical connections are complete, it's important to ensure that the Wyse Winterm module is powered on (using the included power adapter) before the LS6500 is powered on and booting up, just as you would with the old CRT terminal.
For more information or assistance with installation, please email us at support@serviceai.us or call our technical support line at +1-510-899-1340.
