Hello  I have two Avanti J25 centrifuges,the old style with the rotary knobs and the led displays, one works fine but the other displays "sys drive" I have swapped all the circuit boards from the good one to the faulty one but errors still there, can anybody help please ? thanks Phil

I am in the UK, If no one can point me in the right direction will contact them, I think it might need calibrating but cannot find any info on this model, thanks for replying Phil

Based in the Northwest, the centrifuges are in storage at present in Bolton , Phil.

Are you looking to get theM both up and running and in use again,?

A "SYSTEM" diagnostic usually requires a complete initialization of the centrifuge. I previously posted ALL of the steps required to do this for all Beckman Avanti J series centrifuges on this data base. First, however, you need to know which SYSTEM and DRIVE diagnostics you have. Again, I previously posted the necessary steps to download the error codes, too. The drive diagnostic may or may not actually be the drive motor assembly or one of the electronic assemblies. Either way you still need to know what the error codes actually are before proceeding. I worked on them for 17 years before retiring from Beckman Coulter and what I posted is right out of the service manual. Get back to me after you have the codes and we can proceed from there.

OK, the "S7" is indeed a situation that will require a complete reinitialization of the centrifuge. That in itself may "fix" your "D1" problem but no guarantees on that. The D1 is indicative of a failure of one of the 3 RPT's (rotary position transducers)located in the bottom of the drive motor assembly. That failure could also be generated by a failure of the circuit board that monitors the RPT's. That would be the smaller circuit board located on the swing out chassis. The easiest way to see if the board is functional is to rotate the drive spindle by hand and see if the 3 LED's on that board are turning off and on as you do so. Again, going thru a complete initialization as I previously posted on this data base may take care of the D1 problem AFTER it takes care of the S7 diagnostic. Hope this helps.

thanks for the information Don, is there any information on this forum of how to do a complete

reinitialization ? or do i need an engineer

Yes, I posted the complete process for both the LED display and the fluorescent display models at least 2 or 3 years ago. You will have to search in this data base as it is an involved process and you MUST follow all of the steps including entering the correct altitude for where you are located in order to not have FRS (vacuum) problems.

Sorry Don only read the top part of your reply, I am reading on my phone did not show full reply, thanks for this information will check the leds tomorrow,your information is greatly appreciated

No problem Phil. Just let me know how it goes and understand, there are only certain rotors that can be used for the initialization process so let me know which rotors you have available to do the process.

If you currently work for Beckman Coulter then you should realize that what you are doing is against company policy. Your call but I have no issues since I retired almost 8 years ago. Just be careful that no one in corporate finds out what you are doing.

Having trouble finding the initilization process for the led model, I have read all the posts on here can you point me in the right direction ? thanks Phil.

Phil, It should be somewhere in the area of the fluorescent display posting. It is rather involved so reposting it would kind of be a pain.

thanks for the help Don I checked the RPT leds like you have said in previous posts and they did not flicker when the rotor was spun,I removed the drive and found that the RPT circuit board area was full of water, I dried everything and reinstalled, now the leds work fine, but still cannot find the info to initilize the centrifuge, I have read all your posts and googled for information but to no avail, could someone help me find your previous post, I feel I am almost there fixing this machine, thank you

Water in the bottom of the drive motor is indeed a problem. The drive and tubing assembly was redesigned about 8 years ago to eliminate this as an issue. I don't know if they issued an update kit for that and I really have no way of finding out anymore. I will try later today, US east coast time, to repost the instructions that you are unable to find so by tomorrow you should be good to go.

Sorry that I did not get back to you but I had a medical issue to deal with. I will dig out my manual and repost the the instructions.

First, you never told me what rotors you had available to you because that will determine if all of the initialization steps can be done with your rotor(s). Also, there should be a decal behind the front cover of the centrifuge affixed to the frame of the centrifuge. You should find ALL of the pertinent settings on that label UNLESS you changed out circuit boards from the ones that were originally installed in the centrifuge. So, instead of having to run a dynamic initialization you could simply plug in the values on the label for each section.ALL commands start with the sequence [SET/ACTUAL], [ACCEL], [SET/ACTUAL], [DECEL]. then it just a question of the next two key selections as to what information you want to enter into the centrifuge. The first item is to clear the S7 diagnostic. That is done by entering [TIME/HOLD], [ACCEL] after the previous 4 steps mentioned followed by the [CLEAR] button.If the door lock timer EVER gets engaged, use the [TIME/HOLD], [DECEL], followed by [CLEAR]to override it.To clear a system lock-up, enter [RPM/RCF], [TIME/HOLD].Next is the ELEVATION of where the centrifuge is located. Again, this should be on the calibration label. So after entering the steps previously mention, press [ACCEL] and then [DECEL] within 2 seconds of each other. Enter the value and hit the[SET/ACTUAL] key to store the value.Next, enter the P2 value off of the label by hitting [DECEL], [RPM/RCF] within 2 seconds of each other followed by the [SET/ACTUAL] key.In order to do a complete initialization enter [RPM/RCF], [DECEL] then press [START] AFTER THE DOOR IS CLOSED! The speed display should show 4500 RPM and then the centrifuge will run thru both the "INERTIA" and "WINDAGE" calibrations during which time the centrifuge will start and stop several times all under automatic control. DO NOT hit the STOP button or you will abort the sequence.If you only want to enter the necessary drive values then do the following:For the 900 to 1900 RPM Inertia value enter [ACCEL], [RPM/RCF] and dial in the value on the decal into the speed display using the speed knob. Press [SET/ACTUAL] to store the value.For the 3000 to 3500 RPM inertia value press [ACCEL], [TIME/HOLD], dial in the value in the speed display followed by [SET/ACTUAL] to store the value.Finally, enter the Windage Calibration value by pressing the [ACCEL] key twice within 2 seconds in the speed display followed by the [SET/ACTUAL] key to store the value.That should get you going again assuming that there is nothing else wrong with the centrifuge. I apologize again for not getting back to you quicker but I have been dealing with some issues that made even sitting at my desk problematic. Please let me know how it goes.Don
