I have an unsupported UR5 CB2 system that has developed an error when running. The error is: C55A52: Safety system error. I am using version 1.6, which has been removed from support. I have tried shutting down and restarting, but after it comes up, the error reappears. Has anyone experienced or heard of this issue that could help by giving me your insight? I am thinking that it is a Universal Robots JM766A Masterboard error/fault but am unsure. I have looked at the manual and it only states that the error is a “C55A52 5V - 3V3 or ADC error - 5V too low”. I am willing to buy a replacement board (new or used) if that is the reason for the fault. I would like to stay with version 1.6 so that I don’t have to try to upgrade the software on the system. Any insights would be greatly appreciated. Thanks in advance. Rick Russell
I have the same problem. I did replace the masterboard and that did not solve the issue. When I look at the logs, I see a message about Wrist 2. Could wrist 2 be causing the 5v loss? Are there any test points or terminals to check that?
Did you replace the masterboard or the safety board? If wrist 2 was drawing too much power (due to load or failure) it could cause the 5v to drop and trigger the safety board I suppose and cause the shutdown. I don’t know about any test points to check. I suppose you could compare 2 wrist joints to see if there is a difference to point you in a direction. Where do I view the log files? I get an error message popup, but if there are logs that might be more detailed, that might help lead me to the proper solution. Where did you find/purchase parts? Mine is a version 1.6 that is handwritten on the safety board. I have found a used version 1.8 board on Ebay, but the only software upgrade available on the software download is for 1.8. I read that you need to upgrade to version 1.7 and then 1.8 to get to version 1.8. Any help or insight you can provide would be very helpful. Thanks!
- Masterboard and Safety Control Board are the same.
In CB2 there’s a motherboard and a masterboard (called Safety Control Board in CB3, yes). - You can retrieve the log file with a magic file found on UR’s download site. It’s a good idea to check it for underlying issues related to the other fualt.
- CB2 parts are no longer available from UR, so you have to be lucky to find a distributor, who has some in stock. I would definitely advise you to consider how much money you want to spend on the robot due to this exact reason - if it breaks again in the future, it will be even harder to fix it.
- You can find legacy software updates here: Universal Robots - LEGACY DOWNLOAD CENTER
It’s correct that you need to update to 1.7 and then 1.8.
If you upload the log file here after you retrieve it, I will take a look at it, too. But, to me, it sounds like it’s a faulty masterboard (SCB). I have replaced a masterboard due to this exact error (C55A52) before, which solved the issue.
Yes, in CB2, Masterboard is Safety Board. That is the board I replaced. I did purchase this on Ebay, and it is 1.8. My board was 1.7, so I did not have to upgrade to 1.7, just 1.8.
The same seller on ebay has the MS-9856 board, however; I have read nothing leading me to believe that this board is related to the issue.
When I boot up, and try to initialize, these are the messages I get on the log tab.
C101A0: Real Robot Connected
C100A3: Robot changed mode: Initializing
C184A4: Joint self test not completed: Wrist 2
C100A4: Robot Changed Mode: SECURITY STOPPED
Wrist 2 C55A52: Safety System Error: 5V, 3v3 or ADC error (5V too low).
I believe that since the Masterboard did not fix the issue, and Wrist 2 comes up, it may be causing the issue. Still troubleshooting.
So how do I retrieve the log file? If I knew where to find it I could make a copy to my USB drive. I see the utility to use to view it that you load on a windows pc.
If I buy a masterboard that is version 1.8, do I have to upgrade the software to 1.8 or is it backwards compatible? Would the 1.6 software still function?
If I can retrieve the log file, I will upload it so you can take a look.
I really appreciate your expertise!
As I said already, you need a magic file to retrieve the log file. The magic file can be found on UR’s download page.
“Magic file” doesn’t say much, I guess, but it’s a file you put on a USB drive from your PC and then insert the USB in the UR Teach Pendant or controller, and it will then retrieve the log file and store it on the USB.
Magic file: https://www.universal-robots.com/download/software-e-series/support/magic-files/magic-file-backup-log-history-file/
Leave the USB in the robot for 30 minutes or so. It’ll take a while for these old robots.
There are two models of the masterboard. If you’re getting a newer model, you might have to update as far as I remember. Though, if it’s coming from a robot, it’s most likely the old model. So you won’t have to update.
Are you sure, it’s saying Wrist 2 in front of the message? That looks weird. Can you grab a screenshot of it?
I have not seen it associated with a joint before. So it could very well be the joint that’s failing, as you’re saying yourself.
Yeah. Haven’t seen that before, sadly.

I’m honestly not sure what it means, when it says a component in front. 
But yours could look like a fault in the Teach Pendant.
I don’t see the “a component in front” in the logs I posted. Are you looking at my uploaded text?
So do you think replacing the masterboard will resolve my issue?
I honestly don’t know. It sounds more like the same issue sales1 has observed.
It’s a fifty-fifty between the masterboard and teach pendant in my eyes.
