They do apply, the reds and the greens are two independent systems, so a red fault will not affect the green leds.
This is very useful to know, the manual is not clear on this subject. Thank you very much!

Here is the RJ-2 red light district :
Thank you for taking the time to check the LED meanings!
We have also looked at this but we have a bog doubt whether they apply. On our CPU, the four green lights are on and stay on even when the reds one(s) turn. The manual is clear enough on this subject, my understanding is that the hints given in the manual apply to situations where the green leds are off.
We will replace the CPU as soon as we manage to load the system on the spare CPU that we just bought.
It looks like there is a CPU card communication problem. I don't think there is a problem with the software inside the card itself.
Thanks!
One of the things we want to check as soon as we have some time is whether the 5 VDC is clean.
We will place an oscilloscope (in single shot, triggered mode) on the 5VDC power line going to the CPU and look for drops... I will inform you on the results.
Make sure NOT to reseat the memory card, it will wipe it!
The memory card is a small daughter board on the main board.
We haven't touched any of the modules on the CPU board. The battery was connected at all times when we reseated the CPU board itself.
From what I read in the R-J2 controller maintenance manual the CPU board has the following daughter boards:
Flash ROM module
CMOS RAM module
DRAM module
3 axis modules
From what I understand the CMOS RAM module is the one that's powered by the battery.
Are you suggesting that we should reseat the other modules?
Thanks!
Hi flbu,
When I search on my computer, these documents come out. dec. Are you looking for one of these?
Hi byrol,
Sorry for missing your message back in February, my notifications were not correctly set up and I did not check the forum since then.
Meanwhile we have obtained from a different source the second document from your list, Some of the following documents appear to be for R-J3.
I am interested in the first document and the last two of your list, if you can send them to me.
Thank you!
A few more updates on this old thread:
We tried to back up the system using kfloppy but the transfer hung up.
Hoping that a faster backup using SRAM card will be more successful we purchased the necessary hardware (memory card reader and two SRAM cards) and then tried again. The backup hangs up again, all three red ALARM lights turn on.
We have also purchased a replacement CPU board but it doesn't have any software. We hoped that we will be able to load the content of the present CPU but this appears to be a dead end at this point (we do not have floppies).
Any ideas or suggestions?
The obvious thing to do would be to load a fresh system.
Does any of you have a S-420 iF compatible tool that we can try to install?
It does not need to be Sealing Tool, Handling Tool would be just fine.
We contacted the local Fanuc representatives but they seem to be overloaded, they have been very slow to reply to recent contacts.
I have never encountered that before, is that part of another package? For instance, DispenseTool use to be independent, but it is now part of SpotTool.
Do you have access to Fanuc's website?
If you can post a .zip of your backup, that could help a lot.
No access to the Fanuc site. Is this access something that can be easily obtained?
From what I can understand SealingTool appears to be one of the major tools for R-J2, on equal footing with HandlingTool and ArcTool. But I am not an expert.
We haven't done yet a backup, we want to make sure we follow the proper procedure before attempting it. Once we have it I will try to share it with you.
I have a manual, but it is a german version.
Will that help you ?
Yes please! The German version is not ideal for us but better than nothing. Thanks!
Sealing Tool.
Thanks!
Hello everybody,
I would greatly appreciate a copy of the setup and operations manual for the Sealing Tool in a R-J2 controller.
Thank you for your attention,
Florin
Update: Reseating the connectors of the CPU board hasn't fixed the problem.

Dear Erik and kluk-kluk,
Thank you very much for your replies !
Below I will try to answer the questions of Erik and then and ask for further advice regarding the backup of the system.
While in bmon the controller/pendant does not hang up.
We have tested again today and this time waited for 20 minutes. The teach pendant remained responsive.
We have done yet another cold start, no change.
Updated info: the time before hanging up can be longer sometimes, up to four minutes recently.
Unfortunately we do not have any copy of the software that came with the system.
Sealing Tool is not something that is important for us but we do not have anything else.
Handling Tool or any other tool that is compatible with S-420iF would be fine for us if we could get a copy...
Meanwhile a backup of the system is on top of our list of things to do and the next question we wanted to ask was whether we can attempt a backup in these conditions. The fact that it does not hang up in bmon is reassuring but I do not know how much we risk if we go ahead with the backup before we have fixed the problem.
If I understand well kluk-kluk then we should go ahead with the backup. Is that right?
We will reseat the connectors to the CPU board and we will inform you on the result.
While here I have a question regarding the backup. I know that it can be done using kfloppy and a serial cable but we are tempted to buy a PCMCIA interface for R-J2 and an SRAM card. There is no interface in the controller but I found about this while reading this forum. This would make the backup a much faster operation (and less risky maybe).
Do you know whether the PCMCIA interface is readily recognized by the controller?
Or do we need additional software from Fanuc for it to be recognized?
Thank you again for your help and attention,
Florin
Hello,
We have recently purchased an old Fanuc S-420iF robot with an R-J2 controller and we have at least a problem with it. We know that we could contact Fanuc or a specialized company but their intervention would cost time than the double or triple of what we have paid for the robot and, as a family company struggling to start, we do not have the money at this stage. It is a also good opportunity for us to learn more about our robot.
The system boots up correctly (with some faults, notably the SRVO 062, because the batteries were depleted) and we can navigate the menus. However, in 1-2 minutes after power on the whole system hangs up: the teach pendant does not respond anymore (without a specific message of any sort) and a red LED (the one of the right) lights up on the main CPU board.
The teach pendant/controller hangs up regardless whether we navigate the menus or just let it wait.
It is very important to
note that it does not hang when started in bmon (boot monitor).
We have done a COLD START but this hasn't fixed the problem.
The image below shows the status of the main CPU board LEDs in the hung up state.
The green LED-s are on since the end of the initial tests. According to a version of the "FANUC Robotics SYSTEM R-J2 Controller Maintenance Manual" that we found on the internet, they indicate that “If the robot’s status is normal, all the status LEDs will be lit.” According to the same manual, the status and alarm LEDs indicate that the main CPU board passes (before the teach pendant is ready to display) successfully a number of tests regarding the CPU PC board, the memory modules and the axis module. Which tells us that these modules should be ok. Unfortunately this manual does not say what happens to the alarm LEDs after the teach pendant is ready to display. We guess that it is the software (Sealing Tool for this controller) manual that presents that.
We do not have any Sealing Tool manual so we would grateful for any help in fixing this problem.
For your reference:
Sealing Tool 7D60
Software Edition No. V4.30P/88
Teach Pendant 7D01/09I
Boot Monitor version 4.22P (01E)
We would be equally grateful for a manual of Sealing Tool/R-J2.
Thank you for your attention,
Florin
