Sorry about the duplicate but I posted most of this in the manual request section of the forum.
Skooter has been helping, thanks a lot.
I will summarise the work so far in getting my IRB 2000 working and then continue posting as I hopefully get to the bottom of the problem.
I first posted:
I have an IRB2000 with an old S3 controller and also looking for as much documentation as I can get. I am looking for wiring diagrams and service manuals if possible. I have searched about and most of the links on this forum seem to be quite old and expired.
At the moment every board on the controller has a red error light including the CPU. Not sure where to start?
I am trying to confirm what pins on X3 should be strapped to ensure that the external safety interlocks are disabled at the moment until I get it working.
Another thing I noticed is the NiCad battery pack seems to have leaked and I assume its not working.
Looking for details on what I should be looking for on the various test pins on the VME bus boards, voltage or oscilloscope waveforms?
Skooter helped out with manuals and guidance:
IRB2000s were built from 1987-93. I like to call the M87-M90A "Old S3" and the M91-M93A "New S3". Because of the major changes between old S3 and new S3, please supply the model year designation (M87-M93A) or the serial number.
Whenever resurrecting old equipment, always verify the power supply as some of the main components in them deteriorate with age.
Since it has a DSQC215 CPU, it's either an M90 or M90A controller with an external axis. The M90 power units are YB560101-Gx, the M90A are YB560101-Lx. There was an M90A/2 but I don't remember what changed.
Make sure the 3-position mode switch on the CPU is in the RUN position.
Check the voltages at the test points on the front of the DSQC211 power supply. I remember the 24V was always high which was normal.
I tried posting a Product Manual for the M90 IRB2000 but the forum gives me an error. It is a 6.8MB PDF.
Try searching 'M90' in only the ABB section & Manuals ... child board of the forum. There are other similar posts.
I will now start posting the steps I have been taking.
Once again thanks.
