One of my Waters 590 pumps decided to die on me, i.e. the CPU board doesn't start.

Now I need the service manual with the wiring schematics to find and fix the error.

Does anybody have one available?

Thanks!

well... you never know why you never throw certain old things away!
I have an ill 590, and the very old manual. The problem is that it is a very large paper file. What exactly do you need?
The appendix E is in part, a series of electrical blueprints and other dark things...

Oh wow! Thanks!

Would you mind giving me your e-mail address so we determine how you can get the pump to me? I need some arcane electronic parts and the housing for the pump mechanics. The service manual would come in handy as well

The information I need is:
- What voltages does the supply board produce?
- What capacities do the capacitors have?
- Are there different ROM versions?
- How does the oil pump (for the lubrication) of the unit work?
- How is the oil compartment sealed?
- What signals are wired through the backplane board?

And do you have any spares for the 590?

OK, HbJ

Let me tell you that when my 590 breaks down, there is no hope left, or spare parts. My pump still works, (I dont know for how long)

What I can offer you is that I can send you the three schematics in the manual: two for the motor driver and one for the interconnect (hand-made). They are for the user, I am not as skilled as you suppose in the terms you asked , so I have no idea if the answer to what you ask me is there.
