Dear listers
A friend of mine who repairs underground equipment has sent me a black box- its part number is:
6489 - 02
3185 5002 85
and is manufactured by Atlas Copco. It is located
between the position sensors and the displace unit
(the machine is underground drilling).

He asked me to rebuild the circuit inside the box
because this part is no longer supplied by the
manufacturer. But to me, it is too difficult because the box is filled with epoxy and could not be opened without being damaged. Adding to the difficulty is the fact that I didn't see the machine (it is 500km away in the mine). So I do not know how it works.

Does anyone in the list know the internal circuit of this box or know where they still have stock of it.

Thank you very much.
David Brown.
