I have a Maho MH700C 432-9 (SW 311), and i was got an error M02 about 10-15sec after i start the hydraulic?
I was run the diagnostic test and the result was:
"Running test: 5= proc mod V24
Vart NR = 1 33800
Module Defective
Detected Error - Number is = 013"
So i was replace the memory card & CPU card, and ewerything looked fine and the same result!
And when i was look under the flatpanel, i was found that one ic was only fitted with one side of the ic pins(7pins of 14) in the socket. I was notice that one of the pins just touch the socket, but i was sure that i had found the the problem. So i replaced the ic in the socket(14pins of 14), but the problem was still there.
Then i was take out the 7 pins again, and now i was sure that the 7:th pin not were touching the socket, and now the machine run again without the M02 errorcode?
So now i wonder what the ic:s function are? The machine seems to work well without it? And when i run the diagnostic test, i still got the same errors? But the machine runs like it always did?
The ic i placed at the upper left corner, and marked with: CD 4093 BE RCA H 340
