    Dear all,

    I must say at start, this forum helped us a lot over the years to deal with various problems on our machines. Thank you!

    We currently have a problem with our polar cutting machine:
    -The CP battery went dead and therefore we got error (240). Until then the machine worked well.
    -The CP battery was replaced with a new one, and both memory banks has been erased and then error (240) stopped showing up and the machine stores its settings again when powered off.
    -When trying to do reference run, when trying to bring the limiter forward/backward it won't move and the attached error screen shows up.
    "POSITION COUNTER CHIP DEFECT (655)"
    In manual mode the machine works fine.

    Any ideas where to look?

    Best regards,
    Hadar

    Hi sir:

    Normally when this happen, you must replace the CPU board.

    However Reset the CPU board, and see if work, if does NOT work, please clean with electronic clean contact, the Edge Connector, and all EPROM, RAM, CPU, pins from all ICs. very well, with Carefully.

    See if work, otherwise, you must replace the CPU, but test the Clock if o.k in MHZ, and the power supply for the CPU Vcc pins, if are in tolerance by 0.7%!

    Hi, I have an update:

    Inspected and cleaned the CP board thoroughly, cleaned all front and backplane connectors.
    Reseated all chips on sockets on the board during cleaning.

    After turning on the machine checked all voltages to be in tolerance of 0.7% as suggested, and it is all good.

    Now the error gone and Backgauge calibration works flawlessly!

    Then light barrier was a bit off (Vibrations caused it to show "interrupted") message...
    I saw that the left side (the receiver) was very delicate if touched by hand, so opened its cover and saw that the board wasn't in place like it should, so opened the small screws and adjusted it.

    Now even when touching the receiver it won't get interrupted anymore.

    So the cutter fully works again!

    Thank you for pointing me to the CP board.

    Best regards
