During power On process, NCU checks FAn connection & its operation. If the fans are not detected, it stops booting & displays 8 on NCU 7 segment. HTH.

The problem has already been eliminated by changing to another NCU, perform the change of the fan module and it did not work, so the other NCU had to be installed, what is not clear to me is why it presents this problem if the machine does not have more 2 years? I am concerned about not having the reliability of equipment of this brand. regards redss fgsdfg SINUMERIK 840D sl NCU720.3 NP stopped working. A few seconds after power on all leds turn orange.
