Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
To speed up the troubleshooting procedure, check the state of the power indicator LEDs
on the various circuit boards.
(1) Slightly lift up the Faston connectors on the machine power inlet socket. Place the tester
probes across the live and neutral pins on the same connector. The measured value should be
approximately 220 VAC or 110 VAC depending on the mains voltage.
(2) As for step (1) but across pins 3 and 1 of connector CN3 on the brake board.
(3) Using a tester, check that all the output voltages on connector CN1 of the brake board are
correct, referring to paragraph 2.8. “Cables”.
(4) With cable CB-51 connected, place the tester probes across pins 1 and 2 of connector CN2 of
the brake board. The measured value of resistance should be different from 0.
(5) Disconnect cable CB-51 from the winding and place the tester probes across the terminals of
the winding. The measured value of resistance should be different from 0.
(6) Using a tester, check that cable CB-51 is correct, referring to paragraph 2.8. “Cables”.
(7) As for step (3) but on connector CN7 of the CPU board.
