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 the Fast-on connectors on the machine power inlet socket. Place the tester probes
across the live and neutral pins on the same connector. The measured voltage should be
approximately 220Vac/110Vac.
(2) Check if LED 1 and 2 (+5Vdc and +12Vdc), on the ARM board are on.
(3) Check if LED H6 and H3 +5Vdc and +12Vdc ( ALE driver ), or LED H2 and H3 ( AT UL
driver ), are on.
(4) Check if on connector J1, there is approximately 220Vac/110Vac, between pin 1 and 2 of the
driver box
(5) Check the continuity of the power supply signals on the CU242 cables between pin 1 and 5
(AT-UL driver) or on the CU243 cables between pin 1 and 5 (ALE driver) , by referring to
paragraph: 2.10. Cables” and replace what’s defective.
(6) Check if at the output to the Autotransformer there are the 220Vac, on the J1 connector.
(7) Check if the main voltage 220Vac/110Vac is present and the continuity of the on the CU145
cable, pins 1 and 2 .
