Possible cause check-up and tests
— It is possible that the dual power
supplies outputs 12V, but the 5V
circuit is faulty. To identify the faulty
item proceed as follows:
— Check the connection between the two
electronic boards ANL-T2 and DIG-
T2.
— Check the cable, which transfers the
voltage from the AC-T1/JP2
connector to the power supply.
— Check the input voltage of the electric
box, at the AC-INPUT connector, on
the AC-T1 board/JP3.
— Check if there is no short-circuit at the
AC-OUTPUT connector on the AC-
T1 board (JP2).
— Check if there is no short-circuit at the
input connector (JP3) or at the output
connector (JP5) on the ANL-T2 board.
1.6 Check the DC voltages supply to the system.
Check main power switch.
1.6.1 Check the grounding
— Plug connector 26 pin FLAT of the
test board into connector JP5 mounted
on board ANL-T2.
— Connect the negative probe of the
multitester to TP1 on the test board.
