— If the DC voltages at the power supply
connector are incorrect or missing, with
the load disconnected, then replace the
power supply.
— Replace faulty cables.
— Fix damaged connectors
— If voltages are missing or incorrect then
replace the ANL-T2 board
Possible cause check-up and tests
— Check for AC power at the JP2
connector on the AC-T1 board
— Check for power at the AC input to the
power supply
1.4 Check the DC voltages supplied to the
system.
— Connect the Test Point board to the
JP7 connector on the ANL-T2 board.
— Connect the negative probe of a
multimeter to TP1 on the test board.
— With the positive probe check TP2 for
+5V DC, an acceptable range is
4.9 – 5.3V
— With the positive probe check TP3 for
+12V DC, an acceptable range is
10.8 – 12.5V
— If either voltage is incorrect or missing,
then remove the output connector from
the power supply and recheck at the
power supply connector.
— If the voltages are with in range then
reconnect the output connector and
proceed
— Turn off the power and disconnect all
connectors except JP8 from the
ANL-T2 board. Inspect all cables for
loose connectors and all connectors for
bent pins.
