01G +17V Distribution RAP
Use this RAP to diagnose +17V supply and distribution faults.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to GP 14. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Check the power distribution PWB. Follow the distribution back to the supply. Repair the wiring,
REP 1.1 or install a new PWB or power supply unit, PL 1.15 Item 2 as necessary.
NOTE: To view the +17V supply generation, refer to WD 1.5.
NOTE: The voltage of this supply varies. At start up, the output is +17V unregulated and an
average of about +17V can be measured. During the normal run mode, the output of this sup
-
ply rises to +24V. The supply then drops back to +17V unregulated during the sleep mode. If
the yellow LED is lit on the power supply, the output should be about +24V.
Power distribution PWB
• To view the +17V distribution from the power supply unit, refer to WD 1.5.
NOTE: A short circuit on this output also disables the +3.3V ESTAR output.
NOTE: A short circuit on the +3.3V may result in the +17V output being disabled from
overload.
NOTE: A missing or invalid power normal signal (refer to WD 8.2 on PJ402 pin 10) may
result in an overload on the +17V output, causing the supply to be disabled.
• For +17V faults on the power distribution PWB, refer to:
– WD 1.5
– WD 1.6
• If necessary, install a new power distribution PWB, PL 3.11 Item 1.
