Status Indicator RAPs
01J +50V Distribution RAP
Use this RAP to diagnose +50V 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.
To view the +50V generation, refer to WD 1.3.
Check the red LED on top of the power supply unit, Figure 1, that indicates that the +50V sup-
ply is available in the power supply unit. The red LED is lit and the AC supply is good.
YN
Install a new power supply unit, PL 1.15 Item 2.
Check the PEST fault history, dC123. There are hard PEST faults shown.
YN
Check that the +50V is within tolerance, +50V +/- 2% at JDC1 pin 10. Refer to WD 1.4.
The +50V is good.
YN
Install a new power supply unit, PL 1.15 Item 2.
Determine which PWB has the supply fault. Go to PWB Checks.
Perform the RAP(s) given by the hard PEST fault code(s), then return to this RAP.
PWB Checks
Check the PWB’s below to determine which PWB has the distribution fault. Follow the distribu-
tion 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. Refer to GP 15 for the location and function of the LED’s on the
PWB’s.
NOTE: Many PWB’s have distribution fuses.
