Reissue
OF4-001 Main Motor RAP
This RAP is used to repair the Main Motor and Drum Motor circuit failures when directed by
another RAP.
Initial Actions
• Refer to BSD 4.1, Main and Drum Drive Control, in the following procedure:
• Check the Drive Mechanism for damage, jams, and obstructions.
Procedure
Go to Flag 1 BSD 4.1 and check for +5 VDC at P/J42-14 on the Distribution PWB. +5 VDC is
measured at P/J42-14 on the Distribution PWB.
YN
Perform the following:
•Go to Fl
ag
1 BSD 4.1 and check for a short/open circuit.
• Go to the +5
VDC Power (IOT LVPS) RAP.
Perform the following:
• Enter DC330 004-007 Main Motor, Press Start and S
top.
• Check for a change of state from (L) to +5 VDC at P/J41
7B-5 on the IOT Drive PWB.
The voltage at P/J417B-5 sw
itched between (L) and +5 VDC at P/J417B-5 on the IOT
Drive PWB.
YN
Perform the following:
•Go to Fl
ag
3 on BSD 4.1 and check for an open/short circuit.
• Replace the Main Motor (PL 1.2).
• Replace the IOT Drive PWB (PL 9.2).
Go
to Flag 2 on B
SD 4.1 and check for +24 VDC at P/J42-11 and 12, on the Distribution PWB.
+24 VDC is measured at P/J4
2 -11 and 12, on the Distribution PWB.
YN
Perform the following:
•Go to Fl
ag
2 on BSD 4.1 check for an open/short circuit.
• Go to the +24
VDC Power (IOT LVPS) RAP.
Enter DC330 004-007 Main Motor. Press Start. The Main Motor runs.
YN
Check for Logic (L) at P/
J417B-5. L
ogic (L) is measured at P/J417B-5.
YN
Perform the following:
•Go to on Fl
ag
4 BSD 4.1 and check for an open/short circuit.
• Replace the Main Motor (PL 1.2).
• Replace the IOT Drive PWB (PL 9.2).
P
erform the following:
• While exercising [04-021] in Component Control, check for a change of state on the
Main Motor O
n line P/J417B-5.
• While in [04-021] Component Control and the Main Motor is running, check for the
following conditi
ons at
– P/J417B-5,
Logic (L)
– P/J417B-4
, +2.5 VDC
– P/J417B-3,
Logic (L)
– P/J417B-2,
Logic (L)
•Go to Flag 4 on
BSD 4.1 and check for an open /short circuit.
• Replace the Main Motor (PL 1.2).
•
Replace the IOT Drive PWB (PL 9.
2).
Perform the following:
• While in [04-007] Component Control and the Main Motor is running, check for the follow-
ing conditions at
– P/J417B-5,
Logic (L)
– P/J417B-4
, +2.5 VDC
– P/J417B-3,
Logic (L)
– P/J417B-2,
Logic (L)
•Go to Flag 4 on
BSD 4.1 and check for an open /short circuit.
• Replace the Main Motor (PL 1.2).
•
Replace the IOT Drive PWB (PL 9.2).
