Status Indicator RAPs
OF4-002 Drum 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 5 on BSD 4.1 and check for +5 VDC at P/J42-4 on the Distribution PWB. +5 VDC
is measured at P/J42-4 on the Distribution PWB.
YN
Perform the following:
•Go to Fl
ag
5 on BSD 4.1 and check for a short/open circuit.
• Go to the +5
VDC Power (IOT LVPS) RAP.
Perform the following:
• Enter DC330 004-021 Drum Motor. Press Start and Sto
p.
• Check for a change of state from (L) to +5 VDC at P/J41
7B-18 on the IOT Drive PWB.
The voltage at P/J417B-18 sw
itched between (L) and +5 VDC on the IOT Drive PWB.
YN
Perform the following:
•Go to Fl
ag
7 on BSD 4.1 and check for an open/short circuit.
• Replace the Drum Motor (PL 1.
1).
• Replace the IOT Drive PWB (PL 9.2).
Go
to Flag 6 on
BSD 4.1 and check for +24 VDC at P/J42-2 on the Distribution PWB. +24
VDC is measured at P/J42-2 on the Distribution PWB.
YN
Perform the following:
•Go to Fl
ag
6 on BSD 4.1 and check for a short/open circuit.
• Go to the +24
VDC Power (IOT LVPS) RAP.
Enter DC330 004-021 Drum Motor. The Drum Motor runs.
YN
Check for Logic (L) at P/
J417B-18 Logic
(L) is measured at P/J417B-18
YN
Perform the following:
•Go to F
lag 8 on BSD
4.1 and check for an open/short circuit.
• Replace the Drum Motor (PL 1.
1).
• Replace the IOT Drive PWB (PL 9.2).
P
erform the following:
• While exercising DC330 004-021 Drum Motor, check for a change of state on the
Drum Mot
or On line P/J417B.
• While in [04-021] Component Control and the Drum Motor is running, check for the
following conditi
ons at
