YN
+5 VDC is measured between P
/J
418B-5 and GND on the IOT Drive PWB.
YN
+5 VDC is measured between P/
J418B-6
and P/J418B-4 on the IOT Drive
PWB.
YN
Go to the +5 VDC (IOT) Wirenet and check the wires between P/
J21 -1
on t
he IOT LVPS and P/J418B8-6 on the IOT Drive PWB. Go to the DC
COM (IOT) Wirenet and check the wires between P/J21-5 on the IOT
LVPS and P/J418B-4 on the IOT Drive PWB.
Go to Fl
ag 1 on BSD
9.11 and check the wire for a short circuit to ground. Go to
Flag 3 on BSD 9.11. Check the wires for an open circuit. If the wires are good,
replace the IBT Clean Blade Home Position Sensor (PL 7.3).
Replace the IOT Drive PWB (PL 9.2).
Enter dC330 009-059 2ND Belt Transfer Roll Retract. Press Start
. Enter dC330 009-067
IBT Cleaner Retract. Press Start. The Cleaner Retract Clutch energizes.
YN
+24 VDC is measured between P/
J417A-9
and P/J417A-10 on the IOT Drive
PWB.
YN
+24 VDC is measured between P/
J417A-9
and GND on the IOT Drive
PWB.
YN
Go to the +24 VDC-4 Wirenet and check the wires between P/
J24-2 on
the I
OT LVPS and P/J417A-9 on the IOT Drive PWB.
Go to Flag 2 on BS
D 9.11. Check the wires for an open circuit or a short circuit.
If the wires are good, replace the IOT Drive PWB (PL 9.2). If the problem con-
tinues, replace the Cleaner Retract Clutch (PL
1.
3).
Go to Flag 2 on BSD 9.11 and check the wires for an open circuit. If the wires are
good, replac
e the Cleaner Retract Clutch (PL 1.3).
Check the Cleaner Retract Clutch for binding or intermittent operation. If the Cleaner
Retract
Clutch is good, replace the IBT Clean Blade Home Position Sensor (PL 7.3). If the
problem continues, replace the Cleaner Retract Clutch (PL 1.3).
Replace the IOT Drive PWB (PL 9.2).
