Check the Bypass Drive 85T Timing
Belt. The belt is securely in place,
and is in good condition.
Y N
Replace the Bypass Drive 85T
Timing Belt (PL1.3A).
Check all Bypass Shafts, Rollers and
Idlers for proper operation. If any of
these components is faulty, replace it.
(PL5.2 A-C).
Carefully check the Bypass assembly in
the problem Stacker for other obstructions
and clear them. Check all Bypass Shafts,
Rollers and Idlers for proper operation. If
any of these components is faulty, replace
it.
(PL5.2 A-C).
13. Sequentially activate and deactivate the
Stacker Bypass Motor output. Observe
LED L0B2 at P/J 22 on the Stacker I/O
PWB in the problem Stacker.
LED L0B2 illuminates when the output is
active.
Y N
Go to Step 14.
Go to Step 16.
14. On the Stacker I/O PWB in the problem
Stacker, disconnect P/J 30. In the
Diagnostics Mode, activate the Bypass
Motor output. While the output is active,
observe L0B2 at P/J 22 on the Stacker I/O
PWB.
NOTE: In this step, you are checking
to see if the LED remains LIT when the
P/J is disconnected, NOT flashing.
LED L0B2 remains lit when P/J30 is
disconnected.
Y N
Reconnect P/J 30 and go to Step 15.
Go to Step 18.
15. Check the continuity of the harness
between the Punch Daughter PWB P22-2
and Stacker I/O PWB P22-OUTB2 in the
problem Stacker.
The continuity is OK.
Y N
Replace the harness between the
Punch Daughter PWB P22 and Stacker
I/O PWB P22 (PL 6.1D).
Replace the Little Star Controller
Expansion PWB (PL 3.1) for the problem
Stacker.
16. On the Stacker I/O PWB in the problem
Stacker, disconnect P/J 30. In the
Diagnostics Mode, repeatedly activate and
deactivate the Stacker Bypass Motor
output. Observe L0B2 on the Stacker I/O
PWB.
LED L0B2 lights when the output is
activated.
Y N
Reconnect P/J 30 and go to Step 17.
Reconnect P/J 30 and go to Step 18.
17. Check the continuity of the harness
between the Punch Daughter PWB P22-2
and Stacker I/O PWB P22-OUTB2 in the
problem Stacker.
The continuity is OK.
Y N
Replace the harness between the
Punch Daughter PWB P22 and
Stacker I/O PWB P22 (PL 6.1D).
Replace the Little Star Controller
Expansion PWB (PL 3.1).
18. The Bypass Motor is enabled by a ground
on P30-OUTB2. When the output is
activated, there should be 0VDC at this
point. When the output is deactivated,
there should be +24 VDC.
In the Diagnostics Mode, activate the
Stacker Bypass Motor output. While the
output is active, on the Stacker I/O PWB,
check for +24 VDC between P/J30-OUTB2,
and P/J 28-0VDC.
There is 0VDC when the output is activated
and +24 VDC with the output deactivated.
Y N
Replace the Stacker I/O PWB (PL
3.2.) in the problem Stacker.
Go to Step 19.
19. Disconnect P/J 10 on the Stacker AC/DC
Distribution PWB in the problem Stacker. In
the Diagnostics Mode, activate the Bypass
Motor output. With the output active, check
for 110 VAC across P/J 10-NUI and P/J 10-
RMTR.
There is 110VAC at this point.
Y N
Check the Top Cover Interlock by
disconnecting P/J 16B on the Stacker
AC/DC Distribution PWB and placing
a jumper across J16B-24V and J16B-
24VR. Activate the Bypass Motor
output and check for 110 VAC across
P/J 10-NUI and P/J 10-RMTR.
There is 110 VAC at this point when
the output is active.
Y N
Go to Step 20.
Go to RAP 3.2 Stacker Interlock
Switches to troubleshoot a problem
with the Stacker Top Cover Interlock.
