6. Check the continuity of the harness
between the Punch Daughter PWB P/J 22
and Stacker I/O PWB P22-OUTB5 in the
problem Stacker.
The continuity is OK.
Y N
Replace the harness between the
Punch Daughter PWB P/J 22 and
Stacker I/O PWB P22 (PL 6.2A).
Replace the Punch Daughter PWB (PL
3.1) associated with the problem Stacker.
If the problem is still present, replace the
Little Star Controller PWB (PL 3.1).
7. On the Stacker I/O PWB in the problem
Stacker, disconnect P/J 6B and Optical
Relay Opto4. In the Diagnostics Mode,
sequentially activate and deactivate the
Stacker Gate output. Observe L0B5 at P/J
22 on the Stacker I/O PWB.
LED L0B5 sequentially lights and
extinguishes when the output is toggled.
Y N
Reconnect P/J 6B, reinstall the
Optical Relay, and go to Step 8.
Reconnect P/J 6B, reinstall the Optical
Relay, and go to Step 9.
8. Check the continuity of the harness
between the Punch Daughter PWB P/J 22
and Stacker I/O PWB P22-OUTB5 in the
problem Stacker.
The continuity is OK.
Y N
Replace the harness between the
Punch Daughter PWB P/J 22 and
Stacker I/O PWB P22 (PL 6.2A).
Replace the Punch Daughter PWB (PL
3.1) associated with the problem Stacker.
If the problem is still present, replace the
Little Star Controller PWB (PL 3.1).
9. With the Stacker Gate output active, check
Optical Relay Opto4 on the Stacker I/O
PWB in the problem Stacker.
The light on the relay is lit when the output
is active.
Y N
Replace Optical Relay Opto4 on the
Stacker I/O PWB (PL 3.3).
Go to Step 10.
10. Check the 3-60 VDC, 3 amp fuse on the
Optical Relay.
The fuse is OK
Y N
Replace the fuse (PL 3.2).
Go to Step 11.
11. With the output active, check for +24VDC
supplied to the Stacker Gate Solenoid in
the problem Stacker, by placing the meter
leads across P/J 6B-24VP and P/J 6B-
OUTB5.
There is +24VDC across these points.
Y N
Replace the Stacker I/O PWB
(PL3.3).
In the problem Stacker check continuity
and for shorts to ground in the harness
between the P/J 6B on the Stacker I/O
PWB and the Stacker Gate Solenoid.
The harness is open or shorted to ground.
Y N
Replace the Stacker Gate Solenoid
(PL 5.2A).
Replace the harness (PL 6.2A).
12. Depending upon where the jam is
occurring, refer to the table for Stacker 1 or
Stacker 2 below. Enter the Diagnostic
Mode (GP1) and select the Stacker Bypass
Motor output:
Stacker 1:
Stacker 2:
Observe the operation of the Bypass
Assembly Belt in the problem Stacker. It
should be in position and running smoothly
when the output is active.
The Bypass Assembly Belt runs smoothly
when the output is active.
Y N
With the output active, check to see if
the Bypass Motor is running.
The Bypass motor is running when
the output is active.
Y N
Go to Step 13.
Check the Bypass Assembly Belt.
The belt is securely in place, and is in
good condition.
Y N
Replace the Bypass Assembly
Belt (PL5.2C).
