10. In the Diagnostics Mode, sequentially turn
on the outputs for each Offset Solenoid.
Using the information in the following table,
on the Stacker I/O PWB, check for
+24VDC supplied to each offset solenoid.
There is +24VDC across these points.
Y N
Replace the Stacker I/O PWB
(PL3.2).
Check continuity and shorts to ground
between the Stacker I/O PWB and each
offset solenoid.
The harness is open or shorted to ground.
Y N
Replace the defective Offset
Solenoid (PL 5.1C).
Replace the harness (PL 6.2A).
11. In the Diagnostics Mode, sequentially
activate and deactivate the O-Ring Motor
output. Observe LED L0A8 on the
Stacker I/O PWB.
LED L0A8 illuminates when the output is
active.
Y N
Go to Step 12.
Go to Step 14.
12. On the Stacker I/O PWB, disconnect P/J
30. In the Diagnostics Mode, activate the
Stacker O-Ring Motor output. While the
output is active, observe L0A8 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 L0A8 remains lit when P/J30 is
disconnected.
Y N
Reconnect P/J 30 and go to Step 13.
Go to Step 16.
13. Check the continuity of the harness
between the Punch Daughter PWB P23-8
and Stacker I/O PWB P23A-OUTA8.
The continuity is OK.
Y N
Replace the harness between the
Punch Daughter PWB P23 and
Stacker I/O PWB P23 (PL 6.1D).
Replace the Little Star Controller
Expansion PWB (PL 3.1).
14. On the Stacker I/O PWB, disconnect P/J
30. In the Diagnostics Mode, repeatedly
activate and deactivate the Stacker O-
Ring Motor output. Observe L0A8 on the
Stacker I/O PWB.
LED L0A8 lights when the output is
activated.
Y N
Reconnect P/J 30 and go to Step 15.
Reconnect P/J 30 and go to Step 16.
15. Check the continuity of the harness
between the Punch Daughter PWB P23-
8 and Stacker I/O PWB P23A-OUTA8.
The continuity is OK.
Y N
Replace the harness between the
Punch Daughter PWB P23 and
Stacker I/O PWB P23 (PL 6.1D).
Replace the Little Star Controller
Expansion PWB (PL 3.1).
16. The O-Ring Motor is enabled by a
ground on P30-A8. When the output is
deactivated, there should be +24 VDC at
this point. When the output is active,
there should be 0 VDC.
In the Diagnostics Mode, deactivate the
O-Ring Motor output. While the output is
deactivated, on the Stacker I/O PWB,
check for +24 VDC between P/J30-
OUTA8, and P/J 12-0VDC. Then,
activate the output and check for 0 VDC
at the same location.
There is +24 VDC with the output
deactivated and 0 VDC when it is
activated.
Y N
Replace the Stacker I/O PWB (PL
3.2).
Activate and deactivate the O-Ring
Motor output. While the output is active,
on the Stacker AC/DC Distribution PWB,
check for 0 VDC and +24VDC between
P/J11-MT2, and P/J 12-0VDC.
