RAP 5.5 Stacker Bypass Exit Sensors
Description
This RAP is used to troubleshoot problems with
the Stacker Bypass Exit Sensors for Stacker 1
and Stacker 2. Problems with these sensors
can result in jams, and declarations of faults in
other areas. This RAP is only used with
Stackers that have a Bypass installed.
Procedure
1. Refer to the table for Stacker 1 or Stacker 2
below. If two Stackers are installed, test
both. Enter the Diagnostic Mode (GP1)
and select the Bypass Exit Sensor input.
Stacker 1:.
Stacker 2:.
Sequentially block and unblock the sensor
and observe the Control Panel for a change
in state (0 to 1, or 1 to 0).
There is a change in state when the sensor
is blocked and unblocked.
Y N
Go to Step 2.
Go to Step 3.
2. Using the following table, on the Stacker
I/O PWB check the LED that corresponds
with the sensor. Sequentially block and
unblock the sensor and observe the LED
for a change in state (Blocked = Off,
Unblocked = On).
There is a change in the LED state when
the sensor is blocked and unblocked.
Y N
Go to Step 4.
Go to step 3.
3. In the problem Stacker, check the continuity
of the cable between the Stacker I/O P25-
INB8 and the Punch Daughter PWB P/J25-
8.
The continuity is OK.
Y N
In the problem Stacker, replace the
cable between the Stacker I/O PWB P/
J 25 and the Punch Daughter PWB P/J
25 (PL 6.2A).
Replace the Punch Daughter PWB
associated with the problem Stacker (PL
3.1). If the problem is still present, replace
the Little Star Controller (PL 3.1).
4. On the Stacker I/O PWB in the problem
Stacker, disconnect P/J 1. Check LED LIB8
to see if it is lit when the connector is
disconnected.
NOTE: In this step, you are checking
to see if the LED remains LIT when the
P/J is disconnected, NOT flashing.
LED LIB8 remains lit when P/J1 is
disconnected.
Y N
Leave the connector disconnected
and go to Step 5.
Leave the connector disconnected and go
to Step 6.
5. In the problem Stacker, check the continuity
of the cable between the Stacker I/O P25-
INB8 and the Punch Daughter PWB P/J25-
8
The continuity is OK.
Y N
In the problem Stacker, replace the
cable between the Stacker I/O PWB P/
J 25 and the Punch Daughter PWB P/J
25 (PL 6.2A).
Replace the Punch Daughter PWB
associated with the problem Stacker (PL
3.1). If the problem is still present, replace
the Little Star Controller (PL 3.1).
6. On the Stacker I/O PWB in the problem
Stacker, place a jumper between the P/J 1-
INB8 and P/J1-0V. With the jumper in
place, LED LIB8 should extinguish.
