Rap 5.5 Stacker Bypass Exit Sensors - GBC FusionPunch II Service Manual

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 S2 INB8 BypassSensor
Bypass Exit I16 1100110011001100
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.

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).

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.

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.
