Rap 1.5 Stacker +24Vdc Power - GBC FusionPunch II Service Manual

RAP 1.5 Stacker +24VDC Power

Description
This RAP is used to troubleshoot problems with
+24VDC power to the Stacker. It can be used
for Stackers that are configured with or without
a Bypass.
For machines configured with a Bypass, this
RAP will also provide procedures to
troubleshoot +24VDC power to a second GBC
Stacker. This RAP does not contain
procedures for other downstream devices.
NOTE: For machines without a Bypass
installed, this procedure will still refer to
the single stacker as Stacker 1.
Initial Actions
Check fuse FS-1 on the Punch +24VDC Power
Supply PWB (PL 3.1). If this fuse is blown, the
machine may appear to have a problem with
main AC Power.
Procedure
1. Ensure all machine interlocks are closed.
Switch off Stacker Main Power and remove
the Stacker 1 Rear Panel.
2. The Stacker is equipped with a Bypass.
Y N
On the Stacker AC/DC Distribution
PWB, disconnect the 4 pin connector
that makes up P/J 6A and P/J16A.
Check continuity between:
• P 6A-24VI and P 6A-24V.
• P 16A-24VI and P 16A-24V.
There is continuity through the closed
Stacker Interlocks.

Go to RAP 3.2 Stacker Interlock
Switches.
Reconnect P/J 6A and P/J16A and go
to Step 4.
Go to Step 3.
3. On the Stacker 1 AC/DC Distribution PWB,
disconnect P/J 16B. Check continuity
between P 16B-24VI and P 16B-24V
(across the orange and yellow wires).
There is continuity through the closed
Stacker 1 Top Cover Interlock.
Y N
Reconnect P/J 16 and go to RAP 3.2
Stacker Interlock Switches.
Reconnect P/J 16 and go to Step 4.
4. Switch on the Main Power.
WARNING
There are areas of high voltage in the
Stacker. Use caution when working in
this area with the multimeter probes.
5. On the Stacker 1 AC/DC Distribution PWB,
check for +24 VDC between P/J 14-24V
and P/J 14-0V.
The voltage is +23.5 VDC to +25.5 VDC.
Y N
Remove the Punch Right Rear Panel
and on the Punch AC/DC Distribution
PWB, check for +24 VDC between P/
J 14-24V and P/J 14-0V.

2-13
The voltage is +23.5 VDC to +25.5
VDC.
Y N
Go to RAP 1.4 Punch +24VDC
Low Voltage Power Supply RAP.
Replace the harness between P/J 14
on the Punch AC/DC Distribution
PWB and P/J 14 on the Stacker AC/
DC Distribution PWB (PL 6.1B).
Go to Step 6.
6. On the Stacker 1 AC/DC Distribution PWB,
check for +24 VDC between P/J 12-24V
and P/J 12-0V.
The voltage is +23.5 VDC to +25.5 VDC.
Y N
Replace the Stacker 1 AC/DC
Distribution PWB (PL 3.2).
On the Stacker 1 I/O PWB, check for +24
VDC between P/J 28-24V and P/J 28-0V.
The voltage is +23.5 VDC to +25.5 VDC.
Y N
Replace the harness between P/J 28
on the Stacker 1 I/O PWB and P/J 12
on the Stacker 1 AC/DC Distribution
PWB (PL 6.2A).
The Stacker 1 +24 VDC Power Circuit are
OK. Go to Step 7 to check +24 VDC
Power for Stacker 2.
