Refer to
Figure 5
and the
Component list
to isolate and repair the compo-
nent that is causing the short.
Disconnect
P/J17
,
Flag 15
and
P/J16
,
Flag 11
. Less than 100 Ohms resis-
tance is measured on the harness between P27 pin 1 and the machine
frame, also between P27 pin 2 and the machine frame.

Refer to
Figure 4
and the
Component list
to isolate and repair the compo-
nent that is causing the short.
Install a new LVPS and base module,
PL 1.10 Item 3
.
Switch on the machine,
GP 14
. +10.9V or greater is available on
P/J17
pin 6 (yel-
low wire, bottom of connector).
Y
N
The +12V interlock voltage used to maintain the +24V interlocked circuit is not
available or below specification, go to the
01-300
Front Door Open RAP to fix
the fault.
Switch off the machine,
GP 14
. Pull out the single board controller PWB module,
PL
3.24 Item 1
. Disconnect
P/J131
,
Flag 1
. Switch on the machine,
GP 14
. +24V is
available on the harness between P131 pin 1 to the machine frame and P131
pin 2 to the machine frame.
Y
N
Install a new LVPS and base module,
PL 1.10 Item 3
.
Components in the single board controller PWB module, scanner or DADH are
shorting the +24V to ground, refer to
Flag 1
,
Flag 2
,
Flag 3
and
Flag 4
to isolate and
repair the short circuit.
The
fuse F1
on the IOT PWB is blown, therefor a new IOT PWB will need to be installed.
Before installing a new IOT PWB, find the cause of the failure, refer to
Figure 2
,
Figure 3
and the
Component list
. Refer also to the
01H
Short Circuit and Overload RAP. When the
cause of the high resistance short circuit has been repaired, install a new IOT PWB,
PL
1.10 Item 2
.
NOTE: CR16 will light at voltages of less than+24V.
The voltage at
P/J27
pin 1and pin 2 is equal to or greater than +24V
Y
N
Install a new LVPS and base module,
PL 1.10 Item 3
.
The voltage measured at the top cap of
fuse F1
is the same as the voltage measured on
the bottom cap of
fuse F1
.
Y
N
A high resistance short circuit has damaged the
fuse F1
. Identify and repair the cause of
the high resistance short circuit, refer to
Figure 2
,
Figure 3
and the
Component list
. Refer
also to the
01H
Short Circuit and Overload RAP. When the cause of the high resistance
short circuit has been repaired, install a new IOT PWB,
PL 1.10 Item 2
.
+24V interlocked is available to the IOT PWB, exercise the machine in all possible modes and
make a note of what components are energized when the fault occurs. Refer to the
Component
list
and the appropriate circuit diagram to isolate and repair the problem component or circuit.
Component list
Refer to
Figure 2
,
Figure 3
,
Figure 4
and
Figure 5
. Go to the appropriate component in the list
that follows that has a s24V supply. Inspect then re-seat all PJs and check the wiring,
