RAP
This RAP
is
used to locate and repair ground
faults in the primary AC power distribution
clrcultry.
You
were
directed
to
thls
RAP
from
another AC power RAP that traced the loss
of
AC
power to the
GFP
device.
The 2515 copier
is
equipped with an inline
Ground Fault Protection, (GFP) device
(Located on the power cord) that detects
excessive current leakage to ground. If
excessive leakage
is
detected the
GFP
device
will remove all power to the copier.
Initial Actions
Check that the correct voltage
is
being
applied to the copier at the wall
outlet.
Procedure
WARNING
I
Do not disconnect any
plugs
or
wires
while
the power cord is plugged Into the
wall and
the main power switch
is
on.
The Ground Fault Protector
is
in the tripped
Position (red flag
is
not
up).
N
Go to FLAG
1
and check that the correct
voltage
is
present. The voltage
is
correct.
Replace the Power OnlOff Switch (PL
1.1).
Go to the
1.1
AC Power RAP.
A
Refer to FLAG land disconnect
ACH
and ACN
at
Pins
2
and
5
of the Power OnlOff Switch.
Plug in the power cord and
test
the
GFP
according to the Warning
Icrhel,
The
GFP
passes the test.

Reconnect ACH and ACN wires to the Power
OnlOff Switch. Go to FLAG
2
and check that
the correct voltage
is
present. The voltage
is
correct.

Power RAP.
Go
to
FLAG
3
and disconnect the wires to the
Line Filter at the Line Filter. The
GFP
trips
(red flag
is
not up) after the Power OnlOff
Switch
is
turned on.

Reconnect the wlres to the Line Fllter.
Set the
DMM
to the
ZOK
resistance scale.
Switch off the Power OnIOff Switch and
unplug the power cord.
Go to the
F1
Fuser RAP and check for a
high resistance path from
ACH
or
ACN
to Ground. Look for pinched wires or
wires with frayed insulation. The
GFP
trips (red flag
is
not
up)
after the Power
OnIOff Switch
is
turned on.
