1.5 Ground Fault (2515 W/Tag/Mod 5) Rap - Xerox 2510 Service Manual

1.5 Ground Fault (251 5 WI
TAG/ MOD
5) 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 A C power RAP that traced the loss
of
AC
power to the
GFP
device.
The 2515 copier i s 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 i s 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 t o 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 A C Power RAP.
A
Refer to FLAG land disconnect ACH and ACN
a t 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.

I
Replace the G F P (PL 1.2).
Reconnect ACH and ACN wires to the Power
OnlOff Switch. Go to FLAG 2 and check that
the correct voltage i s present. The voltage is
correct.

I
Go to the 1.1
AC
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.
Y N
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.
