D-110 2K Lcss Power Distribution Rap - Xerox WorkCentre 5687 Series Service Manual

11D-110 2K LCSS Power Distribution RAP

The 2K LCSS has an integral power supply providing +24V and +5V supplies to the 2K LCSS
PWB. The AC power for the 2K LCSS power supply comes from the LVPS and base module of
the machine.
WARNING
Take care not to topple the LCSS.
The LCSS is unstable when un-docked from the machine.
Do not show the customer how to un-dock the LCSS.
CAUTION
Do not connect the finisher power cord directly to the AC wall outlet. The finisher cannot oper-
ate without the machine. The machine controls the distribution of electricity to the finisher for
correct power on and power off sequencing.
Procedure
WARNING
Take care when measuring AC mains (line) voltage. Electricity can cause death or injury.
Close or cheat all the 2K LCSS interlocks. LED 2 on the 2K LCSS PWB is illuminated.
Y N
+24V is available at Fuse (F1) on the 2K LCSS PWB.
Y N
Go to Flag 2. +24V is available at P/J300 between pins 1 and 2, also between
pins 5 and 3.
Y N
Disconnect P/J300. +24V is available at P/J300 between pins 1 and 2, also
between pins 5 and 3 on the end of the harness.
Y N
Figure 1. Loosen the 4 screws and lift the power supply module away from
the 2K LCSS frame. Go to Flag 1. ACL is available at CN1 between
pins 1 and 3.
Y N
Go to the 01C AC Power RAP and check the AC output voltages.
Check the wiring between CN2 and P/J300. The wiring is good.
Y N
Repair the wiring.
Install a new power supply module, PL 11.26 Item 2.
Check for a short circuit or an overload in the wiring or components connected
to the +24V on the 2K LCSS PWB. Refer to GP 7.
+24 V is available at PJ315 pin 5 on the 2K LCSS PWB.

Do not install a fuse of a different type or rating. Installing the wrong type or
rating of fuse can cause overheating and a risk of fire.
Perform the following:
• Switch off the machine, GP 14.
• Go to Flag 3, disconnect all the +24V harnesses to components.
• Check each harness for short circuits and overheating, GP 7.
• Repair or install new components as necessary.
• Install a new fuse F1 on the 2K LCSS PWB, switch on the machine, GP 14.
• Monitor the voltage at the left end of the fuse and re-connect the circuits one at
a time. Energize the re-connected components using dC330 control codes.
• If the voltage drops below +22V, switch off the machine, GP 14. Re-check the
component and harness for overheating or short circuits. Repair or install new
components as necessary.
Perform the 11G-110 2K LCSS PWB Damage RAP, if necessary install a new 2K LCSS
PWB, PL 11.26 Item 1.
Go to Flag 2. +5V is available at P/J300 between pins 4 and 6, also between pins 7 and 8.
Y N
