STBY +5VDC Power RAP
BSD-ON:
BSD 1.2 - Main Power on (2 of 2)
BSD-ON:
BSD 1.4 - DC Power Generation (1 of 2)
NOTE: When turning the power OFF; first, turn OFF the Power Switch, then the Main Power
Switch.
Procedure
Turn the Main Power Switch ON, then turn the Power Switch ON. +5VDC is measured at the
Main LVPS between
P/J501
pins 7, 8, 9, and 10 (+); and GND (-) (
BSD 1.4 - DC Power
Generation (1 of 2)
).

AC line voltage is measured at the Main LVPS between
P/J1
pin 1 and pin 3 (
BSD
1.2 - Main Power on (2 of 2)
).
Y

Go to
AC Power RAP
.
Turn the power OFF and disconnect
P/J501
on the Main LVPS. Turn ON machine power,
wait 15seconds. +5VDC is measured at the Main LVPS between
P/J501
pins 7, 8, 9,
and 10 (+); and GND (-).

Replace the Main LVPS (
PL 18.2
).
Check the +5VDC circuit for a short circuit to frame by referring to Chapter 7 Wiring Data.
Check the wire to the applicable component for an open circuit or poor contact by referring to
Chapter 7 Wiring Data.

BSD 1.4 - DC Power Generation (1 of 2)
BSD-ON:
BSD 1.7 - DC Power Distribution (options)
BSD-ON:
BSD 1.9 - Power Interlock Switching (2 of 2)
NOTE: When turning the power OFF; first, turn OFF the Power Switch, then the Main Power
Switch.
When measuring the voltage (+5VDC), turn ON the power then measure it before the machine
goes into the Power Save mode.
Procedure
Turn the power ON; turn ON the Main Power Switch, then turn ON the Power Switch.
+5VDC is measured at the Main LVPS between
P/J501
pin 3 and pin 5 (+), and GND (-)
(
BSD 1.7 - DC Power Distribution (options)

Turn the power OFF and disconnect the Main LVPS connectors
P/J502
,
P/J503
, and
P/
J506
. Turn ON machine power, wait 15 seconds. +5VDC is measured at the Main LVPS
between

•
Ensure that
P/J501
on the Main LVPS and
P/J300
on the ESS PWB are
properly seated and that the Wire Harness is not damaged (
BSD 1.4 - DC
Power Generation (1 of 2)
).
•
If the checks are OK, go to
STBY +5VDC Power RAP
.
The +24VDC LED, Orange, on the ESS PWB is lit (
Figure 1
).

Check in the following order:
•
Ensure that
P/J501
on the Main LVPS and
P/J300
on the ESS PWB are
properly seated, and that the Wire Harness is not damaged (
BSD 1.4 - DC
Power Generation (1 of 2)
).
•
Refer to
(BSD 1.3 - LVPS Control
) and check the 5V C-F On Signal to the
Main LVPS.
•
Replace the Main LVPS (
PL 18.2
).
