+5VDC Power RAP, +24VDC Power RAP
Status Indicator RAPs
Initial Issue
Check the +5VDC circuit for a short circuit to frame by referring to Chapter 7 Wiring Data.
Measure for +5VDC on the Main LVPS at the following locations:
•
Between
P/J503
pin 7 (+) and GND (-) (
BSD 1.4 - DC Power Generation (1 of 2)
).
•
Between
P/J506
pin 1 (+) and GND (-) (
BSD 1.9 - Power Interlock Switching (2 of 2)
).
+5VDC is measured at both locations.
Y
N
Replace the Main LVPS (
PL 18.2
).
Check the wire to the applicable component for an open circuit or poor contact by referring to
Chapter 7 Wiring Data.

NOTE: When turning the power OFF; first, turn OFF the Power Switch, then the Main Power
Switch.
Procedure
Turn the power ON; turn ON the Main Power Switch, then turn ON the Power Switch.
+24VDC is measured at the Main LVPS between
P/J501
pin 6 (+), and GND (-) (
BSD 1.5 -
DC Power Generation (2 of 2)
).
Y
N
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
N
Go to
AC Power RAP
.
Turn the power OFF and disconnect the Main LVPS connectors
P/J501
,
P/J502
, and
P/
J503
. Turn ON machine power, wait 15 seconds. +24VDC is measured at the Main
LVPS between
P/J501
pin 6 (+), and GND (-)
(BSD 1.5 - DC Power Generation (2 of
2)
).
Y
N
+5VDC is measured at the Main LVPS between
P/J502
pins 3 and pin 5 (+), and
GND (-)
(BSD 1.5 - DC Power Generation (2 of 2))
.
Y
N
+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)
).
Y
N
Go to
STBY +5VDC Power RAP
.
Refer to
BSD 1.3 - LVPS Control
and check the 5V C-F On Signal to the Main
LVPS.
If the problem continues, replace the Main LVPS (
PL 18.2
).
Replace the Main LVPS (
PL 18.2
).
Check the +24VDC circuit for a short circuit to frame by referring to Chapter 7 Wiring
Data.
