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 (-)
Generation (1 of 2)).
Y N
AC line voltage is measured at the Main LVPS between
1.2 - Main Power on (2 of 2)).
Y N
Go to AC Power RAP.
Turn the power OFF and disconnect
wait 15seconds. +5VDC is measured at the Main LVPS between
and 10 (+); and GND (-).
Y N
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.
