3.17 POWER INDICATOR TROUBLESHOOTING GUIDE
NOTE
Before replacing any circuit boards, ensure applicable cables and connections are intact (visually and me-
chanically). To check for +5 VDC at various points called out in the troubleshooting, use digital ground as
a reference point (negative side of C18 on CPU litter board). When measuring 110 VAC at any point, use
only the neutral (white) side of the power line as a reference point. DO NOT use digital ground as a reference
point when measuring 110 VAC.
PROBLEM/SYMPTOM
SOLUTION(S)
Power indicator light does not light when bed pow-
er cord is plugged into the wall socket.
A. If all other functions on the bed are operating
correctly, check foot board keyboard (p/n 3000–
500–943). If all other functions on foot board key-
board operate properly, replace keyboard (see
page 202 for board location). If other functions are
not operating properly, check for +5 VDC at con-
nector P1, pin 6. If voltage is present and LED 6
does not light, replace keyboard.
B. If voltage is not present, check foot board IFC
(p/n 3000–500–955) for +5 VDC at connector P1,
pin 3 (see page 202 for board location). If voltage
is not present, check for +8 VDC at connector P3,
pin 5. If voltage is present and problem still exists,
replace foot board IFC.
C. If +8 VDC is not present, check litter CPU
board (p/n 3000–300–941) at connector P9, pin 5
for +8 VDC. If voltage is not present, check fuse
F1. If fuse is O.K., check connector P1, pin 10 for
110 VAC. If voltage is not present, replace litter
CPU board (see page 115).
D. If 110 VAC is not present, check power junction
board (p/n 3000–300–961) at connector P1, pin 1
(see page 199 for board location). If voltage is not
present, check fuse F1. If fuse is O.K., check for
110 VAC at connector J1, pin 2 (hot). Replace
fuse and/or power junction board, if necessary.
