3.6 HEAD SECTION (FOWLER) RAISE/LOWER TROUBLESHOOTING GUIDE
(CONTINUED)
PROBLEM/SYMPTOM
SOLUTION(S)
Head section does not raise electrically.
Head section does not lower electrically.
(continued)
E. Check Fowler up/down motor for operation. If
motor is not operating, check for 110 VAC supply
to motor. If 110 VAC is present and motor does
not turn, replace motor (p/n 3000–300–472) (see
page 103 & 104). Check Fowler up/down motor
capacitor. Replace, if necessary (see pages 103
& 104).
F. Check for +5 VDC at pendant port cable (p/n
3000–915–839), pin 11. If voltage is not present,
check pin 11 of connector P5 on the headwall IFC
board. Replace headwall IFC board and/or
cables, if necessary (see pages 199 & 211 for
board and cable locations).
G. Check headwall IFC board for +5 VDC (con-
nector P5, pin 11) output to pendant switches.
Replace headwall IFC board and/or cables, if nec-
essary (see pages 199 & 211 for locations).
H. Replace any one of the following boards, if nec-
essary. Verify interconnecting cables and connec-
tions prior to board replacement.
1.) Foot board IFC board (p/n 3000–500–955)
2.) Litter CPU board (p/n 3000–300–941)
3.) Signal junction board (p/n 3000–300–963)
4.) Headwall IFC board (p/n 3000–303–933) (see
page 199 & 202 for board locations).
I. If motor is operating and Fowler does not move
or moves incorrectly, check the following mechani-
cal items:
1.) Fowler nut damaged. Screw shaft turns but
head section does not move: Check snap ring and
ensure proper fit (see pages 107 & 108).
2.) Motor coupling not turning with motor shaft.
Check coupling for proper operation.
3.) Screw shaft turns but head section doesn’t
move: check CPR cable release and adjustments
(see page 109 & 110).
4.) Check screw shaft guide (white).
5.) Check motor mounting and blue bushings.
Worn bushings may cause excessive noise and
vibration.
6.) Check main pin connecting head litter section
with bracket.
