3.2 MOTION INTERRUPT TROUBLESHOOTING GUIDE
NOTE
Prior to replacing any circuit boards, ensure applicable cables and connections are intact (visually and me-
chanically). When measuring 110 VAC at any point, use only neutral (white) side of power line as a reference
point. DO NOT use digital ground as a reference point when measuring 110 VAC.
Visually and mechanically check for motion interrupt pan alignment and movement. Observe whether the
pan has been damaged. Any significant alteration in the shape of the pan may affect switch actuation. If the
pan’s shape is altered enough to affect the motion interrupt switches, replace the pan (p/n 3000–300–50) (see
page 95).
PROBLEM/SYMPTOM
SOLUTION(S)
Motion interrupt does not disable the movement of
the bed when activated. (Motion of bed may be
prevented if the switch is constantly activated by a
foreign object.)
A. Check individual motion interrupt switches for
actuation and plunger travel. If switches appear to
be dismounted and/or damaged, replace as nec-
essary (see page 96).
B. Using a voltmeter, check for +12 VDC at each
switch. Wire colors represent: red, +12 VDC,
black, ground reference. Replace switches as
necessary.
C. If +12 VDC is present at switches, verify the 2
pin plug from the motor stop cable is plugged into
P2 of the power junction board (p/n 3000–300–
961) (see page 199 for board location).
D. If +12 VDC is not present at the switches,
check connector P14, pin 5 of the litter CPU board
(p/n 3000–300–941). If voltage is not present,
check fuse F1 of the litter CPU board. Replace
fuse if necessary. If fuse is O.K. and voltage is not
present, check for 110 VAC at connector P1, pin
18. If 110 VAC is present, replace litter CPU
board (see page 115). If 110 VAC is not present,
check power junction board (p/n 3000–300–961) at
connector P1, pin 1 for 110 VAC. If voltage is not
present, check fuse F1. Replace as necessary. If
fuse is O.K., and 110 VAC is not present at con-
nector P1, check connector J1, pin 2 for 110 VAC
input from power cord. If 110 VAC is present at
connector J1 but not at connector P1, replace
power junction board as needed (see page 199 for
board location).
