MOTION INTERRUPT SWITCH REPLACEMENT
Required Tools:
#2 Phillips Screwdriver 5/16” Nut Driver 3/8” Socket Wrench
OR
T27 Torx
NOTE
Because of fastener changes, it will be necessary to use either a 3/8” socket wrench or a T27 Torx to remove
the bolts holding the ground straps to the motion interrupt pan and a Phillips screwdriver or a T27 Torx to
remove the bolts securing the litter access panels.
Procedure:
1. Unplug the bed power cord from the wall receptacle.
2. Using a 3/8” socket wrench or a T27 Torx, remove the two bolts holding the ground straps to the motion
interrupt pan at the foot end of the bed.
3. Using a 5/16” nut driver, remove the two bolts holding the motion interrupt pan to the litter and remove
the motion interrupt pan.
4. Using a #2 Phillips screwdriver or a T27 Torx, remove the four screws securing the litter access panel
at the end of the bed needing service and remove the panel.
5. Disconnect the two wires at the switch being replaced.
NOTE
Take note of the terminals being used on the switch so the wires will be attached properly to the new switch.
6. Squeeze the retention clips on the switch and push down on the switch to remove it.
7. Reverse the above steps to install the new switch.
8. Activate the motion stop system to assure it is functioning properly: press and hold down the BED DOWN
key. As the bed lowers, lift up on each corner of the motion interrupt pan individually and assure the down-
ward motion stops each time. Release the pan and allow the downward motion to continue.
