LIFT POTENTIOMETER REPLACEMENT AND ADJUSTMENT (CONTINUED)
8. Lift up and out on the pot housing assembly to remove it from the lift housing.
9. Before installing the new pot on the bed, turn it clockwise until it stops. Turn it back counterclockwise
two full (360) revolutions. This allows a ”window” position for proper upper and lower limits.
10. Reverse steps 4−8 to install the new pot and pot housing assembly.
11. After installing the new pot, the “burn−in” procedure below must be followed.
NOTE
Be sure to maintain the pot position while installing.
LIFT POTENTIOMETER “BURN−IN” PROCEDURE
1. Unplug the bed power cord from the wall socket.
2. On the foot board control panel, hold down the Siderail Control Lights, Head Lock Out, and Up/Down Lock
Out buttons simultaneously.
3. While holding down the above three buttons, plug the power cord into the wall socket. The Lights button
on the foot board control panel should flash, indicating the bed is in the diagnostics mode.
4. On a bed without the Zoom power drive option, run both ends of the bed full down to a “hard stop”. On
a bed with the Zoom option, run both ends of the bed full up to a “hard stop”.
5. Hold down the Bed Motion Lock button until the light flashes.
6. Release the button and unplug the power cord from the wall socket.
7. Plug the power cord back in to the wall socket. Run the bed to full up, then full down to verify the bed
limits.
8. The distance between the floor and the top of the litter seat section on a standard Secure bed (without
a mattress) should be 16”− 16 3/8” with the litter fully down and 29 1/4” − 29 7/8” with the litter fully up.
The distance between the floor and the top of the litter seat section on a Secure Zoom bed (without a
mattress) should be 19.5” with the litter fully down and 30” − 30 1/4” with the litter fully up. The distance
between the floor and the top of the litter seat section on a Secure short bed with Zoom (without a mat-
tress) should be 20.5” with the litter fully down and 30” − 30 1/4” with the litter fully up.
NOTE
These values are for beds equipped with 6 inch casters. Add two inches to both measurements for beds
equipped with 8 inch casters.
