LIFT POTENTIOMETER REPLACEMENT AND ADJUSTMENT (CONTINUED)
9. Lift up and out on the pot housing assembly to remove it from the lift housing.
10. 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.
11. Reverse steps 4 − 8 to install the new pot and pot housing assembly.
12. After installing the new pot, the “burn − in” procedure must be followed.
NOTE
Be sure to maintain the pot position while installing.
LIFT POTENTIOMETER “BURN − IN” PROCEDURE
NOTE
It requires two people to enable the diagnostics mode for the bed.
1. Unplug the bed power cord from the wall socket.
2. On the foot board control panel, hold down the bed motion lock button and the button to lock out the side-
rail controls for the knee. While still holding the buttons, plug the bed power cord into the wall socket.
Release the foot board buttons. The siderail control lights LED should be flashing to indicate the bed is
in diagnostics mode.
3. To “burn in” the Bed Up/Down limits, raise the bed completely up until it can’t go any farther. Press and
hold the “Bed Motion Lock” button. The “Bed Motion Lock” LED will light. Continue to hold the “Bed Mo-
tion Lock” button until the“Bed Motion Lock” LED flashes. The flashing LED indicates the limits have been
set. Release the“Bed Motion Lock” button and unplug the power cord from the wall socket to complete
the “burn in” mode.
4. Plug the power cord into the wall socket and verify the lift limits are set properly before returning the bed
to service.
5. If your bed has an IV Caddy, a lower limit must be burned in. Run the litter down to 19.5 inches. Hold
the Bed Up/Down Lock button until the light flashes.
CAUTION
Do not run the litter all the way down while in the diagnostics mode. Damage to the botton lift covers could
result.
