5. Raise, and then lower the sleep surface using the hilow function. The bed
sleep surface stops and does not drift downward or coast.
Yes No
Go to RAP 2.1.
6. Raise the bed to the high position using the hilow function. Determine the
hilow up limit setting by measuring at the side of the bed from the floor to
the top of the mainframe (see figure 4-5 on page 4-12). The hilow limit
(LBU) measurement is 31" ± ½" (79 cm ± 12.7 mm).
Yes No
Adjust the hilow limit switch (LBU) (refer to procedure 4.4). If
this solves the problem, go to “Final Actions” on page 2-10.
Otherwise, contact Hill-Rom Technical Support.
7. Lower the bed to the low position using the hilow function. The bed stops
at the (LBD) limit stop. The bed height is 16" ± ½" (41 cm ± 12.7 mm).
Yes No
Adjust the hilow limit switch (LBD) (refer to procedure 4.4). If
this solves the problem, go to “Final Actions” on page 2-10.
Otherwise, contact Hill-Rom Technical Support.
8. If the bed has the Stow and Go® Foot Section installed, lower the bed to
the low position using the hilow function. There is at least 3" (76.2 mm)
clearance under the bed.
Yes No
Adjust the hilow limit switch (LBD) (refer to procedure 4.4). If
this solves the problem, go to “Final Actions” on page 2-10.
Otherwise, contact Hill-Rom Technical Support.
Trend-Like Position Functional Check
1. Position the bed into a mid height position with the hilow function.
Activate the Trend-Like position release handle at the head end of the bed,
and place the bed in and out of the Trend-Like position. The bed goes in
and out of Trend-Like position smoothly, and the sleep surface is secure
when the handle is released:
Yes No
Adjust the Trend-Like position sensing switch (refer to
procedure 4.9). If this solves the problem, go to “Final Actions”
on page 2-10. Otherwise, contact Hill-Rom Technical Support.
