This bed has 2 motors for the HI/LO function. If one of the HI/LO motors is not moving bed
up or bed down:
a) Before removing any motor cables, try to re-synchronize the HI/LO function by following the steps
in section “B” below. After re-synchronizing, continue with next step if the problem continues.
b) If bed still does not move up / down remaining horizontal:
Possibility of a bad HI/LO motor or Control box. Unplug power cord from wall. At the control box,
switch the HI/LO motor cable for the potentially bad motor with the cable for the head motor (in port
#1 of the Control box). Re-plug bed power cord into wall. Push Head up / down buttons on hand
control. If HI/LO motor still does not run, replace that HI/LO motor. If HI/LO motor does run when
pushing the head up / down buttons, try plugging the second HI/LO motor cable into the Head motor
port on the Control box. If that HI/LO motor does not run, replace that HI/LO motor. If both first and
second HI/LO motors work when plugged into the Head motor port, replace the Control box.
B. IF NEITHER HI/LO MOTOR OR ONLY ONE HI/LO MOTOR WORKS
On the Hand Control Pendant,
simultaneously press and hold both
HI/LO Up and HI/LO Down buttons (Control
Box should start beeping) for approximately
five seconds until beeping stops. Release the
buttons, then press the HI/LO Down button
and hold until bed is lowered completely into
the lowest height position. When
both
HI/LO
motors reach their lowest position, the HI/LO
motors will automatically resynchronize.
