Theory of Operation

The RESIDENT® Low Bed is electrically operated by an AC power supply. A
battery DC backup system is available as an option. Only the siderails must be
operated electrically. The bed functions (head up/down, knee up/down, or
hilow), can be operated manually.

Electrical System

The Repair Analysis Procedures (RAPs) for the RESIDENT® Low Bed are
designed to identify each electrical component as working or not working.
Except for the power cord, no voltage readings or continuity checks are
required to make this determination. A component that is diagnosed as not
working is removed and replaced with a known working model.

There are nine replaceable electrical components on the RESIDENT® Low
Bed: the electrical control/lockout box, the junction box, the automatic contour
control assembly, the head actuator, the knee actuator, the hilow actuator, the
hand pendant, and two siderail controls.

Electrical Control/Lockout Box

The electrical control/lockout box is located at the foot of the bed to allow the
caregiver convenient access to the lockout controls. The electrical control box
has no serviceable parts.

Electrical Connections

A replaceable power cord (A) brings 120V AC power from the power supply
into the unit (see figure 3-3 on page 3-6). The bed is always energized when
the power cord (A) is plugged into a 120V AC power supply.
