Theory of Operation

Introduction

There are two Theories of Operation for the CareAssist™ Bed:

• Mechanical

• Electrical

The interaction between these subsystems lets all the operational functions be 
used. 

The electrical functions are driven by low voltage actuators.

Each of the subsystems is described separately in the following sections. The 
schematic diagrams are located at the end of this chapter.
