  • Page 113: Electrical Description

    Electrical Description Chapter 3: Theory of Operation Electrical Description The electrical power system is mechanically insulated from the metal parts of the bed. No additional electrical components, such as isolation transformers, are required to make this bed meet applicable electrical codes. The insulation materials are of the type that will not deteriorate to an unsafe level over an 18 year period with normal use.

  • Page 114: Hilow

    The hilow and head motors have manual crank capability to allow operation in the event of power failure on P8400 models without the CPR release only. The head has a release mechanism to permit flattening of this section of the sleeping surface on P8500 models and P8400 models with the CPR release only.

  • Page 115: Thermal Resets

    Electrical Description Chapter 3: Theory of Operation Thermal Resets Thermals are an integrated part of the motors, protecting them in the event that an overload condition occurs. They stop the motor automatically if it heats up to a certain temperature. The motor will not run again until the thermal is reset. All beds have automatic reset thermals.

  • Page 116: Patient Controls

    Electrical Description Chapter 3: Theory of Operation Patient Controls Patient operation of the various functions of this bed is accomplished by means of low voltage finger touch switches located in a convenient fixed position at both sides of the bed. These patient controls are affixed with the movable head section to give easy access as well as visual contact with the head and knee operating button, irrespective of the position of the head section elevation.
