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 through
normal use.
Each bed is factory-tested for complete operation with and without a load.
Each bed is tested for insulation integrity and micro leakage currents. Before
shipment, each 115 volt model must have less than 65 microamperes of current
leakage when ungrounded. Each 230 volt model must have less than 90
microamperes of current leakage when ungrounded.
The supply cord is #16 AWG low-leakage, 3-conductor type STO. It extends
72" (183 cm) from the head end of the bed. The supply cord is UL-listed, and
the attachment plug cap is UL-listed and hospital grade.
All electrical components of the bed have been approved by UL for this
application.
The bed automatically tests its electrical circuitry to ensure that the system is
properly wired in regard to ground and correct polarity. Deficiencies in the
grounding or the polarity of the building wiring to this bed are automatically
indicated by the Ground Loss indicator light on the footboard control panel.
The Ground Loss indicator light also illuminates when the bed is used on
isolated power systems. This is a normal indication, if the electrical safety
check indicators are within specifications.
The Ground Loss indicator does not operate on 230 volt beds.
Motors
There are four individual motors to power the separate functions of the bed.
The hilow (bed up/bed down) and head motors have manual crank capability to
allow operation in the event of power failure.
All of the motors have a plug-in design to allow them to be easily and rapidly
removed from the bed in the event of motor problems. These motors are
designed and made especially for the individual functions they are to perform.
