All power-operated functions are operated by push button controls. Each function has separate “up” and
“down” pushbuttons.
The user control panels are integrated into the head end split side rail modules, with the patient's controls
on the inside face and the nurse's controls on the outside. The patient's controls adjust backrest angle,
leg elevation and
Bio-Contour ; the nurse's controls adjust backrest angle, leg elevation and bed height.
The bed has attendant control panels (ACP) integrated into the foot end split side rails, from which the
power operated functions can be disabled; operation of the bed by the patient is thus at the discretion of
the carer. The ACP contains pushbutton controls for all bed movements including tilt (Trendelenburg and
reverse Trendelenburg), Auto-Chair and CPR.
The electrical actuators consist of a screw and nut assembly driven by a 24VDC motor and gearbox.
Power for the actuators is derived from an a.c. power supply located below the head end of the bed. The
power supply also houses the control electronics with the backup battery adjacent to it.
When the thigh section is raised, the kneebreak angle between the calf and thigh sections can be
changed manually. The default position is Fowler (calf section angled down) but this can be changed to
vascular (calf section horizontal). by lifting the calf section.
