The control box lockout is located at the foot end of the bed. The position of
each control knob on the control lockout is pictorially labeled to indicate each
governing function and the locked/unlocked position. See “Automatic
Contour” on page 1-22.
Motor Actuators
There are three separate motor actuators which provide hilow, head, and knee
operation. Each is built to withstand the common hazards of spills and cleaning
liquids under normal conditions. These motor actuators are a plug-in design for
easy removal in the event of problems. Each is specially designed for its
individual function and has the following characteristics:
• 24 volt, DC motor
• Electronic overload protection, microswitch motor cutoff
• Totally enclosed, impact resistant motor housing
• Permanently lubricated
• Precision-rolled acme spindle for linear actuation of stainless steel piston
• Heavy-duty ball bearing spindle mount
• Flexible clutch drive to reduce vibration and noise
NOTE:
The battery pack accessory can provide emergency operation of the actuators
to position the bed in event of a power failure.
Specifications for these motor actuators are as follows:
Hilow
• 12.60" (32.0 cm) actuator stroke
• 20 1/4" (51.4 cm) retracted length
Head
• 7 1/4" (18.4 cm) actuator stroke
• 46.38" (117.8 cm) retracted length
Knee
• 2.88" (7.3 cm) actuator stroke
• 39 1/4" (99.7 cm) retracted length
