Electrical/Electronics Description
Line voltage is fed into the controller through the power
cord to the power supply mounted in the rear case of the
controller. It is important to disconnect the power cord at
the outlet before opening the controller case. Exposure to high voltage on the Power Supply PC Board is likely to occur
if it is electrically live.
The power supply converts AC line voltage, 100 to 240 VAC, to DC voltage to power the controller components,
including the main Controller PC Board that is mounted onto the front case. Alternately, the main Controller PC Board
may be directly powered by the battery pack. The Controller PC Board controls all functionality of the system and
includes the transducer and buzzer. It does not contain any high voltage. The buttons and indicator LED’s on the front
display of the controller are integrated into the membrane panel which connects to the Controller PC Board.
Covidien does not recommend any attempt to repair printed circuit boards. In manufacturing, extensive testing is
performed that cannot be duplicated in the field without specialized equipment. Improper repair could result in
patient or user hazards.
Pneumatic Operation Description
When the controller is turned on, the compressor operates and the valves are cycled to verify the garment type
selected by the user. After garment selection and verification has completed, an inflation cycle is initiated, releasing
air through the set of valves, mounted to a manifold. A transducer monitors the pressure in the garments. The
reading from the transducer assists the controller in adjusting the pump’s motor speed to deliver the proper pressure
to the garments in the appropriate amount of time.

Section V - Test Methods and Calibration
The Kendall SCD 700 Series Compression System
has various test modes that can be accessed by
the service technician. They are intended for use
by qualified personnel. To activate the test modes
follow these steps for entering “Test Access Mode”.
FIGURE 5 shows the user interface features used in
Test Access Mode.
• Plug the controller into an outlet supplying the
appropriate line voltage. Do not activate the
test modes while operating on battery power.
• Press the B Button at the same time while
turning the controller on. Hold thet B button
for a moment until test mode access can be confirmed visually
• The buzzer will beep and T1 will be underscored and will illuminate signifying “Test Mode T1”.
• The user can cycle through the test modes by pressing the Right Arrow button. Each test mode is indicated by
the slider under the corresponding test modeand the selected test mode is shown at the bottom of the screen for
clarity. Pressing the Right Arrow Button with the last test mode number illuminated alarm history will cycle the
test mode back to Test Mode T1.
