Indications
The SCD EXPRESS
TM
Compression System is designed to apply intermittent pneumatic compression to increase venous blood flow in
at-risk patients in order to help prevent deep vein thrombosis and pulmonary embolism. The System consists of the Controller, the Tubing Sets (provided
with the Controller) and single-patient use garments (purchased separately from this Controller). The garments, both leg sleeves and foot cuffs,
compress the limbs to enhance venous blood movement. After the compression, the Controller measures the time it takes for the limbs to refill with
blood and waits that period of time before the next compression is initiated.
Leg Compression
The use of the SCD EXPRESS Compression System with Leg Sleeves is indicated for:
1. Deep vein thrombosis and pulmonary embolism prophylaxis.
Foot
Compression
The use of the SCD EXPRESS Compression System with Foot Cuffs is indicated for:

• Place the Co
ntroller on the footboard via the bed hook or place it on a horizontal surface appropriate for the environment, such as on a table, within
reasonable proximity to the point of use. Be sure to allow adequate air flow to the vents located on either end of the controller.
• The controller can operate with one or two garments attached to the patient.
• Plug the tubing set(s) into the back of the controller. Route the tubing toward the patient’s limbs, being careful to leave access ways clear and
eliminate tripping hazards.
• Plug the tubes into garment(s) wrapped onto the patient’s limbs.
•
M
atch the left and right ports with the left and right limbs of the patient. Although the operation of the controller
is not affected, troubleshooting can
be easier. Check tubing set(s) for kinking and secure attachment at the controller and the garment(s).
•
Plug
the
controller power cord into a properly grounded hospital grade receptacle.
Start-up
• Press the Power On/Standby button to begin normal operation. If using leg sleeves, no further user intervention is required unless there is a fault
condition detected or if therapy must be discontinued.
• The Controller will beep and then flash all the LED’s.

•
An automatic valve and pump test will be quickly performed as the system tests microprocessor function and system memory.
• The pump will begin to operate as part of the Garment Detection procedure.
•
Detection of inoperative LED’s and the audible alarm function at start-up is the user
’s responsibility.
Garment Configuration & Detection
After startup, the Garment Configuration procedure allows the user to select when foot compression is required at either of the two Controller ports:
•
On the front display, the Port A Leg and Port B Leg indicators for both ports will be flashing green to indicate the
default garment configuration (leg
compression).
•
Pressing a port configuration button will cause the corresponding port
’
s Leg indicator to turn off and the Foot indicator will be lit to signify foot
’s Leg indicator to turn off and the Foot indicator will be lit to signify foot ’
compression. The port configuration buttons must be pressed for each port that is connected to a foot cuff to turn on the corresponding Foot
indicator(s).
NOTE:
Leg sleeve compression is the default garment configuration when the Controller is first powered on. Therefore, the configuration
buttons do
not have to be pressed to begin compression therapy when leg sleeves are being used.
The configuration buttons need to be pressed only when foot compression is to be used.
Also after startup, the Controller immediately begins conducting the Garment Detection procedure at each port to determine if the garments have been
properly attached to the controller:
•
If necessary, the port configuration buttons may be pressed again to turn the Foot indicator off and revert back to leg compression.
•
During Garment Detection, the compressor and valves are operating and air is delivered out the Controller ports to detect the number and type(s) of
garment(s) connected [Leg Sleeve(s) and/or Foot Cuff(s)].
•
If the Controller senses a properly attached garment and the type of garment detected matches the User-selected garment (or the default)
configuration, then the corresponding Port Status indicator (Leg or Foot, A or B side) on the front display will be lit green.
•
If the Controller senses a properly attached garment but the type of garment detected does not match the User-selected garment (or the default)
configuration, then a Garment Mismatch alarm is triggered. Garment Mismatch errors can be corrected by pushing the corresponding Port
Configuration button to change the User-selected garment type (Leg or Foot).
•
Once the Garment Detection procedure is completed and any garment mismatch errors are addressed, the Port configuration buttons will be disabled
and normal operation begins by starting the compression therapy.
•
If only one Controller port is connected to a garment for single-limb compression, then the User-selected garment (or the default) configuration
setting
(Leg or Foot) for the open port will be ignored and both the leg and foot indicators will be turned off after Garment Detection
.
•
If any garments are not properly detected or if no garments are attached to the Controller, the system will alarm until it is turned off. Check the
garment application and tubing connections then restart the Controller if necessary.
NOTE:
If a garment is attached anytime after the Garment Detection procedure has started, the system must be restarted to ensure that the
proper therapy will be applied to the limb(s).

EN-4
Normal Operation
• Verify that the corresponding Port Status Indicators are green for each disposable garment attached to the controller.
•
After garments have been
successfully detected, the Controller begins the process of applying intermittent compression alternating from on
e port to
the other if two garments are attached. Otherwise, the controller applies compression to only one port when one garment is attac
hed.
•
On successive cycles, the controller automatically adjusts its operating parameters to maintain set pressure.
Pressure Settings
•
The Controller features microprocessor-controlled automatic pressure adj
ustment.
•
The pressure setting depends on the type of garment: 45 mmHg for Leg Sleeves; 130 mmHg for Foot Cuffs.
Vascular Refill Detection
•
The SCD EXPRESS Compression System incorporates Tyco Healthcare’s patented “Vascular Refill Detection” method to customize the therapy for each
patient’s physiology. This system measures the time it takes for the veins in the limb to refill after having been compressed
by the system. The time is
then used in subsequent cycles as the time between compressions.
• The vascular refill detection method is used when first powering on the System after it reaches set pressure and every thirty minutes thereafter.
• The hourglass-shaped Vascular Refill Indicator on the front display will be illuminated during a measurement cycle.
• The method works best when the patient is still, however it will accommodate movement.
• If an error is detected during any measurement or if the compression is not within the System pressure specifications, the refill time measurement
will
be repeated after the next compression cycle.
• The time between compressions on the same limb will never be shorter than twenty seconds or longer than sixty seconds.
• If both Controller ports are being used, then the longer of the two measurements will
be used to adjust the time between cycles.

Portable Controller Configuration
•
The SCD EXPRESS Compression System Controller can be configured without the bed hook for easier portability. The System can also be used
without
the cord cover door so that the power cord can be disconnected at the Controller instead of at the AC power wall outlet.
• An optional Shoulder Strap for the SCD EXPRESS Compression System is available as Reorder Code 9527.
NOTE:
Removal of the bed hook and the cord cover door is described in Section VI – Disassembly and Reassembly.
Section II -
Battery Operation
The SCD EXPRESS Compression System is designed to operate normally on AC line power or DC battery power without interruption. If the Controller
is equipped with the optional battery pack there are three Battery Status Indicator LED’s used to represent the charge level of the battery. Once the
Controller is powered on, it may take the system a few seconds to establish communication with the battery and display the charge level. If the
Controller is not connected to a battery then the indicator lights will remain off.

EN-5
NOTE:
To prevent a potential shock hazard, the battery compartment should not be left vacant while operating the SCD EXPRESS Compres-
sion System. The battery pack, or a dummy pack (if so equipped), must be installed in the controller to prevent the user from having access
to the battery’s electrical connection.
T
he battery pack
for the SCD EXPRESS
Compression System is optional. To order
a
new or replacement battery
please contact Kendall Customer Service.

Charging the Battery
The battery will begin charging as soon as the unit is plugged into an AC power source. The amount of time required to charge the battery will vary
depending on the battery’s overall condition, age, and the controller’s state during charging. For example, charging a new, fully drained battery will
take approximately 4 hours with the controller on standby and 8 hours with the controller powered on. The Battery Status indicators should always be
used to determine the state of charge for the battery. A fully charged battery will typically provide 6-8 hours of operation time depending on the sleeve
configuration, sleeve application, and the battery condition.
NOTE:
If the operation time on battery power is extremely short the battery should be returned for service or replace
ment.
NOTE:
The battery may sustain permanent damage and become unrecoverable if it is left
unused for extended periods of
time. It is
recommended that
the battery pack be stored with a minimum charge of 50% and kept near 25
° C
(77
°F)
if prolonged storage is necessary.
* With 15-40 minutes of battery charge left, an alarm will sound in a sequence of three beeps once every two minutes. Once
there is less than 15 minutes of battery charge left, the alarm will sound continuously.

•
Do not touch or ingest any leaking electrolyte. If contact occurs, rinse skin and/or eyes immediately and seek medical attention if irritation develops.
If ingested, contact local poison control center.
•
Do not open battery, dispose of in fire, or short circuit. Doing so may cause the battery to ignite, explode, leak, or become hot and cause personal
injury.
•
Dispose of improperly working or damaged battery packs according to local regulations.
•
Charge only with specified chargers according to Kendall’s instructions.
Section III - Fault Conditions and Troubleshooting
When the microprocessor detects a fault condition, it interrupts the normal operation of the Controller, deactivates all valves to vent the air from the
garment(s), displays a f
ault code,
garment(s), displays a fault code,garment(s), displays a f
and sounds an audible alarm. If a Garment Mismatch alarm is triggered the user may remedy the problem by
pressing the corresponding port configuration button(s). All other alarms will remain active until the Controller is turned off, or the battery runs out of
charge (if operating on battery power).
• The most common Controller alarm is the Garment Pressure alarm, indicated by flashing red Port Status Indicator(s). Garment Pressure alarms
can usually be remedied by checking the disposable garment(s) for proper application and tubing set connection(s) for any leaks or kinks, and then
restarting the System. However, if the alarm condition persists or if the Servi
ce Required Error indicator is illuminated then the Controller should be
returned for service
.
Watchdog Circuit
•
If the microprocessor cannot continue normal function, the watchdog circuit will trip. This causes the Controller to go into reset and restart normal
operation.
• If the cause of the disruption is still present, the unit will continue to attempt to reset, which will cause the alarm to sound once every second.
• If the cause of the disruption was transient, such as a high energy RF pulse, the Controller will restart and continue normal operation.

Section IV - Service and Maintenance
This service manual is intended for use as a guide to technically-qualified personnel when evaluating System malfunctions. It is not to be construed as
authorization to perform warranty repairs. Unauthorized service will void the warranty.
Introduction
The SCD EXPRESS Controller contains no user serviceable parts. User maintenance is covered in the sections that follow. All other maintenance must be
performed by appropriately qualified service technical personnel.
Service technicians should be familiar with the operator’s portion of this manual and the operating principles of the SCD EXPRESS Compression System.
If a Controller is to be returned to Kendall for service, a description of the operating conditions and the fault code displayed should accompany the unit.
The fault codes displayed by the Controller are useful in diagnosing service problems.
This manual describes service procedures to the board level, with an exploded view of the Controller shown in
Figure1. If a component failure on a circuit board is suspected, the unit should be returned for service. It is recommended that the system be returned
with the circuit board in place, as removal of the board(s) involves additio
nal risk of mechanical damage and damage from electrostatic discharge (ESD
).

Fan Screen and Ventilation
CAUTION
:
Unplug the Controller and remove the battery pack (see Section VI) before fan screen maintenance.
It is very important that the fan screen be cleaned as required to ensure continued trouble-free operation. The Controller should never be run without
the fan screen in place. To clean the fan screen, follow the instructions later in this manual in the “Fan and Screen (Removal/Installation)” Section to
first remove the fan screen. Brush any loose dirt and lint from the surface of the screen. Reinstall the fan and screen, making sure the gasket m
aterial is
oriented so as to prevent the screen from touching the fan directly.
During system use, obstruction of the fan cover and vents should b
e avoided. Free flow of air is necessary to prevent overheating and premature
component failure.
Fuses
CAUTION:
Unplug the Controller
and remove the battery pack
(see Section VI)
before replacing the fuse(s).
Blown fuses should only be replaced by those indicated on the power supply board near the location of the fuses at the AC inlet. Use only 1.6 A,
250 VAC, 5x20mm Slo Blo fuses. The use of fuses that have the Semko and/or VDE marking is preferred. If a fuse blows a second time, it should be
presumed that the Controller is defective and requires further service. Please contact your service center. Fuses are not accessible from the outside of the
controller. Refer to the Disassembly/Reassembly pr
ocedures later in the manual. The fuses are located on the power supply board as part of the
power
inlet module under the fuse cover.
Electrical Safety
CAUTION:
Be sure the Controller is disconnected from the power source (AC line power and DC battery power) before any disassembly. A potential
SHOCK HAZARD exists when the front cover is removed even with the unit turned off.
NOTE:
T
he power supply cord/plug serves as the electrical supply mains disconnect device.
The system should be periodically inspected to ensure its electrical safety. Check the resistance of the power cord ground from the plug to the IEC
60320 connector. This resistance should not exceed 0.1 ohm. If ground resistance exceeds this value or the insulation integrity of the unit has been
compromised through mechanical damage, the Controller should be returned to a service center for testing and repair
.
compromised through mechanical damage, the Controller should be returned to a service center for testing and repair.compromised through mechanical damage, the Controller should be returned to a service center for testing and repair
* The SCD EXPRESS was designed to provide sufficient isolation inside the controller between all exposed metal components and the electrical
supply mains. As a result there is no externally accessible ground on the device. The recommended electrical safely test for proper grounding is a
resistance check of the power cord ground.

Cleaning
The Controller cabinet can be cleaned with a soft cloth dampened with water. If necessary, a mild disinfectant and/or detergent can be used; excess
fluid should be avoided. The Controller should be wiped with a clean, dry cloth afterward. Do not immerse in any liquid. Do not use products
containing ammonium chloride, acetone or other aromatic solvents, as those chemicals will degrade the integrity of the case and cause it to become
embrittled and possibly crack.
The SCD EXPRESS Compression System cannot be effectively sterilized by liquid immersion, autoclaving, or ETO sterilization, as irreparable damage to
the System will occur.
Electrical/Electronics Description
Line voltage is fed into the controller through the power cord to the power supply mounted on the Power Supply PC Board 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 optional 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.
Kendall 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 determine which type of garment is connected. After garment
detection 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 SCD EXPRESS Compression System has various test modes that can be accessed by the service technician. They are intended for use by qualified
