Overview
Introduction
The LimbLogic VS is a remote-controlled vacuum suspension system. The Vacuum
Pump is mounted inline on a prosthesis to allow for complete integration without the annoyances of tubes into the socket.
LimbLogic VS operates quietly and features “Set and Forget” monitoring, which means that the system monitors the level of vacuum in the socket to maintain a secure and comfortable fit.
Vacuum System Function
Lower
Set Point
Upper
Set Point
User
Maximum
0 in-Hg
Vacuum Control Range
20 in-Hg
(System Maximum)
The system monitors the vacuum level and draws more vacuum as needed to maintain the level between a minimum value (the Lower Set
Point) and a maximum value (the Upper Set Point). The difference between the Lower Set Point and the Upper Set Point is called the
Vacuum Control Range. The Upper Set Point cannot be set higher than the User Maximum. The User Maximum cannot be set higher than the System Maximum of 20 in-Hg.
The prosthetist may adjust the User Maximum as well as the width of the
Vacuum Control Range. Both the prosthetist and the patient may adjust the Upper Set Point.
The optimum vacuum setting is different for each amputee. Keep in mind that a higher vacuum level is not always better. Higher vacuum levels require that the Vacuum Pump use more power and will therefore discharge the battery faster.

Overview
Detecting a Leak
If the leak indicator appears when the patient initially dons the prosthesis, the patient should restart the pump.
If the leak indicator appears frequently while the patient is walking, use the Diagnostic Kit (LLV-1300) to determine the source of the leak.
To resume automatic vacuum regulation after a leak has been detected:
• Press the center button on the fob until the hourglass symbol appears,
or
• Press the on/off button on the Vacuum Pump one time.
If the Sealing Sleeve is Punctured
The latex sleeves (LLS-3N, LLS-4N, or LLS-5N) in the
Diagnostic Kit are to be used ONLY as a diagnostic tool for locating the source of a leak. If a leak is fixed by replacing a sealing sleeve with a latex sleeve, then the patient should receive a new sealing sleeve immediately. The patient should NOT be sent home with a latex sleeve, because the mineral oil in the
Alpha gel causes the latex to lose its elasticity.
16
Overview
No Radio Connection
If the No Radio Connection indicator appears:
• make sure the Vacuum Pump has been turned on
• make sure the Vacuum Pump battery has been charged
• make sure the fob is within 3 feet of the Vacuum Pump
• make sure the fob is more than 3 inches away from the
Vacuum Pump
If the No Radio Connection indicator still appears, contact
Ohio Willow Wood.
Low-Battery Mode
If the Vacuum Pump battery has less than 15% of its capacity remaining, the Vacuum Pump enters a “stutter” mode.
(Stutter mode is when the pump quickly turns on and off when pulling vacuum.) Charge as soon as possible.
The fob will display the battery charging indicator when the unit is plugged into the charger.
Turning off the Vacuum Pump
Press the on/off button on the Vacuum Pump two times. The Vacuum
Pump will vibrate twice.
If the current vacuum level is near the current Upper Set Point, the
Vacuum Pump may skip the vibrations to prevent the vacuum level from exceeding the Upper Set Point.
17
Overview
Cleaning the System
Once a month, the patient should pour 1/8 cup of distilled water or rubbing alcohol into the socket, place the end of the exhaust port tubing into a cup, and activate the Vacuum Pump. Use ONLY distilled water or rubbing alcohol to clean the system.
Do not use acetone or similar chemicals to clean the system.
Please demonstrate this procedure for the patient before sending the patient home with the system.
Exposure to Water
The Vacuum Pump is waterproof in fresh water up to a depth of 10 feet or
3 meters for up to 12 hours. The Vacuum Pump should not be submersed in salt water. Be sure to dry off the Vacuum Pump if it is exposed to rain or other moisture.
The fob is not water resistant. Submersion of the fob will void the warranty.

Overview
Problem
Pressing the center of the button of the fob does not display the
LimbLogic VS logo.
Action
The fob battery may need to be reset.
Remove the back cover of the fob per the instructions in the Patient Information booklet, then remove and reinstall the battery. If the problem persists, the battery is likely dead and must be replaced per the instructions in the Patient Information booklet.
The blue LED light on the charger does not illuminate when plugged into the wall.
The pump makes a
“zip zip zip” sound as it controls the vacuum.
• The AC electricity to the wall outlet may not be turned on. Try plugging the charger into a different non-switched wall outlet or in another room.
• The configurable prong may not be seated properly in the back of the charger’s twopronged adapter. Unplug the charger from the AC outlet. Remove the charger’s prong using the sliding latch on the back of the adapter. Verify that the metal contacts are springy and are not completely flat against the adapter. Re-install the plug prongs.
The system is leaking, but not yet at a rate that triggers the Leak Detection symbol. Wash the sealing sleeve of debris around the sealing surface, and remove any dirt or debris from the proximal sealing gasket and the pump’s sealing surface. If the leak is still present, use the Diagnostic Kit (LLV-1300) to determine the source of the leak. Refer to the Diagnostic Kit instructions on the next page.

Diagnostic Kit Instructions
Start HERE if the leak is found AFTER the prosthesis has been delivered.
Start HERE if the leak is found BEFORE the prosthesis has been delivered.
Follow this process to evaluate the integrity of the
LimbLogic VS prior to fitting or to isolate the source of a leak in the system.
Have the patient don the prosthesis:
• fold down the top edge of the Alpha Liner
• use a latex sleeve from the kit instead of the Alpha Flex.
Activate the vacuum.
If the leak does NOT go away
For a socket
LAMINATED
Press the Suction
Pad against the proximal surface of the distal adapter with the dome side facing down.
Activate the vacuum.
If the leak goes away
The Alpha
Flex was the source of the leak.
For a THERMOPLASTIC socket
Press the Suction
Pad against the proximal surface of the distal adapter with the dome side facing up.
Activate the vacuum.
If the leak goes away
The leak was coming through the
socket walls.
Laminate a new socket with an inner layer of
PETG.
If the leak does
NOT go away
Renove the pump from the socket. Use the Diagnostic
Disc that is included with every pump to see if the leak is coming from the pump:
• Remove the protective tape from the Diagnostic Disc.
• Place the Proximal Gasket in the recess on top of the pump.
• Place the Diagnostic Disc on top of the Proximal
Gasket.
• Attach the pump with the Diagnostic Disc and
Proximal Gasket to the socket.
• Start the pump and make sure the vacuum does not bleed off.
If the leak does
NOT go away
• Make sure that there are two
Proximal Gaskets in place between the pump and the themoplastic socket.
• Make sure that the four M6 screws are tightened to 9 ft-lbs or 12 Nm.
• Make sure that the internal surface of the thermoplastic socket is flat and free of defects.
If the leak goes away
The leak is coming from where the socket meets the pump. Possible causes:
• The 4-Hole Distal Adapter was not attached to the socket using Fabtech 60 structural urethane.
• The pump was installed with the wrong bolts. If the 55 mm bolts for the thermoplastic adapter were used in a laminated socket, the bolts will bottom out before they can be appropriately tightened.
• The leak could be coming from the proximal sealing gasket. Make sure the gasket is the one that was provided by Ohio Willow Wood. Clean with isopropyl alcohol to remove any debris. If the gasket is torn, install a new one.
• The surface of the 4-Hole Distal Adapter and/or pump are damaged or dirty.
• The walls of the center hole could be leaking. Drill the hole out to 3/8", fill the hole with Fabtech 60 structural urethane, then drill out a new 9/32" hole.
If the leak does NOT go away
The leak was coming from the
Vacuum Pump.
Contact Ohio
Willow Wood.
To confirm that you have fixed the leak:
• Reassemble the pump and gasket to the socket.
• Activate the vacuum.

FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the LLVS is used exceeds the applicable
RF compliance level above, the LLVS should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the LLVS.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
Recommended separation distances between portable and mobile RF communications equipment and the LLVS
The LLVS is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
LLVS can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the LLVS as recommended below, according to the maximum output power of the communications equipment.
