Important: Do not ignore unanswered questions. You have the right to understand the product and all aspects of its operation. If necessary, please contact Motion

Concepts for information regarding any questions or concerns expressed.

Motion Concepts Power Positioning Systems are designed to accommodate a wide range of user needs. Only the dealer and the health care professional can ensure that the system meets your individual requirements. It is the dealer’s responsibility to ensure that the wheelchair and the power positioning system are set up properly and safely for your specific needs.

ABILITY

By changing your seating position (tilting, reclining, or elevating), you are changing the stability characteristics of the wheelchair. It is very important that the system is set up so that it is stable in all seating positions. When evaluating stability, remember the following:

Most TRx systems can be mounted onto the powerbase in various forward and aft positions. Make certain that the position selected provides you with maximum stability over the full range of seating positions.

Consider all personal gear and accessories (backpacks, vent systems, extra batteries, etc..) that will be carried on the wheelchair. For example, a loaded backpack, attached to the back of the seating system, can significantly reduce the rearward stability of your wheelchair.

Consider the backrest being used. For example, a recessed back can shift your center of gravity back and significantly reduce the rearward stability of the wheelchair . Conversely, a thick back cushion will shift you forward and reduce the wheelchairs forward stability.

If using a back other than Motion Concepts, check with manufacturer to ensure it is suitable for power positioning system applications.

Consider the seat cushion being used. Athick seat cushion will raise your center of gravity and reduce the wheelchairs stability in all directions.

All TRx systems are equipped with drive lockouts. Make sure this is set so as not to compromise your stability while driving.

All power-bases have programmable controllers which allow adjustment of the maximum acceleration and deceleration of the wheelchair. Make sure that these are set to an appropriate level for the system and for you, the user.

Ensure all medical conditions are considered when setting up your wheelchair. Involunt ary muscle movement such as spasms may affect the stability of the wheelchair, especially when the seating system is in a tilted or reclined position.

When a system is fully tilted or reclined, the front wheels of the powerbase should never come off the ground. If this occurs, please contact the Motion Concepts Technical Service Department immediately to resolve the issue.

The most important link in the delivery chain is you, the end user. You must be satisfied with the product in terms of function, safety and aesthetics. No sale is complete until you have received thorough training in all aspects of the care and use of the system.

Several factors must be considered when determining the Total User Weight and the Wheelchair Weight Capacity. To obtain the weight capacity data from the base manufacturer, please refer to your Powerbase Owners Manual. Please refer to the Weight Capacity Calculator outlined below in order to calculate the total user weight and the wheelchair weight capacity.

WARNING! The total user weight should never

exceed the wheelchair weight capacity or the

power positioning system (PPS) weight capacity.

ii) Power Positioning System (PPS) Weight Capacity

The weight capacity of the power positioning system can be obtained from Motion Concepts by contacting our Customer Service department. Insert the specified PPS Weight Capacity into the Weight Capacity Calculator (p.7) in order to verify that the Total User Weight does not exceed the PPS Weight Capacity.

i) Power Positioning System (PPS) Weight

The weight of a specific power positioning system can be obtained from Motion Concepts by contacting our Customer Service department*. Insert the PPS Weight into the Weight Capacity Calculator (p.7) to verify that the Total User Weight does not exceed the calculated Wheelchair Weight Capacity.

*Note: If a suitable weight scale is available at the Dealer facility, the PPS Weight can be readily determined by simply weighing the TRx Seating System prior to installation.

BBAATTERIES

TTERIES

DO NOT use the CHARGE LEVEL INDICATOR on a JOYSTICK DISPLAY to determine the existing battery charge. The joystick display indicates SURFACE VOLTAGE only, and may not be the true charge.

(This can be likened to charging a cell phone; if placed on its charger for a brief time, a cell phone display will often indicate that the batteries are fully charged, however the cell phone quickly goes dead once it is used).

Heavily depleted batteries require more time to recharge. Insufficient charge time may result in the supply of LOW VOLTAGE BATTERY OUTPUT to the electronics of the power positioning system. Low voltage output can pro- duce LONGER DUTY -CYCLES and OVERHEATING, which will REDUCE THE LIFE-CYCLE of these electronics.

Important Infor mation on Batter y Char ging:

WARNING! For detailed information on the charging, handling and care of your powerbase batter-

ies, please be certain to read and carefully follow the instructions provided by the powerbase manufacturer and the battery charger manufacturer.

RECOMMENDED CHARGING PROCEDURES: Normal Char ging: Allow eight (8) HOURS for normal charging.

(Note: to prolong the life of a battery

frequent charging is recommended, rather than only charging when necessary).

Heavily Depleted Batteries: Severly discharged batteries may require in excess of sixteen (16) HOURS to be properly charged and equalized.

(Note: be certain to understand the charge status indicators on

the battery charger- refer to the charger manual).

Note: Smaller ON-BOARD CHARGERS are NOT SUFFICIENT to recharge rehab-style power products. Batteries that require more frequent charging or take longer to charge than normal, may need to be replaced.

WARNING!: Currently there are no standards approved for tie-down systems in a moving vehicle of any type to transport a person while seated in a power wheelchair. Do not sit in your wheelchair while it is in a moving vehicle. Although your chair may be equipped with a positioning belt, this belt is not designed to provide proper restraint during motor vehicle transport. Anyone travelling in a motor vehicle should be properly secured in the motor vehicle seat with safety belts securely fastened.

3.0 Safety Precautions

Important!- Motion Concepts disclaims all responsibility for any personal injury or damage to property that occurs as a result of improper or unsafe use of the TRx system or the wheelchair on which the system is installed.

WARNING!: The following guidelines should be adhered to while operating your TRx

power positioning system to ensure safe operation:

 Never transfer in or out of your wheelchair with the power on.  Always check your surroundings before operating your TRx system. Make sure that the way is

clear of obstructions through the full ranges of travel of the system before operating any function. Do not operate the system while it is underneath a table, desk, or other obstruction.

 Never operate your TRx system while driving your wheelchair.  Never operate your TRx system while on an incline.  Never drive your wheelchair with the drive lockout system disabled or set beyond the maximum

20 degrees.

 Never allow your TRx system to be used as a tie-down point in a vehicle.  Never allow your wheelchair to be lifted by any part of the TRx System.  If you have a system with anti-tipper lockouts, be aware of when these lockouts engage. Make

sure to drive very carefully when driving your wheelchair with the anti-tipper lockouts engaged. For more information refer to Section 8.0- Safety Lockout and Limit Switches in this manual.

 When tilted or reclined back, prevent your arms from extending back beyond the backrest. This

could shift your center of gravity enough to cause the wheelchair to become unstable. (Read and follow the warnings/specifications in your powerbase manual on the subject of leaning).

5.0 Power Positioning Functions

Tilt

The tilt function causes the whole seat, including the back and armrests, to rotate back around a fixed pivot.

CG (Centre of Gravity) Tilt

The CG tilt function compensates for weight shift by sliding the pivot axis and entire seat assembly forward as the seat tilts back.

Recline

The recline function causes the position of your back to change by changing the angle of the backrest with respect to the seat pan.

Precline

The precline function is similar to the recline function, but depending on the system may allow up to 30° of forward recline (creating a lean-forward position). The range of recline is decreased approximately by the number of degrees of precline.

Anterior Tilt

The anterior tilt function causes the whole seat, including the back and armrests, to tilt forward around a front pivot. The degree of anterior tilt available, up to a maximum tilt of 30°, will depend on the system. This function aids in forward standing transfers.

Extended Shear Reduction (ESR)

ESR works in conjunction with recline to reduce the shear movement between you and the backrest. This is accomplished using a linkage that slides the backrest down on the backposts as the back reclines.

Power Sliding Back (PSB)

The switch operated PSB allows the back height to be adjusted to improve positioning and shift body weight. The PSB may also be synchronized to operate in conjunction with the recline function.

Power Elevating Seat (PES)

This functions allows you to elevate your entire seating system by up to 8 inches.

Power Elevating Le gr ests

There are 3 configurations for power legrests:

i) Combined:

the legrest actuators are programmed to elevate in unison keeping your right and left

legs at the same height.

ii) Synchronized:

the legrests actuators are programmed to elevate in conjunction with the power recline function (Note: legrests can also be synchronized with power tilt if specified). The legrests elevate automatically as the seating system reclines (or tilts).

iii) Independent:

the legrest actuators are programmed to elevate separately to allow you to position

your right and left legs at different heights, independent from each other and the back position.

Pushrod Leg rests (Mechanical)

The pushrod legrests are synchronized with the power recline and operate via a mechanical linkage. A pushrod elevates the legrests automatically as the seating system reclines. No additional actuators are required.

Drive Lockout (DLO) Limit Switch

All TRx systems with tilt and/or recline functions are equipped with a drive lockout limit switch. This switch prevents the drive motors from operating if the back is positioned beyond a pre-determined angle. The rec- ommended drive lockout angle is 15° to 20° from the vertical. The limit switch should be set to the angle that best meets the overall stability and individual needs of the user, but should not exceed the maximum 20° angle.

All TRx systems with power elevating seats are also equipped with a drive lockout limit switch. These systems typically use a microswitch to prevent the drive motors from operating once the seat begins to elevate. The microswitch should engage the Drive Lockout when the seat actuator has been elevated beyond a recommended 1/2” limit [measured from the seat’s home (lowest) position].

Tilt Limit Switch

All TRx systems, except those using our basic single motor function relay box, can be equipped with a tilt limit switch. The function of this switch is to prevent the back angle from extending beyond a pre-set angle. Ultimately the angle should be set to meet the individual needs of the user. However, the recline angle should never extend beyond a recommended 5° from the horizontal. The limit must also be checked to ensure that with any combination of tilt and recline, there is absolutely no possibility of interference between the back of the TRx system (or any accessories located on the back), and the wheelchair base.

CAUTION! When setting tilt limits remember to consider the size and location of any personal gear that will be carried on the wheelchair, as it could cause interference with tilt or recline motor functions.

Elevating Seat Lockout Switch

All TRx power elevating seat systems, when combined with tilt and/or recline functions, are equipped with an elevating seat lockout switch. This limit switch prevents the PES actuator from elevating or descending when the system is in a tilted or reclined position. The recommended lockout limit should not exceed a maximum of 8° from the seating system’s original pre-tilt (“home”) position, and it is recommended to be

set between 3° and 8°.

Anti-Tipper Latch Limit Switch

Certain powerbases come equipped with anti-tip devices that latch in order to ensure stability during tilt, recline or elevating functions. For these powerbases, our TRx systems are engineered to control and engage the anti-tipper latch through the use of a limit switch. The recommended limit switch settings are determined by the type of power positioning system:

i) Tilt-Only: set switch to engage the anti-tippers when seat angle is at 10° (regardless of pre-tilt angle). ii) Tilt/Recline & Recline-Only: set switch to engage the anti-tippers when the back reclines 10° (from upright) iii) Power Elevating Seats (PES): set switch to engage the anti-tippers when seat actuator has elevated

beyond a recommended 1/2” limit.

In some instances, an anti-tipper latching system is added to the power base as part of the installation in order to ensure the stability of the power positioning system is maintained.

8.0 Safety Lockout and Limit Switches

WARNING! The angle at which the limit switches are set is critical to the safe operation of the power positioning system. Motion Concepts will not be liable for any injuries or damage sustained when adjustments are made beyond the factory recommended range. These switches should only be adjusted and set by a trained Technician.

Important: Please refer to the Motion Concepts General TRx Set-up Manual for detailed instructions on setting and adjusting Limit Switches

TION

Important: To maintain the smooth operation of your TRx Power Positioning System, occassional

lubrication of the slide channels and/or the Power Elevating Seat (PES) actuator* is necessary. All Motion Concepts Seating Systems are pre-lubricated at the factory using Sil-Glyde

Brake Lubricant . Testing has proven this lubricant to be extremely effective in our system applications. Motion Concepts strongly discourages the use of any other grease or lubricants. Apacket of Sil-Glyde

Brake Lubricant (P/N- TRM0464)

is provided with each TRx Seating System (additional lubricant is available from Motion Concepts).

Slide Channel

i) Slide Channel Lubrication

Lubricate the left & right slide channels as needed by applying a thin coat of Sil-Glyde®to the upper and lower surface of each slide channel.

ii) PES Actuator Lubrication

Riser Tube

Lubricate the power elevating seat (PES) actuator as needed by applying a thin coat of Sil-Glyde®to the surface of the riser tube.

WARNING! For det ailed information on charging your powerbase batteries, please be certain to read and

carefully follow the instructions provided by the powerbase manufacturer and the battery charger manufacturer.

DO NOT use the CHARGE LEVEL INDICATOR on a JOYSTICK DISPLAY to determine the existing battery charge. The joystick display indicates SURFACE VOLTAGE only, and may not be the true charge.

Important Infor mation on Batter y Char ging:

NORMAL CHARGING:

Allow 8 hours for normal charging.

(Note: to prolong the life of a battery frequent charging is recommended,

rather than only charging when necessary).

HEAVILY DEPLETED BATTERIES:

Severly discharged batteries may require in excess of 16 hours to be properly charged and equalized.

(Note: be certain to understand the charge status indicators on the battery charger- refer to the charger manual).

Recommended Charging Procedures:

Note: Smaller ON-BOARD CHARGERS are NOT SUFFICIENT to recharge rehab-style power products. Batteries that require more frequent charging or take longer to charge than normal, may need to be replaced.

11.0 Electro-MMagnetic Interference

Electromagnetic Interference (EMI) From Radio Wave Sources

Power positioning systems may be susceptible to electromagnetic interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) transmitters, two way radios and cellular phones. The interference (from radio wave sources) can cause the power positioning system to function by itself, or activate in unintended directions. It can also permanently damage the control system.

The intensity of the interfering EM energy can be measured in volts per meter (V/m). Each power positioning system can resist EMI up to a certain intensity. This is called its "immunity level", the higher the immunity level, the greater the protection. At this time, current technology is capable of achieving at least a 20 V/m immunity level, which would provide useful protection from the more common sources of radiated EMI.

There are a number of sources of relatively intense electromagnetic fields in the everyday environment. Some of these sources are obvious and easy to avoid. Others are not apparent and exposure is unavoidable.

The sources of radiated EMI can be broadly classified into three types:

1. Hand-held portable transceivers (transmitters-receivers with the antenna mounted directly on the trans-

mitting unit) - examples include: cellular telephones, citizen band (CB) radios,"walkie-talkies", security, fire and police transceivers and other personal communication devices. NOTE: Some cellular telephones and similar devices transmit signals while they are "ON", even when they are not being used.

2. Medium range mobile transceivers, such as those used in police cars, fire trucks, ambulances, and taxis.

These usually have the antennae mounted on the outside of the vehicle.

3. Long range transmitters and transceivers, such as commercial broadcast transmitters (radio and TV

broadcast antenna towers) and amateur (HAM) radios.

Note: Other types of hand held devices, such as cordless phones, laptop computers, AM/FM radios, TV sets, CD players, cassette players, and small appliances such as electric shavers and hair dryers, so far as we know, are not likely to cause EMI problems to your power wheelchair.

Electromagnetic Interference War ning

WARNING! It is very important that you read this information regarding the possible

effects of electromagnetic interference on your TRx power positioning system.

In addition, operation of power positioning systems can create electro-magnetic interference, the effect of which cannot be determined. Please make sure to read the associated warnings in the owner's manual for your power base.

TRD0000, TRx Owner’s Manual- Rev. 5.0, January 20, 2005

Electromagnetic Interference War ning ............................................. continued

Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source) , the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to unintentionally bring high levels of EM energy very close to the control system while using these devices.

WARNING!: The warnings listed below are recommended to prevent possible interference with the control system of the power positioning system.

 Do not turn on personal communications devices, such as cellular phones, or operate hand-

held transceivers (transmitters, receivers), such as citizens band (CB) radios, while the powered wheelchair is turned on.

 Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close

to them

 If unintended movement occurs, turn the wheelchair off as soon as it is safe to do so.  Be aware that adding accessories or components, or modifying the power positioning sys-

tem may make it more susceptible to EMI. Note: There is no easy way to evaluate their effect on the overall immunity of the powered wheelchair.

 Report all incidents of unintended movement of the power positioning system to the manu-

facturer, and note whether there is a source of EMI nearby.

CAUTION! Modification of any kind to the electronics of the power positioning system as manufactured by Motion Concepts may adversely affect the radio frequency interference immunity (RFI) levels.
