Section 1

Multimeter Tutorial

The Multimeter

For Powerchairs, the multimeter is one of the most useful tools in the toolbox (fi gure .3.1). It can be used to check wires, shorts, voltages, resistance, and all manner of electrical circuits.

This tutorial is designed to help clarify the symbols and socket options. This Section is meant to be a General tutorial and may not apply to all of the specifi c options on the meter in use. Please consult your user's manual, to avoid errant readings.

The Probes

Probes are found on various multimeters (fi gure

3.2). The Probes connect the meter to the circuit.

Simply touch them to the directed area with the

Mulitmeter on the correct settings, and read the display. Carefully follow instructions for placement of the probes to avoid errant reads.

The Ports

1. The Common Port. (fi gure .3.3)

Generally, the black probe plugs in here

(negative) and as the name suggests, it’s the common element to all of the testing circuits.

Think of it as the ground rail.

2. Voltage, Resistance and Continuity port.

This is a commonly used option. Connect the red (positive) probe to this port when fi nding voltage readings, resistance readings or when checking wire continuity. This is explained in more detail later in the tutorial.

3. Current up to 400mA.

This port is used for “counting electrons” in a circuit, and thus their rate of fl ow (current being the fl ow of electrons). You’ll notice that this side is “fused”, so that you don’t end up melting the meter’s circuits.

4. Current up to 10A.

Same as above, except it can take more current, as the name suggests.

Section 1

Multimeter Symbol Defi nition

AC -

ALTERNATING CURRENT - Use this when you want to test something that has AC current running through it. Typically you'd want to test the voltage of an inverter (for cold cathodes or neons), or a similar device

DC- DIRECT CURRENT. This is the type of electrical power produced by a battery. With a battery connector, the black wire(s) should be connected to the negative(-) terminal of the battery and should be considered the common ground. The red wire(s) should be connected to the positive(+) terminal of the battery and is considered the “hot” lead.

Voltage- This means Voltage or Potential Difference. It will measure the potential difference between the two probes. To measure voltage, connect the positive probe to a port that is marked “V” or Voltage. Note: “mV” means milli-volts = .001 Volt

Current- Since current is measured in Amps and the readout value is in amps, the symbol "A" is used. On this setting the unit measures current that is fl owing through the part of the circuit between the two probes (the meter itself). Typically, you need to plug the positive terminal into a port marked “A” or Current. You need to put the meter “In Series” in the circuit to use this feature correctly.

Resistance- This symbol represents Resistance and is measured in Ohms. You can use this setting to measure the resistance between two points; for example across a piece of wire or a resistor (to check its value). If you don’t have a continuity check, then this can be used to check for shorts. Any value below 0.05

Ohms constitutes a short, meaning that whatever the probes are attached to is connected electrically.

Continuity- A commonly used function. By putting a current through the two terminals (the same as the Ohm-meter function) it can be determined if the resulting value is within the “contact” range, this is signifi ed with a beep. Found on some multimeters, it allows a check for shorts without taking your eyes off your work.

Other meters signify this with a small fl ashing light.

Section 1

Health and Safety

Health and Safety

While working on powered mobility products, it is essential to observe good working practices. Below are a series of safety guidelines and recommendations. Please note that these precautions are intended to serve only as a guide, not to supersede or replace any safety statute, NHS or other safety regulations.

General

• Always wear suitable protective clothing when handling batteries.

• Always wear suitable eye protection when drilling or inspecting.

• When safe to do so, wear protective gloves when handling the running gear or batteries, as these parts are exposed to paths, parks etc.

• If the drive wheels have to be raised off the fl oor, always use a pair of axle stands to secure the vehicle.

Battery Safety

• Use extra caution when working with batteries.

• Always make sure that the batteries are disconnected from the device before commencing work.

• Always check that the battery charger is disconnected from the device

/batteries before commencing work.

• Do not smoke while working on this device.

• Keep batteries away from all sources of ignition.

• Do not place objects on top of the batteries.

• Always keep someone close to your work area so that they may come to your assistance if needed.

• Always wear personal protection when handling batteries, including, eye/face protection and gloves.

• Make sure there is easy access to soap and water in case of acid spills.

• Avoid touching eyes or unprotected parts of the body while working on batteries.

• Remember that non-sealed batteries can contaminate any packaging, housing, or boxes they may have been transported in so handle all packaging with care, especially during disposal.

• If battery acid should come into contact with bare skin or clothing, be sure to wash contacted area immediately, using plenty of soap and water. If battery acid enters the eyes, fl ush with running cold water for as long as possible while medical help is being sought.

• When the tops of batteries are exposed, take extra care when working on or around the terminals.

• Do not allow metal tools to drop on to or touch the exposed terminals of the batteries or other exposed connections, as this could cause a short circuit, which may result in an explosion.


Section 1

Health and safety (cont.)

If mishandled batteries can be dangerous and hazardous.

• All mobility batteries, whether wet type or gel/sealed type, contain lead and sulfuric acid. Both of these materials are toxic and in the case of sulfuric acid, highly corrosive. Additionally, when batteries are charged, they produce hydrogen gas which is “highly” fl ammable and can cause explosion. This is why proper handling is mandatory at all times.

• Battery explosion - This is frequently the result of too low an acid/ electrolyte level in the battery, which allows high concentrations of hydrogen to build up. This is possible with all batteries if improper charging or battery failure occurs, but not common in gel/sealed batteries.

• < KEEP SPARKS AND FLAMES AWAY FROM BATTERIES >

• Burns - dropping a wrench or screwdriver across battery terminals results in sparks, and intense heat. Improper assembly of battery boxes or battery box wiring may short the battery through the wiring and produce a possible electrical fi re.

• Electronic damage - batteries that are improperly wired can short out electronic chair components resulting in expensive repairs.

• Pollution - improper disposal of batteries could damage the environment. All batteries should be disposed of through a reliable battery recycler.

PAGE 1.4


Section 1

Health and Safety (cont.)

• Remove personal items of jewelry, such as rings, watches, chains etc. before working on batteries. Such items could cause short circuits resulting in serious burns.

• Batteries are constructed of heavy materials. Therefore moving batteries requires appropriate lifting techniques. Safety footwear should also be worn. In addition, disposal of old batteries requires compliance to state laws. Contact your local authority for their recommendations.

Battery Chargers

• Remember battery chargers are connected to household current.

• Always observe all guidelines and laws relating to electrical equipment.

• Never operate the battery charger in wet or damp conditions.

• If you think that the charger has been exposed to water or excessive dampness, do not use it. Return the unit to the dealer/supplier for inspection/replacement.

• If you think the battery charger is defective or is visibly damaged, return the unit to the dealer/supplier for inspection.

EMI Warnings

• EMI means electromagnetic (EM) interference (I). EMI comes from radio wave sources, such as radio transmitters and transceivers. A

“transceiver” is a device that both sends and receives radio wave signals.)

• There are a number of sources of intense EMI in our daily environment. Some of these are obvious and easy to avoid. Others are not, and the user may not be able to avoid them.

• Powered wheelchairs, although tested in accordance with EMC guidelines, may be susceptible to electromagnetic interference (EMI) emitted from sources such as, radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios, and cellular phones.

• EMI can also be produced by conducted sources or electro-static discharge (ESD).

What effect can EMI have?

1. EMI can, without warning, can cause a power chair to:

• Release its electronic brakes

• Move by itself

• Move in unintended directions.

If any of these occur, severe injury could result.

2. EMI can damage the control system of a power chair, resulting in a safety hazard and/or costly repairs.


Section 1

Sources of EMI

1. Hand-Held Transceivers: Antenna is usually mounted directly on the unit.

These include:

• Citizens band (CB) radios

• “Walkie-talkies”

• Security, fi re and police radios

• Cellular phones

• Lap top computers with phone or fax

• Other personal communication devices

Note - These devices can transmit signals while they are on, even if not in use.

The wheelchair should be switched off when not in use.

2. Medium-Range Mobile Transceivers: include two-way radios used in police cars, fi re engines, ambulances and taxi cabs. The antenna is usually mounted on the outside of the vehicle.

3. Long-Range Transceivers: These include commercial radio and TV broadcast antenna towers, amateur (HAM) radios, and alarm systems.

NOTE- The following are Not likely to cause EMI problems: Lap-top computers

(without phone or fax), cordless phones, TV sets or AM/FM radios, CD or tape players.

EM energy rapidly becomes more intense as you get closer to the source. For this reason, EMI from handheld devices is of special concern. A person using one of these devices can bring high levels of EM energy very close to a power chair without the user’s knowledge.

Immunity level

The level of EM is measured in volts per metre (V/m). Every power wheelchair can resist EMI up to a certain level. This is called its “immunity level”. The higher the immunity level, the less the risk of EMI. It is believed that a 20 V/m immunity level will protect the power wheelchair user from the more common sources of radio waves.

For the QM-710, the confi guration tested and found to be immune to at least 20

V/m is: a right-handed mounted joystick system, 18” seat width, 18” seat depth, dual-post height-adjustable armrests, fi xed tapered legrests with one-piece solid footplate and Gp 24 gel cell batteries.

The following dealer installed speciality input devices have an unknown effect on the immunity level because they have not been tested with the Quickie control systems:

• Breath Control (“Sip n Puff”)

• Tri-Switch Head Array

• Proximity Head Array

• Proportional Mini-Joystick/Chin Control

• Buddy Button

• Wafer Board

PAGE 1.6


Section 1

Cautions for circuit boards

To help prevent Electro Static Discharge (ESD) the following proper handling techniques should be followed:

ESD:

• Do not place Printed Circuit Boards or their containers near sources of strong electrical fi elds (such as above a CRT).

• To avoid the occurrence of static charge or discharge due to friction, keep the Printed Circuit Boards separate from one another and do not stack them directly on top of one another if not protected by antistatic bags.

• Store each Printed Circuit Board in an antistatic bag with an external cushioning bubble-wrap layer until assembled to wheelchair. Antistatic bag must have metal content to protect the printed circuit board. Gray bag protects from ESD, pink bag or bubble wrap does not protect as well.

• Always wear an ESD preventive wrist or ankle strap when handling electronic components. Connect one end of the strap to an ESD jack or an unpainted metal component on the system

(such as a captive installation screw).

• Handle Printed Circuit Boards by the edges only; avoid touching the Printed Circuit Board and connector pins.

• Place any removed Printed Circuit Board on an antistatic surface or in a static shielding bag.

• Avoid contact between the Printed Circuit Boards and clothing.

The wrist strap only protects the card from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Make sure that the Printed Circuit Board power is off by disconnecting the seating harness prior to attaching or removing printed circuit board.

Printed Circuit Board Flexing:

• The printed circuit board has surface-mount components that may break when the board is fl exed. To minimize the amount of board fl exing, observe the following precautions:

• Hold the printed circuit board only by the edges.

• Do not place the printed circuit board on a hard surface.

• Tighten board mounting screws only hand tight (torque12.4 in lbs/1.4Nm) in a cross pattern to reduce stress on mounting holes and PCB board material.


Section 1

Battery Types

IT IS THE RESPONSIBILITY OF THE INSTALLER TO KNOW WHAT KIND OF BATTERIES TO

INSTALL IN A CUSTOMER’S WHEELCHAIR!

• Deep-cycle batteries used in wheelchairs are designed to be discharged and recharged on a regular basis.

• Starting or automotive type batteries use a rapid burst of power to start an engine and are quickly recharged by an alternator or generator. They are rated by cold cranking amps, a measure that has no relevance to wheelchair application.

• Marine and RV batteries frequently are not deep-cycle as they are often used for starting engines.

• Only use Deep-Cycle sealed type batteries in a wheelchair.

Battery Size

• Batteries function as a power wheelchair’s fuel tank. The larger the group size, the farther the wheelchair will go.

• Use the size specifi ed by the wheelchair manufacturer. Never use undersized batteries

• This chair uses either 22NF, or GRP 24

Batteries. Flat-top batteries help lower the seat to fl oor height.

QM-7 SERIES SERVICE MANUAL SUNRISE MEDICAL

Section 3

VR2 Troubleshooting

No power: Battery Diagnostics

Note: For access to batteries, refer to beginning of Section 7 (Battery Access/ removal)

Battery Servicing and Replacement

Batteries should last an average of 1 to 1.5 years.

Listed below are some Factors that may effect battery performance:

• Maintenance - Poor maintenance.

• Charging - Improper charging shortens battery life.

• Chair Components - Malfunctioning electronics, bad motors, electric brakes, and

corroded wiring are also capable of degrading the battery performance.

A routine test of deep-cycle wheelchair batteries should follow these guidelines:

1. Never replace just one battery at a time. This will create an imbalance when charging and ultimately damage both batteries.

2. Check batteries for a voltage difference. A voltage difference of more than .4 volts D.C. is a good indicator of a bad battery.

3. Voltage test - A dead battery cannot be effectively tested, yet many people mistakenly try to do just that. Any battery that reads 11.0 volts or less is technically dead.

To perform any testing, especially a load test:

A. Batteries must be charged

B. The top charge must be taken from fully charged batteries if charge rate has just fi nished.

Battery Tests

• Load Test - This test can only be done on fully charged batteries and can only diagnose one type of problem, (an internal short.)

• Capacity/Discharge Test - This is the only accurate way to test a deep-cycle battery for adequate running time. The problem with this test is that it is time consuming.

• Current / Voltage check with a regular interval check - Another way of truly knowing how much time your battery will last, but it is also time consuming.

Note: The voltmeters on load testers are not accurate enough to establish a state of charge.


Section 3

Battery Connection Test

1. Check that the female VR2 Bus plug on the chair has voltage. Set the meter to DC volts and measure pins 4 (using the red lead of the meter) and 1 (using the black lead of the meter) as shown in (fig 3.2.1)

Fig 3.2.1

2. If the voltage meter reads full voltage, then replace the joystick module

If the voltage meter reads zero voltage, measure the corresponding pins on the VR2 controller as shown in (fig 3.2.2).

If the voltage meter reads full voltage, then replace the jumper cable. If the voltage meter reads zero, then measure the Battery Connector as shown in (fig 3.2.3). If the voltage meter reads full voltage, replace the controller, or proceed to the next step.

Fig 3.2.2

Fig 3.2.3


Check Battery Wire Harness

1. Check that the battery wire harness has the correct polarity. Set the meter to dc volts and measure the connector with the red lead on the positive terminal, and the black lead on the negative terminal as shown in (figure 3.2.4). If the voltage is absent Replace the Main Battery wire

Harness. If the polarity is reversed correct battery wiring.

The Maximum Speed Indicator Ripples

How to Lock or Unlock the Wheelchair

Maximum Speed Indicator Ripples. This Indicates that the wheelchair is locked. To unlock the wheelchair, deflect the joystick forwards until the control system chirps. Then deflect the joystick in reverse until the control system chirps. Release the joystick, there will be a long beep. The wheelchair is now unlocked. To lock the wheelchair, while the control system is switched on, depress and hold the on/off button. After 1 second, the control system will chirp. Now release the on/off button, deflect the joystick forwards until the control system chirps, and deflect the joystick in reverse until the control system chirps. Release the joystick, there will be a long beep. The wheelchair is now locked.

The Maximum Speed Indicator Flashes

This indicates that the chair is charging . The chair will be ready to drive as soon as the charger is unplugged.

Battery Gauge is Steady

This indicates that all is well.

Battery Gauge Flashes Slowly

The control system is functioning correctly, but you should charge the battery as soon as possible. At

22 V, the red light starts to blink. Each bar represents a .5V value. The controller requires 18V to start and a minimum of 16V to work once started

Battery Gauge Steps Up.

Indicates the wheelchair batteries are being charged with the offboard charger. You will not be able to drive the wheelchair until the charger is disconnected and you have reset the control system by switching off the power and then powering up again.

Battery Gauge Blinks Every 2.5 Seconds

The control system has "gone to sleep" because the wheelchair has not been driven for a period of time. The time period depends on the programming of the system. To re-start, reset the system by switching off the power and then powering up again.

Battery Gauge Flashes Rapidly

Make sure the Joystick is completely released (Joystick should be centered and/or nothing is pushing the gimbale out of center). The control system safety circuits have been activated and the control system has been prevented from moving the wheelchair. This indicates a system trip, i.e. the VR2 has detected a problem somewhere in the wheelchair's electrical system. Please refer to this Section

(VR2 Controller Diagnostics).


Section 3

Troubleshooting with VR2 Diagnostic Codes

One Bar - Low Battery Voltage

This code could indicate discharged batteries, failed batteries, or poor battery connections.

Begin by recharging the batteries and then refer to 3.2 to check batteries and connections.

Two Bars - Left Motor Disconnected

1. Check that the batteries are fully charged and in good condition. Check all cables and connections. Check the connections to the left motor, look for a loose or damaged connector.

2. Otherwise, check the brushes on the left motor Using a Flat head screwdriver (figure

3.4.1) remove the brush cap to access the brush

(figure 3.4.2). Refer to section 6 (Motor Brush

Inspection). Ensure brush is not excessively worn, (brush need to be at least 1/2" long) note taper (figure 3.4.3) on brush for re-installation

3. Use the meter to check the resistance across the two bottom contacts (thicker wires) on the

4-pin motor connector as shown in (figure 3.4.5).

If the meter reads between 0 to 1.5 ohms, then replace the controller. If none of the above corrects the problem, replace the left motor.

Fig 3.4.5

Three Bars - Left Motor Wiring Trip

1. Check that the batteries are fully charged and in good condition; and check all cables and connections. Check the connections to the left motor, look for a loose or damaged connector.

2. Measure the resistance from the bottom contact of the red thick wire on the 4-pin left motor connector to each of the top contacts of the connector (figure 3.5.1). Measure the resistance from the bottom contact of the black thick wire on the 4-pin left motor connector to each of the top contacts of the connector (figure 3.5.2). If all of the readings are open, then replace the controller.

If any of the readings are short, then replace the left motor.

Section 3

Six Bars - Charger Connected

The onboard batteries are being charged with the off-board charger. You will not be able to drive the wheelchar until the charger is disconnected. You will have to reset the control system by switching off the power and then powering up again. The On-Board charger has no indication that the chair is charging, and the chair will not move until complete. If the condition still exists after the charger has been diconnected, and the chair has been switched off and then powered up again, the Joystick module may be defective.

Seven Bars - Possible Joystick Trip

A joystick trip is indicated. Make sure that the joystick is in the center position before switching on the control system. Check that the batteries are fully charged and in good condition, examine the joystick for damage. This fault can also be caused by a joystick that fails to center itself due to being dirty, bent or broken. If this is the case, replace the joystick module.

Note: If replacing the joystick does not resolve the issue, replace the cable connecting the joystick to the controller.

Seven Bars + Speed Profile Indicator error

Inspect the wiring between joystick module and controller. Replace a jumper or joystick module that has damaged wiring. If the problem persists replace the controller.

Eight Bars - Possible Control System Trip

Controller Fault - A control system trip is indicated. Make sure that all connections are secure. Check that the batteries are fully charged and in good condition, and check all joystick connections and cables. If this does not correct the problem,disconnect the power to the controller for 2 minutes, replug in to reboot the module. If the condition still exits, then replace the controller.


Section 3

Nine Bars - Solenoid Brake Trip

The parking brakes have a bad connection.

Make sure that the motor is in the locked/ engaged position. Check the parking break and motor connections. Make sure the control system connections are secure. Measure the two small contacts on the four-pin motor connector (figure

3.8.1).

(figure 3.8.2) shows Motor in locked (Drive) position, for Testing in Nine bar state.

Fig 3.8.1

fig. 3.8.2

Ten Bars - High Battery Voltage

An excessive voltage has been applied to the control system. This is usually caused by a poor battery connection. Check the battery connections.

Battery Fault

Check that the batteries are fully charged, at the correct voltage, and in good condition. Take a voltage reading from pin 1 and pin 2 of the charger port of the VR2 controller, see (figure 3.8.3) If the meter reads more than 30 volts, then check the charger. Otherwise, replace your controller.

Power Chair Will Not Drive Full Speed

An external micro-switch is mounted next to the actuator in the rear of the lift system. This microswitch is closed when the tilt is lowered. The closing of this micro-switch sends a signal to the control module through the 6-pin connector located on the back of the tilt. The presence of this signal informs the control module that the tilt is less than 20 degrees and that maximum speed should be used. If the tilt is more than 20 degrees, the switch opens and invokes “creep” speed. Creep speed is a predetermined speed programmed at time of manufacture. Creep is indicated by a “turtle” on either the hand control or Omni.

1. “Creep” speed as indicated by the turtle on the hand control (A) fi gure 4.7.2). If the turtle symbol persists after a power down, proceed to step 2.

Chair Won't Drive in Creep Speed When Tilted

An external micro-switch is mounted next to the actuator in the rear of the lift system. This micro-switch is closed when the tilt is lowered. When micro-switch is closed, it sends a signal from the control module through the 6-pin connector. The presence of this signal informs the control module that the tilt is less than 20 degrees and that maximum speed can be used. If the tilt is more than 20 degrees, the switche opens and invokes “creep” speed. Creep speed is a predetermined speed programmed at time of manufacture. Creep is indicated by a “turtle” on either the hand control or Omni.

1. Tilt the seat all the way back and observe the hand control or Omni to see if the turtle symbol

b. Use Multimeter and measure continuity between the indicated pins (fi gure 4.10.1) on the 6-pin connector mounted on the tilt. When seat is tilted the indication should be open (fi gure 4.10.2). c. If it is closed, check parts manual for availability of the micro-switch assembly. Refer to Micro-

Switch Removal, and Tilt Actuator removal subsections in section 7 of this manual. d. Retest as necessary.

Tilt/Lift Will Not Operate

The tilt actuator used in the tilt system receives power through a 6-pin connector located at the rear of the tilt See "B" (Figure 4.8.2). The actuator also contains micro-switches that open at the end of their stroke to prevent stressing of the tilt system. Around these micro switches are diodes that allow reverse power to fl ow to the actuator when reversing direction.

1. Select tilt on the hand control (fi gure. 4.10.3).

Operate the joystick and listen closely to the control module for a click. This click indicates that the control module is closing the power relay inside and supplying power to the tilt actuator.

If no click is heard, replace the control module.

Refer to Control Module Removal in section 7 of this manual. Retest as necessary. If click is heard proceed to step 3.

2. Verify that tilt is selected on the hand control.

Operate the joystick and listen closely to the tilt actuator. If the actuator appears to be running but the tilt is not moving, replace the tilt actuator. Refer to Micro-Switch Removal and Tilt Actuator removal section of this manual. Retest as necessary.

3. If tilt will still not operate, locate the 6-pin connector on the rear of the tilt See "B"

(fi gure 4.8.2).

Battery Testing

Note: The QM-710 power chair uses either (2) 22NF, or GRP 24 batteries connected in series.

The circuit is protected by a non-serviceable fusible link in each battery harness. Prior to performing any test, the battery terminals should be clean and tight. For Access to the

Batteries, Refer to Section 7: Battery Access/Removal.

1. Check for initial battery voltage at the joystick using the battery charger connector. Connect the

Multimeter to the two outside pins (fi gure 5.1.1).

Pin 1 is positive (+) and pin 2 is negative (-). Fully charged batteries are typically 25.6 VDC for the pair, or 12.8 VDC each. Discharged batteries are

24 VDC or less for the pair.

2. Load test the batteries using either a commercial load tester or the following procedure. fig. 5.1.1

Note: Voltage greater than 26 to 28 VDC indicates the batteries are either over-charged, or have just been disconnected from the battery charger, and contain a surface charge. If the batteries are not freshly charged and voltage is excessive, inspect battery charger.

Warning: Failure to disengage the gearbox in the next step can cause unexpected operation of the power chair.

To use the power chair’s motors as a load tester, complete the following steps: a. Disengage the motor/gearbox so the motors can run in freewheel (fi gure. 5.1.2).

b. Connect the Multimeter to the joystick and record the voltage (fi gure. 5.1.3). If the voltage indicates a surface charge, run the motors for a few minutes to dissipate the surface charge.

Note: in this example, a small surface charge is present.

c. After the voltage has stabilized, record the voltage. Typical value for a fully charged pair of batteries is 25.6 VDC (12.8 VDC each).


QM-7 SERIES SERVICE MANUAL JANUARY 2012 fig. 5.1.3

PAGE 5.1

Section 5 d. Operate the power chair at high speed by operating the joystick in a high-speed profi le. The motors should put approximately a 5 to 10 amp load on the batteries. e. Continue to operate the motors for 60 seconds.

Record the readings and compare them to the following: i. During the fi rst 5 seconds, normal voltage drop should be approximately .5 to .6 VDC.

ii. During the remaining portion of the 60 seconds, the voltage should stabilize, dropping no more than an additional .1 to .2 VDC. iii. At the end of the 60 seconds, release the joystick. f. At the end of a 5 minute rest, note the voltage recorded on the Multimeter. Normal indication at the end of a 5 minute rest is typically the starting voltage, or no more than .1 VDC less. fig. 5.2.1

Notes:

• A rapid drop of approximately 1.5 or more during the fi rst 5 seconds indicates a shorted cell in one or both of the batteries. The battery terminals should be checked to ensure that they are tight and clean, and then the test should be repeated. If the terminals are tight, the batteries should be replaced. Refer to Battery Removal section of this manual.

• A slow drop of more than .8 volts during the fi rst few seconds indicates a weakened pair of batteries. Evaluate the age of the batteries and the use they have received, and consider replacing them.

• If the voltage does not return to .1 VDC of the starting voltage at the end of the 5 minute test, evaluate the age of the batteries and the use they have received, and consider replacing them.

PAGE 5.2


Section 5

3. The individual voltage of each battery may also be checked using a Multimeter. Connect the

Multimeter to the battery connector (fi gure 5.3.1).

Note: Refer to Battery Removal (Section 7).

Compare the values to the following. a. 12.8 VDC indicates a fully charged battery. b. The battery readings should be similar. Newer batteries typically read within .1 to .2 VDC. c. 13 VDC or more indicates an overcharged battery, or one that has a surface charge from being recently removed from the charger. Verify correct operation of the battery charger if the batteries have not recently been removed from charge. d. 11.9 to 12 VDC indicates a discharged battery.

Recharge as necessary. e. Less than 11.9 VDC indicates an excessively discharged battery. f. Values larger than 13 VDC indicate either an overcharged battery or one that has just been removed from charge, as in the example (fi gure

5.1.1) fig. 5.3.1

Adjustment procedures

Seat/Back Width adjustment

Note: The same procedure is used for the 18" - 22" wide seating system

ASAP II Seating 16” - 20” wide is shown.

The ASAP II seating system is fully adjustable to allow changes from 16” to 20” or 18” – 22”.

This requires a frame weldment and seat pan plates adjust for seat growth. The picture shown in (figure 8.1.1) has a seat width of 20” . This detail shows how easy it is to change back to

16” wide.

VR2/R-Net Control

The actuator buttons can operate any factory approved actuator. Operation is dependent on what options are fitted to your wheelchair. To operate the legrests, seat tilt, seat lift or back rest recline follow the following steps

1. For VR2, Push one of the actuator buttons that has the seat icon on it to select actuator mode

2. Operate the joystick in the forward or rearward direction to move the desired actuator up or down.

3. Release the joystick when the desired angle is reached.

4. To return to drive mode press the actuator button again or Mode for R-Net.

The Multi Axis box

(figure 9.2.1) has 3 settings available – with

Toggling occurring in each of these settings. On this example below hitting the blue will cause combined legrest to extend – hitting yellow button will extend left mounted actuator and orange for right mounted actuator. Simply touch the switch for Right Leg and the leg will either extend outward or retract inward – once fully extended or retracted it is recommended to let go of switch.

(figure 9.2.2) shows all connectors to actuator are 6 pin molex connectors. The lead (A) going back for power connects to the control module as shown below via OBCport (figure 9.2.3)

The test for power can be done quite simply by removing connector from actuator and hooking up Multi meter to pins shown. (figure 9.2.4) connection prior to depression of switch.

(figure 9.2.5) shows depression switch and what meter will read.
