GENERAL GUIDELINESPROCEDURE 1

E N E R A L

Repair or Service Information Operating Information

REPAIR OR SERVICE INFORMATION Set-up of the Electronic Control Unit is to be performed ONLY by individuals certified by Invacare. The final tuning adjustments of the controller may affect other activities of

I D E L

I N E S

the wheelchair. Damage to the equipment could occur under these circumstances. If non-certified individuals perform any work on these units, the warranty is void.

OPERATING INFORMATION

GENERAL WARNINGS

Performance adjustments should only be made by professionals of the healthcare field or persons fully conversant with this process and the driver's capabilities. Incorrect settings could cause injury to the driver, bystanders, damage to the chair and to surrounding property.

After the wheelchair has been set-up, check to make sure that the wheelchair performs to the specifications entered during the set-up procedure. If the wheelchair does NOT perform to specifications, turn the wheelchair OFF immediately and reenter set-up specifications. Repeat this procedure until the wheelchair performs to specifications.

DO NOT use parts, accessories, or adapters other than those authorized by Invacare.

TIRE PRESSURE DO NOT use your wheelchair unless it has the proper tire pressure (P.S.I.). DO NOT overin-

flate the tires. Failure to follow these suggestions may cause the tire to explode and cause bodily harm. The recommended tire pressure is listed on the side wall of the tire.

ELECTRICAL Grounding Instructions:

DO NOT, under any circumstances, cut or remove the round grounding prong from any plug used with or for Invacare products. Some devices are equipped with three-prong (grounding) plugs for protection against possible shock hazards. Where a two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to contact a qualified electrician and have the two-prong receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the National Electrical Code. If you must use an extension cord, use ONLY a three-wire extension cord having the same or higher electrical rating as the device being connected. In addition, Invacare has placed RED/ORANGE WARNING TAGS on some equipment. DO NOT remove these tags.

BATTERIES The warranty and performance specifications contained in this manual are based on

the use of deep cycle gel cell or sealed lead acid batteries. Invacare strongly recommends their use as the power source for this unit.

TROUBLESHOOTING PROCEDURE 2

This Procedure Includes the Following: Field Load Test Using Hydrometer To Check Battery Cells (Lead

Acid) Motor Testing Motor Brush Inspection Electro-Mechanical Parking Brake Test

FIELD LOAD TEST (FIGURE 1)

NOTE: The following test can also be performed through the controller of the wheelchair along with a remote programmer. Refer to the individual CONTROLLER MANUAL supplied with each wheelchair.

Old batteries lose their ability to store and release power, due to increased internal resistance. This means that as you try to take power from the battery, some of that power is used up in the process of passing through the battery, resulting in less voltage at the posts. The more power drawn, the lower the voltage available. When this lost voltage drops the output 1.0 volts under load (2.0 for a pair), replace the batteries.

Testing under load is the only way to spot this problem. While special battery load testing equipment is available, it is costly and difficult to transport.

Use a digital voltmeter to check battery charge level at the charger connector. It is located on the base of the wheelchair frame.

NOTE: READ the instructions CAREFULLY before using the digital voltmeter.

NOTE: Invacare recommends that ONL Y qualified service personnel perform this test.

1. Ensure that power is OFF.

2. Make sure battery is fully charged. An extremely discharged battery will exhibit the same symptoms as a bad one.

3. Place a one (1) piece of wood taller than the axle of the drive wheels between the wheelchair and a wall, workbench or other stationary object.

4. Remove the footrests from the wheelchair and place the stabilizer wheels or the front of the wheelchair against the piece of wood.

5. Place the voltmeter leads into the charger plug on the wheelchair. Most digital voltmeters are not affected by polarity, however, analog meters (meters with swinging needles) can be and should be used carefully. A good meter reading should be 25.5 to 26 VDC.

6. Have two (2) individuals (one [1] on each arm) apply as much downward pressure as possible on the arms of the wheelchair.

7. Turn the wheelchair ON and push the joystick forward, trying to drive the wheelchair through the stationary object. This puts a heavy load on the batteries as they try to push through the stationary object. Read the meter while the motors are straining to determine the voltage under load.

NOTE: If the voltage drops to less than 23.5 volts from a pair of fully charged batteries while under load, they should be replaced regardless of the unloaded voltages.

USING HYDROMETER TO CHECK BATTERY CELLS (LEAD ACID) (FIGURE 2)

NOTE: Perform this procedure when a digital voltmeter is not available.

WARNING

NEVER smoke or strike a match near the batteries. If the caps of the battery cells are removed, NEVER look directly into them when charging the battery.

The use of rubber gloves and safety glasses is recommended when testing the battery cells.

When reading a hydrometer, DO NOT allow any liquid to come in contact with your eyes or skin. It is a form of acid and can cause serious burns, and in some cases, blindness. If you do get battery acid on you, flush the exposed areas with cool water IMMEDIATELY. If the acid comes into contact with eyes or causes serious burns, get medical help IMMEDIATELY.

The battery acid can damage your wheelchair, clothing, and household items. Therefore, take readings cautiously and only in designated areas.

properly read. A shorted or dead cell can be detected when it is the only cell that does not charge.

9. Flush hydrometer in cold running water by allowing the water to rise into hydrometer as far as possible. Do this several times to guard against burn damage.

10. Replace the battery caps.

11. Reinstall battery boxes. Refer to one (1) of the following: A. FWD WHEELCHAIRS:

MOTOR TESTING (FIGURE 3)

1. On the 4-pin motor connector, locate the two (2) contacts in the red and black housings.

NOTE: DO NOT fill hydrometer more than 3/4 full.

5. Draw up sufficient acid to cover float balls.

6. Tap lightly to remove air bubbles.

7. Number of floating balls indicates charge.

Number of Floating Balls

2. Set the digital multimeter to measure ohms (Ω).

3. Measure the resistance between the two (2) motor contacts.

NOTE: A normal reading is between 1 and 5 ohms (Ω). A reading of 0 ohms (Ω) or in excess of 15 ohms (Ω) indicates a problem. High readings are generally caused by bad connections and/or damaged brushes. Contact authorized dealer or Invacare.

FIGURE 3 - MOTOR TESTING

TROUBLESHOOTING PROCEDURE 2

MOTOR BRUSH INSPECTION (FIGURE 4)

There are two (2) contact brushes on the motors located under the brush caps on the motor housing. If these caps are hard to remove they are either overtightened or the motor has become very hot. Let motors cool. If caps still cannot be removed, it is recommended that the motor be sent to Invacare Technical Services for inspection/repair.

NOTE: It is very important to note which way the brush comes out of the motor. The brush MUST be placed into the motor exactly the same way to ensure good contact with the commutator.

1. Once the motor brush caps have been removed, pull the brushes out of the motor. The end of the brushes should be smooth and shiny and the spring should not be damaged or discolored. If one or both of the brushes are damaged, only the damaged or worn brushes need be replaced. It is very important that any time a brush is replaced, it must be “burned in”. This is accomplished by running the motor for one hour in each direction with a half hour break in-between. This should also be done with little or no load on the motor, i.e., put the wheelchair up on blocks so the drive (large) wheels do not contact the ground and run the wheelchair. A motor with only one brush replaced will only carry a small percentage of its rated load capacity until the NEW brush is burned in.

ELECTRO-MECHANICAL PARKING BRAKE TEST (FIGURE 5)

1. On the four-pin motor connector, locate the side by side connectors in the black housings.

2. Set the digital multimeter to read ohms (Ω).

3. Measure the resistance between the two (2) brake contacts. A normal reading is 100 ohms (Ω). A reading of 0 ohms (W) or a very high reading; i.e., MEG ohms or O.L. (out of limit) indicates a shorted brake or an open connection respectively. If either condition exists, send the motor to Invacare Technical Service for inspection/repair.

CAUTION

A shorted electro-mechanical brake will damage the brake output section in the controller. DO NOT connect a shorted electro-mechanical brake to a good controller module. A shorted brake MUST be replaced.

NOTE: A bad motor can damage the controller module but a bad controller should NOT damage a motor.

WHEN TO CHARGE BATTERIES (FIGURE 17)

It is advantageous to recharge frequently rather than only when necessary. In fact, a battery’s life is extended if the charge level is maintained well above a low condition.

BA TTERY DISCHARGE INDICA TOR (BDI) is located at the rear of the joystick housing and provides information on the remaining charge in the batteries. At FULL charge the BDI will be GREEN. As the battery becomes discharged, the BDI indicator will turn AMBER (YELLOW), then RED and finally FLASHING RED. If the BDI is FLASHING RED, the user should charge the batteries as soon as possible.

NOTE: Accurate readings are displayed when in neutral.

Battery Discharge

Indicator

Description and Use of Battery Chargers

The charger automatically reduces the charge from an initially high rate to a zero reading at a fully charged condition. If left unattended, the charger should automatically shut-off when full charge is obtained.

There are some basic concepts which will help you understand this automatic process:

The amount of electrical current drawn within a given time to charge a battery is called “charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is high, as indicated by the green light on the charger. Initially, the green light will stay illuminated for a short period of time followed by a longer period of off time. As a charge builds up, the charge rate is reduced, and the green light will stay illuminated for a longer period of time followed by a shorter off time.

NOTE: If performing the charging procedures independently, READ and CAREFULLY follow the individual instructions for each charger (supplied or purchased).

NOTE: If charging instructions are not supplied, consult a qualified service technician for proper procedures.

Required Items:

FIGURE 17 - WHEN TO CHARGE BA TTERIES

CHARGING BATTERIES (FIGURE 18)

WARNING

Never attempt to recharge the batteries by attaching cables directly to the battery terminals or clamps. Always use the recharging plug located on the side of the wheelchair frame.

DO NOT attempt to recharge the batteries and operate the power wheelchair at the same time.

During use and charging, unsealed batteries will vent hydrogen gas which is explosive in the right concentration with air.

CAUTION

Always charge new batteries fully BEFORE initial use or battery life will be reduced.

NOTE: As a general rule, batteries should be recharged daily to assure the longest possible life and minimize the required charging time. Plan to recharge the batteries when it is anticipated the wheelchair will not be used for a long period of time.

The range per battery charge using recommended batteries should be approximately 5 to 9 hours of typical operation. Extensive use on inclines may substantially reduce per charge mileage.

TOOL QUANTITY COMMENTS

Battery Charger 1 Supplied

✪ 3-prong plug, 15 ampere current rating; industrial type

1. If necessary, remove the rear shroud. Refer to

REMOVING/INSTALLING SHROUDS in this

procedure of the manual.

2. Attach the battery charger connector to the charger cable/battery harness.

3. Plug the charger’s AC power cord, or extension, into the grounded 120 VAC wall outlet.

4. Wait until charging is complete.

NOTE: Allow eight (8) hours for normal charging. Larger batteries (greater than 55 ampere-hours) or severely discharged batteries may require up to sixteen (16) hours to be properly charged and equalized. If the charger operates for sixteen (16) hours and is unable to fully charge the batteries, an internal timer turns the charger off and begins to fast blink the green light.

NOTE: If the batteries need to be charged more often or take longer to charge than normal, they may need to be replaced. Contact an authorized dealer for service.

5. If necessary, install the rear shroud. Refer to REMOVING/INSTALLING SHROUDS in this proce- dure of the manual.

WARNING

Most batteries are not sold with instructions. However, warnings are frequently noted on the cell caps. Read them carefully, otherwise injury or damage can occur.

NOTE: Invacare recommends that both batteries be replaced if one (1) battery is defective.

Recommended Battery Types

WARNING

The warranty and performance specifications contained in this manual are based on the use of deep cycle gel cell or sealed lead acid batteries. Invacare strongly recommends their use as the power source for this unit.

CAUTION

Failure to use the correct battery size and/or voltage may cause damage to your wheelchair and give you unsatisfactory performance.

Cleaning Battery Terminals

WARNING

DO NOT allow the liquid in the battery to come in contact with skin, clothes or other possessions. It is a form of acid and harmful or damaging burns may result. Should the liquid touch your skin, wash the area immediately and thoroughly with cool water. In serious cases or if eye contact is made, seek medical attention IMMEDIA TELY.

NEVER smoke or strike a match near batteries. If the caps of the battery cells are removed, NEVER look directly into them while charging batteries.

1. Examine battery clamps and terminals for corrosion.

2. Verify that the plastic caps are in place over the battery cell holes.

3. Clean the terminals and inside the battery clamps by using a battery cleaning tool, wire brush, or medium grade sand paper.

NOTE: When done, these areas should be shiny, not dull.

4. Carefully dust off all metal particles.

PROCEDURE 9RWD WHEELCHAIRS

WHEN TO CHARGE BATTERIES (FIGURE 4)

NOTE: As a general rule, batteries should be recharged daily to assure the longest possible life and minimize the required charging time. In fact, a battery’s life is extended if the charge level is maintained well above a low condition. Plan to recharge the batteries when it is anticipated the wheelchair will not be used for a long period of time.

BATTERY DISCHARGE INDICATOR (BDI) is located at the rear of the joystick housing and provides information on the remaining charge in the batteries. At FULL charge the BDI will be GREEN. As the battery becomes discharged, the BDI indicator will turn AMBER (YELLOW), then RED and finally FLASHING RED. If the BDI is FLASHING RED, the user should charge the batteries as soon as possible.

Battery Discharge Indicator

NOTE: Accurate readings are displayed when in neutral.

FIGURE 4 - WHEN TO CHARGE BA TTERIES

CHARGING BATTERIES (FIGURE 5)

NOTE: New batteries MUST be fully charged prior to initial use of the wheelchair.

WARNING

Never attempt to recharge the batteries by attaching cables directly to the battery terminals or clamps. Always use the recharging plug located on the side of the wheelchair frame.

DO NOT attempt to recharge the batteries and operate the power wheelchair at the same time.

During use and charging, unsealed batteries will vent hydrogen gas which is explosive in the right concentration with air.

CAUTION

Always charge new batteries before initial use or battery life will be reduced.

Range per battery charge using recommended batteries should be approximately 5 to 9 hours of typical operation. Extensive use on inclines may substantially reduce per charge mileage.

Description and Use of Battery Chargers

There are some basic concepts which will help you understand this automatic process:

NOTE: If performing the charging procedures independently, READ and CAREFULLY follow the individual instructions for each charger (supplied or purchased).

NOTE: If charging instructions are not supplied, consult a qualified service technician for proper procedures.

Required Items:
