- Batteries
Description: The batteries are used to power the chair and need to be maintained to have full potential and use of product. Please use specified batteries and follow all charging recommendations. Please use charger provided by manufacturer – neglect of this will void warranties.
Safety
If mishandled batteries can be dangerous and hazardous.
1. All mobility batteries whether Gel or 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”
flammable and can cause a possible explosion. This is why proper handling is mandatory at all times.
2. Battery explosion - this is the result of too low an acid/electrolyte level in the battery, which allows high concentrations of hydrogen to built up. This is possible with all batteries if improper charging or battery failure occurs. But not common in gel/sealed batteries.
3. Keep sparks and flames away from batteries
5
4. Burns – dropping a wrench or screwdriver across battery terminals results in sparks and arcing and intense heat. Improper wiring and assembly may short the battery the wiring and produce an electrical fire.
5. Pollution – Batteries should be disposed at a reliable battery recycler. Improper disposal of batteries damage the environment.
Battery Charger Cycle Illustration Typical flooded battery
As battery discharges, the sulfate from the electrolyte forms on the plates. As battery recharges, the sulfate is driven back into the electrolyte.

Troubleshooting Batteries
1. Check for good voltage at Module input charger port. Should read between 23.5 and 25.8 volts for proper operation. Less than 23.5 volts will give a low battery Indicator (2 Bar flash).
2. If no voltage at port go to cable that inputs voltage to Control found on battery box connector shown earlier. Once again verify voltage and check for popped circuit Breaker. Reset Circuit breaker.
3. If still no power go directly to individual batteries across + and – posts to see at least 12.2 to 13 volts (fully charged).
4. The 3 tests above will verify voltage in what is known as an unloaded state. The next test is to insure batteries last under load. This can be done a number of ways. 2 ways of checking are listed below: a) The load test across the + and – terminals of battery - make sure battery is in full charged state. Hook up load tester and draw 100 amp load across for 10 seconds. b) The chair has a free wheel release where the motor and gearbox can be run un-loaded – this still draws 3 -4 amps across the load. Hold joystick or input device for 1 minute If after release in a minutes time it drops more than a volt Change batteries – if it drops between .6 and 1 volt it has a Cell that is weak and batteries will no stay fully charged It is recommended to change batteries. If the voltage after a minutes time drop less that .1 volt but not greater than
0.5 volts the batteries are in good shape.
Code 2C00 – indicates Low Battery - 1 Bar Flashing

Chargers
Introduction: The battery charger is another essential part of the Power Chair for the batteries need to be fully charged daily for heavy users. It is strongly recommended of any technician to make sure they have a spare charger that is working well and/or a good set of batteries.
1. Lester Off-Board 8 amp Charger - The Lester Off Board charger part number BATC8LS – is a Transformer Driven 8 amp charger that has been working in this industry for over 17 years. It have an easy to operate switch that turns on the charger and has 2 LED’s to indicate charge rate and faults. The chargers operation is when AC and DC voltage are available (Note: 18 volts minimum DC) the Green Light flashes to indicate charge rate. A slow flash indicates the batteries need a charge and it is output 8 amps as the charging continues when the voltage approaches the bulk charge rate it starts flashing the Green LED rapidly indicating 2 amp rate until is sees a change of less than 500 mV and then turns Solid Green to indicate full charge cycle. The table below depicts operation of Green and Red LED operation and fault modes.
Red Light Gr een Light Function
Off Off No AC power or no battery connected Steady Steady Light test when AC connected Off Slow Blink Charging (< 80% charged) Off Fast Blink Charging (> 80% charged) Off Steady Normal charge completed Steady Off Undervoltage shut off, < 18.0 volts Slow Blink Off Overvoltage shutoff, > 33.96 volts Fast Blink Off Max timer shutoff, > 16 hours

2. Troubleshooting Chargers - When troubleshooting electronic equipment there is equipment necessary for checking and evaluation. The very first is a Multi-meter used for checking Resistance (continuity) – AC voltage from the Wall Plug – D.C. voltage from the batteries and Current the flow of the charger. The second is a load tester needed to evaluate (normally at 100 amps for 10 seconds) the batteries capacity to hold a charge rate.
The other two items recommended but not a necessity is a good set of batteries and/ or another known good charger.
Troubleshooting Tips
1. Check for battery voltage and polarity at chair’s charger input. The voltage needs to be at least 18 volts for the charger to turn on.
2. Check for continuity between cable (DC output and inside)
this is performed with a Multimeter
on the setting of resistance and with each of the connector points test the wiring from one end to the other which is inside the charger plug and charger.
3. Check for A.C. voltage. The wall outlet in North America should give a reading between 110 and 120 volts A.C.
4. Check for possible blown fuse. As a protection to the charger and chair components this fuse will go if it attains close to 15 amps of current - it will not operate charging of chair until replaced.

Motors
Intro: The motor is an essential part of any Power Chair and needs to be looked at annually or when an error occurs which point to one of 3 parts that make up Motor Assemblies. The motor assembly consists of the motor – brake – and gearbox. The Xperience and Xplore both use the same style motor and there are 2 varieties of motors to choose from. The next section shows parts of the Motor – Removal – and Diagnostics for trouble-shooting the motor.

Motor Assembly - Removal
Xperience
1. Take the 4 - 5/8” bolts from the Wheel Assembly shown in photo below:
2. Remove connector from motor control - access through front of chair box shown below:
Note: no tools necessary for step above Shows access and removal of connector for ease of removal – disconnect yellow communication connector as well
19
3. Remove shroud and release assembly - 10 mm and Phillips screwdriver required as well as pliers and 7/16” wrench
Remove shroud bracket assembly using a 7/16” open end and ratchet.
4. Remove cotter pin using long nose pliers to firmly remove
5. Disassemble the release mechanism further using a Phillips screwdriver to remove 3 screws holding attaching plate
20
Note: Pictures below show parts after removal and removal of Plastic restraining clip. This step is necessary for both motor and motor assembly removal.
6. Next step in removing complete assembly is to remove with a ratchet or open wrench the quantity 5 - 10mm head bolts. Note: remove rubber stopper prior to removing back bolt
21
If the plate is not removed you will need an open end wrench to remove the corner bolt near plate holder.
7. Finally to remove complete Gearbox and Motor the Chair needs to be moved on its side as shown.
This allows to move frame downward to remove assembly
22
Xplore Motor Assembly - removal
1. Follow details found on page 17 - removal of Drive Wheel and removal of motor connector from control.
2. This gives access to the motor and shroud assembly
Remove the 2 Phillips Screw with No. 2 Phillips Screwdriver
3. You now have access to the Motor Gearbox 5 - 10 millimeter head bolts – remove cotter pin first prior to the bolts with a pair of Long Nose pliers as mentioned on page 18 of manual
23
Place where Cotter pin should be removed
Removal of 5 bolts using ratchet with 10 mm socket
Unlike the Xperience the Xplorer Motor assembly can be removed if the bolts and cotter pin are removed no need to lay chair on its side.
Motor only on both chairs:
To remove only the motor a 3/16" allen key socket is needed and then remove the cotter pin from the holder on the frame as well as removing connector from control.

Troubleshooting Motors
1. Testing the motors you will have various means to do this by. The first way is if the motor has shut down and this is verifying what Diagnostic Code you have there are 2 main codes for left and right motor and 2 main codes for the brake and solenoid. They are as follows:
3B00 – for the M1 connection open – control does not see proper connection or resistance to Motor 1. Left Code for rear wheel drive units and right code(3C00) for Mid- wheel drive. (This is in reference to the Motor mounted on the left)
3C00 – for the M2 connection open – control does not see proper connection or resistance to Motor 2. Right Code for rear wheel drive units and left code(3B00) for Mid- wheel drive. (This is in reference to the Motor mounted on the right)
1505- for the Right Brake open – control does not see good
Brake resistance – two cases: normally open – close to
0 ohms or shorted - ultra high resistance.
1506 - for the Left Brake open – control does not see good
Brake resistance – two cases: normally open – close to
0 ohms or shorted - ultra high resistance.
2. The check is very simple as shown on page 16 - check the the small connector brake and large connector for motor.
15 – 16 ohms
0 – 2 ohms
25
3. The Motor may have a high resistance reading and this could be due to one or two or more brushes that are damaged. To extract, use a Large Straight edge screwdriver that matches to the brush holder. This eliminates stripping and basically ruining the entry of the brush housing. Once extracted check the brush for spring wear and length of Carbon material – it should be no shorter than 1//2 inch in length and brushes should be wearing smoothly on Commutator.
