SECTION 1—GENERAL GUIDELINES SECTION 1—GENERAL GUIDELINES WARNING SECTION 1 - GENERAL GUIDELINES contains important information for the safe operation and use of this product. DO NOT use this product or any available optional equipment without first completely reading and understanding these instructions and any additional instructional material such as Owner’s Manuals, Service Manuals or Instruction Sheets supplied with this product or optional equipment.
SECTION 1—GENERAL GUIDELINES DO NOT climb, go up or down ramps or traverse slopes greater than 9°. DO NOT attempt to move up or down an incline with a water, ice or oil film. DO NOT attempt to drive over curbs or obstacles. Doing so may cause your wheelchair to turn over and cause bodily harm or damage to the chair. DO NOT leave the power button in the On position when entering or exiting your wheelchair. DO NOT stand on the frame of the wheelchair.
SECTION 1—GENERAL GUIDELINES Carefully read battery/battery charger information prior to installing, servicing or operating your wheelchair. Charging Batteries DANGER When using an extension cord, use only a three wire extension cord having at least 16 AWG (American Wire Gauge) wire and the same or higher electrical rating as the device being connected. Use of improper extension cord could result in risk of fire and electric shock. Three prong to two prong adapters should not be used.
SECTION 1—GENERAL GUIDELINES Rain Test Invacare has tested its power wheelchairs in accordance with ISO 7176 “Rain Test.” This provides the end user or his/her assistant sufficient time to remove his/her power wheelchair from a rain storm and retain wheelchair operation. DO NOT leave power wheelchair in a rain storm of any kind. DO NOT use power wheelchair in a shower. DO NOT store power wheelchair in a damp area for an extended period of time.
SECTION 2—EMI INFORMATION SECTION 2—EMI INFORMATION WARNING CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.
SECTION 2—EMI INFORMATION WARNING Powered Wheelchair Electromagnetic Interference (EMI) 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 powered wheelchair's control system while using these devices. This can affect powered wheelchair movement and braking.
SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING Safety Inspection Checklists Initial adjustments should be made to suit the end user’s personal body structure, needs, and preferences. After initial setup, perform these procedures every time the product is serviced. All Wheelchairs CAUTION As with any vehicle, the wheels and tires should be checked periodically for cracks and wear, and should be replaced.
SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING ❑ Ensure seat is secured to wheelchair frame. ❑ Ensure seat release latch is not worn and is functional. Replace if necessary. ❑ Ensure arm pivot points are not worn and/or loose. Replace if necessary. ❑ Inspect for any loose hardware on the wheelchair. ❑ Inspect charger AC power cord for damage. Replace if necessary. ❑ Check that all labels are present and legible. Replace if necessary. ❑ Inspect electrical components for signs of corrosion.

DIAGNOSTICS CODE ERROR CODE DESCRIPTION SUB CODE* DETAILS OF ERROR CODE 8 E08 Controller Fault 00 Controller fault 9 E09 POSSIBLE SOLUTION NUMBER OF FLASHES SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING Check connections and wiring. Replace power module.
SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING SYMPTOM Motor chatters or runs erratically, or only one motor turns. Wheelchair veers to the left or right when driving on level surface. Gearbox is leaking Fluid. PROBABLE CAUSE SOLUTIONS Damaged connector or worn brushes. Bad motor or gear box. Ohm out motors. Check brushes and replace brushes if necessary. Replace motor/gearbox if high reading is present. Normal reading is 0-5 Ohms.
SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING SYMPTOM Motor is running then fails to restart when stopped. PROBABLE CAUSE SOLUTIONS Heavy load on the motors forcing controller into the current rollback mode. Leave power On and allow controller to count down, and recharge the batteries overnight with power On. Blown fuse in battery wiring harness. Replace battery wiring harness. Refer to Connecting/Disconnecting Battery Cables on page 101. Damaged motor.
SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING SYMPTOM PROBABLE CAUSE SOLUTIONS Bad connection or blown fuse. Check Joystick connection. Batteries are dead. No power to wheelchair motors. Loose battery connections. Check all connections and housings for damage. If you have blown fuse a new battery wiring harness must be purchased. Refer to Connecting/Disconnecting Battery Cables on page 101. Check battery voltage and replace if necessary.
SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING SYMPTOM Batteries have short driving range during a single charge. Battery Gauge falls off faster than normal. PROBABLE CAUSE SOLUTIONS Consumer not charging batteries long enough. Instruct consumer to charge for 8-10 hours minimum. Batteries may be weak. Perform load test or check “Battery Quality Menu” with the programmer. Refer to electronics manual. Refer to Field Load Test on page 30. Check programming settings.
SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING Field Load Test NOTE: For this procedure, refer to FIGURE 3.1 on page 31. 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.
SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING Charger Port Digital Voltmeter BATTERY QUALITY 0 to 2 volts Good 2 to 2.5 volts Poor 2.5 or more Bad FIGURE 3.1 Field Load Test Motor Testing NOTE: For this procedure, refer to FIGURE 3.2. 1. On the 4-pin motor connector, locate the two contacts in the RED and BLACK housings. Cap Motor 2. Set the digital multimeter to measure resistance (ohms). 3. Measure the resistance between the two motor contacts. NOTE: A normal reading is between .5 and 5 ohms.
