INTRODUCTION Multimeter Tutorial MULTIMETER The Multimeter The multimeter is one of the most useful tools in the toolbox. It can be used to check wires, shorts, voltages, resistance, all manner of electrical circuits. This tutorial is designed to help clarify the symbols and socket options found on various multimeters. The Probes PROBES Probes connect the meter to the circuit. Simply touch them to the connections you want to measure and read the display.
INTRODUCTION Symbols This section describes the basic symbols used in a typical multimeter. AC This symbol means 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 This means Direct Current. This is the type of electrical power produced by a battery.
INTRODUCTION Health and Safety Good Working Practices 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.
INTRODUCTION • • 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 correct procedures. Contact your local authority for their recommendations.
INTRODUCTION Sources of EMI 1. Hand-Held Transceivers: The antenna is usually mounted directly on the unit. These include: • Citizens band (CB) radios • “Walkie-talkies” • Security, fire 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.
INTRODUCTION Electro Static Discharge 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 fields (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.

POWER BASE SECTION Rhythm & Groove Power Bases Batteries Safety 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” flammable and can cause explosion. This is why proper handing is mandatory at all times.
POWER BASE SECTION Battery Diagnostics How Long Should Batteries Last? An average of 1 to 1.5 years. Factors that affect battery performance: • Maintenance - Poor maintenance. • Charging - Improper charging shortens battery life. • Chair Components - Malfunctioning electronics, bad motors, electric brakes, and corroded wiring are just some of the factors that may affect battery life and performance.
POWER BASE SECTION Battery Types REMEMBER: IT IS THE RESPONSIBILITY OF THE INSTALLER TO KNOW WHAT KIND OF BATTERIES TO INSTALL IN THE CUSTOMER’S WHEELCHAIR! • • • • Deep-cycle batteries 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.

Section 5 Troubleshooting Tilt Does the chair have powered seating? If so, the slow driving may be a result of an active inhibit from the seating system. Start by identifing what seating compnents are on the chair. An inhibit can come from either the power recline or power tilt system. Bring your tilt and recline to the upright position. If the wheelchair is still in creep try to identify which component may be causing the inhibit 1. Locate the 6-pin connector (A) at the rear of the tilt (fig. 5.4.1).
Section 5 Troubleshooting Tilt cont. Power Chair Will Not Drive in Creep Speed when Tilted fAn external micro-switch is mounted next to the actuator in the rear of the tilt system. This micro-switch is closed when the tilt is lowered. The closing of this micro-switch allows a signal to be being sent to the control module through the 6-pin connector located on the back of the tilt. The signal informs the control module that the tilt is less than 16 degrees and that maximum speed should be used.
Section 5 R-net Fault Codes cont. Tilt 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. 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 flow to the actuator when reversing direction. 1. Selected the tilt mode on the Joystick or Omni. (fig. 5.6.1).
Section 5 R-net Fault Codes cont. Tilt Will Not Operate - cont. Warning: Use caution in the next step. Do not short the leads of the Multimeter together or damage may occur to the control module. 5. At the 6-pin connector on the cable leading to the control module, verify that battery voltage is present between the indicated pins (fig. 5.7.1). Note: The polarity of the voltage is not important since it is reverses when the opposite direction is selected. 6.
Section 5 Tilt Will Not Operate - cont. Note: Since the tilt actuator will not operate, it is only possible to check for one condition. Pick the condition below that best describes the position of the tilt system. 1 to 3 ohms 8. Tilt is in mid-stroke. (Fig 5.8.1) The value recorded is the resistance through the actuator motor windings. If this reading is not correct, replace the tilt actuator and retest. fig. 5.8.1 10. Tilt is in the full down position. (Fig 5.8.

If your reading is open, take a reading directly from the 6-pin recline actuator harness (fig 6.3.1) at pins 3 & 4. 6 5 4 3 2 1 5. If your reading is still open, replace the recline actuator and re-rest. If your reading matches the Recline Calibration Chart above, then replace the harness from the recline actuator to the ISM. fig. 6.3.1 6.
Section 6 Power Recline does not Operate 1. Verify that the recline has not been disabled in programming. If it has been disabled, enable the option and re-test. 2. If actuator resistance is lost, the actuator will no longer be displayed as an option on the joystick. To test the recline actuator resistance, locate the ISM mounted on the back of the wheelchair. (fig 6.4.1) 3. Disconnect the 2-pin connector at actuator port 5 (Fig 6.3.) Left Lights Actuator Channels 1 2 3 Inhibit 4 fig. 6.4.
Section 6 Power Shear Does not Operate 1. To test the Shear actuator resistance, locate the ISM mounted on the back of the wheelchair. 2. Disconnect the 2 pin connector at actuator port 1 (fig. 6.5.1) 3. Check for resistance at this harness, normal resistance would be 6 to 8 ohms when the actuator is in mid-stroke and greater than 1 m ohms when at either extremity. If you have verified resistance at this connection, Replace the ISM. fig. 6.5.
