123. 123 Nautilus® Commercial T9 Series Treadmill Service Manual Appendix B Using a Multimeter How to Use a Multimeter This is a basic overview of mutlimeters. For in depth directions, please use the manual provided with your multimeter. Whats Does a Multimeter Do? A multimeter combines the functions of three instruments: ammeter (measures current), voltmeter (measures voltage), and ohmmeter (measures resistance). Electronic signals are usually thought of in terms of voltage. For that reason, and because it is an easier measurement to take, we will use the volts setting. We will not want to use the ammeter setting to troubleshoot fitness equipment. The ohmmeter setting is used to determine whether there is an open circuit (a bad connection or break in the wires) or a short circuit (two wires that normally would not come in contact with each other have been pinched together or crossed in some way). Ohmmeters work by passing a small current through the wire or component and measuring the voltage produced. Type of Multimeters Multimeters are available in digital and analog models. Digital meters give an output in numbers usually on a LCD. Analog meters move a needle along a scale. We recommend using a digital meter. While analog meters can be very cheap, they are difficult for beginner to read accurately, especially on resistance scales. Also, the components are delicate and easily damaged. Settings For the beginner the multimeter can be intimidating because of the range of settings available. The diagrams on page 75 show what settings to use when checking voltage and resistance on the fitness equipment. Perhaps more importantly, it shows which settings are not needed. There are two types of digital multimeters commonly available: • switched range and • autoranging. Switched range meters require you to choose the appropriate position from the many choices available on the dial. For example, if the dial is switched to 20VDC, 20 volts is the maximum voltage that can be measured. This is important when you want to read small increments in voltage accurately. For example, if the required voltage is 13.5 volts and the meter is set too high, you may only see 13 volts on the readout. Setting the meter to a lower maximum will show 13.5 volts. Autoranging meters automatically adjust the range to give an accurate reading. This type of meter is more expensive but much easier to use. SECTION 7: APPENDIXES

125. 125 Nautilus® Commercial T9 Series Treadmill Service Manual Checking Resistance Use this procedure to check for broken wires: 1 Set the multimeter to the lowest OHMs (resistance) range. 2 Attach the test leads on both ends of the wire being tested. 3 Observe the reading. • A short circuit will read less than approximately 3 ohms. This is the correct reading for an undamaged wire. • An open circuit will usually read infi nite; on a digital meter it will have an error code. This signals a broken or cut wire. Use this procedure to test for crossed wires. In most circumstances all indivudual wires in a cable will be insulated from each other. When a wire is pinched, it becomes short circuited to an adjacent wire. This can cause problems resulting in blown fuses or fried components. 1 Set the multimeter to the lowest OHMs (resistance) range. 2 Attach one test lead of the multimeter to one wire and check all adjacent wires. This can all be done at one end of the cable. However, the other end of the cable must be disconnected from the circuit board. All wires should be insulated from each other and therefore test open. 3 Observe the reading. Checking Voltage Use this procedure to check voltage output: 1 Determine whether the voltage is AC or DC voltage, and choose the appropriate setting on the multimeter. 2 Set the multitmeter to the lowest setting that is still higher than the highest output of the component being tested. 3 Place the black and red leads or probes on the appropriate corresponding wires, pins, or connectors. 4 Observe the reading, and proceed according to the troubleshooting sections in this manual.

Operational Error Codes What this means First Action Second Action Third Action Fourth Action DRIVE ERROR Occurs when the VSD PCBA detects too low or too high of a voltage on the DC drive bus. Verify input line voltage is within specifications. Error indicates voltage is too low or high. Ensure all cables from the configuration plate to the VSD PCBA are connected. Cable going to P20 on VSD PCBA is most likely to cause problem. Replace VSD PCBA. Replace Configuration Plate. DRIVE PWR ERROR Early versions of software displayed this error as “ABS ERROR” or “POWER LOSS ERROR” Can occur during program operation. Treadmill goes to idle and stops quickly. This Error can denote any of the following: 1 - The DC bus that powers the walkbelt is too low or high. 2 - The thermal switch on the walkbelt motor is open due to the motor overheating. 3 - The circuitry that measures the walkbelt motor current has failed. Verify input line voltage is within specifications. Error indicates voltage is too low or high. Let walkbelt motor cool down and cycle power. Motor thermal switch may open due to worn belt and deck. Ensure all cables from the configuration plate to the VSD PCBA are connected. Cable going to P20 on VSD PCBA is most likely to cause problem. Replace VSD PCBA. If problem persists replace Configuration Plate. DRV RESET The processor on the VSD PCBA cannot communicate with the motor control IC on the VSD PCBA. Ensure all cables from the configuration plate to the VSD PCBA are connected. Cable going to P20 on VSD PCBA is most likely to cause problem. Replace VSD PCBA. GRD LIMIT ERROR Grade motor beyond its lower (05) or upper (15%) limits. Press [CLEAR]. Go to Diagnostic Mode (Speed Increase, 6, ENTER), then scroll to "GRADE ACT" using the Speed Increase and Speed Decrease keys. If the grade is reading over 15% or less than 0%, attempt to adjust grade up or down using the Grade Increase and Grade Decrease keys. If "GRADE ACT" is over 15%, check to see if grade pot (sensor cable) is unplugged from AC Drive Board. Otherwise, mechanically disconnect grade motor from frame, & manually rotate grade shaft clockwise (for up) and counterclockwise (for down), while in diagnostic mode to view current grade position and turn the shaft in the correct direction. Then reassemble. Replace grade motor. Replace VSD PCBA. If problem persists replace Configuration Plate.
