Theory of Operation

The Treadmill is an electromechanical device that operates on A/C Voltage System and is controlled through the electronics in the Display Console. The key components that make up the Treadmill are the Unit Frame, Electric Motor and Motor Controller, Belt and Deck, Pulleys and Rollers, and the Display Console.

Initially the Line Filter receives the voltage. It is to the Motor Controller and other various electrical and electronic components that activate all the mechanical devices. The operator ultimately controls all electromechanical devices through the Console Display and with a touch of a finger can make settings and adjustments to Speed, Incline, and Custom Workout Programs.

The Unit Frame is critical not only to support the operator but also to support the electromechanical devices and the unit’s overall appearance. Although the frame is a non-maintenance item, its design and structure are essential to providing years of safe and reliable service.

The most critical parts on the Treadmill are the Striding Belt and Deck. Regardless of all other components, the success of a good Treadmill is its Striding Belt and Deck. The Deck is made up of a special particleboard, which allows for flexibility and long wear. The Waxless Striding Belt allows for self lubrication to ensure long life to both belt and deck. Under the Deck are the Lifesprings™, which are designed to support and absorb the shock load.

The Striding Belt is designed to endure constant stress loads. It is mounted directly over the Front and Rear Rollers. The Main Drive Motor has a Pulley on the end of its shaft, which is connected by a Drive Belt to the Front Roller Pulley. The Rear Roller is freewheeling. The Striding Belt tension is adjustable by means of Adjusting Bolts, which are located at the ends of the Rear Roller. When turned, they are used to adjust belt tension and belt centering. In order to increase belt and deck life, it is important to properly keep all areas of the machine clean.

The Display Console is the brain center of the Treadmill. It is here where all electromechanical operations are controlled for specific program operations. Depending on the Display Console, various selections and settings can be easily accomplished either through a Numeric Keypad or Up/Down Arrows. The Display Console allows the operator to selectively choose the program and input pertinent statistical information such as Weight, Age, Language, etc.

The Treadmill is by far one of the most popular pieces of all cardiovascular exercise equipment. With proper routine preventative maintenance and care, it will provide a lifetime of healthy cardiovascular exercise.

TROUBLESHOOTING GUIDE

NO POWER TO TREADMILL

In order to diagnose NO POWER to Treadmill, the Motor Cover must be removed, and the Treadmill must be plugged into an electrical outlet. Use the following TROUBLESHOOTING CHART to take the proper corrective action for NO POWER TO TREADMILL. In conjunction with this Chart, refer to the next page to reference Test Points (TP1 through TP5) on the Electrical Schematic.

STEPS	INSPECT	ACTION
1	Line Cord Voltage	Remove the Line Cord Bracket, unplug
		the Line Cord from Treadmill, and then
		test for Line Voltage.
2	Power Switch	Turn the Unit Power Switch ON, and test
		for Line Voltage at TP1.
3	Line Filter	Turn the Unit Power Switch ON, and test
		for Line Voltage at TP2.
4	Circuit Breaker	Turn the Unit Power Switch ON, and test
		for Line Voltage at TP3.
5	Motor Controller	Turn the Unit Power Switch ON, and test
		for Line Voltage at the Motor Controller
		Cable at TP5.

6	Auto Transformer	Turn the Unit Power Switch ON, and test
	and Wax/Lift	for 120v AC at the Wax/Lift Board Cable
	Board	at TP4.
		NO LEDs are lit on the Wax/Lift Board.

Fuse No. 1 is open.

Fuses No. 2 or 3 are open.

RESULTS

If Line Voltage is present, then continue on to Step 2.

If Line Voltage is not present, then test for Voltage at wall outlet. If no voltage is present, then check the Main Service Breaker at the Facility. If wall outlet voltage is present, then replace the Line Cord.

If Line Voltage is present, then continue on to Step 3.

If Line Voltage is not present, then replace Power Switch.

If Line Voltage is present, then continue on to Step 4.

If Line Voltage is not present, then replace the Line Filter.

If Line Voltage is present, then continue on to Step 5.

If the Line Voltage is not present, then reset the Circuit Breaker, or if necessary replace it.

If Line Voltage is present and NO LEDs are lit then check to see if the Motor Cable is unplugged or damaged, and replace as necessary.

If Line Voltage is present and NO LEDs are lit, then check to see if the Motor is overheated or is damaged. With the Motor unplugged, OHM out the two blue wires using a Multi-Meter. If there is NO Continuity, then replace Motor. If NO Line Voltage is present, then check Cables between the Power Box and Motor Controller, and replace as necessary.

Check for damaged cables and replace. If the cables are not damaged, replace the Auto Transformer.

Remove the Wax/Lift Board from the Treadmill. Check fuses 1, 2, and 3, with the Multi-Meter set on resistance. If the fuses are good, then test the power cable from the Power Box to the Wax/Lift Board for 120 Volts. If fuses are open, then replace the Wax/Lift PCB.

Inspect the Wax/Lift Board for any signs of damage. If damaged, replace the Wax/Lift Board.

Inspect cabling from the Wax/Lift Board to: Frame Tag, Motor Controller, Negative Switch, and Lift Motor Home Switch. If cabling is damaged, then replace as necessary.

Check for a shorted wire at the Lift Motor. The resistance is checked at the: Black to Red wire, which should read about 30 OHMS; the White to Red wire should read 15 OHMS, and the White to Black wire should also read 15 OHMS. If any of these wires register ‘0 OHMS’, then replace the Lift Motor.

NO POWER TO TREADMILL CONSOLE

Use the following procedure to troubleshoot No Power to the Treadmill Console.

1.Turn the Power OFF to the Unit.

2.Remove the Console Assembly to gain access to the Main Wiring Harness (P1). Leave all cables connected for testing.

3.Turn the Power back ON.

4.Place the BLACK Negative lead of the Multi-Meter on Pins No. 1 (yellow) and 2 (orange) to obtain a ground.

5.Place the RED Positive lead of the Multi-Meter on the corresponding wire to the verify voltage.

6.Following the Troubleshooting Chart below to verify problem.

Check for shorts in cables.

SOLUTION

If Voltage is present and the Console is not ON, then replace the Console PCB.

If NO Voltage is present, then check the corresponding Wax Lift Board Fuse.

If Voltage is present and the Console is not ON, then replace the Console PCB.

If NO Voltage is present, then check the corresponding Wax Lift Board Fuse.

If Voltage is present and the Console is not ON, then replace the Console PCB.

If NO Voltage is present, then check the corresponding Wax Lift Board Fuse.

INITIAL SETTING OF THE REAL TIME CLOCK

As part of the initial installation of the treadmill, the real time clock may be configured to the local time. Initially the real time clock is set to Greenwich meantime (GMT) which is the mean solar time for the meridian at Greenwich, England, used as a basis for calculating time throughout most of the world. Upon powering up the unit the following message will be displayed:

IF YES PRESS ENTER

IF NO PRESS CLEAR

If the user wants to set the real time clock to the local time, the user must press the ‘ENTER’ key.

The user will be asked to set the display mode. The two display modes are 12-hour mode with AM/PM or 24 hour mode with no am/pm. displayed. The message will be:

By pressing any of the arrow keys, the user toggles between the two modes. Once the mode is set, press the ‘ENTER’ key to continue.

After the display mode is set the user will now be asked to set the local time. The following message will appear:

“CLOCK SET TO GMT”, “USE ARROW KEYS TO ” “CHANGE SYSTEM CLOCK”, “TIME KEYS - HOURS”, “INCLINE KEYS-MINUTES”, “SPEED KEYS – SECONDS”

By pressing the specific arrow key, the user can set the real time clock to the local time. After setting the local time, press the ‘CLEAR’ key to exit the real time clock setting mode.

The message “UPDATING CLOCK” will appear in the message center. The unit will then continue with the normal powering up sequence.

If the user does not want to set up the real time clock at this time, a ‘CLEAR’ key can be pressed to clear the initial message. The unit will continue with it’s normal powering up sequence. The unit will ask a total of 5 times upon powering up if the real time clock wants to be set. After the 5th time the message will no longer appear. Refer to clock configuration to change the clock settings.
