Introduction

This Service Manual provides safe and efficient step-by-step test and service procedures for 97Ti, 97Te, 95Ti, 95Te, and 93T Treadmills. The “Ti” designation stands for Light Emitting Diode (LED) Consoles and the “Te” designation stands for Liquid Crystal Display (LCD) Consoles. Illustrations in this manual reflect service view(s) to compliment the step-by-step procedure. Unnecessary views or details may not be illustrated for the sake of clarity.

When a service problem occurs, it is recommended that you first refer to “Troubleshooting” in Section 1 or “Diagnostics” in Section 2. Refer to “How To…” in Section 3 for actual service procedures, and in addition, Special Service Tools will be listed otherwise, standard tools should be used. Refer to “Electronics” in Section 4 for Block Diagrams and Connector locations. Refer to “Miscellaneous” in Section 5 for ID Tag Location, Maintenance, and other general information pertinent to the product.

Life Fitness Model 97Te, 95Te, 97Ti, 95Ti and 93T Arctic Silver Treadmills

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.

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.
