TEST PROCEDURES

INCLINE POTENTIOMETER CALIBRATION TEST

This test can correct E1: Minimum conditions and aid in diagnosis of incline problems with finding zero or target incline.

455:

Set voltmeter to Ohms (Ω) with treadmill unplugged from wall Place 1 voltmeter lead on pin 3 (Blue) and 1 lead on pin 2 (Orange) Check for 800 Ohms

455:In calibration mode before pressing Start, the Distance window displays the incline number. With the treadmill at zero, the number should be between 160 and 180. 0 often indicates a wire harness misconnection or failure of signal to panel.

As the unit inclines during calibration, watch the numbers in the Distance window, if they do not increase by at least 60 from the zero value, an E1: Minimum error will result. Then the zero value may need to be reset to a lower value.

If incline potentiometer needs adjustment, remove swivel pins and use Up and Down keys to make adjustment. (See diagram on T-6)

VOLTAGE TO INCLINE MOTOR TEST

This test is utilized in conditions of No Incline Movement, Incline Fluctuation, or E1: Minimum.

Set voltmeter to AC volts. To access incline plug, PWM screws may need to be removed. Place voltmeter leads across White and Black while pushing UP button

10 VAC indicates normal PWM output, 0 VAC signals no output

Place voltmeter leads across Red and White while pushing Down button 110 VAC indicates normal PWM output, 0 VAC signals no output
