3. Speed control signal on motor amplifier should measure .250 VDC per mill per hour E.G.

NOTE:

Measurement taken at J1, PIN 1 to PIN 2 (ground)

1mph = .250 VDC

2mph = .500 VDC

4mph = 1.00 VDC

8mph = 2.00 VDC

If speed control signals are OK, proceed to step 4.

4. Check Amplifier Output. The Output Terminals are located on top of amplifier and are

designated “m+” and “m-”. The Output voltage should be:

1mph = 32 VAC, 2mph = 52 VAC

NOTE:

Remember to use the volts A.C. selection on your meter. The Amplifier is pulse width

modulating, therefore, A.C. scale is required.

If amplifier output is OK, proceed to step 5.

5. Check Motor Resistance. The motor has a winding resistance of 1.3 to 3 Ohms. The

value is dependent on commutation position. If resistance reading is significantly higher

the windings or brush contacts are defective.

To measure resistance turn treadmill power OFF. Place meter lead across terminals

marked “m+” and “m-”. Set meter scale to the lowest resistance selection. Check resis

tance in several commutator positions by rotating motor shaft 9.0 degrees for every one

revolution.
