20. The belt power test is similar to the belt speed test except that the SPEED keys control the
power bits (PWM value) instead of the belt speed.
21. The same (see step 16) values will be displayed as in the belt speed test.
22. This test is valuable in diagnosing treadmill response to load conditions. As load is
increased, the power bits are kept at a constant value (as set via the SPEED keys) and the
current and belt speed will vary proportionately to the load.
23. It is suggested that you perform this test on a treadmill known to be in excellent operating
condition. Note the values displayed at a fixed power bit reading (as set by the SPEED
keys) and your body weight. Those values may then be used to benchmark the operation of
treadmills you are diagnosing.
24. Press and hold the STOP or press the ENTER key to proceed to the fan test.
25. This test displays the operating speed of the drive motor cooling fan in RPM. If the fan
speed is less than 1000 RPM, the fan should be replaced.
26. Press the STOP or the ENTER key to proceed to the circuit breaker test.
27. The message HOLD ARROW KEY TO TRIP will be displayed. When the arrow key is held,
the message BREAKER WILL TRIP 3 2 1 will flash on the screen one word at a time.
Shortly after the 1 is displayed, the circuit breaker will trip. If the arrow key is released before
the circuit breaker trips, the test will be terminated.
28. The circuit breaker test is the last test in the diagnostics routine. If you do not wish to cause
the circuit breaker to trip, press the RESET, STOP or the ENTER key to exit the diagnostics
routine.
