If The Treadmill Breaker (Power Switch) Is Tripped - Precor TRM10/GEN06 Service Manual

If the Treadmill breaker (power switch) is tripped:

1 Verify the wall outlets do not share neutral wiring and that each wall
outlet is on a individual branch circuit. A individual branch circuit
will have its own load line, neutral line and ground line. To verify
that the treadmill is not on a individual branch circuit use an AC
voltmeter measure from the hot contact of one AC receptacle to the
neutral contact of another AC receptacle. If AC line voltage is
present then the treadmills are sharing neutral lines.

If YES, advise customer to have their facility wiring upgraded per
Precor specifications, and then continue with step 2.

If NO, continue with the following steps.
2 Verify that there long branch run with inadequate gauge wire.

If YES, advise customer to have their facility wiring upgraded per
Precor specifications.

If NO, continue with the following steps.
3 Verify line voltage. Low line voltage for the U.S. is anything below
108VAC, measured while the treadmill circuit breaker is turned "ON",
but the running belt is idle. For international, low line voltage is
anything below 200VAC while the treadmill circuit breaker is turned
"ON" and the running belt is idle. Measure the line voltage with the
treadmill circuit breaker is turned "ON", but the running belt is
idle. Make note of the voltage. Then measure the voltage again using
the instantaneous voltage drop using the min/max function on your volt
meter while someone is running on the treadmill at 7.0 MPH or higher.

If any measurement is below 108VAC (US) or 200VAC (International),
advise the customer to have their facility wiring inspected by an
electrician.

If the measurements are at or above 108VAC (US) or 200VAC
(International), continue with following steps.
4 Does the treadmill trip its breaker immediately on power up?

If YES, it is likely that there is a shorted component (line filter,
lower control module) or faulty/shorted wiring.

If NO, continue with the following steps.
5 Does the treadmill power up, but trips the breaker after the motor is
started?

If YES, it is likely that there is a bad roller or bad drive motor.

If NO, continue with the following steps.
6 Does the drive motor start up fine, but trips the breaker after a user
walks/runs on the running belt?

If YES, Overloading is the most frequent cause of treadmill shutting
down. Overloading is most often caused by excess deck/belt friction,
but can be made worse by line voltage conditions. The overloading
condition happens more often with heavier runners, but never
walkers. In high user clubs (10 hours or more of use per day), the
decks/belts will wear out much faster than at other locations,
