Verify the wall outlets do not share neutral wiring and that each wall outlet is on an
l
individual branch circuit. An individual branch circuit outlet will have its own load line,
neutral line, and ground line. Have a certified electrician verify the treadmill is
powered from an individual branch circuit:
If YES, advise customer to have their facility wiring upgraded per Precor spe-
o
cifications.
If NO, continue Troubleshooting.
o
CAUTION: The treadmill requires a 20-amp individual branch circuit grounded per
NEC (National Electric Code) guidelines or local region electric code.
Verify that the wire gauge is not to small to carry the required 20 amp load for long dis-
l
tance input power wire runs, the distance from the outlet to the facility power dis-
tribution panel:
If YES, advise customer to have their facility wiring upgraded per Precor spe-
o
cifications.
If NO, continue Troubleshooting.
o
Verify that the input line voltage is not below the minimum required voltage level. For
l
1
120 VAC (U.S.) installations; the minimum acceptable line voltage is 108 Vac. For
240 VAC installations (international), the minimum acceptable line voltage is 200 Vac.
Measure the treadmill input voltage with the circuit breaker switched "ON" and the run-
ning belt stopped. Record 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 108 Vac (US -120 Vac) or 200 VAC (International
o
- 240Vac), advise the customer to have the facility wiring inspected by an elec-
trician.
If the measurements are at or above 108 Vac (US) or 200 Vac (International),
o
continue troubleshooting.
Does the treadmill ON/OFF circuit breaker trip immediately on power up:
l
If YES, it is likely that there is a shorted electrical component, inspect the input
o
line filter and lower control module for faulty/shorted wiring.
If NO, continue with the following steps.
o
Does the treadmill power up normally and then the ON/OFF circuit breaker trips after
l
the motor is started:
If YES, it is likely that there is a defective roller or a bad drive motor.
o
If NO, continue with the following steps.
o
Does the Drive Motor start up normally and then the ON/OFF circuit breaker trips after
l
an exerciser walks/runs on the running belt:
