line, and ground line. Have a certified electrician verify the treadmill is powered from an
individual branch circuit:
o
If YES, advise customer to have their facility wiring upgraded per Precor spe-
cifications.
o
If NO, continue Troubleshooting.
CAUTION : The treadmill requires a 20-amp individual branch circuit grounded per
NEC (National Electric Code) guidelines or local region electric code.
l
Verify that the wire gauge is not to small to carry the required 20 amp load for long dis-
tance input power wire runs, the distance from the outlet to the facility power distribution
panel:
o
If YES, advise customer to have their facility wiring upgraded per Precor spe-
cifications.
o
If NO, continue Troubleshooting.
l
Verify that the input line voltage is not below the minimum required voltage level. For
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. Meas-
ure the treadmill input voltage with the circuit breaker switched "ON" and the running
belt stopped. Record the voltage. Then measure the voltage again using the instant-
aneous voltage drop using the min/max function on your volt meter while someone is
running on the treadmill at 7.0 MPH or higher:
o
If any measurement is below 108 Vac (US -120 Vac) or 200 VAC (International -
240Vac), advise the customer to have the facility wiring inspected by an elec-
trician.
o
If the measurements are at or above 108 Vac (US) or 200 Vac (International),
continue troubleshooting.
l
Does the treadmill ON/OFF circuit breaker trip immediately on power up:
o
If YES, it is likely that there is a shorted electrical component, inspect the input
line filter and lower control module for faulty/shorted wiring.
o
If NO, continue with the following steps.
l
Does the treadmill power up normally and then the ON/OFF circuit breaker trips after
the motor is started:
o
If YES, it is likely that there is a defective roller or a bad drive motor.
o
If NO, continue with the following steps.
l
Does the Drive Motor start up normally and then the ON/OFF circuit breaker trips after
an exerciser walks/runs on the running belt:
o
If YES, overloading is the most frequent cause of making the treadmill shut down.
Overloading most often occurs when heavy exercisers are running on a worn
belt. Tne deck/belt friction issue is also worsened by poor input line voltage. Over-
loading is often accompanied by error codes 27, 28, or 29. Verify the running belt
condition.
