Tripped Circuit Breaker

Troubleshooting a tripped treadmill ON/OFF circuit breaker or facility power distribution panel
circuit breaker. Review the electrical requirements, see
Assembly Wire Diagram" on
It is extremely important to know whether the tripped circuit breaker is the treadmill ON/OFF
circuit breaker or the facility wall outlet circuit breaker. It is also extremely important to know
when the breaker trip occurs, note which one of the following events best describes when the
circuit breaker tripped:
Immediately on power up
l
After the belt starts but before the exerciser walks onto the belt
l
After the exerciser walks onto the belt.
l
If the facility outlet circuit breaker trips
Measure the facility wall outlet voltage. If the is approximately 0 Vac, the wall breaker
l
has tripped.
If there is power at the wall outlet, inspect the power cord, if damaged, replace the line
l
cord. If the line cord is not damaged continue with the following steps.
Verify whether there is more than one treadmill using the same outlet circuit breaker.
l
This will be especially evident if two or more treadmills shutdown at the same time. To
verify if multiple treadmills are sharing the same wall breaker, manually switched OFF
the facility outlet circuit breaker. If more than one treadmill loses power, the treadmills
are on the same breaker:
If YES, advise the customer to have the facility wiring upgraded to provide one
o
individual branch circuit outlet per machine, see Precor specifications, see
page 10.
If NO, continue Troubleshooting.

IMPORTANT: If the AC circuit providing the treadmill power is found to be a non-ded-
icated branch circuit or a circuit equipped with a capacity of less than 20 amps, the AC
circuit must be corrected before any reliable Troubleshooting can be performed. More
importantly, a non-dedicated branch circuit may constitute a safety hazard to the tread-
mill operator .
Verify the wall outlets do not share neutral wiring and that each wall outlet is on an indi-
l
vidual branch circuit. An individual branch circuit will have its own load line, neutral line
and ground line. Have a certified electrician verify that each treadmill is powered from
an individual branch circiut, see
If YES, advise the customer to have the facility wiring upgraded to provide one
o
individual branch circuit outlet per machine, see Precor specifications, see
page 10.
If NO, continue Troubleshooting
