Tripped Circuit Breaker
Troubleshooting a tripped treadmill ON/OFF circuit breaker or facility power distribution
panel circuit breaker. Review the electrical requirements, see
and
Entry Assembly Wire Diagram" on page 247
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:
l
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.
If the facility outlet circuit breaker trips
l
Measure the facility wall outlet voltage. If the is approximately 0 Vac, the wall breaker
has tripped.
l
If there is power at the wall outlet, inspect the power cord, if damaged, replace the line
cord. If the line cord is not damaged continue with the following steps.
l
Verify whether there is more than one treadmill using the same outlet circuit breaker.
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:
o
If YES, advise the customer to have the facility wiring upgraded to provide one
individual branch circuit outlet per machine, see Precor specifications, see .
o
If NO, continue Troubleshooting.
IMPORTANT
: If the
AC

circuit providing the treadmill power is found to be a non-
dedicated 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 per-
formed. More importantly, a non-dedicated branch circuit may constitute a safety
hazard to the treadmill operator .
l
Verify the wall outlets do not share neutral wiring and that each wall outlet is on an
individual branch circuit. An individual branch circuit will have its own receptacle load
line, neutral line, and ground line. Have a certified electrician verify that each treadmill
is powered from an individual branch circuit, see
o
If YES, advise the customer to have the facility wiring upgraded to provide one
individual branch circuit outlet per machine, see Precor specifications, see .
