Tripped Circuit Breaker
Troubleshooting a tripped treadmill ON/OFF circuit breaker or facility outlet circuit breaker.
Review the electrical requirements, see
"General Information" on page 5
.
It is extremely important to know whether it is the treadmill circuit breaker or the facility wall out-
let circuit breaker that trips. It is also extremely important to know when the breaker trip occurs,
choose one of the following trip events:
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
1
, the wall breaker
has tripped.
l
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 on 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 wall
breaker. If more than one treadmill loses power, the treadmills are on the same breaker.
o
If YES, advise the customer to have their facility wiring upgraded per Precor spe-
cifications.
o
If NO, continue troubleshooting.
IMPORTANT
: If the
AC

circuit feeding a treadmill 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 performed. More
importantly, a non-dedicated branch circuit may constitute a safety hazard to the tread-
mill operator.
l
Verify the wall outlets do not share neutral wiring and that each wall outlet is on an indi-
vidual branch circuit. An individual branch circuit will have its own load line, neutral line
and ground line. To verify that the treadmill is not on an 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.
o
If YES, advise customer to have their facility wiring upgraded per Precor spe-
cifications, and then continue to step 5.
o
If NO, continue troubleshooting
