TRACKMASTER Troubleshooting
Inverter Drive
You should not change the Inverter Drive programs unless directed to do so by the
factory. To check the programming of the drive, contact your distributor for instructions
and settings. Consult your distributor before making changes. (For wire routing, see
Appendix B.)
The instructions in this section are based on the assumption that the repairs will be
performed by a properly trained and authorized repair technician. All motorized equipment
is potentially dangerous if used incorrectly. Read the precautions and this owner’s manual
before attempting any repairs. If the scope of the repairs exceeds the technician’s knowledge
or experience, call your distributor for the name of the nearest qualified service
repair facility.
Power On Indicator Not Illuminated
1. This procedure requires the use of a meter that is capable of reading at least 250 VAC
and measuring ohms.
2. Turn treadmill main power switch to OFF. Unplug the treadmill power cable from the
wall receptacle.
3. Measure the voltage at the wall outlet for correct voltage level. If voltage is not correct,
reset circuit breaker. If voltage is correct, proceed to next step.
4. Plug the treadmill power cable into the wall receptacle. Turn treadmill main power
switch ON.
5. Measure voltage at one of three locations: Inverter between L1 and L2; at power supply
PCB JP2 pin 1 to 3; or power supply PCB JP2 pin 2 to 4. If voltage is not present,
proceed to the next step. If voltage is present, check connections at power indicator.
6. Measure voltages at C/E filter output. If voltage is not present, check connections at
C/E filter input. If connections at C/E filter input are good, measure voltage at C/E filter
output. If voltage is not present, check connections at main voltage circuit indicator.
7. If connections at the main circuit breaker are good, turn main power switch to OFF,
and unplug the treadmill from the wall receptacle. Check the continuity of each
conductor of the power cord. If the power cord is good, check the function of the main
power switch in the ON and OFF positions.
Main Circuit Breaker Trips When Powering Up
If the main circuit breaker trips when the treadmill is first turned on, the main circuit that
the treadmill is on may be overloaded. This will happen even if the treadmill is on a
proper, dedicated line. Refer this problem to your local electrician and check that the service
panel circuit breaker is a high magnetic breaker.
