Error 29 - Excessive AC Input Current
Description
This error code is used on three phase AC drive motor systems. If the
AC input current reaches a value slightly over 20 amps R.M.S. or there
is an instantaneous AC input current spike of 65 amps, the drive motor
system will shut down and an error 29 will be logged.
Possible Causes
1
If the facility is powered by a generator, or frequently switches
between city and generator backup voltage, interruption of the
treadmill operation may occur.
2
The neutral wires are shared on multiple outlets.
3
The running belt and/or running bed is badly worn.
4
A shorted lower control module (IFT module).
5
A shorted drive motor is causing the high power demand.
Possible Remedies
1
Call Precor support for lower board built specifically to handle
generator power.
2
The outlet is not on a dedicated 20 amp branch circuit. Using 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 they are sharing neutral lines. If YES, advise customer
to have their facility wiring upgraded per Precor specifications.
This condition would require a licensed electrician to correct the
problem
3
A clamp-on AC ammeter must be used to determine the amount of AC
input current being drawn by the treadmill under no load and loaded
conditions. Follow the troubleshooting procedure,

(on page 68).
4
A known good drive motor power module must be substituted for the
existing drive motor power module.
5
A known good drive motor must be substituted for the existing drive
motor.
