1. Check distance
between Flywheel of DC
Motor and Speed Sensor
is in between 5mm to
7mm.
If not, place it at correct
position.

High Frequency
Drive.
2. Check calibration
factor in S/W, if it is
correct, Calibrate the
Treadmill for speed and
elevation and then check
if problem is solved on
recalibration. If not follow
below points.
If Calibration factor is not
correct then correct it
from factor written on
treadmill and then
calibrate the Treadmill.
2. Check
LED1 on High
frequency drive
flashes each time
when the flywheel
completes one cycle.
If not, Check
whether
sensor connection is
loose, if yes, correct
it

moving at
all)
1. Run test Treadmill
program from S/W under
utilities menu
and click
on appropriate buttons
for speed increase and
decrease and check the
speed increase/

If LEDs are not flashing
then the problem lies in
Treadmill Controller or
calibration factor is
incorrect. If possible
check with another
Treadmill Controller. If
LEDs are glowing now
then change Treadmill
Controller.

controller, TPC
cable, DC Motor
2) Check if TPC cable is
OK by checking its
continuity.
If not cut both ends and
resolder the cable
( Refer
cable dig.1 for Cable
Details
).
3) Still belt is not
moving while testing the
Treadmill independently
then the problem
probably lies on the
Treadmill side. First
remove top cover from
Treadmill and check
whether the mains If it is not glowing, then
ensure that 230-volt AC
is reaching at mains
connector on High
Frequency Drive, If 230
volt is present, still LED
is not glowing then
change High Frequency
Drive.
