indication LED2 is
glowing on High
frequency drive.
If LED is glowing, still
belt is not moving then
change high frequency
drive
4) The last step is to change the DC motor. But
before changing do the following cold test.
Cold test for DC motor:
a.
Remove 3-pin top of Treadmill from mains
supply.
b
. Remove all the two wires of DC motor
c
. Ensure that there is no continuity between
Treadmill body and all the connectors of DC motor.
d.
In case of pmdc motor, ensure that the armature
resistance is nearly equal to 2-3 ohms.

Speed and
elevation not
as per
protocol
through
software.
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.
Treadmill
controller, silicon
oil.
Confirm that Treadmill
and PC, both are
connected to one and
the same phase only.
Always give power from
one and the same
extension
board
to
Treadmill and ensure
that Earth voltage is
less than 5V.
If not connect both
treadmill and PC to
same phase.
Confirm that earth point
of PC and Treadmill is
shorted with 24/36 wire
externally.
If not short the both
earth points with 24/36
wire externally.
Check continuity of TPC
and serial port cable.
Setting
and
speed
sensor alignment.
If needed re-solder the
same
(Refer
cable
dig.1
for
Cable
Details).
Check if and speed
sensor alignment is OK.
If not place it correctly.
Also If conveyor belt is
too tight then this
problem occurs
.
In that case loosen the
belt accordingly and put
silicon oil under the belt.

Speed goes
on increasing
when we
switch on the
Treadmill.
(Uncontrolled
speed)
Check sensor connector
is properly connected.
Ensure that it is not
loose.
If not connect it properly.
Sensor coil, High
frequency drive.
Check continuity of TPC
cable between High
frequency drive and
Treadmill controller.
if needed re-solder the
