The
E6 error is normally related to the missed / incorrect reading of the
motor inclination position signal (VR) and depends on 99% of the tilt
motor or on problems in the connections. The motor board directly
passes the signal to the console, without any modification.
Therefore, the cases of E6 errors dependent on the engine board are
rather rare.
The
following indications are for Astar treadmill controllers but they
can also be replicated for other models.
The
operations to be performed if the controller is fitted with an Astar
controller & console are:
1)
reset + incline down to enter engineering mode
2)
press mode 4 times to enter test mode
3)
start to start testing mode
4)
incline up and down to test inclination
if
it moves up and down, check if the ADC value changes (if it does not
change, it means that the tilt motor signal is interrupted - broken
wire or badly connected)
if
it does not move, the motor connections are usually wrong or the
motor is stuck or broken, however, check whether LED 2 or LED 3
lights up.
The
board makes an auto-tuning at power-up so it may be that the
treadmill moves by itself when you install a new controller if the
console doesn’t get the VR incline signal.
The
console in some cases allows to adjust the inclination, but this
adjustment only affects the console and the inclination motor (it may
be necessary to do it when changing the incline engine).
On
some lower controller cards, there is a special LEARN button to be
used for this purpose (press it and power on).
One last note: the inclination motor has a thermal
sensor so if you start to go up and down to test the inclination
after a while back and forth the engine heats up and goes into
protection. You will get then the same error code.
