11.2
No Display
If the display is not lit when you turn on the treadmill, check the following points:
•
Is the emergency stop mushroom released (or emergency stop button on the external
display)?
•
Is the treadmill connected to the power source?
•
Is the main switch on the power connector box switched on?
•
Did the device blow/melt a fuse(s)?
•
Can the fan that is used to cool the servo controller (on the
runner’s
right) be heard?
•
Does the socket to which the treadmill is connected supply power
(e.g. could the circuit breaker for the supply line have been triggered)?
•
Is the emergency stop magnet placed on the magnetic switch? Try to reposition.
11.3
Belt Does Not Move
If the display and/or lifting mechanism works but the treadmill does not accelerate when the [+]
button is pressed, do the following:
•
Ensure the emergency stop magnet is in place. Try to reposition the magnet.
•
Turn off the power at the main switch and unplug the power cord.
•
Check if the running surface belt is blocked by an object and if so, remove.
Wait at least 60 seconds and put the device back into operation.
11.4
Free Moving Running Surface Belt
It is always possible to rotate the running surface belt slowly when the drive is not engaged. The more
energy used to move the running surface, the greater the motor's braking effect (short circuit brake).
This behavior is normal.
When the drive is not engaged (i.e. STAND-BY mode) the running surface belt is slowed down by
short circuit of the three motor phases. A totally free-moving running surface belt might be a
defective short circuit relay or a broken wire.
If the treadmill is turned on by the switch on the display and the indicator in the display is active, this
is a sign that the motor is defective or it is a failure of the servo controller.
In both cases the treadmill must be disabled immediately according to the instructions in this manual.
11.5
Incline Does Not Work
Possible causes:
•
Sticking break or stalled motor (noise coming from incline motor)
•
Tripped incline limit switch
•
Broken chain or chain jumped off a sprocket
•
Incorrectly-adjusted potentiometer
