10.2 No Display
If the display is not lit when you turn on the treadmill, check the following points:
Is the treadmill connected to the power source?
Is the main switch on the power connector box switched on?
Check that the power main’s input fuse is properly functioning (replace if defec-
tive).
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)?
10.3 Running Surface 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.
Ensure the emergency stop button is in the released position. If button is activated,
twist clockwise to release.
Check if the running surface belt is blocked by an object and if so, remove.
Turn off the power at the main switch and unplug the power cord. Wait 60 seconds
before reconnecting to power and turning on the main switch.
10.4 Free Moving Running Surface
It is always possible to rotate the running surface belt slowly when the drive is not en-
gaged. 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.
10.5 Incline Does Not Function
If the incline motor makes noises, a brake may be stuck or the motor may have
stopped.
Check if the incline-limit switch has been tripped.
Ensure that the chain is not broken and has not slipped from the sprocket.
Ensure that the potentiometer is set properly.
10.6 Irregular or Flashing Display
Ensure that the treadmill is connected to an independent power line.
Verify power source is rated to match the electrical specifications listed on your
unit’s serial label.
The power supply for the display on the interface card may be defective; contact
WOODWAY Customer Service.
10.7 Sources of Electromagnetic Interference
Close proximity to, for example, X-ray equipment, powerful motors, or isolating trans-
formers must be avoided because of possible electromagnetic interference.
Electromagnetic interference can affect the operation of your treadmill.
