If a treadmill stops suddenly, it means a protective function works properly. This is normal function to protect the treadmill. As the result of
protective function, a code indicating the cause of error is displayed on the display console or the display panel of Motor Controller (or Motor
Inverter) which is located under motor hood. Motor is driven directly by Motor Controller according to the command from the console.
If this protective function occurs, turn off the treadmill and then turn on the treadmill after 20 seconds even though the cause is eliminated. Even
though the cause is eliminated, the treadmill stop due to protective function will remain unsolved if you turn on the treadmill within 20 seconds after
turning off the treadmill.
Motor Controller output current exceeds the rated current by more than approximately 180%.- The load is in abnormal condition like impact load.
- A main circuit element is defective.- The output is short
Overheated Motor Controller caused by worn or damaged belt and deck.
- Replace Motor Controller with new one. - - Check the cables and wires between motor and Motor Controller are loose or if there is any short between wires
- Input voltage of Motor Controller is too high.
- Check the input voltage fluctuates abnormally.
- Don’t push the striding belt backward.
- External noise
- Trouble in internal memory due to or high temperature.
- Cable connection between MPU and Motor Controller
- Replace Motor Controller cable with new one
- Replace Motor Controller with new one
- Input voltage of Motor Controller is too low.
- Instantaneous power failure
- Connect the treadmill to dedicated circuit.
- Supply stable power to treadmill
Overheated Motor Controller caused by worn or damaged belt and deck.
- Do not place heat generating device near the treadmill.
Replace the deck or belt.
Basically, initial lubrication is performed at factory, but the oil could be dried during transportation or stock in your warehouse.
As soon as you complete installing, please lubricate and then make sure that oil is enough or not as below.
1) Turn off treadmill.
2) Push the striding belt backward using your feet while holding the front handle bar or side handle bar.
3) You can judge whether the friction is enough or not by feeling the smooth move of the belt. Lubrication is needed if the belt is not pushed well.
# Lubricant prevents the belt and deck from being damaged by frictional heat, which extends life span of the deck and belt.
# Use the lubricant provided by Motus only.
How to manage automatic lubrication system (M990T, M990TL)
A certain amount of oil is lubricated automatically every lubrication interval which is preset at Manager Mode. Default lubrication amount and lubrication interval are set up to, for instance, 30cc and 500km, respectively, which can be set at Manager Mode. Therefore, it is recommended that fitness club manger set up the lubrication amount and interval according to club condition. A volume of lubricant tank is about 270cc, and if residual amount of oil is less than 20%, the warning SYMBOL is displayed on the screen with a beep. At that time, fill the tank as instructions below.
1) Turn OFF the treadmill and open motor hood.
2) Open the cap of oil tank by turning it with hand.
3) Fill the empty tank fully with the oil provided by Motus. Keep in mind that automatic lubrication system doesn’t work properly if oil is not filled full.
4) Close the cap of oil tank and put the motor hood in place.
5) Turn ON the treadmill. Message indicating oil lack will be still displayed on the screen with the beep.
6) To input “finishing oil-filling”, press buttons in the order as below.
Keep in mind that this step must be done after filling the tank fully.
7) The warning SYMBOL and beep disappears.
The belt is properly aligned at the factory before shipment. However, while delivering or exercising, the belt can be misaligned from the original center position. The correct alignment or striding belt is critical to the smooth operation of the treadmill.
When the belt is off center to either right direction or left direction
1) Level and stabilize the treadmill prior to any alignments or tracking adjustments.
* The belt may move off center by using the treadmill on uneven surface.
2) Turn on the treadmill and then check if the belt drifts off center or not while treadmill is operated with the speed of 5km/h for a few minutes.
3) Turn off the treadmill after keeping in mind whether the belt is off center to which direction, left or right.
4) Make sure the striding belt has completely stopped.
5) Find the right belt tensioning bolt in the rear end cap of the treadmill. Make tracking adjustments using the 10 mm hex key wrench provided as shown.
# If the belt is off center to the right, turn the right adjusting bolt 1/4 turn clockwise, which brings the striding belt back to the left.
# If the belt is off center to the left, turn the right adjusting bolt 1/4 turn counterclockwise, which brings the striding belt back to the right.
Note: Do not turn the adjusting bolt more than ¼ at a time. Over-tightening the bolt can damage the treadmill. Do not exceed one full turn of the adjusting bolts in either direction.
6) Turn ON the treadmill, press START/STOP, and then operate the treadmill with the speed of 5km/h.
7) Observe the striding belt for a few minutes. The belt should be centered on the deck.
8) If you need additional alignment, repeat step 2) through 7) of this procedure until the belt is properly aligned.
CAUTION: If you hear any chafing, the belt is not center-aligned or the belt appears to be getting damaged, stop the treadmill and contact authorized local dealer.
