1.4 Protective Function & Display Code
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.
