6.3. THE DISPLAY SHOWS "E 3"
The machine displays this message if:
• it has detected a failure to actuate movement of the belt motor at the start of the training session;
• the movement of the belt motor is interrupted during the training session.
The most common causes are principally:
• One of the motor thermal cutouts has been tripped;
• The inverter has shut down for protection from a mains voltage fluctuation (spike or glitch).
In both cases it is recommended to turn off the machine — for at least one hour in the first case, and
for a few minutes in the second case — before resuming normal operation.
If the machine still does not operate correctly, follow the procedures (which differ depending on the
inverter model used) set out in the following paragraphs.
