6.4. 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 power supply to the inverter is cut off by the power isolating board.
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.
