T3NM : Motor Temperature Cutback

To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.

  • Ensure fan is always running when machine is powered on.
  • Ensure fan is blowing air toward the motor (inward).
  • Ensure fan is clean and moves freely.  Remove any obstructions in front of fan grille.
  • Ensure no hot air (from other heat sources) is being directed toward the fan.
  • Ensure system ambient temperature is below 120F (48C).

 

  • Mix chamber is too large for set pressure.
  • Set pressure is too  high for given mix chamber.

This cutback occurs to preserve motor life.  If the motor gets too hot this advisory automatically reduces the pressure setpoint to allow the motor to cool.  To avoid this advisory, run the system at a lower duty cycle or with a smaller mix chamber.
