E99 : Loss of Communication

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

Check all wiring between the display and the corresponding control board.

  • Pay close attention to the wire crimping on plug J13 for each display and motor control boards. And J5/DISPLAY C of temperature control module.
  • Swap the J13 plugs from one display to the other
  • If E99 remains on the same display, replace the Display
  • If E99 moves to other display then reverse the J13 on motor control with J5/DISPLAY C of temperature control module to determine if cable or lower control is the cause.
