Encoder Replacement Kit 24U938

Overview

The E-Flo DC uses the encoder for two purposes:
• The encoder informs the control board where the
motor is in its mechanical rotation and uses that
information to properly control the motor torque.
• The encoder controls stroke length by allowing the
control board to count the number of complete
motor rotations.

Tools Required

• 6 mm hex wrench
• .050 in hex wrench
• Phillips screwdriver (#1)
• Torque wrench 15 ft-lb (20 N•m)
• Blue (medium) thread locking compound
