Servo-Motor Installation
Fireye NX04, NX20 and NX50 Servo-Motors are available in 3 ft. lbs (4 Nm), 15 ft. lbs (20Nm) and
37 ft. lbs (50 Nm) versions. The accuracy of the final setup is contingent on the proper application of
the motor to the controlled element. Extreme care should be given to the secure mounting of the
Motor to the Air Damper or Fuel Valve being controlled. The Servo-Motor MUST provide
permanent connection to the controlled element to provide safe, reliable and repeatable operation.
