DESCRIPTION
This bulletin describes the installation and operating instructions for the FX04 and FX04-1, 3 lb.-ft./
4Nm servo motors. .
SAFETY INFORMATION
WARNING: When this equipment is mounted onto an appliance, all external timers/control-
lers must be listed or recognized components and approved by national certification agencies
for the purpose for which they are used and approved for use by a local authority who has
jurisdiction.
The Fireye FX04 and FX04-1 servo motors are precision actuators designed to accurately position
valves and dampers. The servomotor interprets Modbus commands from an external control and
uses a stepper motor to drive to the commanded position. A feedback potentiometer provides contin-
uous positional information that can be read and cross checked by the external control.
The FX04 series servo motor offers a maximum output torque of 3lb.ft/ 4Nm with a minimum travel
time of 30 seconds for 90 degrees of rotation. Maximum rotation angle of the drive shaft is 100
degrees.
The servo is designed to be applied for fuel valves and air damper control on industrial burners. It
can also be applied to drive any type of flow control valve or damper as long as the output torque is
suited to the application.

  • Page 3 ® The installer should be satisfied that, as a result of the mounting, the commissioning or as a result of the test adjustments on the actuator, no potential hazards will be produced for devices/machines/ plant. Before mounting the servo motor, check the free movement of the valve/device. After completing the mounting and adjustment, check the correct functioning of the servo motor.
  • Page 4: Installation

     INSTALLATION Fasten the FX04 servo motor using bolts through a suitable mounting into the four 3/16 inch/5mm mounting holes so that the mounting surface rests flat. The output drive shaft should be connected using a suitable arm, link or flexible coupling. The mounting position of the FX04 servo motor is arbitrary.
