Replacing a Servomotor and Related Components
If it is determined that a servomotor needs replacement or you are experiencing
reliability issues with the servomotor assembly, Fulton recommends installing
a Siemens Servo Gas and Butter y Valve Assembly. This assembly includes the
gas butter y valve, bracket, coupling and servo assembly. Replacing this entire
assembly may not be appropriate for all applications, thus the servo motors
are available individually as well. The installing technician must verify that the
bracket allows for proper alignment and that the coupling to shaft connections
are secured adequately.
If it is determined that a servomotor needs replacement, adhere to the following:
1. Verify the model number of the new servomotor is the same as the
old servo motor. The model number starts with the letters SQM and is
displayed on a label on the side of the motor. Proceed only after model
number is veri ed.
2. Turn power to the boiler o .
3. Turn o all electricity to the boiler.
4. Remove the cover on the servomotor to be changed.
5. Remove the green wiring plugs and the conduit termination point from
the motor by pulling them towards you. A black grounding wire runs from
the motor to the conduit termination point. Pull it o from the conduit
