Introduction
1.1 Purpose
This manual explains how to install and operate the Flowserve Limitorque MX™/DDC-100 field unit and is to be used
as an addendum to Bulletin FCD LMENIM2306, MX Electronic Actuator Installation and Operation Manual. Up to 250
actuators, each containing a DDC-100 field unit, may be connected by a single twisted-pair cable to form a DDC-100
network. This network permits the actuators to be operated by various control room devices such as a distributed

communicates status and alarm data from each MX and valve.
