Commissioning
Please read this manual in its entirety before attempting to install or operate your MXA actuator. A full understanding of
the installation and operation options will assist you in installing the actuator in the most effective manner. Limitorque
has designed the MXA actuator for long life even in the harshest environments. Flexible control and protection options
are provided to ensure the actuator meets your requirements.
a CAUTION: Refer to the Instruction, Operation and Maintenance [IOM] manual for Limitorque MX Electronic
Actuator, LMENIM2306.
The latest version of the IOM can be found on the Flowserve website at www.flowserve.com.
9.1 Internal Access Only via Terminal Compartment
To install and commission the actuator, only the terminal compartment cover needs to be removed. Operating configu-
ration can be performed without direct access to the internal electronic circuit boards.
a CAUTION: Disconnect all incoming power before opening any cover on the actuator. The user/operator must ensure
that safe working practices are employed at all times and are in accordance with local or national standards that are
enforced at the particular site.
a CAUTION: Removal of any cover, other than the terminal compartment cover, will invalidate the unit warranty.
Exposure of actuator components to an environment that results in deterioration of internal components will also
invalidate the unit’s warranty.
9.2 Conduits and Unused Conduit Entries to be Sealed
During final field installation, ensure that all cable entries are correctly sealed in accordance with national standards or
regulatory authorities. All temporary transit plugs must be removed and any unused cable entries closed in an approved
manner.
9.3 Cable and Wire Routing
Power and signal wiring need to be routed through separate conduit or raceways.
Flowserve strongly recommends remote communication wiring be routed separately from line power wiring.
Specifically, instrumentation wiring, including communication, analog and discrete signal signals, should be routed in
conduits or raceways that are separate from power wiring. Flowserve cannot guarantee the reliability of instrumentation
signaling if this recommendation is not implemented.
