MX Electronic Actuator

FCD LMENIM2306-00 – 08/05

Before You Begin

The MX actuator’s 32-character LCD display provides easy-to-read
actuator status, diagnostics, and setup information—in the language you
choose. Once you have set the actuator’s position limits, the unit will be
ready for normal operation. The screen message will indicate the valve
position as a percentage of the valve opening. Full open is expressed as
100% OPEN and full close is expressed as 0% OPEN.

Factory Settings

The MX actuator can be configured with the parameters that you require in
the field. The calibration of position limits are addressed in this document.
If full valve data was not provided when ordering, or if changes to the
default settings are needed, see Bulletin LMENIM2306, Installation and
Operation for MX-05 through MX-140, for complete instructions.

Checking the Open/Closed Settings

Valve Closed As you close the valve using the actuator, make
sure that the close light (green) illuminates just as the travel limit is
reached. The display should read 0% OPEN.

•

Valve Open As you open the valve using the actuator, make sure that
the open light (red) illuminates just as the travel limit is reached. The
