Quick Start
Quick Start provides step-by-step instructions for commissioning each MX actuator. This information is also available in
Bulletin LMENIM2310, Quick Start-Up Instructions. These instructions are for the following:
• Position limits calibration – can be performed one of two ways:
1. Electrical operation: See Section 2.1.2, Electrical Operation Feature.
2. Handwheel operation: See Section 2.1.3, Handwheel Operation Feature.
• DDC operation: See Section 2.2, DDC Option.
• FF operation: See Section 4.10, FF Option.
• PB operation: See Section 4.11, PB Option.
• DeviceNet operation: See Section 4.12. DN Option.
When these Quick Start instructions are complete, the position limits will be set and the actuator will be ready for
normal operation.
NOTE: The actuator has been configured with all customer-specified parameters and no further calibration should be
necessary. If full valve data was not provided when ordering, or if changes are needed for parameters, see Sections 3.5
and 6, Commissioning the Actuator and Customizing the Actuator.
2.1 Calibrate – Position Limits
1. Install the MX actuator on the valve.
2. Refer to the nameplate for the correct main power supply voltage. Switch on the main power to the unit.
3. Turn the red knob to the STOP position. The “SET CLOSE POSITION LIMIT” message will be displayed. When the
red knob is in “LOCAL” or “REMOTE,” the liquid crystal display (LCD) screen will read “SET POSITION LIMITS.”
4. Calibrate end position limits one of two ways:
• Electrically, using the control panel. See Section 2.1.2, Electrical Operation Feature.
• Manually, using the handwheel. See Section 2.1.3, Handwheel Operation Feature.
Once the position limits have been set, the screen message will indicate the valve position as a percentage of the valve
opening.
While setting limit switches, place the red selector knob in the “LOCAL” position to permit the actuator to run open or
closed in push-to-run mode (inching) only.
a CAUTION: Extreme care must be taken as the valve approaches its end position.
The unit will not function with the red selector knob in the “REMOTE” position until both limit switches are set.
