Wiring
All internal wiring is flame resistant, rated -40°C to 105°C (-40°F to 221°F), and is UL listed.•
Valve interface
Mounting base conforms to MSS SP-102 or ISO 5210 as required. Steel torque bushings (type B) •
and bronze thrust nuts (type A) are removable for machining.
Design life & endurance
Design Life - One million drive sleeve turns is considered typical life expectancy under normal •
operating conditions in approved ambient working environments.
Endurance – 50 million collective drive sleeve turns of endurance testing were performed on the •
MX for proof of design.
AWWA C540-02 – “Standard For Power Actuating Devices For Valves and Sluice Gates” – 5,000 •
cycles with confirmation of specified torque and position repeatability.
Diagnostic features
Diagnostic facilities are displayed on the LCD by accessing the diagnostic menu or the MX
Dashboard
™
. It includes: motor data (voltage, current, phase rotation, and temperature), hardware
status, and identification (tag, serial order, and software revision), torque profile (comparison of
last torque to baseline), and operations log (total turns, contactor operations, valve stroke time, and
handwheel operations). Diagnostics also includes a restricted Frequency Domain Analysis (FDA)
feature. The FDA methodology captures torque, position or speed values at regular time intervals
while the actuator is motoring, and calculates the resulting data set with a Fast Fourier Transform
(FFT). The resulting information can be used to isolate any components in the mechanical drive
train that may exhibit excessive wear or may effect normal actuator operation. FDA and resultant
fault indications can be displayed via the graphical LCD. The actuator also contains the ability for
diagnostics information to be downloaded to a PC or PDA via both IRDA and optional Bluetooth ports
utilizing MX Dashboard.
Factory test
Factory testing verifies rated output torque, output speed, motor performance, handwheel opera-
tion, local control, control power supply, control features, and baseline FDA. A report confirming
successful completion of testing is included within the actuator.
Conduit entries
Three threaded conduit entries are provided tapped: 1 x 1½" and 2 x 1¼" NPT. The actuator is avail-
able with 1 x M40 and 2 x M25 metric to BS3643, and PG adapters are available upon request.
