Limitorque MX - Acrodyne

MX SpecificationsThe MX is the most rigorously tested non-intrusive actuatorin the industry and complies with all pertinent global requirements.Please contact the factory should your requirementsexceed the listed parameters.Global certificationsStandard Non-hazardous certifications - The normaloperating temperature range for weatherproof applications isfrom -30°C to +70°C (-22°F to +158°F). Options are availableto -50°C (-57°F).• FM – NEMA 3, 4, 4X and 6.• CSA – Type 3, 4, and 6.• IEC – IP 68 to 15 m for 96 hours.• Submersion – NEMA 6 (6 ft–30 min), IEC529, IP68 (15m–96 h), Limitorque specification (20 ft–24 h)• Saliferous (Salt) spray – 1500-hour test per ASTM B117-1985.Standard Explosionproof certifications - The normal operatingtemperature range for explosionproof applications isfrom -30°C to +65°C (-22°F to +149°F). Options are availableto -50°C (-57°F) for FM and CSA.• FM – Class 1, Division 1, Group B, C, and D. Class II/III,Division 1, Group E, F, and G – T4• CSA – Class 1, Division 1, Group C and D.

Steel torque bushings (type B) and bronzethrust nuts (type A) are removable for machining. Refer torating chart on page 10 for a listing of couplings available.Design life & endurance• Design Life - One million drive sleeve turns is consideredtypical life expectancy under normal operating conditions inapproved ambient working environments.• Endurance – 50 million collective drive sleeve turns ofendurance testing were performed on the MX for proof ofdesign.• AWWA C540-02 – “Standard For Power ActuatingDevices For Valves and Sluice Gates” – 5,000 cycles withconfirmation of specified torque and position accuracy.Diagnostic featuresDiagnostic facilities are displayed on the LCD by accessingthe 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 oflast torque to baseline), and operations log (total turns,contactor operations, valve stroke time, and handwheeloperations). Diagnostics also includes a Frequency DomainAnalysis (FDA) feature. The FDA methodology capturestorque, position or speed values at regular time intervalswhile the actuator is motoring, and calculates the resultingdata set with a Fast Fourier Transform (FFT). The resultinginformation can be used to isolate any components in themechanical drive train that may exhibit excessive wear ormay effect normal actuator operation. FDA and resultantfault indications can be displayed via the graphical LCD. Theactuator also contains the ability for diagnostics informationto be downloaded to a PC or PDA via both IRDA andBluetooth ports utilizing MX Dashboard.18
