Electric multi-turn actuators - AUMA - #39

Text version of the page

[1] Failure Due to functionality failures within the actuator or the peripherals, the actuator might not be controlled from the control room. [1] [2] [2] Function check Due to ongoing work on the actuator, the device cannot be controlled from the control room at that specific time. [3] Out of specification Deviations from the permissible application conditions determined by the actuator itself through self-monitoring. The actuator can still be controlled from the control room. [3] [4] [4] Maintenance required The actuator can still be controlled from the control room. The device must be inspected by a device specialist to avoid any unscheduled downtime. Application in accordance with NAMUR NE 107 The aim of this recommendation is to achieve a uniform and simple communication vehicle between the devices and the plant operator. Actuators classify internal status signals in compliance with the NAMUR recommendation. Exact diagnosis is performed when evaluating the device data. features Monitoring the life cycle factors Torque characteristics Apart from the valve torque requirement and the operating cycles, device temperatures are further decisive factors for the device life cycle. As an option, the actuators can be equipped with sensors continuously monitoring motor temperature, gearing temperature, electronics environmental temperature as well as vibration. The AC is capable of recording torque characteristics at different times. When comparing a current curve and a reference curve, conclusions can be drawn on the valve states. Time-stamped event report/ operating data logging Setting procedures, switching procedures, alarms, faults and operation times are recorded within the time-stamped event report. The event reports is a distinct component of the diagnostic feature of the AC. Plant Asset Management Due to extensive diagnostic features and the classification of status signals in compliance with NAMUR, AUMA actuators with integral controls AC 01.2. meet the requirements for integration into plants managed by this type of system. | 39
