    摘要: Embodiments of a valve positioner (100) that can maintain operation of the control valve (102) despite failures in one or more components. These embodiments reduce downtime by allowing in-situ repair to occur on the valve positioner. In one embodiment, the valve positioner incorporates a by-pass component (120), which can utilize control input signals (e.g., a 4-20 mA signal) to energize one or more components (e.g., a current-to-pressure converter) to cause the control valve to modulate fluid flow without the digital microprocessor and/or related components.

    摘要: An interactive computer-controlled management system for real-time data gathering and analysis of process information relating to a plurality of data sources in a facility and for controlling process functions of the data sources. In a preferred embodiment, the data sources include gas cabinet panels and related process equipment typically found in a wafer fab facility. The system operates in a distributed processor environment and includes a host processor having graphic, control and user interfaces and a multi-ported processor networked to the host processor. The multi-ported process includes protocol sensitive hardware interfaces for communication with the programmable logic controllers of each particular data source. The multi-ported processor also includes software means for emulating a common protocol such that each gas cabinet or other connected device appears to the host processor as an address location in a memory of the multi-ported processor. The address locations are sequentially polled by the host for updated status, alarm and set point information which is displayable at the host terminal. The functions of the management system are divided into three primary information management and monitoring areas including alarm management, map functions and administrative functions. The alarm management functions permit acknowledgement of alarms and retrieval of updated alarm information. The map functions provide specific information about gas cabinets and other components within the facility. The administrative functions control basic system operation such as access, report generation and shut down procedures.

    摘要: Opening and closing mechanism which is comprised of the following:
    - A power supply (1)
    - A rotation direction setter (2)
    - A control unit (3) which is connected to the rotation direction setter (2)
    - A valve actuator motor (5) which is connected to the control unit in which one of the connections is for sending a BREAK instruction from the control unit (3) to the motor (5), a signal which is sent when a shutdown occurs due to over-torque inferred from the motor rotation speed.
    This opening and closing mechanism is not limited by any wear of the plug, has no need to use measurement of the current drawn and establishes the torque level based on measurement of the motor rotation speed, the rotation speed corresponding to the nominal torque having been previously established.
