Chapter 1. Introduction Analog Input A D C Analog Engine Analog Mode Optional 4/0-20 mA Generator Current Output Digital Engine Digital Mode Microprocessor RS-422/485 Interface Serial Figure 1-2. Block Diagram of STX Operation When the STX is installed in or serially communicating with an MVS, the MVS display shows monitoring information from the STX. In these configurations, the system is referred to as the MVS-STX. The MVS keyboard is used to access functions during operation and to input parameters during setup and calibration. The MVS’s optional PCBs — Current Output, Relay Output, MVS-RIO, etc. — can be used to further process the STX’s digital output. Functional Description Analog vs. Digital Mode Figure 1-2 illustrates STX operation. The STX can receive an analog signal from K-M half bridge sensors/transducers (L-Cell, Microcell, Load Stand II, Load Disc II, or Load Link I/II) or from full bridge sensors/transducers. The STX has two modes of operation: • Analog Mode — The analog engine is calibrated using SW1 (Up Key), SW2 (Down Key), and SW3 (Span/Zero slide switch). When in Analog Mode, current output (0-20 or 4-20 mA) from the STX PCB is controlled by the analog engine. • Digital Mode — The digital engine is calibrated with commands through the RS-422/485 serial port or through the MVS, as applicable. When in Digital Mode, current output (0-20 or 4-20 mA) from the STX PCB is controlled by the digital engine. It is possible to have two calibrations operating simultaneously. For example, the STX can be in Analog Mode (with current output from the STX PCB controlled by the analog engine). But, at the same time, the STX can be calibrated digitally through the serial port, with displayed engineering units and setpoints, additional current outputs, etc. controlled by the digital calibration. Note You must calibrate the STX digitally if the STX is serially connected to another device, even if you have already done an analog calibration. Filters and Tracking The STX has several features which help provide stable output: • The Sentry DSP Filter reduces output changes that can result from vibration. • Material and zero tracking functions reject sensor drift and other related longterm errors while preserving the output’s stability and accuracy. LEDs The STX PCB has three LEDs: Status, Transmit (TX), and Receive (RX). 1-2
Chapter 1. Introduction Status LED The Status LED functions as follows: • Material/zero tracking disabled — The LED toggles at every A/D conversion, serial communication, or communication with the MVS microprocessor, as applicable. • Material/zero tracking enabled — If material in the vessel is in motion (rate of change is greater than threshold rate), the LED toggles at every A/D conversion, serial communication, or communication with the MVS microprocessor, as applicable. If material in the vessel is stable (rate of change is less than threshold rate), the LED remains on and does not toggle. Note See Chapter 3, Stand-Alone STX Analog Calibration and Setup, or Chapter 8, MVS-STX Service Menu, for details on material/zero tracking. Transmit (TX) LED and Receive (RX) LED The Transmit and Receive LEDs toggle when communicating with a serial device to reflect an incoming request (RX) from a host and the response (TX) from the slave. Manual Contents A brief description of the key sections of the manual follows: Note If calibrating or setting up the STX through an Allen-Bradley PLC or Modbus PLC, also refer to the applicable PLC manual — KM-RIO Installation and Operation Manual, MVS-RIO Installation and Operation Manual, or MVS-Modbus Installation and Operation Manual. Manual Conventions Three kinds of special explanations appear throughout the manual — WARNING, CAUTION, and Note. The format and significance of each is defined below: WARNING Possible danger to people. Injury may result if this information is ignored. CAUTION Possible risk to the product. The signal processor or other equipment may be damaged if this information is ignored. Note Contains additional information about a step or feature critical to the installation or operation of the signal processor. • Chapter 2 — Hardware Installation • Chapter 3 — Analog Calibration and Setup of the Stand-Alone STX • Chapters 4 through 9 — Digital Calibration and Setup of the MVS-STX (STX serially connected to an MVS or installed in the MVS) • Appendix B — Digital Calibration of the STX serially connected to a PLC or K-M ROPE System 1-3
