1.0 Introduction Scope The TS4000H HART toxic gas detector complies with HART Protocol Revision 6.0. This document specifies all of the device specific features and documents HART Protocol implementation details. The functionality of this Field Device is described sufficiently to allow its proper application in a process and its complete support in HART capable Host Applications.
TS4000H HART 3.0 Product Overview The TS4000H is an intelligent sensor for the detection of toxic gas and vapors. The microprocessor-based electronics processes information at the sensor site, within an explosion- proof housing. The TS4000H accurately measures toxic gas and reports the measurement as a parts per million (ppm) of the gas.
TS4000H HART 4.0 Product Interfaces Process Interface This section describes all interfaces between the devices and the measured process. 4.1.1 Sensor Input Channels A digital display provides indications and display codes that can be viewed through a window in the cover. A red LED above the digital display signifies an ALARM condition, while a red LED below the digital display signifies a WARN condition.
