1.0 Introduction
1.1 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.
1.2 Purpose
This specification is designed to complement the TS4000H Instruction Manual by providing a
complete description of this field device from a HART Communications perspective. This
specification is designed to be a technical reference for HART capable host application
developers, system integrators, and knowledgeable end users.

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.
3.1 Getting Started
In order to enable HART communication with the TS4000H detector, users may employ several
means including HART handheld communicators or PC-based systems. Using a PC-based
software application and a HART interface modem, for example, allow operators to access
information from the TS4000H. A typical setup is illustrated in Figure 1.

Figure 1: Connecting a PC to a HART device
Once the detector is installed (see TS4000H Instruction Manual) and connected to a PC, host
application, or handheld terminal, the master will commonly begin communication to
the TS4000H by using the HART Command #0. The field device will then respond only if its
tag matches. The data in the reply to Command #11 is identical to that of Command #0, so the
master can then construct the Unique Identifier for use with further commands.
NOTE: The handheld device allows for the retrieval of diagnostic information and input of
device settings as needed and should not be used as a permanent part of a safety
system.

4.0 Product Interfaces
4.1 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. Analog signal (4-20 mA) and relays
provide remote and/or discrete indications of the sensor’s operation.
4.2 Host Interface
The HART interface uses the 4 – 20 mA current loop. Refer to the installation manual for
connection details.
4.2.1 Analog Output: TS4000H Mode
The primary variable is proportional to the part per million. 4.0 mA output current corresponds
to 0 ppm. 20.0 mA output current corresponds to 100 ppm or 100% of full scale.
4.3 Local Interfaces, Jumpers, and Switches
4.3.1 Local Controls And Displays
Refer to the Installation Manual for connection details.
4.3.2 Internal Jumpers And Switches
Refer to the Installation Manual for connection details.
5.0 Device Variables
There are no device variables exposed to the user.
6.0 Dynamic Variables
There is only one Dynamic Variable exposed to the user.
6.1 Primary Variable = Part Per Million
The primary variable is proportional to the part per million 4.0 mA output current corresponds to
0 ppm. 20.0 mA output current corresponds to 100 ppm or 100% of full scale. The device mode
is the variable, which corresponds to the Modbus register 0x00.
6.2 Secondary, Tertiary, and Quaternary Variables: Not Applicable
There are none defined for the TS4000H product.
