2.0 Product Overview
2.1 General Description
The TS4000H is a +24 VDC-powered toxic gas detector comprised of a Base Unit, Interface
Module, and Electrochemical Cell (sensor) – refer to Sections 2.4, 2.5, and 2.6, respectively, for
more information. The TS4000H supports a wide range of General Monitors’ approved
electrochemical cells, and operates as a universal toxic gas detector by simply replacing and
calibrating sensors. The microprocessor-based electronics of the Interface Module process
information at the sensor site and communicate detected gas values to the Base Unit for data
control and display.
The TS4000H Base Unit is certified as explosion proof and the Interface Module as intrinsically
safe for use in hazardous locations. It can also be used for general-purpose, non-hazardous
applications.
2.2 Features and Benefits
Microprocessor-Based Electronics
: Monitors fault conditions, processes input signals from
the electrochemical cell, and provides outputs in the form of display codes and analog / digital
signals.
One Person Adjustment-Free Calibration
: Using a magnet to initiate the calibration
sequence, apply the gas, and wait for the display to indicate that the unit has completed the
calibration. No user adjustments are required.
Three Digit, Seven Segment LED
: Indicates gas presence, operational modes, fault codes
and calibration cues.
Two Discrete LED Indicators
: Indicates alarm and warning conditions.
4-20 mA Analog Output
: Transmits fault, calibration, and gas concentration levels to a remote
display, computer, or other device such as an alarm, dispensing device, or master controller.
Dual Redundant Modbus RS-485 User Interface
:
Provides the ability to operate the
TS4000H remotely, using 2 redundant channels. This interface allows the user to remotely
change the alarm and warning relay settings, clear selected faults, issue calibration requests,
enable gas check, issue end / abort commands, clear error counters, change baud rates, and
change formats for serial communication lines.
HART User Interface
:
Provides the ability to operate the TS4000H remotely, using two-way
communication protocol. This interface allows the user to remotely change the alarm and
warning relay settings, read/clear logged events, issue calibration and gas check requests,
issue end / abort commands, and many more. For more details on HART commands, refer to
the TS4000H HART Communication Manual.
