2.0 Product Overview
2.1 General Description
The TS4000 is a +24VDC-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 TS4000 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 TS4000 is certified as explosion proof with intrinsically safe outputs 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 TS4000
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.
2.3 Applications
The TS4000 Intelligent Sensor provides toxic gas detection for a wide range of applications,
including, but not limited to the following:
