1. PRODUCT DESCRIPTION 1.1 GENERAL The Model 5100-XX-IT Toxics Gas Sensor Module is a member of the Information Technology ”IT” family of gas sensor transmitter modules.
accessible from the cover plate as illustrated in Figure 3-1. Figure 3-6 in this manual provides the wiring terminations for connections to the Sentry controller. When the module is operated in conjunction with a Sentry controller, the alarms outputs in the module can both be set to “Sentry”, allowing the Sentry controller to manage alarm acknowledge and reset rather than the sensor module.

Connectors for wiring for power, signal interface and alarm relays are located on the interface board assembly 1.4.9 SENSOR ASSEMBLY The sensor assembly includes an explosion proof housing containing the gas sensor and a wiring harness for connection to the transmitter.
2. CAUTIONS & WARNINGS 2.1 INTRODUCTION Although IT Transmitter Modules are designed and constructed for installation and operation in industrial applications including "hostile" environments, caution should be taken to insure that the installation is made in compliance with this instruction manual and that certain procedures and conditions are avoided. This chapter discusses the necessary cautions. Read the entire chapter prior to installation of the equipment. 2.

3. INSTALLATION NOTE All IT modules are factory are pre-configured and calibrated. All modules are tagged to indicate the configuration including the sensor module number. Identify all components during unpacking and install using the factory configuration. 3.1 SENSOR MODULE LOCATIONS Select locations for each sensor modules based on the following: • Modules should be placed close to the potential source of gas. • Modules should be placed in areas accessible for calibration.
NOTES The drain wire of shielded cable must NOT be used as one of the conductors. Installation and wiring must be in accordance with the National Electrical Code. Temperature o rating of cable wire must be at least 75 C. If cable runs through higher temperature environments, it must be specified for that environment. 3.3 ENCLOSURE INSTALLATION To protect the transmitter and sensor assembly they should be removed from the enclosure and preserved until final installation and wiring termination.
6. Carefully return the transmitter to the enclosure installing it over the two stand-off’s. Tighten the retaining screws into the stand-offs.
3.5 MODULE ADDRESS SWITCH For digital interface applications the module address switch (or Modbus node) must be set per Table 3-2: POSITION ADDRESS POSITION ADDRESS 1 Sensor 1 9 Sensor 09 2 Sensor 2 A Sensor 10 3 Sensor 3 B Sensor 11 4 Sensor 4 C Sensor 12 5 Sensor 5 D Sensor 13 6 Sensor 6 E Sensor 14 7 Sensor 7 F Sensor 15 8 Sensor 8 0 Software Menu Table 3-2 Sensor Module Address Switch Positions NOTE For Sentry applications only sensor addresses 1-8 are allowed.

4. OPERATION 4.1 INTRODUCTION – HUMAN-MACHINE INTERFACE SYSTEM The Gas Sensor Module utilizes a visual menu system operated by means of a magnet. A magnetic tool (5358-50) is supplied for this purpose. The menu system is used to configure alarm set-points, calibrate the sensor module, and for maintenance procedures and alarms acknowledge. 4.2 HUMAN-MACHINE INTERFACE The module menu system is operated by means of directing the magnet stick toward each of four independent hall-effect magnetic switches.
4.3 MAIN MENU Table 4-1 describes the primary man-machine interface operation.
