  1. Introducing… HVS4000 & HVS400 Toxic Gas Detectors from Halogen Valve Systems

  2. Agenda • Introduction to General Monitors • HVS4000 • HVS400 • Features & Benefits • Specifications • Calibration • Accessories • Applications • Competition • Closed Loop Marketing • Feedback/Questions PRODUCT LAUNCH

  3. General Monitors • Established in 1961 by Dr. Frank Linville • Two Manufacturing facilities and R&D Sites - Lake Forest, CA and Ireland • The Best Service & Customer Support • World Class Automated Manufacturing • Total Quality Management • JIT Purchasing • ISO-9001:2000 Status • Worldwide Distribution Channels • Advanced Proprietary Technologies for Catalytic Bead, Metal Oxide Semiconductor, Electro-chemical & Point and Open Path Infrared

  4. HVS4000 at a Glance • The HVS4000 is a +24VDC powered toxic gas detector comprised of a base unit, interface module (IM) and electrochemical cell • Galvanically isolated intrinsically safe design of the (IM) module supports sensor field replacement without the need for special tools or hot work permits • Complements our HVS400 Series products and provides a “Total Toxic Solution” for application in Chlorine rooms. Base Unit Interface Module EC Cell

  5. Interface Module • The HVS4000 Interface Module (IM) is encapsulated in an anodized aluminum housing enabling sensor information to be processed at the point of detection. The HVS4000 provides a 4-20mA output signal proportional to the gas concentration at the Base Unit • IM Features: • Galvanically isolated Intrinsic Safety Barrier to the internal electronics of the IM • Electrical conditioning circuitry for the electrochemical cell • Mechanical and electrical interface for the electrochemical cell • Explosion proof conduit seal from the Base Unit to the IM • Explosion proof housing for the Intrinsic Safety Barrier • One I/O pair for digital serial communication to and from the Base Unit and IM • One +24VDC / COM GND pair for power into the Interface Module

  6. Base Unit • The HVS4000 Base Unit provides the display / control device for the entire HVS4000. The Base Unit is based on the proven Intelligent Sensor platform • Base Unit Features: • Bright LED Digital Display (outdoor readable) • MODBUS Communications • High Rating Relays • One Activation Point for Settings/Calibration • Simplified Wiring and Field Connections • Standard Platform Calibration Prompts • Remote Sensor Placement Capability • Remaining Sensor Life Indicator • Low Total Cost of Ownership

  7. 4-20mA/Modbus Electrolyte Reservoir Counter Electrode Sensing Electrode O-Ring Seal Gas Permeable Membrane Gas Enters Through Permeable Membrane Gaseous Diffusion Barrier Detection Method TS4000 Electronics Target gas diffuses through the diffusion barrier limiting the amount of gas entering the sensor. It then diffuses through the gas permeable membrane until it reaches the sensing electrode that produces ions. The REFERENCE electrode provides voltage stability for the sensing electrode, and the electrodes (sensing and reference) are constructed of materials specific to the target gas. This specificity creates the ion flow current central to the sensor’s detection method. The HVS4000 integral electronics provides temperature compensation, and the amount of ions produced by the target gas molecules striking the sensing electrode, is proportional to gas concentrations. The HVS4000’s microprocessor then produces a linear 4-20mA output signal. Reference Electrode

  8. Available Gases • Ammonia 0-50, 0-100 ppm • Carbon Monoxide 0-100, 0-500 ppm • Chlorine 0-10 ppm, 0-20 ppm • Chlorine Dioxide 0-3 ppm • Ozone 0-1 ppm • Oxygen 0-25% by Volume • Sulfur Dioxide 0-20 ppm

  9. Key Features & 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 • Three 8A rated Relays: Warning, Alarm and Fault • Remote Mounting of Interface Module: Provides application flexibility • 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

  14. Simple Calibration • Apply and hold the magnet over the HVS logo on the cover of the Base Unit. Wait until AC appears in the display window. Remove the magnet to select AC. The unit is now in Calibration Mode. • The display flashes the Remaining Sensor Life. The user can choose to reset or not to reset the sensor life at this point. • The Remaining Sensor Life flashes while the unit is being set to zero. Once the unit has been set to zero gAS appears in the display window • Apply the calibration gas concentration to the sensor (50% FS of the required range of detected gas). The display changes from gAS (apply gas) to CP (Calibration in Progress) indicating that the sensor is responding to the calibration gas. While the unit is reading the gas concentration, the menu is disabled • After three to five minutes, the display changes from CP to CC indicating that the calibration is complete • Remove the gas and wait for the unit to return to normal operation. The display may indicate a few percent FS and will eventually drop to 0. If a unit time out occurs the user receives a calibration fault The HVS4000 is now calibrated and the new sensor SPAN values (or calibration constants) are stored in the non-volatile memory (EEPROM)

  15. Changing a Sensor • Each spare sensor is shipped in a plastic bottle. DO NOT remove the sensor until you are ready to apply power to the system. To ensure proper sensor response, each HVS4000 must be calibrated in the field upon initial installation • If the new sensor is in a plastic storage container, then remove the lid ring and uncap the jar. Remove the sensor from the container Save the storage container for later use.

  16. Changing a Sensor • Note: Certain types of sensors are shipped with a shorting wire across two (2) pins. This wire must be removed prior to installing in the HVS4000. Ammonia (NH3) sensors are shipped attached to a small circuit board with a battery. Remove the battery board prior to installing in the HVS4000. • Save both the shorting wire and/or battery board for later use. Shorting Wire Battery Board
