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

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

32. Digester Gas Monitoring Ground Flare Methane (CH4) gas generated from anaerobic digesters also contains hydrogen sulfide (H2S) resulting from decomposing sludge. The H2S gas is usually removed. Methane gas is used to fuel compressors, boilers and engines. Any unused gas is then flared off to the atmosphere. Applications exist for Models S4000C/T and IR2100 Infrared Point Gas Detector because of high O2. The Model IR5000 is also used for CH4 detection in large waste treatment plants. S4000C Gas Detector Sludge Digester Tank Sludge Gas Flowmeter

33. Sludge Dewatering De-watering System Incoming sludge from waste treatment facilities contains hydrogen sulfide and methane gas. The sludge is transported through a spiral conveyor into the de-watering system where the water is removed. The outgoing conveyor transports the remaining solids to an incinerator. Model S4000T Intelligent Sensors are positioned so that during operation of the compressor any escaping H2S will be detected. Outgoing Sludge to Incinerator Incoming Sludge Model S4000T Intelligent Sensors are positioned both sides of the compressor

34. Wet/Dry Wells & Lift Stations Wet wells and dry wells are confined spaces which can develop a build-up of H2S and CH4. This gas concentration can become explosive and/or toxic to the level of personnel danger. Because personnel are required to service these areas, O2 deficiency monitors are installed to ensure that oxygen levels do not drop below the regulated levels needed to sustain life. Models HVS4000 / HVS400 and S4000C/T’s can all be used for these applications. S4000C/T and HVS4000 Manhole Sewer or Vault

37. Many sewage treatment facilities use Methane generated from digesters to power electrical generating plants. This power is used to run the facilities as a supplement to purchased power from utility companies. Model S4000C Intelligent Sensors are used to monitor leaks in the co-generation building Cogeneration S4000C Gas Detector

38. Selling against the Competition • Fixed Gas Detector Competitors typically found in the Water & Wastewater Industry are: • ATI • Capital Controls • Foxcroft • Regal • MSA • US Filter • Advantages of HVS4000 and HVS400 are: • HVS400 is small and compact by design with a 4-20mA signal that can be used as the “front-end” sensor for a SCADA system directly • HVS400 2-wire self contained transmitter with sealed electronics is very suitable for corrosive chlorine service • Calibration prompts can be viewed on the LED window, without the added expense of a transmitter housing with a display

39. Selling against the Competition • End-users have reported that the HVS400/4000 is rugged and looks more like an industrial product than competitors… such as “Foxcroft, Capital or Regal”… who more closely resemble “Swimming Pool Type” chlorine detectors • Most Cl2, SO2, H2S applications do not require a XP rated enclosure, however that’s all many competitors have to offer. The general-purpose enclosure on HVS400 sensors, will keep system cost down • End-users like the “potted & sealed” HVS400 electronics because corrosive gases cannot access the PC board components • Galvanic isolation on the HVS4000 allows hot swapping of sensors and remaining sensor life, reduces downtime by providing a “heads-up” on sensor life • Dual redundant MODBUS RS485 interface provides remote operation of all functions
