  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.

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

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 sensors
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 HVS4000s
microprocessor then produces a linear 4-20mA
output signal.

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

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.

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.

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.

Model S4000T Intelligent Sensors are positioned

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/Ts can all be used for these
applications.

Landfill Vapor Recovery
Landfills produce Methane and H2S gas generated
from decomposing materials. The recovered methane
is used to fuel compressors, engines and
co-generation plants. These facilities provide
an excellent opportunity for Model S4000C
Intelligent Sensors to detect the methane gas.

Cogeneration

• 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

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 thats 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
•
