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
Base Unit
Interface
Module
EC Cell
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
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

Barrier
Gas Enters Through
Permeable Membrane
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.

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

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
HVS4000
is now
calibrated andfault
the new sensor SPAN values (or calibration constants)

are stored in the non-volatile memory (EEPROM)
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.
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.
