VISION™ 8 Operating Manual
Chapter 1 – Overview
1.1 Introduction
The VISION™ 8 from DOD Technologies simultaneously monitors up to eight locations (or points ) for targeted
toxic and corrosive gases. The system is comprised of an individual 'analyzer' that monitors up to eight points.
It responds to gases that exceed a programmed alarm level by:
• Triggering visual alarms that warn of high or low concentrations
• Triggering relays or activating analog outputs to external devices
• Displaying the point number, gas type, and gas concentration
• Recording the alarm information and storing it in memory
The VISION 8 triggers outputs for each individual point at two levels of gas concentrations. These
programmable limits are factory-set at 1 TLV and 2 TLV for their respective gases. Each sample point may
range up to 500 feet from where the VISION 8 is positioned. This allows operators to monitor gas
concentrations in locations away from where gases may be leaking. The VISION 8 provides fast responses to a
wide range of gases. It has been designed for maximum uptime, so routine maintenance and service can be
performed quickly and easily. The VISION 8 incorporates a patented EλE Sense Technology®optic system, with
the ability to speciate and identify gases within the same gas family. Combined with our exclusive ChemLogic®
technology, fast and accurate gas detection is achieved utilizing a chemically treated cassette to capture and
record each gas stain.
See Section 6.9 for important disposal information.
WARNING:If the VISION 8 is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
1.2 Sampling and Monitoring
The system draws sample flow simultaneously from all 8-sample locations to the top of the VISION 8. Flow
setup can also be established to draw to the side of the unit (see Section 3.4, Tubing Relocation). Part of the
sample flow is diverted across the ChemLogic cassette where it is analyzed. The 8-sample locations exhaust
through a single port located at the top or side of the VISION 8 (see Section 2.2.5).
1.3 Theory of Operation
The system draws sample flow simultaneously from up to eight points. Part of the sample flow is diverted
across the ChemLogic Cassette. The VISION 8 uses an advanced optical detection system to measure the color
change occurring on ChemLogic cassette. As the target gas is detected, the color from the of the ChemLogic
cassette changes. This color change on the ChemLogic cassette allows the EλE Sense Technology optic
system to qualify and quantify the toxic gas reaction. The VISION 8 will then report an appropriate gas
concentration reading and a speciation of the gas detected.

VISION™ 8 Operating Manual
Chapter 3 – Installation
3.1 Selecting a Location
The VISION™ 8 is designed for safe use under the following conditions:
•Indoor use only
•Altitude up to 2,000 m
•Temperatures 5°C - 40°C
•Maximum relative humidity 80% for temperatures up to 31°C decreasing linearly to 50% relative
humidity at 40 °C
•110/220 VAC supply voltage fluctuations up to +/- 10% of the nominal voltage
•Transient Levels: Impulse withstand (overvoltage) category II of IEC 60364-4-443
The VISION 8 should be placed in a location as central as possible to the locations being monitored while
considering the following restrictions:
•The maximum sample line length is 500 ft. Using the shortest possible sample line length will reduce
transport times and increase the response time of the VISION 8 (see Appendix C)
•A/C power is required to the unit.
•Locate near proper ventilation keeping in mind the maximum length of the exhaust tubing is 25ft.
•The VISION 8 requires stable temperature and humidity levels within range to operate properly.
Do not place the VISION 8 in a location which will expose it to moisture, dust, corrosive gas, or any unusual
environmental conditions which could damage the unit and/or cause it to operate inaccurately.

3.3 Sample Tubing
Sample tubing may be connected to the VISION™ 8 from the top (standard – see Figure 3.3) or left side of the
enclosure. Sample tubing must meet published specifications or be purchased separately from DOD
Technologies (see Parts & Accessories in Appendix A). Fully depress each sample tube into the proper hole
when attaching. To detach the tube, push on the collet and pull the tubing out. For details on exhaust tubing,
see Section 3.6.
Figure 3.3
3.4 Tubing Relocation
The quick connect system used to attach sample tubing and exhaust may be located on the top or left side of
the machine. To move the manifold, follow these procedures:
1. Remove the four (4) mounting screws shown in Figure 3.4.1
2. Remove the four lock nuts holding the cover plate over the manifold opening
3. Remove the cover plate. The section will appear in likeness to Figure 3.4.2
4. Position and align the cover plate over the alternate tubing location
5. Replace the screws holding the cover plate in place and tighten accordingly
6. Place the cover plate over the unused opening and secure with the four replaced lock nuts
IMPORTANT:All sample tubing used with the VISION 8 must be ¼” OD x 3/16” ID FEP Teflon
(500 ft max length). Use of any other tubing may damage the VISION 8 and/or cause
inaccurate gas concentration readings.
IMPORTANT:Sample line tubing should not be disconnected or removed while the unit is
active in analysis mode.

Figure 3.4.1 Figure 3.4.2
3.5 Particulate Filters
Particulate filters must be installed at the end of each sample line to prevent damage to the optic
system. Unused lines must also have a filter installed. Filters require regular maintenance – see Section 6.6.
End-of-line particulate filters must be ordered separately and are available from DOD Technologies (see
Appendix A).
3.6 Exhaust Tubing
The exhaust line must be 3/8” OD x 1/4” ID tubing with a maximum length of 25 feet. Polyethylene is
recommended, although polypropylene or Teflon may also be used. Exhaust tubing is available from DOD
Technologies (see Appendix A).
3.7 A/C Power
Before connecting A/C power to the VISION 8, review the power requirements under System Specifications in
Appendix C.
WARNING: The detachable power cord or the supply line wiring must meet the ratings
specified in Appendix C under System Specifications.
IMPORTANT:All points require filtration to prevent dust accumulation in tubing and internal
damage to the VISION™ 8. Dust that collects in the tubing or the internal system may cause
sample loss and inaccurate concentration readings along with optic issues.

VISION™ 8 Operating Manual
Chapter 4 – Basic Operation
4.1 Introduction
The touch screen on the VISION™ 8 is used for all configuration and control of the unit. Analysis mode is active
by default after power on unless an operator intervenes. The system is designed to continually monitor and
detect target gases. Various tasks can be completed while remaining in Analysis mode, including viewing faults
and events, viewing concentration history & TWA logs, checking point configuration and flow limits.
Analysis is started either by:
1. Power on timeout without user intervention.
2. Touching the Start Analysis after power on.
3. Touching the ‘Start Analysis’ button on the Menu.
Analysis will continue until one of the following occur:
1. Power loss.
2. Entering Setup by touching the Setup button on the Menu and entering an appropriate password which
will halt analysis on all points.
3. A critical machine fault which may stop an individual point or the entire VISION 8.
4.2 Initialization
When powered on, the VISION 8 will begin with an initialization screen, followed by the automatic restart
screen.
NOTE:If another menu button is touched before the timer reaches ‘0’, the system will revert to
that screen and WILL NOT enter Analysis mode (unless the Analysis option was selected). If
the machine loses power at any time, it will return to this screen when power is restored and
automatically re-enter Analysis when the timeout is reached.
