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.

2.1 – Features
2.1.1 Warning Labels, Descriptions, & Danger Zones
The below table references all warning labels and their meanings that may be encountered while operating and
servicing the VISION™ 8 continuous gas detection equipment.
WARNING
:
Hot Surface. This surface will be hot to touch and may cause injury. Please
avoid or take caution when working near this zone.
WARNING:
Protective Earth Ground. Terminal Intended for connection to external
conductor for protection against electric shock in case of fault.
ATTENTION:
Please refer to the operations manual for instructions for this system. If
manual is not in country’s native language, requested an updated manual
before use of equipment.
WARNING
:
Electric Shock is possible, please use caution when accessing this zone.
WARNING:
Moving Parts and Hand Crushing possible when accessing the cassette
drawer. Please watch hand placement when working near this zone.

A
This danger zone is in the service access point of
the unit. Users should be aware of hot surfaces
and electrical shock.
B
The danger zone label found on the front of the
unit notifies to taking caution while manually
opening and closing the cassette drawer. Be
aware of hand placement to avoid fingers getting
caught while accessing.

C
These danger zones warn of the potential of
electrical shock by the exterior electrical inputs
and AC voltages inside the instrument.
D
The Protective Earth (PE) label is located inside
the cabinet. It signals the location of the ground
terminal for protection against electric shock in
case of fault.

E
This label, noted on the inner door, advises to
refer to the operations manual for guidance on
proper use of the system. A QR code label is also
adjacent. Scan the QR code for quick access to
the latest version of the operations manual.
2.1.2 Touch Screen Display
The VISION™ 8 uses a full color 15-inch touch panel LCD display. All menus and data entry are accomplished
by touching the appropriate area of the screen – see Chapter 5 “Basic Operation”.
2.1.3 A/C Power & Switch
A/C power is connected, on the left (front-facing) side panel of
the VISION 8, with a standard IEC power cord. The on/off power
switch is located adjacent to the power cable connection.

2.1.4 Flow Connections & Adjustments
Flow connections consist of “quick-connect” ports on the top or side of the VISION™ 8 unit. There are 8-sample
locations, one for each monitored point, and one exhaust outlet.
Flow adjustment valves for all points are located on the front of the device. Sample points 1 through 4 are on
the left side, while sample points 5 through 8 are located on the right. Refer to Section 5.2.3 regarding flow
adjustment.
2.1.5 ChemLogic Cassette
The VISION 8 system utilizes DOD Technologies’ exclusive ChemLogic colorimetric technology. Only use
ChemLogic cassettes specifically offered for the VISION 8 system. Refer to Section 6.5 for additional details
regarding cassette installation and replacement.
2.1.6 Tubing Connections
Sample tubing and exhaust use a quick connection system for easy installation. The sampling and exhaust
connections are made on the top of the VISION 8. See Sections 3.3 & 3.6 for information on connecting the
sample and exhaust tubing. Also see Appendix B for important information on transport times for gas from
sampling point to the VISION 8.
