Optical Oxygen Analyzer
The
OXYvisor
Optical Oxygen Analyzer includes a 316 SS pipe-mount bracket for field mounting. Additional components needed to produce a
functional oxygen measurement include a Barben Oxygen Sensor (BOS) and Pt1000 RTD (Resistance Temperature Sensor).
It is important that the product
Name Plate
(Figure 3) is reviewed to properly identify the product, it’s power input, and the specific hazardous area
markings for the actual unit. It is equally important that the installation control drawing referenced in Table 4, is fully understood and followed along with
the inclusion of any applicable federal, state and local codes.
Section 3 - Installation
3.1 Installation Overview
3.2 Inspection of the Analyzer Shipment (consignment)
Check the packaging and the device for visible damage caused by inappropriate handling, during shipping. Close attention should be paid to the
analyzer enclosure for signs of impact during shipping. All threads should be inspected for burrs and any residual packing material should be removed.
Report any claims for damages immediately to the shipping company. Take pictures and retain damaged parts for clarification. Check the scope of
delivery by comparing the shipping documents with your order for correctness and completeness.
The
OXYvisor
is used to quantitatively measure the amount of oxygen in a gaseous or liquid sample. The analyzer may only be installed as
specified in these instructions per its intended use. Modifications to the analyzer which are not expressly referred to within these instructions will result in
an application which is not in accordance with the intended use. Such modifications are then the exclusive responsibility of the user.
Do not use any damaged or incomplete devices. Danger of explosion in hazardous areas.

3.5 Mounting the Analyzer
Factors to consider when mounting the analyzer:
•
Analyzer/Pipe Mount Orientation
: The analyzer and pipe mount kit can be mated/arranged to mount to either a vertical (Fig. 6) or horizontal pipe
(Fig 7). See Fig. 5 and 6.
!
CAUTION
The front compartment contains the display and electronics boards. It is secured via the 2 mm Hex Lock and is not meant to be opened
in the field at any time. If it is opened, follow the instruction to tighten and secure the Rear (Wiring) Compartment lid. Section 5.4.1.
Section 3
Installation
OPTICAL BUSHING / MAIN ENCLOSURE - The optical bushing going into the upper main enclosure must not be removed nor turned.
There is a locking screw (4 mm Hex) to prevent this.
OPTICAL BUSHING / JUNCTION BOX - To maintain the safety afforded by this analyzer do not change the orientation, remove or re-

WARNING
3.5.1 Orientation of the Junction Box
The Junction Box is not to be adjusted, removed or re-installed in the field for Zone 2 applications. Doing so will affect the safety
evaluation and certificates of the device.
The Junction Box is fitted and located at the bottom of the analyzer with a front-forward orientation as standard and as shown in Figure 5 & 6. The
orientation is locked into position via a Jam Nut and the 3/4” NPT threads (mating to Fiber Optic Bushing) are sealed with a thread-sealant. The
orientation can be specifically selected in the ordering process or sent back to the factory for adjustment.
!
WARNING
1. Locate the proper height for the HMI and display so that it is easily accessible for user
2. Install the L-bracket to the analyzer by tightening down the (4) M6 slotted screws.
3. Install the U-bolt around the pipe at the proper height into the L-bracket and tighten the M8 nuts
4. Double check tightness of the screws and bolts
