3 INSTALLATION AND WIRING

Detailed Installation, Wiring, Utility Drawings are included on a Project Basis. Please contact Yokogawa for any project speciﬁ c documentation to ensure correct installation. Drawings provided herein are considered for standard installation use only

3.1 Process Measurement Point Considerations

The following criteria should be considered when selecting the installation point in respect to the process conditions:

• Process Gas Flow Conditions – Laminar, homogenous gas concentration distribution conditions across the measurement point are recommended.

For circular ducts/stacks this condition is generally at least three unimpaired diameters (D) before and after a process bend. For rectangular cross sections, the hydraulic ductdiameter (D) is derived from:

D = (4 x duct cross sectional area) / duct circumference

If neither situation exists or is possible, then distribution of the unimpaired section of duct should be 66% on the inlet side and 34% on the outlet side. Proﬁ ling of the proposed measurement point may be required to ensure that a correct installation point is selected.

• Process Gas Temperature – It is recommended that the analyzer be installed at a location where temperature ﬂ uctuations are minimized. Generally as a guide, if the temperature of the gas at the point where the analyzer is to be installed is to vary by more than +/-10˚C (+/-18˚F) then an “Active” input signal should be used for compensation.

Ensure the analyzer has been selected and conﬁ gured to suit the maximum operating gas temperature.

Lower gas temperatures generally lead to better measurements.

• Process Gas Pressure – It is recommended that the analyzer be installed at a location where pressure ﬂ uctuations are minimized. Generally as a guide, if the pressure of the gas at the point where the analyzer is to be installed is to vary by more than +/- 0.05 Bar (+/- 0.725 psi) then an “Active” input signal should be used for compensation.

Ensure the analyzer has been selected and conﬁ gured to suit the maximum operating gas pressure.

Ensure the process isolation windows have been selected and conﬁ gured to suite the maximum design gas pressure.

Lower gas pressures generally lead to better measurements.

• Process Dust/Particulate Matter – It is recommended that the analyzer be installed at a location where dust loadings are minimized. Dust and other particulate matter will reduce the optical transmission of the measuring laser beam. Within limits, the loss of optical transmission does not effect the measurement however a Warning alarm will be initiated when the transmission falls below allowable limits. The amount of dust loading is also dependant upon the optical path length – Consult Factory for further details.

Lower dust loads generally lead to better measurements.

3.2 Position of Process Flanges for Launch and Detect Units:

Process ﬂ anges should be located on the process such that the Launch and Detect Units can be installed, accessed and removed in a safe and convenient manner.

The following criteria/Check List should be met at a minimum:

• Good, Safe Engineering practices

• Local codes and regulations for such equipment installation

• Appropriate hazardous area (if applicable) precautions

• Owner Company best practice and engineering standards

• Access for personnel to stand in front of launch and Detect Units

• Clearance for installation and removal of Launch and Detect (see below)

• Clearance for installation and removal of purge insertion tubes (if applicable)

• Access to process isolation valves

• Safe routing for interconnecting cables

• Ambient conditions in accordance with analyzer limits

• Access to appropriate utilities

• Adjacent space for mounting to Calibration Cell when off-line

Figure 3 - Launch or Detect Unit Installation Dimensions

The standard ﬂ ange sizes are either 2” or 3” 150# R.F. ANSI as well as DN50 and DN80. Please check the exact ﬂ ange size speciﬁ ed and provided for the particular installation. Other ﬂ ange sizes and a variety of materials (to suit the process) are available so please check these details prior to installing the ﬂ anges on the process.

Note: The process isolation valves should have at least a 1½” (38mm) diameter clear bore size (aperture) to ensure there is sufﬁ cient tolerance to align the laser beam after installation. Ducts and Stacks that have thin and ﬂ exible walls should be reinforced to ensure that the laser beam alignment is maintained at all times. Rigid mounting for the process ﬂ anges is highly recommended to ensure a

lignment is maintained.

In situations where the process ﬂ anges are mounted to these thin and ﬂ exible duct/stack walls, a larger reinforcing plate should be welded around the mounting ﬂ ange area to increase the attaching region. The ﬁ gure below depicts a typical suggestion however; it is the installer’s responsibility to ensure appropriately rigid installation is provided for the analyzer.

The Launch and Detect unit ﬂ anges (and insertion tubes if used) should be installed in such a way that a minimum clear through aperture (opening) diameter of 1 ½” (38 mm) when the distance between the 2” 150# ﬂ ange faces does not exceed 6ft (~2 m).

Note: Larger clear through apertures may be required when operating over longer distances – CONSULT FACTORY for further details.

3.5 Mounting the Launch and Detect Units to the Process Flange

Securely bolt the Launch and Detect Units to the process ﬂ anges using the standard bolt holes provided. Ensure the correct size bolts, nuts, and gasket are used in accordance with the ﬂ ange speciﬁ cations and in accordance with the process speciﬁ cations when applicable.

NOTE: If the process isolation valve ﬂ ange is excessively hot due to the process temperature or radiant heat, then a thermal insolating ﬂ ange gasket should be used in order to minimize the heat transfer to the analyzer ﬂ ange face.

It is generally beneﬁ cial to make the ﬂ ange of the Launch and Detect Units and the ﬂ ange of the process concentric with each other. Due to the large clearance provided by standard ﬂ anges and bolts, it is possible to mount the two ﬂ anges in an un-concentric manner – this should be avoided to aid laser beam alignment.

3.5.1 Process Window Purge Gas Connection

In order to keep the process windows clean (prevent fouling by process gas) it is necessary to purge the windows with a clean dry gas of sufﬁ ciently low dew point.

When measuring Oxygen, Nitrogen should be used for purging the windows. The purge gas or nitrogen should be clean (<0.5 μ particulate), dry (-40˚C dew point), oil free.

The process ﬂ anges are provided with two diagonally opposed inlet ports (typically ¼” OD tube). Use Swagelok (or equal) double ferrule tube ﬁ ttings and connect both ports with ¼” OD stainless steel tubing to the purge gas supply. The exact purge gas ﬂ ow rate will be dependant upon the process conditions that exist at the ﬂ ange connection and therefore, the ﬂ ow rate could be anywhere from 5lts/min to 50lts/min (~10 SCFH to ~100 SCFH).

Ensure the purge gas line is clean and dry prior to connecting to the ﬂ ange to ensure any condensate or debris is not blown on to the windows at initial start-up. The same applies to both Launch Unit and Detect Unit process ﬂ anges, with and without any insertion purge tubes installed.

3.10.2 Launch and Detect Unit Wiring – Standard for CE/ATEX

SPECIAL NOTE: Noise sources magnetically coupled to the 4-pair launch to detect cable can cause errors to the

measurement if the frequency and applied total voltage meet or exceed the following; Frequency range of 0.1 to

7.5 MHz and Total induced voltage of 3Vrms.

A combination of these parameters will cause measurement error outside of the analyzer performance speciﬁ cation. In practice, these potential errors can be easily avoided by routing the 4-pair launch to detect cable away from electromagnetic interference sources that could exhibit these parameters. Such sources might include power transformers, electric motors, electric welding machinery, high voltage power lines, etc. Analyzer grounding wires and any other I/O lines such as 8-pair launch to utility panel cable or A I/O cables to/from the DCS should also be installed with similar basic practices to also ensure there is no additional adverse inﬂ uence on any of the I/O signals.

3.11 Hazardous Area Systems

The TDLS200 Analyzer requires a continuous nitrogen or I/A gas purge to prevent ambient oxygen ingress to the optical path, when oxygen is the measured gas. The ﬂ ow rate can be minimized as long as it prevents any ambient oxygen ingress to the measurement optical path. Other purge gases may be used as long as they do not contain any of the measured gas and are clean, dry, etc. If using a purge gas that also contains the measured gas (e.g. purge with instrument air and measuring process/combustion oxygen) then the Non-Process Parameters software feature/parameters will have to be implemented.

For hazardous area operation, the same nitrogen purge gas is used to purge the entire analyzer (including non-optical path sections such as the electronics).

The process interface may also require purging to maintain clear windows, refer to Process Window Purge details separately.

NOTE: Please also refer to any separate Purge System Original Manufacturers Operating Instructions and Manuals in conjunction with this User Guide.

The Purge Systems are not manufactured by Yokogawa Laser Analysis Division. Please also refer to separate detailed manufacturer’s instructions and start-up information for any Zone 1 or Division 1 automatic purge controller unit operational details. Failure to follow the manufacturer’s guideline can result in damages and/or non-functionality of the purging system!

3.12 Cyclops Division 2/Zone 2 Purge Indictor, with switch

Type Z purging reduces the classiﬁ cation within a protected electronics enclosures from Division 2 or Zone 2 to nonhazardous. Failure to maintain pressure within the protected enclosure shall be detected by an alarm or indicator at the electronics enclosure. The dilution purge time shall be a manual operation and once the electronics enclosure has been purged of ignitable or ﬂ ammable concentrations, only positive pressure of at least

0.20 inches H to remove power from the protected equipment upon the loss of purge pressure. The CYCLOPS Z – Purge Indicator is used to provide safe monitoring of electrical equipment in Division 2 and Zone 2 hazardous areas, which can be used to prevent the possibility of ﬁ re or explosion inside the enclosure of energized electrical equipment, a protective gas supply is used to dilute potentially ﬂ ammable materials to an acceptable level, creating a safe area for the electrical equipment within the enclosure. Positive pressure prevents the ingress of ﬂ ammable materials in the surrounding atmosphere from entering into the enclosure, as long as positive pressure is maintained. After the enclosure is purged, power may be manually applied to the protected electrical equipment.

The CYCLOPS Z – Purge Indicator provides an objective evidence of the presence of adequate positive purge pressure within the electrical equipment enclosure. A normally open differential pressure switch continuously compares the pressure inside the monitored electronics enclosure with respect to the atmospheric pressure surrounding the electronics enclosure. When the monitored electronics enclosure register’s a pressure of at least 0.20 inches H2O (0.50 mbar) above the reference atmospheric pressure a manually controlled dilution time cycle may then begin. Typically, a minimum dilution time cycle is speciﬁ ed to ensure that at least ﬁ ve times the volume of free space in the electronics enclosure is exchanged before power is manually applied to the electrical equipment. (The number of exchanged volumes may be higher in some situations). After the manual dilution time cycle has elapsed and the monitored electronics enclosure pressure is being maintained above 0.20 inches H2O (0.50 mbar), power may be manually applied to the electrical equipment within the purged electronics enclosure. The CYCLOPS Z – Purge Indicator is designed to indicate the presence of purge pressure from one pressure reference point. Several electronics enclosures can be installed in series with purge gas being introduced into the ﬁ rst electronics enclosure and the CYCLOPS Z – Purge Indicator monitoring the last electronics enclosure in the series; multiple electronics enclosures can now be monitored using only one CYCLOPS Z – Purge Indicator. The pressure inside the monitored electronics enclosures must maintain at least

0.20 inches H2O (0.50 mbar) higher than the atmospheric pressure surrounding the electronics enclosure. This ensures that hazardous materials are not going to ingress into the pressurized and now protected electronics enclosures. If any of the electronics enclosures installed in the series door is opened, pressure will show to be below the required 0.20 inches H2O (0.50 mbar) in all electronics enclosures. The exhaust vent which comes as part of the CYCLOPS Z – Purge Indicator casing, can exhaust purge gas from enclosures with volumes up to 15 cubic feet (425 liters).

O (0.50 mbar) is required to be maintained within the electronics enclosure and it is not necessary

WARNING: The number of exchanged volumes may be higher in some situations. Refer to TDLS-200 ATEX Purge Warning Labels for Details.

NOTE: Instrument Air and Nitrogen purge gases have different purge time requirement. It is important to use clean, dry purge gases to ensure the pressure switch contacts do not foul and cause subsequent operating issues (i.e. non-functionality of the Cyclops).

Typically, dilution cycle time is to ensure that at least ﬁ ve (5) times the volume of free space in the enclosure of protective gas supply is exchanged before power is applied to the electrical equipment. Ten (10) times volumes for motors, generators and other rotating electrical machinery.
