J22 Analyzer Seals

The optical head of the analyzer interfaces with the process medium through alens and pressure transducer in the cell tube assembly. The lens and pressuretransducer are considered to be the primary seals of the equipment. The ISEM
interface module assembly provides separation between the transmitter head andoptical head, which is considered to be the analyzer’s secondary seal. Although the14

Endress+Hauser

J22 TDLAS Gas Analyzer

Safety Instructions

J22 contains other seals to prevent the migration of process medium into theelectrical wiring system, if either of the primary seals fail only the ISEM interface
module assembly is considered a secondary seal.
The J22 analyzer transmitter housing is certified for Class I, Division 1 with afactory-sealed terminal compartment which eliminates the need for external seals.
The factory seal is only required when used in -40 °C or lower ambient
temperatures.
All optical heads for J22 analyzers systems were assessed as "Dual Seal without
Annunciation" devices. Refer to the markings on the label for the maximum
working pressures.
J22 Gas Analyzers with enclosed sample conditioning system with an optional
heater require a suitable equipment certified seal to be installed within 2”of theouter enclosure wall of the heating circuit.
For Class I Zone 1, installation seals are required within 2" of the analyzer
transmitter housing. If the J22 analyzer includes a heated enclosure, a suitableequipment certified seal shall be installed within 2” of the outer enclosure wall of
the heating circuit as well.
2.8.2

Electrostatic discharge

The coating and the adhesive label is non-conducting and may generate an
ignition capable level of electrostatic discharge under certain extreme conditions.
The user should ensure that the equipment is not installed in a location where it
may be subjected to external conditions, such as high pressure steam, which may
cause a build-up of electrostatic charges on non-conducting surfaces. To clean theequipment, use only a damp cloth.
2.8.3

Chemical compatibility

Never use vinyl acetate or acetone or other organic solvents to clean the analyzer
housing or labels.

Installation

The safety of the analyzer is the responsibility of the installer and theorganization they represent.
 Use appropriate protective safety equipment as recommended by local safety
codes and practices (e.g., hard hat, steel-toe shoes, gloves, etc.) and exercise
caution particularly when installing equipment at a height (i.e., one (1) meter
above ground).

3.1

Lifting/Carrying the Analyzer

The analyzer should be lifted and/or moved by a minimum of two individuals.
Never lift the analyzer by the controller enclosure or conduit runs, cable glands,
cables, tubing or any other part protruding through the enclosure wall or edge ofthe panel or enclosure. Always carry the load using the following points/method
shown under Mounting the Analyzer.

3.2

Mounting the Analyzer

Mounting the J22 is based on the style of analyzer. When ordered without asample conditioning system, the J22 may be specified with an optional mounting
plate for installation. When specified with a sample conditioning system theanalyzer may be wall or post-mounted.
When mounting the analyzer, be sure to position the instrument so that it is notdifficult to operate adjacent devices. Refer to the layout diagrams mounting
dimensions and additional instructions in the Operator’s Manual.

Troubleshooting and Repairs
Cleaning the cell mirror

If contamination makes its way into the cell and accumulates on the internal
optics, a DC spectrum power range exceeded fault will result. If mirror
contamination is suspected, contact Service before attempting to clean the mirrors.
If advised to do so, use the following procedure.
 This procedure should be used ONLY when necessary and is not part of routine
maintenance. To avoid compromising the system warranty, contact Service → before cleaning mirrors.

 Never open the sample cell flanges or the optical assembly unless the poweris turned off.
6. Gently remove the mirror assembly from the cell using a 3 mm hex driver toremove the socket head cap screws and set on a clean, stable and flat surface.

Never touch the coated surfaces of the mirror.
 Always handle the optical assembly by the edge of the mount.
7. Look inside the sample cell at the top window using a flashlight to ensure that

there is no contamination on the top window.

8. Clean the mirror:a.

Put on clean acetone-impenetrable gloves.

b.

Double-fold a clean sheet of lens cleaning cloth and clamp near and along
the fold with the hemostats or fingers to form a “brush.”c.

Place a few drops of isopropyl alcohol onto the mirror and rotate the mirror
to spread the liquid evenly across the mirror surface.

d.

With gentle, uniform pressure, wipe the mirror from one edge to the otherwith the cleaning cloth only once and only in one direction to remove thecontamination. Discard the cloth.
 Never rub an optical surface, especially with dry tissues. Doing this canscratch the coated surface.

e.

Repeat with a clean sheet of lens cleaning cloth to remove the streak left by
the first wipe.

f.

Repeat, if necessary, until there is no visible contamination on the mirror.

9. Replace the O-ring adding a very thin layer of grease. Ensure it is properly

seated.

10. Carefully replace the mirror assembly onto the cell (it is not necessary tomaintain the original orientation).

11. Tighten the socket head cap screws evenly with a torque wrench to 3.5 Nm (30in-lb).

12. Replace the plate on the outside of the SCS enclosure. Disregard this step for

analyzers without an enclosed SCS.

5.2.2

Replacing the membrane separator filter

Make sure that a membrane separator filter is operating normally. If liquid enters
the cell and accumulates on the internal optics, a DC spectrum power range
exceeded fault will result.
To replace the membrane separator filter
1. Close the sample supply valve.
2. Unscrew the cap from the membrane separator.

If the membrane filter is dry:
3. Check if there are any contaminants or discoloring of the white membrane. Ifyes, the filter should be replaced.

4. Remove the O-ring and replace the membrane filter.
5. Replace the O-ring on top of the membrane filter.
6. Place the cap back onto the membrane separator and tighten.

5.2.3

Enclosure purge (optional)

The optional enclosure purge is typically elected when the sample gas contains
high concentrations of H2S. When maintenance of the J22 is required, follow oneof the two methods described below prior to opening the enclosure door.
To purge the enclosure with a gas sensor
 Ensure an appropriate sensor is used based on the toxic components in theprocess gas stream.
1. Allow the sample gas to continue flowing through the system.
2. Open the tee fitting cap on the exhaust port on the lower right side of theenclosure and insert a sensor to determine if there is H2S inside the enclosure.

3. If no hazardous gas is detected, proceed with opening the enclosure door.
4. If hazardous gas is detected, follow the instructions below for purging theenclosure.

To purge the enclosure without a gas sensor
1. Turn off the sample gas to the system.
2. Connect the purge gas to the purge inlet on the upper right side of theenclosure.

3. Open the exhaust on the bottom right side of the enclosure and connect a pieceof tubing that vents to safe area.

4. Input the purge gas at 5 liters per minute.
5. Operate the purge for 22 minutes.

5.2.4

Sample system purge (optional)

1. Shut off gas to the analyzer.
2. Ensure the vent and bypass, if present, are open.
3. Connect the purge gas to ’sample purge in’ port.

4. Switch the gas select valve from ’sample in’ to ’purge in’.
5. Set the flow rate to 1 liter per minute and run the purge for at least 10 minutes

for safety.

5.2.5

Repair verification

When repairs have been completed correctly, alarms will clear from the system.
Residual risk. Some capacitors may remain charged with high voltage in thecase of a single fault.
 Allow 10 minutes before controller covers are opened.
