7.3 Process connections
Fitting the transmitter and receiver alignment assemblies
Before you fit the transmitter and receiver alignment assembly to the
process:
Make sure that there are no dangers from the release of potentially
hazardous gases, for example, toxic, flammable, asphyxiant or hot
gases.
Never look into a live process through the eye piece as this may result in
hazardous radiation exposure and permanent eye damage.
Always use adequate eye protection to prevent injury from ejected dust
or dirt and high levels of IR radiation that may be present.
Make sure that the exposed metal parts of the process are at the same
potential as that of its surroundings. If not, use suitable protective
equipment to provide protection against the risk of electric shock.
Make sure that the Laser 3 Plus is switched off.
Note : The mounting / alignment assemblies are adjustable; the receiver alignment /
purging flange may be fixed for shorter path lengths.
Bolt the transmitter and receiver instrument flanges to the process flanges using the
standard bolts, nuts and washers provided.
Note : Use an anti-seize paste on these threads only. Anti-seize paste must not be
used on any other fasteners, nor be allowed to contaminate the optics.
The tolerances of the standard flanges, bolts and holes allow them to be misaligned
from concentric. Therefore, when you fasten the flanges, make sure that the two
flanges are concentric to aid laser beam alignment.
Note: If the process flange temperature is in excess of 135 °C, use a thermal spacer
insulating flange gasket to minimize heat transfer to the instrument flanges.
Ensure flange O-rings are fitted to the analyzer mounting flanges.
Note: Orientate the mounting assembly so that the purge connections are pointing to
the left (as viewed looking at the process wall) to ensure the TU and RU mount
vertically.
