Raman Rxn2 Operating Instructions
Endress+Hauser 17
5.2 Initial analyzer setup
5.2.1 Installation of Raman Rxn2 analyzer
In some cases, Endress+Hauser requires that installation and initial analyzer setup is performed by trained service
personnel from Endress+Hauser or its affiliated channel partners. This section provides only a basic overview of the
analyzer setup process and does not facilitate a full onsite installation or IQ/OQ. For IQ/OQ, a trained representative
from Endress+Hauser or one of its authorized representatives must be present for both initial inspection and
installation of the Raman Rxn2 analyzer. Before the installation, refer to Site requirements → to prepare the site.
5.2.2 Connecting the touchscreen monitor
Connect a touchscreen monitor to the Display and Touchscreen USB ports on the back of the instrument.

5.2.3 Connecting a probe
5.2.3.1 For single-channel, four-channel, and starter configurations
Raman Rxn2 single-channel, four-channel, starter, and hybrid (ALT channel only) configurations utilize a unique
fiber-optic connector with integrated electrical laser interlock loop. The EO fiber connector on the Raman Rxn2
analyzer is referred to as the ‘device-side’ connector. The EO fiber connector on the probe fiber cable is referred to as
the ‘cable-side’ connector. The instrument device-side connector uses an integrated spring-loaded cap that will
protect the internal fibers from contamination.
1. Remove cover from probe fiber cable-side connector.

2. Clean fiber tips of cable-side connector prior to installation if cleanliness of fiber tips is unknown.
o First use a lens wipe very lightly saturated with a solvent, such as reagent grade acetone or 100 % isopropyl
alcohol (IPA) followed by a final clean with a 1.25 mm fiber cleaning tool. Do not use the same wipe for both
fiber tips.
o Swipe the fiber tip once with the damp portion of the wipe, then swipe once more with a dry portion of the
same wipe. Repeat for both fiber tips.
