Installing the Optical Bench Assembly
The Optical Bench Assembly – shipped in a separate box – must be in-
stalled in the analyzer’s Upper Enclosure after the analyzer has been
installed.
All electrical connections to the Optical Bench Assembly are made via pre-
wired connector plugs. No hard wiring is required.
To install the Optical Bench (Figure 3-2):
Ensure there is no power being supplied to the analyzer while install-
ing the Optical Bench.
While installing the Optical Bench in the Upper Enclosure, take care
not to damage the enclosure’s joining areas (flamepath).
1. Remove the (24) M10 screws from the Upper Enclosure door and open
it.
2. Locate the Upper/Lower Cam Pins on the Optical Bench Mount and
ensure they are in the “ LOOSE ” position (see removal/installation
instructions on PMT Cover).
The Cam Pins must stay aligned while the Optical Bench is being
installed in the enclosure. The lined groove on the head of each Cam
Pin must be parallel to the Measuring Cell until the Optical Bench is
in place.
While holding the Optical Bench by its upper portion with one hand,
carefully install it in the Upper Enclosure by fitting the Optical Bench
Mount over the Cell Window Housing mount. Rotate the Lower Cam
Pin counter-clockwise and the Upper Cam Pin clockwise until they are
tight (“
CLAMPED ” position).
3. Using the disconnect terminals, connect the green/yellow ground wire
from the interior of the Upper Enclosure to the green/yellow wire con-
nected to the Optical Bench.
