3-10 | IPS-4 Dual Bench (UV / IR) Analyzer
Installing the Optical Bench-UV Assembly
After the analyzer has been installed, the Optical Bench Assembly can
be mounted in the Electronics Enclosure. All electrical connections to the
Optical Bench Assembly are made via pre-wired connector plugs (no hard
wiring is required).
Ensure there is no power being supplied to the analyzer while install-
ing the Optical Bench Assembly.
Refer to Figure 3-3a for the locations of the Optical Bench Assembly,
boards, cable connectors, and other components discussed in this
procedure.
To install the Optical Bench Assembly:
1. Using the locator pins on the UV/VIS Optical Bench Assembly, posi-
tion the Bench Assembly to the upper Window Housing Assembly
(Figure 3-3a). Mount the clamp on the interface and secure the assem-
bly in place.
2. Connect the Heater/OT (over-temperature) Switch wiring harness
connector from the Optical Bench to J401B on the Relay board.
3. Connect the RTD cable connector from the Optical Bench to the in-
line connector (labelled “CON2”) that leads to J402 on the Analog
board.
4. Connect the DC cable connector from the Xenon Flash Lamp
Assembly to J2 on the Xenon Lamp board, located near the top of the
Electronics Enclosure.
5. Connect the ribbon cable (Cable 5) from the Optical Bench to connec-
tor P4 on the Detector Interface board, mounted to the MCU board.
6. If the lamp assembly is provided with a purge fitting, connect the
tube from the air inlet on the bottom of the enclosure to the fitting on
the lamp.
Clamp the ribbon cable using the clamp provided, leaving enough
length on each end to avoid pulling or binding.
Do not attempt to adjust the Optical Bench. The Optical Bench has
been factory aligned to the mounted Measuring Cell. See additional
information on the dual Optical Bench application in the Overview
section of this manual.
