Surveyor UV/Vis Plus Detector Hardware Manual
• If the autosampler or injector device output relay consists of a single, normally open
terminal and a common ground terminal, connect the normally open terminal to the
RUN terminal on the UV/Vis detector, and connect the common ground terminal to the
GND terminal on the UV/Vis detector. If both of the relay contacts are electrically
isolated from each other and from ground (the device simply closes a contact between the
two relay terminals), then connect either one of the relay terminals to the RUN terminal
on the UV/Vis detector, and connect the other relay terminal to the GND terminal on
the UV/Vis detector.
Note The ground (GND) terminals (pins 1 and 7) on the back of the UV/Vis detector are
tied to a single digital ground. You can use either ground terminal for digital input or
output return connections.
The UV/Vis detector does not use the ZERO connection.
Thermo Scientific data systems do not support this output signal.
The Surveyor UV/Vis ships in two configurations (see
Table 4. Shippable configurations of the Surveyor UV/Vis Plus Detector
Hardware configuration
10 mm standard analytical flow cell
50 mm LightPipe flow cell
When you order the UV/Vis detector with the standard analytical flow cell, the detector
arrives with the flow cell installed. For more information about the standard analytical flow
cell, see
"Standard Analytical Flow Cell"
When you order the detector with the LightPipe flow cell, the LightPipe flow cell comes
packed in a small box within the shipping carton for the detector. In addition to the LightPipe
flow cell (with protective caps on each end), this box contains a plastic bag with the inlet and
outlet tubing and FingerTight fittings. The LightPipe mounting assembly (P/N F3005-010)
is connected to the detector's front panel.
To install the LightPipe flow cell, follow the instructions in
