Clarity - Getting Started Connecting Autosamplers
47
Variant B - started by opening the contacts
In the second scheme there is autosampler
wiring that conversely waits for output
contacts to be opened. This requires different
connection (marked by circle).
The OUTPUT and READY contacts are
connected parallel to each other and the
autosampler will start its operation after both
contacts are opened.
To have the contact on the INT7 board (INT5 or
U-PAD) closed in the initial state, it is
necessary to set the Output Initial item in the
Digital Output Control dialog (accessible from the
Clarity main window) to LOW.

Note: The start output mapping of the Clarity to
individual digital outputs of the A/D converter can
be set in the bottom-right corner of the
System
Configuration
dialog (see Fig. 2 on p. 15). A
detailed description can be found in the Reference
Guide.
6.1.2 AS + LC set – Active Sequence
In LC systems, the autosampler typicaly governs
the timings. The eventual pump gradient or
detector programs are set independently.
