6 Connecting Autosamplers Clarity

Variant A - started by closing the contacts

The first diagram shows the wiring of an autosampler that will initiate the

injection after its input contact is closed.

Fig 19: Wiring of the autosampler - variant A

The injection will start only after both serially connected contacts (Clarity

and the GC) are closed.

After an injection, the autosampler will close the INJECTION contact and

thus the command to start the temperature gradient program will be given.

At the same time, the chromatograph will close the START contact and

thus the command to start the Clarity station acquisition will be given.

If the chromatograph does not have a START OUTPUT contact then the

starting cable IN

must be connected directly to the INJECTION output on

the autosampler (this way, in fact, parallel to the START INPUT contact of

the chromatograph).

To have the contact on the INT9 board ( INT7, U-PAD2 or Colibrick)

opened 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

HIGH.

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 (for more details see the chapter Clarity

Configuration on pg 9). A detailed description of this can be found in the

Reference Guide.
