Standard Media Interface (ZU 0576)
Connecting an InTrac 7xx Retractable Fitting
The retractable fittings of the InTrac 7xx series provide pneumatic limit
switches. The media interface shown here converts these pneumatic check-
back signals into electric signals for the Unical 9000(X) probe controller. The
interface is screwed directly to the media connection. Then the corresponding
tubes and hoses are connected to the InTrac 7xx retractable fitting.

The interface is mounted to the retractable fitting using the included hose
clamp. To turn the interface into the required position, you can loosen the fix-
ing screws. The fixing bracket providing strain relief for the media connection
can be fastened with the same or a separate hose clamp – as required.
Use the included connection kit for connecting the tubes and hoses to the
InTrac 7xx retractable fitting. All connections to the Unical 9000 are made by
screwing on the multiplug. To finish the installation, hang the media connec-
tion into the fixing bracket (strain relief) and secure it by tightening the screws.
