8�2 Connection
Î
Apply pilot pressure to the connector. The clamping jaws
will close together and the connection to the test piece is
possible ( Figure 2 ).
Î
Grip the test piece and plug it up to the stop straight onto
the connector ( Figure 3 ).
Doing so will prevent any damage to the front seal caused
by any sharp edges on the test piece and ensure a correct
connection.
Attention: Insert the test piece carefully and not with force
onto the connector.
Î Vent the pilot pressure line. The test piece tightens itself to
the connector and creates a pressure-tight connection.
Attention: Make sure that the clamping jaws on the test
piece grip correctly, that the connector is seated prop-
erly (the test piece must not wobble) and that the pres-
sure-tight connection has been made. Only then is the
connector connected correctly. Otherwise the test piece
may spring out of place and medium may escape.
Î Pull lightly on the test piece (red arrow Figure 4 )
in the direction opposite that of the connection to make
sure that the connector is firmly in place.
- The connector is now connected pressure-tight to the test
piece.
Î To start the testing procedure, apply pressure to media
inlet ‘B1’.
