Information:
This information applies only to special versions!
VEGAPULS 68 is also available in versions where the antenna has a
bigger diameter than the process fitting (thread, flange). The antenna
must therefore be disconnected from the process fitting before
mounting. Proceed as follows:
1 Loosen the hexagon screws (3) on the antenna socket with an
Allen wrench (size 3)
2 Remove the antenna (4)
Note:
The plastic conemust not be pulled out of the antenna socket.
3 Insert the antenna from below into the vessel socket and secure it
against falling off
4 Retighten the antenna with hexagon screws to the antenna socket;
torque max. 10 Nm (7.5 lbf ft)
