VEGASON 54K … 56K 23
Version C and D
The sensors in version C and D are supplied
in three parts (transducer, sensor electronics
and transducer cable). First mount the trans-
ducer (see version B). There is a four-pole
jack at the transducer tube end. A respective
counterpart to the jack is provided in the
connection cylinder of the transducer cable.
Insert the connection cylinder plug into the
jack of the transducer tube.

Then push the connection cylinder onto the
transducer tube (with a slight swivelling mo-
tion) until the mounting mark is no longer
visible.
When the mounting mark is covered by the
cylinder, fasten the cylinder with the two
headless screws. Use a 5 mm hexagon
screwdriver (or Allen wrench).
Now mount the sensor electronics in the
requested location. The sensor electronics is
fastened to a mounting bracket, so that it can
be mounted to a plane surface or to the wall.
Make sure that the sensor housing is
mounted in such a way that there is enough
space above the housing to open the cover.
Now insert the plug at the other end of the
transducer cable into the jack on the elec-
tronics housing.
Note:
Avoid bending the transducer cable too
sharply when laying it out. This is special
cable which could otherwise be damaged.
In addition, make sure that the cable is not
damaged during operation. A signal with a
voltage of approx. 1 kV is transmitted via the
screened wires of the cable . If the cable is
damaged, it could create a danger in Ex
areas.
On the end of the transducer tube you find a
wide and a narrow groove. The wide groove
is used for locking the cylinder with the head-
less screws. The narrow groove is the
mounting mark.
