Product flow
To make sure the tuning fork of VEGAWAVE S
61 generates as little resistance as possible
to product flow, mount the sensor so that the
surfaces are parallel to the product movement.
Adhesive products
In case of horizontal mounting in adhesive pro-
ducts, the surfaces of the tuning fork should be
vertical in order to reduce buildup on the tuning
fork. On the screwed version you will find a mar-
king on the hexagon. With this, you can check
the position of the tuning fork when screwing
it in. When the hexagon touches the seal, the
thread can still be turned by approx. half a turn.
This is sufficient to reach the recommended
installation position.

Preparing the connection

Note safety instructions
Always keep in mind the following safety
instructions:
•
Connect only in the complete absence of
line voltage
•
Take note of safety instructions for Ex
applications
Connect the voltage supply according to the
following connection diagrams. The electronics
module with relay output is designed in protec-
tion class I. To maintain this protection class, it is
absolutely necessary that the ground conductor

be connected to the internal ground terminal.
The data for power supply are specified in chap-
ter "Technical data".
Connection cable
VEGAWAVE S 61 is connected with standard
cable with round cross section. An outer cable
diameter of 5 ... 9 mm (0.2 ... 0.35 in) ensures
the seal effect of the cable gland.
Make sure that the cable used has the required
temperature resistance and fire safety for max.
occurring ambient temperature
If cable with a different diameter or wire cross
section is used, exchange the seal or use an
appropriate cable connection.

Connection procedure

Proceed as follows:
1. Unscrew the housing lid
2. Loosen compression nut of the cable gland
and remove blind plug
3. Remove approx. 10 cm (4 in) of the cable
mantle, strip approx. 1 cm (0.4 in) of insula-
tion from the ends of the individual wires
4. Insert the cable into the sensor through the
cable entry
5. Lift the opening levers of the terminals with
a screwdriver (see following illustration)
6. Insert the wire ends into the open terminals
according to the wiring plan
7. Press down the opening levers of the
terminals, you will hear the terminal spring
closing
8. Check the hold of the wires in the terminals
by lightly pulling on them
9. Tighten the compression nut of the cable
entry gland. The seal ring must completely
encircle the cable
10. If necessary, carry out a fresh adjustment
11. Screw the housing lid back on
The electrical connection is finished.
