3 Product description
VEGAWAVE 61 • Two-wire 8/16 mA
32250-EN-221012
It is designed for industrial use in all areas of process technology and
is preferably used for bulk solids.
Typicalapplicationsareoverllanddryrunprotection.Thankstoits
simple and robust measuring system, VEGAWAVE 61 is virtually unaf-
fected by the chemical and physical properties of the bulk solid.
It also works when subjected to strong external vibrations or changing
products.
Solid detection in water
If VEGAWAVE 61 was ordered for solids detection in water, the tuning
fork is set to the density of water. In air or when immersed in water
(density: 1 g/cm³/0.036 lbs/in), VEGAWAVE 61 signals "uncovered".
Only when the vibrating element is also covered with solids (e.g.
sand, sludge, gravel etc.) will the sensor signal "covered".
Function monitoring
The electronics module of VEGAWAVE 61 continuously monitors the
following criteria:
• Correct vibrating frequency
• Linebreaktothepiezodrive
If one of these faults is detected, the electronics signals this via a
denedcurrenttothecontroller.Theconnectioncabletothevibrating
element is also monitored.
Thetuningforkispiezoelectricallyenergisedandvibratesatits
mechanicalresonancefrequencyofapprox.150Hz.Whenthetuning
fork is submerged in the product, the vibration amplitude changes.
This change is detected by the integrated electronics module and
converted into a switching command.
Depending on your requirements, VEGAWAVE 61 with two-wire
electronicscanbeconnectedtodierentcontrollers.Compatible
controllers are listed in chapter " Technical data".
Thedataforpowersupplyarespeciedinchapter"Technical data".
3.3 Adjustment
Ontheelectronicsmoduleyouwillndthefollowingdisplayand
adjustment elements:
• Signal lamp for indication of the switching condition (green/red)
• Potentiometer for adaptation to the product density
• Mode changeover for selection of the output current
3.4 Storage and transport

4.1 General instructions
Note:
For safety reasons, the instrument must only be operated within the
permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Processtting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasionandmechanicalinuences
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
indoors as well as outdoors.
In general, VEGAWAVE 61 can be installed in any position. The instru-
ment only has to be mounted in such a way that the vibrating element
is at the height of the desired switching point.
Use the recommended cables (see chapter " Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cablegland.Rainandcondensationwatercanthusdraino.This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.

Do not hold VEGAWAVE 61 on the vibrating element. Especially with
angeandtubeversions,thesensorcanbedamagedbytheweight
of the instrument.
Remove the protective cover just before mounting.
Theprocessttingmustbesealedifthereisgaugeorlowpressure
in the vessel. Before use, check if the sealing material is resistant
against the measured product and the process temperature.
Themax.permissiblepressureisspeciedinchapter"Technical
data" or on the type label of the sensor.
The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the hexagon above the thread for screwing in.
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
4.2 Mounting instructions
The vibrating element should protrude into the vessel to avoid
buildup.Forthatreason,avoidusingmountingbossesforanges

By default, the potentiometer of VEGAWAVE 61 is set to the right stop
(> 0.02 g/cm³ or 0.0008 lbs/in³). In case of very light-weight solids,
turn the potentiometer to the left stop (> 0.008 g/cm³ or 0.0003 lbs/
in³).VEGAWAVE 61 will thus be more sensitive and can detect light-
weight solids more reliably.
For instruments detecting solids in water, these settings are not ap-
plicable.The density range is preset and must not be changed.
With the mode adjustment (min./max.) you can determine the output
current.
When using a controller, always set the mode switch to max. mode.
In this case, you select the requested mode according to the " Func-
tion table"(max.-max.detectionoroverllprotection,min.-min.

When used on a control system, the following values apply:
• Mode min.
– Vibrating element uncovered - 16 mA ±1 mA
– Vibrating element covered - 8 mA ±1 mA
• Mode max.
– Vibrating element uncovered - 8 mA ±1 mA
– Vibrating element covered - 16 mA ±1 mA
