3.2 Principle of operation
Area of application
31763-EN-060830
OPTISWITCH 4000 C - with transistor output 5
OPTISWITCH 4000 C is a level sensor with tuning fork for level
detection.
It is designed for industrial use in all areas of process
technology and can be used in liquids.
Typical applications are overfill and dry run protection. With a
tuning fork of only 40 mm length, OPTISWITCH 4000 C can be
also mounted, e.g. in pipelines from DN 25. The small tuning
Page 6
Product description
fork allows use in vessels, tanks and pipes. Thanks to its
simple and robust measuring system, OPTISWITCH 4000 C is
virtually unaffected by the chemical and physical properties of
the liquid.
It functions even under difficult conditions such as turbulence,
air bubbles, foam generation, buildup, strong external vibration
or changing products.
Fault monitoring
The electronics module of OPTISWITCH 4000 C continuously
monitors via frequency evaluation the following criteria:
l Strong corrosion or damage on the tuning fork
l loss of vibration
l Line break to the piezo drive
If a malfunction is detected or in case of power failure, the
electronics takes on a defined switching condition, i.e. the
output transistor blocks (safe condition).
Physical principle
Power supply
Packaging
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx. 1200 Hz. The
piezos are fixed mechanically and are hence not subject to
temperature shock limitations. The frequency changes when
the tuning fork is covered by the medium. This change is
detected by the integrated oscillator and converted into a
switching command.
OPTISWITCH 4000 C is a compact instrument, i.e. it can be
operated without external evaluation system. The integrated
electronics evaluates the level signal and outputs a switching
signal. With this switching signal, a connected device can be
directly activated (e.g. a warning system, a PLC, a pump etc.).
The exact range of the power supply is stated in the "Technical
data" in the "Supplement".
3.3 Operation
The switching status of OPTISWITCH 4000 C can be checked
with closed housing (signal lamp). Products with a density
>0.7 g/cm³ (>0.025 lbs/in³) can be detected.
3.4 Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test according to DIN 55439.

4.1 General instructions
Switching point
In general, OPTISWITCH 4000 C can be mounted in any
position. The instrument must be mounted in such a way that
the tuning fork is at the height of the requested switching point.
The tuning fork has lateral marking (notches), marking the
switching point with vertical mounting. The switching point
refers to water (1 g/cm³ or 0.036 lbs/in³). When mounting
OPTISWITCH 4000 C, make sure that this marking is at the
height of the requested switching point. Keep in mind that the
switching point of the instrument is shifted if the medium has a
density other than water.

Moisture
Use the recommended cables (see chapter "Connecting to
power supply") and tighten the cable gland.
You can give your OPTISWITCH 4000 C additional protection
against moisture penetration by leading the connection cable
downward in front of the cable entry. Rain and condensation
water can thus drain off. This applies mainly to mounting
outdoors, in areas where moisture is expected (e.g. by
cleaning processes) or on cooled or heated vessels.

Mounting
Pressure/Vacuum
Handling
Welded socket
The process fitting must be sealed if there is gauge or low
pressure in the vessel. Before use, check if the seal material is
resistant against the measured product and the process
temperature.
The max. permissible pressure is stated in the "Technical
data" in the "Supplement" 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 in the instrument!
Applying tightening force on the housing can damage its
internal mechanical parts.
To screw in, use the hexagon above the thread.
4.2 Mounting instructions
For welded socket with O-ring in front and welding marking.
OPTISWITCH 4000 C has a defined thread runout point. This
means that every OPTISWITCH 4000 C is in the same position
after being screwed in. Remove therefore the supplied flat seal
from the thread of OPTISWITCH 4000 C. This flat seal is not
required when using a welded socket with front-flush O-ring.
Before welding, unscrew OPTISWITCH 4000 C and remove
the rubber ring from the welded socket.
The welded socket has a marking (notch). For horizontal
mounting, weld the socket with the notch facing upward or
downward; in pipelines aligned with the direction of flow.

Adhesive products
In case of horizontal mounting in adhesive and viscous
products, the surfaces of the tuning fork should be vertical in
order to reduce buildup on the tuning fork. The position of the
tuning fork is marked by a marking on the hexagon of
OPTISWITCH 4000 C. 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.
In adhesive and viscous products, the surfaces of the tuning
fork should protrude into the vessel to avoid buildup. Therefore
sockets for flanges and mountings bosses should not exceed
a certain length.

Flows
If OPTISWITCH 4000 C is mounted in the filling stream,
unwanted switching signals may be generated. Mount OPTI-
SWITCH 4000 C at a location in the vessel where no disturbing
influence from e.g. filling openings, agitators etc. can occur.
To minimise flow resistance caused by the tuning fork,
OPTISWITCH 4000 C should be mounted in such a way that
the surfaces of the blades are parallel to the product
movement.
