2. Design and function
2. Design and function
2.1 Functional description
Float switches work on the oat principle with magnetic transmission.
A reed contact integrated in the guide tube is actuated through the
magnetic eld of a permanent magnet, when a preset switch point
is reached. The permanent magnet is located within a oat , which
changes its height with the level of the medium it is monitoring. The
switching status of the reed contact can be evaluated and processed by
a connected control device.
The number and arrangement of oats is dependent on the number of
the dened switch points, their contact function and also the distance
between the switch points.

4.1 Transport
Check the oat switch for any damage that may have been caused by
transport. Obvious damage must be reported immediately.
CAUTION!
With improper transport, a high level of damage to property
can occur.
▶
Observe the symbols on the packaging.
▶
Handle packed goods with care.
4.2 Packaging and storage
Do not remove packaging until just before commissioning.
Permissible conditions at the place of storage:
Storage temperature: -30 … +80 °C (-22 … +176 °F)
5. Commissioning, operation
■
Observe all instructions given on the shipment packaging for
removing the transportation safety devices.
■
Remove the oat switch carefully from the packaging!
■
When unpacking, check all components for any external damage.
5.1 Mounting preparation
Functional check

described in chapter 5.3 and the switch points can be
operated manually.
WARNING!
Ensure that the functional check does not start any
unintended processes.

5. Commissioning, operation
Ensure that the sealing faces of the vessel or oat switch are clean and
do not show any mechanical damage.
5.2 Mounting
EN
■
Observe the torque values of screws specied in pipetting work.
■
In the selection of the mounting material (sealings, screws, washers
and nuts), take the process conditions into account. The suitability
of the sealing must be specied with regard to the medium and
its vapours. In addition, ensure it has corresponding corrosion
resistance.
■
Mount the oat switch either via mounting thread or mounting
ange (not illustrated).
■
The guide tube should not be inclined more than a maximum of
30° to the vertical.
■
If the geometry of the oat does not t through the process
connection, the oat must be removed before mounting.
- For this, before removal, mark
the position of the oat stops
with a waterproof pen
- Mark the mounting position of
the oats (e.g. “Up”)
- After the oat switch has been
mounted, the oat should be
re-attached within the inside of
the tank (pay attention to the
mounting position!).
- Float stops must then be
re-attached at the marked
points.
■
The number of oats and also
the position of the oat stops are
dependent upon the dimension
and the number of switch points.

5.3 Electrical connection
■
The electrical connection must only be made by qualied skilled
personnel.
■
Connection details and switching functions are given on the
connection diagram. Connection terminals are appropriately marked.
■
Seal the cable bushing at the connection housing (see
illustration in chapter 5.2 “Mounting”).
■
The mains connection lines to be provided must be dimensioned
for maximum instrument current supply and comply with IEC 227 or
IEC 245.
WARNING!
Electrical connection errors of the oat switches can destroy
the reed contacts. This can lead to a malfunction in the plant
and thus lead to injury to personnel or damage to equipment.
▶
No direct operation in circuits with inductive loads.
▶
No direct operation in circuits with capacitive loads, e.g.
PLC, PCS or cable lengths > 50 m.
▶
Do not exceed the permissible switching power.
DANGER!
Physical injuries
With oat switches with connection cable without protective
conductor connection, it is possible for the switch to become
live in the event of a malfunction. Any contact can result in
physical or even fatal injury.
▶
Only operate these switches at safety extra-low voltage
in accordance with VDE0100 or fit them so that the float
switch is electrically connected to the equipotential
bonding.

Repairs must only be carried out by the manufacturer.
Perfect functioning of the oat switches can only be
guaranteed when original accessories and spare parts are
used.
7.2 Cleaning
CAUTION!
Physical injuries and damage to property and the
environment
Improper cleaning may lead to physical injuries, damage
to property and the environment and to damage to the
instrument. Residual media in the dismounted instrument can
result in a risk to persons, the environment and equipment.
▶
Rinse or clean the removed instrument.
▶
Sufficient precautionary measures must be taken.
▶
Do not use any aggressive cleaning agents.
▶
Do not use any pointed and hard objects for cleaning.
1. Prior to cleaning, properly disconnect the instrument from the process

2. Aufbau und Funktion
2.1 Funktionsbeschreibung
Schwimmer-Magnetschalter arbeiten nach dem Schwimmerprinzip
mit magnetischer Übertragung. Ein im Gleitrohr eingebauter ReedKontakt wird durch das Magnetfeld eines Permanentmagneten bei
Erreichen eines vorgegebenen Schaltpunktes betätigt. Der Permanent-
magnet bendet sich in einem Schwimmer , der seine Höhenlage mit
dem Flüssigkeitspegel des zu überwachenden Messstoes verändert.
Der Schaltzustand des Reed-Kontaktes kann durch eine nachgeschaltete Steuereinrichtung ausgewertet und weiterverarbeitet werden.
Die Anzahl und Anordnung der Schwimmer ist abhängig von der Anzahl
der vorgegebenen Schaltpunkte, deren Kontaktfunktion sowie dem
Abstand der Schaltpunkte.

Die Flüssigkeiten dürfen keine starken Verschmutzungen oder
Grobteile aufweisen und nicht zum Auskristallisieren neigen. Es
ist sicherzustellen, dass die messstoberührten Werkstoe des
Schwimmer-Magnetschalters gegen den zu überwachenden
Messsto ausreichend beständig sind. Nicht geeignet für Dispersionen, abrasive Flüssigkeiten, hochviskose Medien und Farben.
