5 Transport and storage
Protect the product against external force during transport (impact, stroke,
vibrations, etc.).
Transport and/or store the product in unopened, undamaged original packaging.
Protect the product from dust, dirt, moisture as well as heat and ultraviolet
radiation.
Ensure that the product has not been damaged by either mechanical or thermal
influences.
Check the product for transport damage before assembly.
6 Function
Float switch 2282 is designed to enable economical monitoring of liquids in tanks. It is
available in two different plastic versions, both of which have two different attachments for
several application options. Further advantages are its maintenance-free design, compact
size, and the high switching capacity of the reed contacts.
The float switch is installed horizontally in the tank.
The plastic float switch has a welded-in magnet and moves up and down on a hinge
to monitor the level of liquid in the tank.
In the end position, the welded-in magnet actuates the embedded, potential-free
reed contact.
The mounting position determines whether the normally open/normally closed
switching function is applied. This can be altered by turning the product 180°.

9 Installation
Checking the installation conditions
No free-floating solids or ferritic parts are present in the liquid, as these can cause
the float switch to malfunction.
If the liquid contains sediment or particulate matter, appropriate precautions must
be taken to keep these away from the float switch.
Are the maximum working pressure and maximum temperature values being
observed?
Checking the mounting position
The float switch must be able to move freely along the entire path length.
It should not touch either the walls, bottom, or lid of the tank.
Ensure that there is no turbulence from inlet valves or agitators.
If possible, install the product in an easily accessible position. This makes
subsequent maintenance and replacement work easier.
The product should be installed horizontally.
Check whether the product has been installed in the normally open or normally
closed position.
Mounting position
Installing the float switch mechanically
The float switch cable must not be connected.
Make sure that the thread in the tank is free of contamination.
Carefully insert the float switch into the opening and turn it several revolutions by
hand.
With a maximum torque of 4 Nm, tighten the float switch until the flattened side
edges are as vertical as possible.
Check whether the correct mounting position (NO/NC) has been achieved.
Check whether the connection is tight.
In the event of a leak, remove the sensor again completely and remount it using
additional sealing materials (e.g., PTFE tape).
Page 2
The float switch is insulated, therefore a separate grounding wire
is not required.
Ensure that the voltage values for the float switch
correspond to those for the system.
Make sure that the supply cable is de-energized.
Connect the connection cable for the float switch to the
supply cable.
Connect external devices.
- The float switch is operational once the supply voltage has
been switched on.
You can check that the switching output is working correctly
by manually raising and lowering the float.
