2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate level switch
has been selected in terms of measuring range, design and specic measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
WARNING!
Observe the working conditions in accordance with Chapter 3 "Specications".
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
The level switch is used to convert a level into an electrical signal indoors and outdoors.
The level switch has been designed and built solely for the intended use described here, and may only
be used accordingly.
The technical specications contained in these operating instructions must be observed. Improper
handling or operation of the level switch outside of its technical specications requires the instrument to
be taken out of service immediately and inspected by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended
use.

2.2 Personnel qualication
WARNING!
Risk of injury if qualication is insucient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be carried out by skilled
personnel who have the qualications described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training, knowledge
of measurement and control technology and on their experience and knowledge of country-specic
regulations, current standards and directives, are capable of carrying out the work described and
independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
2.3 Special hazards
WARNING!
For hazardous media, in addition to all standard regulations, the appropriate existing codes
or regulations must also be followed.
WARNING!
Residual media in dismounted level switches can result in a risk to persons, the
environment and equipment.
Take sucient precautionary measures.
CAUTION!
Operate the level switch only at a minimum distance of 1 m from electromagnetic elds.

4. Design and function
4.1 Description
A oat with an internal magnet, which moves up and down at the guide tube, has an eect on the reed
measuring chain built into the guide tube (reed contacts + resistors). By means of the resistance value
of the measuring chain the ll level can be determined and converted into an electrical signal.
Via the electronics this electrical signal can be linked to various switching functions.
4.2 Scope of delivery
Cross-check the scope of delivery with the delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Handle the level switch with care when removing it from the packaging. The measuring element must
not be exposed to high mechanical loads.
Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site,
sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +80 °C
WARNING!
Before storing the level switch (following operation), remove any residual media. This is of
particular importance if the medium is hazardous to health, e.g. caustic, toxic, carcinogenic,
radioactive, etc..

6. Commissioning, operation
6.1 Operating conditions
The medium to be measured must not be heavily soiled or contain coarse particles.
The level switch is not suitable for crystallising media. If the measuring element comes into contact
with a crystallising medium, the measuring element must be pulled out and cleaned immediately (see
chapter 7.2 "Cleaning").
6.2 Mounting
■
Do not expose the measuring element to high mechanical loads.
■
Do not expose the oat to any impact loads.
■
The sealing faces at the instrument always have to be clean.
■
Only ever screw in, or unscrew, the instrument via the spanner
ats. Never use the case as a working surface.
■
The correct torque depends on the dimensions of the pressure
connection and the gasket used (form/material).
■
When screwing in, do not cross the threads.
■
For information on tapped holes and welding sockets, see Techni-
cal Information IN 00.14 at www.wika.de.
■
The instrument must be earthed via the process connection!

Seal
Correct sealing of the process connections with parallel threads at the sealing
face  must be made using suitable at gaskets, sealing rings or WIKA prole
sealings. The sealing of tapered threads (e.g. NPT threads) is made by providing
the thread with additional sealing material such as, for example, PTFE tape (EN
837-2).

6.3 Keys and functions
The level switch has two operating modes, the display mode and the programming mode. The selected
operating mode determines the respective function of the key.
Jumping into the programming mode
Keep the "MENU" key pressed for approx. 5 seconds. If the password is set to ≠ 0000, a
password will be requested rst-hand. If authentication is successful, then it enters the
programming mode, otherwise it reverts to display mode.
