and general safety regulations for the area of use of the unit is
required.
The operating instructions are a component of the product and must
be kept in the immediate vicinity of the unit where they are accessible
to the technicians at all times. Pass on the operating instructions to
subsequent users or owners of the unit.
The technicians must read and understand the operating instructions
prior to starting any work.
The general terms and conditions from the sales documents apply.

2. Design and function
2.1 Functional description
Horizontal magnetic float switches work on the floating principle with
magnetic transmission. The float is attached to a supported, swivelling
lever and moves with the level of the medium being measured. When a
preset switch point is reached, a reed contact (inert gas contact) within
the contact pipe is actuated by the magnet inside the lever. By using a
permanent magnet and a reed contact the switching operation is non-
contact, free from wear and needs no power supply. The functioning of
the horizontal float switch is independent of foaming, conductivity,
vapours, bubble formation and vibrations. The signal processing is
universal. Direct connection to PLCs, NAMUR connections, signal
amplifiers or contact protection relays is possible.

3.2 Proper intended use
The HLS horizontal magnetic float switches are solely intended for
monitoring the liquid level of fluids. The area of use is based on the
technical performance limits and materials.
The fluids must not be contaminated nor contain coarse particles
nor tend to crystallize. It must be ensured that the magnetic float
switch materials that come into contact with the media are
sufficiently resistant to the monitored medium. Not suitable for
dispersion, abrasive fluids, highly viscous media and paints.
Compliance with the usage conditions specified in the operating
instructions is required.

Operating Instructions Horizontal Magnetic Float Switch - HLS 7
Do not operate the unit in direct proximity of ferro-magnetic
environments (distance min. 50mm).
Do not operate the unit in direct proximity of strong
electromagnetic fields or in direct proximity of facilities that can
be impacted by magnetic fields (distance min. 1m).
The magnetic float switches may not be subjected to strong
mechanical stresses (impact, bending, vibrations). The unit is
exclusively designed and constructed for the intended use
described here and may only be used accordingly.
The switching points of the magnetic float switch cannot be
adjusted.
These instructions are intended for technicians who execute the
installation and calibration.
Compliance with the relevant safety regulations for the use is
required.
Compliance with the technical specifications in these operating
instructions is required. Improper use or operation of the unit
outside the technical specifications requires immediate shut-
down and inspection by an authorized WIKA service technician.
Claims of any kind due to improper use are excluded.
DANGER!
When working on containers, there is a risk of poisoning
or suffocation. Work may only be performed using
suitable personal safety equipment (e.g. respiratory
protection, protective clothing, etc.).

3.3 Improper use
Any use that exceeds the technical performance thresholds or that is
incompatible with the materials is considered improper use.
WARNING!
Injury due to improper use
Improper use of the unit can result in hazardous
situations and injuries.
Do not modify the unit without authorization
Do not use the unit in potentially explosive areas.
Any use beyond the proper intended use or any other use is considered
improper use.
Do not use this unit in safety or emergency off equipment.
3.4 Responsibility of the operator
The unit is used in the industrial sector. The operator is therefore subject
to statutory obligations with respect to occupational safety.
Compliance with the safety instructions in these operating instructions
and the applicable safety, accident prevention and environmental
protection regulations for the area of use of the unit is required.
In order to safely work on the unit, the operator must ensure
the operating personnel is regularly trained in all matters
pertaining to occupational safety, first aid and environmental
conservation and is familiar with the operating instructions and, in
particular, the safety instructions contained therein
the unit is suitable for the application in accordance with the
proper intended use (check for improper use).
After check, improper use is excluded.
