4 Operating Instructions Horizontal Magnetic Float Switch - HLS

1. General information

The horizontal magnetic float switches described in the operating

instructions are designed and manufactured in accordance with the

current state-of-the-art. During production, all components are subject

to strict quality and environmental criteria. Our management systems

are certified in accordance with ISO 9001.

These operating instructions provide information on how to use the

unit. Compliance with all specified safety instructions and work

instructions are a prerequisite for working safely.

Compliance with the local applicable accident prevention regulations

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.

Technical changes reserved.

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.

3.1 Symbols

DANGER!

... indicates an immediately hazardous situation which

might result in death or severe injuries if it is not

avoided.

WARNING!

... indicates an potentially hazardous situation which

might result in death or severe injuries if it is not

avoided.

CAUTION!

... indicates an potentially hazardous situation which

might result in light or minor injuries or property or

environmental damages if it is not avoided.

INFORMATION

... highlights useful tips and recommendations and

information for efficient and fault-free operation.

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.

3.5 Personnel qualification

WARNING!

Risk of injury due to insufficient qualifications

Improper use can result in significant personal injury and

property damages.

The activities described in these operating

instructions may only be performed by specialist

technicians with the following qualifications.

Specialist personnel

The specialist personnel authorized by the operator is capable of

executing the described work and autonomously detect potential

hazards due their technical training, knowledge of measuring and control

technology and their experience and knowledge of country-specific

regulations, applicable standards and guidelines.

3.6 Personal safety equipment

The personal safety equipment serves to protect the technicians against

hazards that might impact the safety or health while working. When

executing the various tasks on and with the unit, the technicians must

wear personal safety equipment.

Comply with warning signs posted in the work area regarding

personal safety equipment!

The required personal safety equipment must be provided by the
