2.3 Statement of Warranties

The producer guarantees the functional capability of the process engineering and the selected parameters.

2.4 Demounting and Disposal

Unless acceptance and disposal of returned goods are agreed upon, demount the device considering the safety instructions of this manual

and dispose it with respect to the environment.

Before demounting, disconnect the power supply and secure against re-start. Then disconnect the supply lines physically and discharge

remaining energy. Remove operational supplies and other material.

Disposal:

Recycle the decomposed elements: Metal components in scrap metal, Electronic components in electronic scrap, Recycle plastic compo-

nents, dispose the remaining components according to their material consistence.

CAUTION!

Wrong disposal causes environmental damages!

Electronic scrap, electronic components, lubricants and other auxiliary materials are subject to special refuse and can

only be disposed by authorized specialists!

Local authorities and waste management facilities provide information about environmentally sound disposal.

Safety

CAUTION!

Please read the operating manual carefully, before using the device! Observe the installation instructions! Only start

up the device if you have understood the operating manual. The operating company is obliged to take appropriate

safety measure.

The initial operation may only be performed by qualified and trained staff.

Selection and installation of the devices as well as their embedding into the controlling system require qualified

knowledge of the applicable laws and normative requirements on the part of the machine manufacturer.

2.5 General Causes of Risk

This chapter gives an overview of all important safety aspects to guarantee an optimal protection of employees and a safe and trouble-free

operation. Non-observance of the instructions mentioned in this operating manual can result in hazardous situations.

2.6 Personal Protective Equipment

Employees have to wear protective clothing during the installation of the device to minimize danger of health.

Therefore:

Change into protective clothing before performing the works and wear them throughout the process.

Additionally observe the labels regarding protective clothing in the operating area.

Protective clothing:

PROTECTIVE CLOTHING

… is close-fitting working clothing with light tear strength, tight sleeves and without distant parts. It serves preliminari-

ly for protection against being gripped by flexible machine parts.

Do not wear rings, necklaces or other jewellery.

PROTECTIVE GLOVES

…for protecting the hands against abrasion, wear and other injury of the skin.

PROTECTIVE HELMET

…for protection against injuries of the head.

2.7 Conventional Use

The ELGO-device is only conceived for the conventional use described in this manual.

The HMIX2 - ELGO- length measuring system only serves to measure lengths and distances.

CAUTION!

Danger through non-conventional use!

Non-intended use and non-observance of this operating manual can lead to dangerous situations.

Therefore:

Only use the device as described

Strictly follow the instructions of this manual

Avoid in particular:

Remodelling, refitting or changing of the construction or single components with the intention

to alter the functionality or scope of the device.

Claims resulting from damages due to non-conventional use are not possible.

Only the operator is liable for damages caused by non-conventional use.

2.8 Safety Instructions for Transport, Unpacking and Loading

CAUTION!

Transport the package (box, palette etc.) professionally. Do not throw, hit or fold it.

2.9 Handling of Packaging Material

Notes for proper disposal: 2.4

2.10 Inspection of Transport

Check the delivery immediately after the receipt for completeness and transport damage.

In case of externally recognizable transport damages:

Do not accept the delivery or only accept under reserve.

Note the extent of damages on the transportation documents or delivery note.

File complaint immediately.

NOTE!

Claim any damage immediately after recognizing it. The claims for damage must be filed in the lawful reclaim peri-

ods.

2.11 Storage

Store the device only under the following conditions:

Do not store outside

Keep dry and dust-free

Do not expose to aggressive media

Protect from direct sun light

Avoid mechanical shocks

Storage temperature (4) needs to be observed

Relative humidity (4) must not be exceeded

Inspect packages regularly if stored for an extensive period of time (>3 months)

3Product Features

The HMIX2 is an incremental magnetic length measuring system. The sensor technology and translator circuit

are placed in the same small housing. The magnetic tape can also be fixed into a guiding rail by using the pro-

vided adhesive tape. The HMIX2 can be installed up to a maximum distance of 0.8 mm to the magnetic tape.

Overview of the features:

Wear-free, magnetic measuring principle

Direct contactless measurement

High resolution of 1 µm

Repeat accuracy ±1 µm

The distance between sensor and measuring tape can vary between 0.1 and 0.2 mm.

When using without cover tape, a mounting distance up to 0.5 mm is allowed.

With periodic index pulse output or free definable reference pulse (option)

Measuring length theoretical unlimited

Very resistant against dust, dirt and water

3.1 Functional Principle

The basis of the magnetic incremental encoders consists of a scanning technology, which scans the north and

south poles on the coded magnetic tape and produces a single Sine/Cosine wave for each pole.

The complete sine/cosine signal process is interpolated electronically. Depending on refinement of the interpola-

tion, together with the pole distance of the magnetic tape, the resolution of the measuring system is determined.

The magnetic tape (4.6) has a pole pitch of 1 mm. A special evaluation electronic (translator) processes the

sine/cosine wave into square output signals from the signal information of the magnetic tape. These square

signals are equivalent to conventional optical rotary- or linear encoder outputs.

4.1 Identification

The type label serves for the identification of the unit. It is located on the housing of the sensor and gives the

exact type designation (=order reference, 8) with the corresponding part number. Furthermore, the type label

contains a unique, traceable device number. When corresponding with ELGO please always indicate this data.
