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 preliminarily 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 product described in this manual was developed to execute safety-related functions as a part of an entire assembly or machine. It is the

responsibility of the manufacturer of a machine or installation to ensure the proper functioning of the system. The ELGO-device is only

conceived for the conventional use described in this manual. The FMAX - ELGO- length measuring system only serves to measure lengths.

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 (4.4) needs to be observed

Relative humidity (4.4) must not be exceeded

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

3Product Features

Series FMAX is an absolute magnetic length measuring system and only of use for recordation of lengths. It con-

sists of a guide carriage, where sensor technology and translator are placed, and a guide rail FSMAB. A mag-

netic tape is installed on the guide rail. The guide carriage is guided contactless over the magnetic tape.

Typical applications are paper cutting machines, hydraulic presses, wood- and sheet metal processing ma-

chines.

Overview of features:

no reference adjustment necessary

direct measurement

measuring lengths up to 650 mm

high resolution up to 0.01 mm

repeating accuracy +/- 0.01 mm

protection against dirt and dust

easy installation

Interfaces: RS232, RS422 and SSI (9.1)

3.1 Functional Principle

Three sensors are guided over a magnetic tape, recorded with three tracks. The following illustration shows the

three magnetic tracks with following north- and South Pole magnetization, sensed by magneto-resistive resistor

measuring bridges. Between the single magnetic tracks there always is an equal shifting X. This is evaluated

together with the single signs of the resistive resistor measuring bridges and delivers an absolute value. An un-

ambiguous classification of a absolute position is possible by the combination of the phasing of the three mag-

netic tracks. The phase position zero repeats every 650 mm for each of the three tracks.

4.1 Identification

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

exact type designation (=order reference, 9.1). Furthermore, the type label contains a unique, traceable

device number, the production date as well as the hardware and software versions. When corresponding with

ELGO always indicate this data.
