Legal notes Warning note concept

This manual comprises notes which must be observed for your personal safety and for preventing material damage. Notes for your personal safety are marked with a warning triangle, those only for preventing material damage appear without a warning triangle. Depending on the level of hazard, the warning notes are shown in reverse order of seriousness, as follows.

DANGER

means, that death or serious injury will result, if the appropriate preventive action is not taken.

WARNING

means that death or serious injury may result, if the appropriate preventive action is not taken.

CAUTION

means that a slight injury may result, if the appropriate preventive action is not taken.

NOTICE

means that material damage may result, if the appropriate preventive action is not taken.

Where there is more than one hazard level, the warning note for whichever hazard is the most serious is always used. If in a warning note a warning triangle is used to warn of possible personal injury, a warning of material damage may be added to the same warning note.

1. Technical data

Enclosed with the coupling delivery and the documentation is an orderspecific dimensioned drawing showing all the technical data necessary for fitting (see Fitting data field in figure 1). The coupling can be fitted with the aid of these instructions only in conjunction with the orderspecific drawing of the coupling.

The technical data to the ARPEX couplings listed in these instructions are documented on the orderspecific drawing of the coupling (see "Operating and Coupling Data" fields in figure 1) and in the current product catalogue and are available on request or can be accessed at any time on the Internet (see cover at back).

Because of customerspecific adaptations the standard design is frequently deviated from. The technical data on the orderspecific drawing of the couplings should always be followed before the data in the current product catalogue, therefore.

These data together with the contractual agreements on the coupling determine the limits of its proper use.

WARNING

Risk of serious injury through flying fragments

Risk of serious injury through flying fragments and/or risk of damage to the coupling. The coupling must be designed with an application factor appropriate to the application. In the event of a change in operating conditions (output, speed, prime mover and driven machine) the design must always be checked.

ARPEX 8706 en Operating instructions 10/2017

2. General notes

2.1 Introduction

These instructions are an integral part of the delivery of the coupling and must be kept in its vicinity for reference at all times.

WARNING

Risk of serious injury through flying fragments

Risk of serious injury through flying fragments and/or risk of damage to the coupling.

– All persons carrying out work on the coupling must have read and understood these instructions and

must adhere to them.

– Any changes on the part of the user are not permitted. This applies equally to safety features designed

to prevent accidental contact.

– The coupling is designed only for the application specified in the order. Other operating conditions are

regarded as incorrect.

The "FLENDER coupling" described in these instructions has been developed for stationary use in general engineering applications. The coupling serves to transmit power (torque and speed) between two shafts or flanges connected by this coupling.

The coupling has been manufactured in accordance with the state of the art and is delivered in a condition for safe and reliable use.

The coupling complies with the requirements in Directive 2014/34/EU.

The coupling must be used and operated strictly in accordance with the conditions laid down in the contract governing performance and supply.

The coupling described in these instructions reflects the state of technical development at the time these instructions went to print.

In the interest of technical progress we reserve the right to make changes to the individual assemblies and accessories which we regard as necessary to preserve their essential characteristics and improve their efficiency and safety.

2.2 Copyright

The copyright to these operating instructions is held by Flender.

These instructions must not be wholly or partly reproduced for competitive purposes, used in any unauthorised way or made available to third parties without our agreement.

3. Safety instructions

Observe the information in section 2, "General notes".

DANGER

Danger of explosion

Risk of explosion when operating in potentially explosive areas. Incorrect changes made to the coupling will create ignition sources. Any changes on the part of the user are not permitted. This applies equally to safety features designed to prevent accidental contact. For the use in potentially explosive environments the protective equipment must comply at least with type of protection IP2X.

DANGER

Danger of explosion

Risk of explosion when using unsuitable components in potentially explosive areas. Use the coupling only for the approved zones and equipment groups. In case of doubt, contact Flender.

DANGER

Danger of explosion

Risk of explosion when operating in potentially explosive areas. Damaged coupling modules and coupling parts are potential explosion hazards. Use only undamaged coupling components. Operating the coupling with damaged coupling parts is not permitted in potentially explosive environments in accordance with Directive 2014/34/EU.

3.1 Obligations of the user

• The operator must ensure that everyone carrying out work on the coupling has read and understood these instructions and is adhering to them in every point in order to:

─ avoid injury or damage,

─ ensure the safety and reliability of the coupling,

─ avoid disruptions and environmental damage through incorrect use.

• During transport, assembly, fitting, demounting, and maintenance of the unit, the relevant safety and environmental regulations must be complied with.

• The coupling may only be maintained and/or repaired by persons qualified for the work concerned (see "Qualified personnel" on page 3 of this manual).

11

ARPEX 8706 en Operating instructions 10/2017

DANGER

Danger to life through switchedon installation

Risk of being caught or drawn in by rotating and/or movable parts. To carry out work on the coupling, the system must always be stopped. The drive unit must be secured against being switched on accidentally (e.g. by locking the key switch or removing the fuses from the power supply). A notice should be attached to the ON switch stating clearly that work is in progress. At the same time the complete installation must be without load, so that no danger occurs during demounting operations.

WARNING

Risk of serious injury through rotating components

Risk of serious injury through contact with rotating components. The coupling must be fitted with suitable safeguards to prevent any contact. The operation of the coupling must not be impaired by the safeguard. This also applies to test runs and when checking the direction of rotation.

WARNING

Risk of serious injury through flying fragments

Risk of serious injury through flying fragments and/or risk of damage to the coupling. If any malfunctions or changes are noticed during operation, the drive assembly must be switched off at once.

Note

If the coupling is fitted in plant or equipment, the manufacturer of such plant or equipment must ensure that the contents of the present instructions are incorporated in his own instructions.

WARNING

Risk of serious injury through flying fragments

Risk of serious injury through flying fragments and/or risk of damage to the coupling through use of defective spare parts. Flender guarantees only the genuine spare parts supplied by Flender. Nongenuine spare parts have not been tested or approved by Flender. Nongenuine spare parts may alter technical characteristics of the coupling, thereby posing an active or passive risk to safety.

ARPEXturbo couplings are allsteel couplings and can be supplied, inter alia, in the types shown in figures 3 and 4. The plate packs are arranged in the fitted coupling modules between the flanges of the coupling parts and bolted to them alternately. The ARPEX coupling is torsionresistant and transmits the torque without circumferential backlash. In axial and radial direction the coupling is however still flexible and can absorb axial, radial and angular misalignment of the coupled units.

6. Fitting

6.1 General information on fitting

Observe the instructions in section 3, "Safety instructions"!

Fitting work must be done with great care by trained and qualified personnel (see "Qualified personnel" on page 3 of this manual).

As early as during the planning phase it must be ensured that sufficient space is available for installation and subsequent care and maintenance work.

Adequate lifting equipment must be available before beginning the fitting work.

DANGER

Danger of explosion

Risk of explosion when operating in potentially explosive areas. The conductivity and coating thickness of the paint applied may give rise to electrostatic charges and are potential ignition sources. If coated couplings are used in potentially explosive areas, the requirements made of the conductivity of the coating and the limitation on the thickness of the coat applied must be observed in accordance with standard "DIN EN 134631". Where coatings have a thickness < 200 μm, no electrostatic charge is to be expected. Where coatings are thicker than 200 μm, an electrostatic charge, e.g. by cleaning the coupling, must be avoided.

DANGER

Danger of explosion

Risk of explosion when operating in potentially explosive areas through damage. Damaged coupling modules and coupling parts are potential explosion hazards. Use only undamaged coupling components. Operating the coupling with damaged coupling parts is not permitted in potentially explosive environments in accordance with Directive 2014/34/EU.

DANGER

Danger of explosion
