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 or an "Ex" symbol (when applying Directive 2014/34/EU), those only for preventing material damage with a "STOP" sign. WARNING! Imminent explosion! The notes indicated by this symbol are given to prevent explosion damage. -

Coupling versions FADB FADS Fig. 1: Coupling types Data relating specifically to the coupling The orderspecific data relating to a delivery are, if known in case of an order, listed on the title orderreleated page. -
Page 8: General Notes
General notes 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. All persons involved in the installation, operation, maintenance and repair of the coupling must have read and understood these operating instructions and must comply with them at all times. -
Page 9: Safety Instructions
Safety instructions Any changes on the part of the user are not permitted. This applies equally to safety features designed to prevent accidental contact. Obligations of the user • The operator must ensure that all persons involved in installation, operation, maintenance and repair have read and understood these operating instructions and comply with them at all times in order to: ─... -

Page 12: Marking The Coupling Parts For Explosion Protection
In the standard design the fusing temperature of the fusible safety screw is 140 °C, and the material used for the seals is Perbunan (for a maximum continuous operating temperature of 85 °C). As an extended standard (for continuous operating temperatures of up to 110 °C and/or synthetic oil ), the coupling can be fitted with seals made of Viton. -
Page 13: Conditions Of Use For Fludex Couplings In Potentially Explosive Areas
Conditions of use for FLUDEX couplings in potentially explosive areas The coupling with fusible safety plug with indication is suited for the service conditions specified in Directive 2014/34/EU: • Equipment group II (use above ground) temperature class T3 of category 2 and 3 for areas where there are explosible gas, vapour, mist, air mixtures as well as for areas where dust can form explosible atmospheres. - Page 14 When machining the finished bore the parts must be carefully aligned. For the permissible radial and axial runout errors and the permissible cylindricity tolerances, see DIN ISO 286. The parts must be fitted on the marked faces ( In case of part 2/3, part 4 and part 9 great caution is necessary owing to the rotating cams.

Page 16: Set Screws
6.1.4 Set screws Hexagon socket set screws with cup points to DIN 916 must be used for set screws. The following guidelines must be observed! The length of the set screw must be selected so that it fills the threaded hole, but does not project from the hub (L x 1.2). -
Page 17: Balancing
6.1.5 Balancing FLUDEX couplings are delivered balanced. Prebored NEUPEX addon couplings are delivered unbalanced. It is recommended that these parts are balanced to suit the application after finishboring (see DIN ISO 1940 and DIN 740/2), minimum balancing quality G16. Balancing is normally done by drilling material away. If onelevel balancing is required on brake disk / brake drum (13;... -
Page 18: General Information On Fitting
General information on fitting During fitting, the "Safety Instructions" in section 3 must be observed. Fitting work must be done with great care by trained and qualified personnel. As early as during the planning phase it must be ensured that sufficient space is available for installation and subsequent care and maintenance work. -
Page 19: Alignment
If necessary, heating the brake disk and the NEUPEX coupling hubs (to maximum + 150 °C) will facilitate fitting. With temperatures over + 80 °C the flexible elements (12) must be removed from the coupling part 1 before heating. Before fitting coupling part 2 the part 3 must be fitted on the shaft. Take precautions to avoid burns from hot parts. -
Page 20: Possible Misalignments
Possible misalignments ΔKa Axial misalignment Angular misalignment Radial misalignment Fig. 10: Possible misalignments Misalignments of the coupling parts in relation to each other can be caused by inaccurate alignment during assembly, but also by actual operation of the equipment (expansion due to heat, shaft deflection, insufficiently rigid machine frames, etc.). -

Page 28: Changing The Shaft-Sealing Rings
10.2 Changing the shaft-sealing rings shaft-sealing rings are wearing parts subjected to relatively low stresses in the coupling. On couplings which are filled with oil no maintenance interval need be adhered to. On couplings which are filled with water the shaft-sealing rings of the inner seal must be replaced after 12 000 operating hours or after 2 years of operation. -
