17 GWD protection cover for GWA change adapter 8 GWD protection cover for GWA change adapter NOTICE The GWD dust cover is only suitable for covering the GWA change adapter. It must not be used to transport the GWA change adapter together with connected tools. NOTICE If the GWD protection cover is used in very dirty ambient conditions, measures must be taken to ensure that the inside of the changing head mount is not filled excessively with particles of dirt. Regular checks and cleaning, when required, are necessary. NOTICE If there is excessive contamination, there is a risk that the GWK changing head's locking mechanism will not travel fully to its end position and the GWD may be damaged GWA en 17

18 GWD protection cover for GWA change adapter Fig. 6 GWD protection cover The GWD protection cover can be used to prevent contamination of the openings for the pneumatic feed-throughs and of the contacts for the electrical options on the GWA change adapter while it is in the storage rack. The GWD has a built-in clamping mechanism that is activated by locking and unlocking the GWK changing head. This can be used to remove the GWD dust cover from a GWA change adapter and place it on another GWA change adapter. The GWD dust cover (material: PA2200) protects the GWA change adapter from the following contaminants: Dust Chips Various liquids (e.g. cooling lubricant) Designation GWD GWD GWD ID number GWA en

19 Maintenance and Care Maintenance and Care Maintenance intervals NOTICE At ambient temperature above 60 C the lubricants can harden faster. Interval decrease accordingly. Size Interval [Mio. cycles] Lubricants/Lubrication points (basic lubrication) We recommend the lubricants listed. During maintenance, treat all greased areas with lubricant. Thinly apply lubricant with a lint-free cloth. Lubricant point Lubricant Metallic sliding surfaces Molykote BR 2 plus All seals Renolit HLT GWA en 19

20 Maintenance and Care 9.3 Maintenance Servicing and assembling the module Clean all parts thoroughly and check for damage and wear. Treat all greased areas with lubricant. ( 9.2, Page 19) Oil or grease bare external steel parts. Replace all wear parts / seals. Position of the wearing parts ( 11, Page 22) Seal kit ( 12, Page 24) The contact surfaces on the GWK gripper changing head, the pins and the centering taper for the connector parts must always be clean. Make sure that connector parts have noticeable axial and radial play. If this is not the case, remove the connector parts, clean everything thoroughly and screw the connector parts back on. If the GWK gripper changing head is cleaned and maintained, the GWA gripper change adapter should also be cleaned thoroughly. Assembly Assembly takes place in the opposite order to disassembly. Observe the following: Unless otherwise specified, secure all screws and nuts with Loctite no. 243 and tighten with the appropriate tightening torque. Changing the connector part NOTE After the screws (21) are tightened, the connector part should still have noticeable axial and radial play. 1 Remove the screws (21) and replace the connector part GWA en

21 Troubleshooting 10 Troubleshooting Errors The GWA gripper change adapter does not lock properly. Possible cause / Corrective action The contact surfaces of GWK and GWA are dirty. The joint tolerances have been exceeded. Connections for plug connector are bent (joint tolerances). The axial and radial play of the connector part is too small due to contamination. GWK does not lock or unlock GWA en 21
