Safety loads Check the table for maximum permitted loads. Excessive forces or torques can damage the gripper, cause functioning troubles and endanger the safety of the operator. F s, Mx s, My s, Mz s, are maximum permitted static loads. Static means still jaws. F d, Mx d, My d, Mz d, are maximum permitted dynamic loads. Dynamic means running jaws. m, is the maximum permitted weight of each gripping tool, when the gripper works without speed adjustment. If the weight is over the permitted value, it is necessary to decrease the speed of the jaw by using flow controllers (not supplied).

Gripper fastening The gripper can be fastened to a static or moving part. When on a moving part, you must pay attention to the forces created by inertia on the gripper and its load. It can be fastened from the top or from the bottom. Use 4 screws (SC) and 2 centering sleeves (BC). 4 centering rings for the gripping tools and 2 centering sleeves for the housing are supplied in the packaging.

Cautions Never let the unit come into contact with corrosive substances, soldering splashes or abrasive powders as they may damage the gripper. Never let personnel or objects stand within the operating range of the gripper. Never operate the gripper if the machine on which it is fitted does not comply with safety laws and standards of your country. Maintenance Grease the gripper after 1 million cycles with: BERULUB FG-H 2 EP (Lubricant NSF H1 Registration No. 14486). The picture below shows the jaw maximum backlash. 3/215 35
Compressed air feeding The compressed air feeding can be accomplished on the lateral air ports (P and R) with fittings and hoses (not supplied). Or it can be accomplished directly by the bottom air ports (G and H) removing the plugs (E and F) and providing other plugs (not supplied) for the lateral air ports (P and R). Compressed air in P - H: gripper opening. Compressed air in R - G: gripper closing. The compressed air, must be filtered from 5 to 4 µm. Maintain the medium selected at the start, lubricated or not, for the complete service life of the gripper. The pneumatic circuit must be pressurized progressively, to avoid uncontrolled movements. O-Ring Ø1x4 (GUAR-91) P R R E G F H P O-Ring groove Ø6H11x.7 +.1 Pneumatic circuit Possible problems on a compressed air circuit: 1- Pressure variation. 2- Pressurizing with empty cylinders. 3- Sudden pressure black-out. 4- Excessive speed of the jaws. Possible solutions: 1- Compressed air storage (A). 2- Start-up valve (B). 3- Safety valve (C). 4- Flow controller (D). 36 3/215
