Under all circumstances attention must be paid to the performance limits, as given in the technical data. Hazards The use of GPS, GPSI and GPSL grippers in an installation is only permissible when they are guarded by MOVING, ISOLATING PROTECTIVE DEVICES as per EN 292-2, para Failure to comply with this protective measure can result in injury due to squeezing, e.g. of fingers. Additional information The aim of the present operating instructions is to enable users to employ GPS, GPSI and GPSL grippers correctly and safely. Should further information be required relating to the particular application, do not hesitate to contact the manufacturer. When ordering operating instructions it is essential to quote the type and serial number. Additional single copies will be provided free of charge.

9 Mounting position and assembly The GPS/GPSI grippers can be mounted in any position. Commissioning With the Montech "QUICK-SET" mounting components structural assemblies can be produced quickly and easily. It should be noted that when mounted horizontally the force due to the weight is F Q. Fig. 8 The force Die due Gewichtskraft to the weight corresponds entspricht to F Q F Q L Types of grippers: GPS-1/GPSI-1/GPSL-1 (L * F Q )max. = 7,5 Ncm GPS-2/GPSI-2/GPSL-2 (L * F Q )max. = 30 Ncm GPS-3/GPSI-3/GPSL-3 (L * F Q )max. = 80 Ncm GPS-4/GPSI-4/GPSL-4 (L * F Q )max. = 160 Ncm 7

12 Commissioning Compressed air supply GPS, GPSI and GPSL are single-acting pneumatic devices. The closing movement is produced by compressed air, opening by spring action.

13 Commissioning Connecting and setting the proximity switches (see Fig.13,14 and 17)) The proximity switches used must have a switching distance (Sn) of 2 mm, be intended for flush mounting and have a casing 6.5 mm in diameter. Each GPS gripper has two holders (50) for proximity switches. Each of these holders has two holes to accommodate the switches. Fig. 13 D 50 A 50 C B As standard, GPS grippers are equipped for scanning the two end positions "Gripper open" (A) and "Gripper closed" (B). On this side the leads of the proximity switches (only GPSL version), can be attached to the air supply hose. If, for space reasons, the positions A and B cannot be used simul-taneously. Position C has to be used instead of A. Simultaneous use of positions A, B and D makes it possible to differentiate between two closed gripper positions, e.g. "gripper closed with product gripped" (B) and "gripper closed without product" (D). When positions C and D are used, stopper (100) must first be removed from the holder (50). (Additional clamping screws (90) and clamping piece can be obtained from the manufacturer see Illustr. 14.) 11

14 Commissioning Gripper open Setting procedure Open the gripper (depressurized) Release the screw 90 (A). Push the proximity switch into opening A as far as the stop. If the switch is electrically connected, the LED should now light up. Secure the proximity switch by tighten the screw 90 (A). Fig. 14 B (B) A (A) Gripper closed The gripper fingers must be designed so they make contact with the product before striking the end-stop of the gripper. Maximum residual stroke from contact with the product to end-stop: 12 GPS-1 = 1.0 mm GPS-2 = 1.6 mm GPS-3 = 2.0 mm GPS-4 = 2.0 mm

15 Commissioning Setting procedure Close the gripper (with compressed air) Release the screw 90 (B). Push the switch into opening B as far as the stop. If the switch is electrically connected, the LED should now light up, both in the position closed without workpiece and closed with workpiece. Secure the proximity switch by tighten the screw 90 (B). Gripper closed without workpiece (scanning position D, Fig.13) Setting procedure Close the gripper without gripping a workpiece. Release the screw 90 (D). Push the electrically connected proximity switch into the hole (D) until the LED lights up. Secure the proximity switch by tighten the screw 90 (D); Fig.14.

Disposal Grippers which cannot be used any more should be recycled, not as complete units, but dismantled to components and disposed of according to the type of material. The kind of material used for each part is shown in the spare parts list. Material which cannot be recycled should be appropriately disposed of. 20
