Basic safety notes

Intended use

The product was designed to grip and to temporarily and securely hold workpieces and objects.

The product is intended for installation in a machine/system. The requirements of the applicable guidelines must be observed and complied with.

The product may be used only in the context of its defined applica-tion parameters ( 6, Page 13).

SCHUNK assumes that application in question was tested with the calculation program for gripping modules (SSG).

The product is designed for industrial use.

To use this unit as intended, it is also essential to observe the technical data and installation and operation notes in this manual and to comply with the maintenance intervals.

Not intended use

Use which is not specified as an intended use is for instance when the product is for example used as a pressing tool, stamping tool, lifting tool, guide for tools, cutting tool, tensioning mean, boring tool.

Environmental and operating conditions

• Make sure that the product and the top jaws are a sufficient size for the application.

• Observe Maintenance and lubrication intervals ( 9.2, Page 26).

• Make sure that the environment is free from splash water and vapors as well as from abrasion or processing dust. Exceptions are products that are designed especially for contaminated en-vironments.

Product safety

Dangers arise from the product, if:

• the product is not used in accordance with its intended pur-pose.

• the product is not installed or maintained properly.

• the safety and installation notes are not observed.

Avoid any manner of working that may interfere with the function and operational safety of the product.

Wear protective equipment.

NOTE More information are contained in the relevant chapters.

Protective equipment

Provide protective equipment per EC Machinery Directive.

Demands on the top jaws

Arrange the top jaws such that when the product is depressurized it can reach one of the end positions either open or closed and therefore no residual energy can be released when changing the top jaws.

Constructional changes, attachments, or modifications

Additional drill holes, threads, or attachments that are not offered as accessories by SCHUNK may be attached only with permission of SCHUNK.

Personnel qualification

The assembly, initial commissioning, maintenance, and repair of the product may be performed only by trained specialist person-nel. Every person called upon by the operator to work on the product must have read and understood the complete assembly and operating manual, especially the chapter "Basic safety notes" ( 2, Page 7). This applies particularly to personnel only used oc-casionally, such as maintenance personnel.

Inductive proximity switch INW 80/S

Fig. 6 Connection example for IN 80

1 brown 2 black 3 blue

The inductive proximity switches used are equipped with reverse polarity protection and are short-circuit-proof.

Make sure that you handle the proximity switches properly:

• Do not pull on the cable.

• Do not allow the sensor to dangle from the cable.

• Do not overtighten the mounting screw or mounting clip.

• Please adhere to a permitted bend radius of the cable. (☞ catalog)

• Avoid contact of the proximity switches with hard objects and with chemicals, in particular nitric acid, chromic acid and sul-phuric acid.

The inductive proximity switches are electronic components, which can react sensitively to high-frequency interference or elec-tromagnetic fields.

• Check to make sure that the cable is fastened and installed cor-rectly. Provide for sufficient clearance to sources of high-frequency interference and their supply cables.

• Parallel switching of several sensor outputs of the same type (npn, pnp) is permissible, but does not increase the permissible load current.

• Note that the leakage current of the individual sensors (ca. 2 mA) is cumulative.

Troubleshooting

Troubleshooting

Modul does not move?

Possible cause Corrective action

Base jaws jam in housing, possible cause: bolting surface not sufficiently level.

Check the levelness of the bolting surface. ( 7.1, Page 14)

Loosen the mounting screws for the gripper and actuate the gripper again.

Pressure drops below minimum. Check the air supply. ( 7.2, Page 16)

Compressed air lines switched Check compressed air lines.

Proximity switch defective or set incorrect. Repair the proximity switch.

Unused air connections not closed. Close the unused air connections.

Component is broken, e.g. through over-loading

Replace component or send the module with a repair order to SCHUNK. Ensure that the module was only used within its defined application parameters.If necessary, check the application with the calculation program for gripping modules (SSG).

The module does not travel through the entire stroke?


Dirt deposits between the base jaws and the guide

Disassemble and clean module.


Mounting surface is not even enough Check the levelness of the bolting surface. ( 7.1, Page 14)

Module opens or closes abruptly?


Too little grease in the mechanical guiding areas of the module

Clean the module and relubricate it. ( 9, Page 26)

Troubleshooting

08.01|PFH 30-50|en 25

The gripping force drops?


Compressed air can escape Check seals, if necessary disassemble mod-ule and replace seals.

Too much grease in the mechanical motion spaces of the module

Clean the module and relubricate it. ( 9, Page 26)


Module does not achieve the opening and closing times?


Compressed air lines are not installed opti-mally.

If present: Open the flow control couplings on the module to the maximum that the movement of the jaws occurs without bouncing and hitting.

Check compressed air lines.

Inner diameter of the compressed air lines are sufficiently large relative to the com-pressed air consumption

Compressed air lines between module and control valve shoud be kept as short as poss-ible.

Flow rate of valve is sufficiently large rela-tive to the compressed air consumption.

If, despite of optimal air connections, the opening and closing times are not achieved according to the catalog, we recommend the use of quick exhaust valves direct at the module.

3 Locate the springs (43) into the provided undercuts of the bushing (7).

4 Insert the centering bushing (19) and mount the device 1 with screw 1 (3 pieces) onto the housing.

5 Locate the O-ring (26) into the undercut of the piston rod (5) and place the piston (4) carefully with the mounted seals (20) into the device’s bore, until it contacts the pressure springs (43).

6 Put device 2 onto the piston (4) and screw the two devices with screws 2 evenly.

7 Mount the screw (31) and disassemble the two devices.

Repeat this procedure from point 3 to 7 for mounting the oppos-ing piston.

Further assembly is done in reverse order as described under ”Disassembly of the grippers“ ( 9.4, Page 27).
