3 Proper use
NOTE:
The GPH8000 series gripper should only be used in its original state with its original accessories, without any
unauthorizedchangesandwithinthescopeofitsdenedparametersforuse.
ZIMMER GmbH shall accept no liability for any damage caused by improper use.
The gripper is designed for operation with compressed air only. It is not suited for operation with other media such as
liquids or gases.
Thegripperisusedasdenedunder"Properuse"inenclosedroomsfortemporarilygripping,handlingandholding
workpieces.
It is not suitable for clamping workpieces during a machining process or for direct contact with perishable goods.
Proper use of the gripper also includes the forces and torques that may be acting in addition to the
gripping force (see product data sheets at www.zimmer-group.de).
4 Personnelqualication
Installation,commissioningandmaintenancemayonlybeperformedbyqualiedpersonnel.Theymusthavereadand
understood the installation and operating instructions in full.
5 Function
The gripper has a double-sided ventilated pneumatic piston. Alternate ventilation causes the jaw to move sideways. The
energy supply can be made one-way or two-way.
The GPH8000 series gripper is available in three versions:
• Synchronous without clamp
• Synchronous with one clamp
• Asynchronous with two clamps
One or more clamping elements are used to secure the positioning of the gripper jaws.

6 Installation
NOTE:
Non-compliance may result in damage to the system
Switchothepneumaticenergysupplybeforeanyassembly,installationormaintenancework.
CAUTION:
Non-compliance may result in damage to the system
• Risk of injury in case of unexpected movement of the gripper when pneumatic energy is connected.
• Switchothepneumaticenergybeforeallwork.
• Secure the pneumatic circuit against being switched on unintentionally.
• Checkthepneumaticcircuitforanyexistingresidualenergy;bleedifnecessary.
WARNING:
• Risk of injury in case of unexpected movement of the machine or system into which the gripper is to be
installed.
• Switchothepowersupplytothemachinebeforeallwork.
• Secure the machine against being switched on unintentionally.
• Check the machine for any residual energy.
The opening pressure for the gripper and the installed clamp amounts to at least 4 bar!
6.1 Installing the gripper
The gripper may only be mounted on a surface intended for this purpose. The mounting surface must correspond
tothenecessaryatness.
Depending on the design size, cylinder screws from M3 to M16 and of strength class 8.8 are used.
The following tightening torques must be observed during installation:
The following work steps are to be carried out to install the gripper:
► Insertcenteringsleevesorcylindricalpins(optional)intotheappropriatetsonthegripper.
►Position the gripper on the intended mounting surface using the centering sleeves.
►Fasten the gripper using cylinder screws.
• When doing so, use threadlocker to secure the cylinder screws.
• Threadlocker: Use a threadlocker suitable for the application area.
►Mount the pneumatic connection.
• Closeounusedpneumaticconnectionswithdummyplugs.
6.2 Checking operational readiness
After the gripper has been properly installed, use the following characteristics to check whether it is ready to be
operated:
►Look and listen for leaks in the pneumatic connections.
►Check all mounting screws for their prescribed tightening torque.
►Look and listen for leaks in the pressurized gripper.
►Check to make sure the gripping process is functioning properly by opening and closing the gripper manually.

6.3 Using the stroke adjustment screw
Synchronous:
► Settherstside.
►Move to the limit stop.
►Set the second side.
• Secure the stroke adjustment screw using a threadlocker suitable for such use.
Asynchronous:
►Each stroke can be set independent from one another.
• Secure the stroke adjustment screw using a threadlocker suitable for such use.
6.3.1 Installation of stroke limitation at the factory
The adjustment screws and end stops 3for the stroke setting are installed at the factory.
Thus, the two end positions can be reduced by up to 40 mm.
6.3.1 Adapter piece installation for stroke limitation
If you require a larger reduction of the stroke limitation, the stroke can be further reduced by the use of
additional spacers.
An example depiction of an adapter piece 9can be viewed in the following image.
Inner installation of the adapter piece 9for the inner end position.
• Secure the stroke adjustment screw and spacer with a screw locking device suitable for the application.
