Please contact Zimmer Customer Service if you have any questions.
5.3 Functional description
The pneumatically operated product is designed for clamping workpieces and workpiece-clamping devices with extremely high
repeatability. Due to its structural design, the system is clamped without pneumatic pressure applied.
The clamping force can be signicantly increased by using an additional impulse on the PLUS connection. The form-t arrest
cannot be released until the release connection is actuated, the clamp dog is pressurized and the PLUS connection is simulta-
neously vented.
The product is optimally adapted to the clamping contour of the clamping pin. The resulting surface contact creates an
extremely rigid system that can absorb high forces and torques.
The basic version features two rotation prevention devices.
The blow-out or cleaning function prevents dirt or liquid from collecting in the pin holder and contact surface. When clamped,
the seal on the contact surface prevents dirt or liquids from penetrating into the product.
Safe operation can be veried by the following statuses by means of piston position sensing and a positioning check:
• Product opened
• Product closed (clamping pin clamped)
• Product closed (no clamping pin present)
• Workpiece present (rests upon the contact surface)
All functions can be controlled directly by means of the contact surface and the standard connections with O-rings. There is also
the option to control the product by means of alternative connections on the bottom of the product.

and the fastening screws7.
The following work steps must be observed during installation:
ÖIf the PLUS connection2 is not in use, insert a lter cm into the
connection (lter included loose).
ÖThe lter cm must be ush with the bottom of the product during
installation.
►Insert the O-rings cp.
ÖLubricate the O-rings.
►Insert the product into the intended position on the mounting
piece.
ÖMake sure that the standard connections for the tubeless
connection are positioned correctly.
►Manually screw the fastening screws7into the thread until the
product is in contact.
ÖInsert the straight pin for the rotation prevention6if this is
required!
►Tighten the fastening screws 7with the corresponding tightening
torque.
ÖThe vent holes and lters have to be atmospherically vented over

8.3 Checking operational readiness
After the product has been properly installed, the following properties must be checked to verify that it is ready to be operated:
• Check pneumatic connections for leaks by looking and listening
• Check all fastening screws for their prescribed tightening torque
• Check the product for leaks while it is pressurized by looking and listening
8.4 Disassembly
Removal is carried out in the reverse order of that described in Section „Montage Mechanik“.
9. Operation
During machining, the entire contact surface of the zero-point clamping system must be covered so that no dirt can penetrate.
►Before any clamping, thoroughly clean the contact surfaces between the zero-point clamping system, the clamping pin and
the material to be clamped.
►Protect the pin hole from dirt when the product is not in use.
►To do this, use accessories such as the sealing pin or automatic seal.
►During operation, secure the zero-point clamping system against unintentional loosening.
9.1 Positioning check
The product enables the testing or monitoring of the support using an
externally connected ow meter or dynamic pressure indicator.
This inspection veries that the workpiece or clamping plate is
correctly supported on the product.
The ow or dynamic pressure is measured by means of the
designated borehole boin the housing.

INFORMATION
The operator of the product has sole responsibility for the positioning check. Sensing for the positioning check
is performed by means of an external ow meter or dynamic pressure indicator. The entire contact surface of the
product must be covered to ensure correct sensing during the positioning check.
Operating pressure for the positioning check: 1.5 bar
To use this function, an adjustable pressure switch must be connected upstream. This reduces the operating
pressure to the required 1.5 bar.
ÖThe power supply line is for blowing out, cleaning and the positioning check.
Please contact Zimmer Customer Service if you have any questions.
9.2 Piston position sensor
INFORMATION
The operator of the product has sole responsibility for piston position sensing. Sensing is performed by means of an
external ow meter or dynamic pressure indicator.
The entire contact surface of the product must be covered to ensure correct sensing during the piston position
sensing.
Operating pressure for piston position sensing: 1.5 bar
Please contact Zimmer Customer Service if you have any questions.

10. Maintenance
The maintenance interval depends on the respective application. The higher the strain, the more frequently maintenance must
be carried out.
NOTICE
In case of visible damage or signs of malfunction, the zero-point clamping system must be taken out of operation
immediately. Do not start the product again until the damage has been repaired.
►Replace any worn components.
Interval Maintenance work
After 10,000 cycles or every 3 weeks Visual inspection
The visual inspection merely involves visually inspecting component parts and their
function. If any irregularities or damage are identied during the visual inspection, a
more detailed check of the component parts must be carried out.
►Carry out a visual inspection.
►Clean the product if it is dirty.
After 50,000 cycles or every year Measure the clamping force
►Measure the clamping force.
• Suitable devices for measuring the clamping force are available as
accessories.
ÖClamping force undershot by less than 15%
• Further use at the customer's discretion.
• Or have Zimmer GmbH perform the check.
ÖClamping force undershot by more than 15%
• Have Zimmer GmbH perform the check.
Dismantling and reassembling the product without authorization may result in complications, as special installation equipment is
required in some cases. Zimmer GmbH accepts no liability for any resulting malfunctions or damage.
