6 Functional description
The pneumatically operated product is designed for clamping
workpieces and pallets with extremely high repetition accuracy. 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lockcannotbereleased
until the opening connection is actuated and the PLUS connection is
simultaneously 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.
When the product is not in use, a manually inserted locking bolt or
automatic seal prevents dirt or liquid from penetrating the opening of the
pin.
Safeoperationcanbeveriedbythefollowingstatusesbymeansof
piston position sensing and a positioning check.
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, see section "10.4.3 Tube connection".

INFORMATION
A spring package acts as an energy store and preserves the clamped state in the event of a power failure or
interruption.
►Please contact Zimmer Customer Service if you have any questions.
The product is clamped without pneumatic pressure applied. It is opened when the Open connection is supplied with
compressed air.
6.2 PLUS connection
NOTICE
For dynamic applications, it is recommended to use the product with a pulse at the PLUS connection.
A pulse of compressed air at the PLUS connection supports the clamping process and increases the clamping force. The
product remains spring-loaded.

6.3 Blowing out/cleaning
INFORMATION
This connection is only available in the Advanced series.
NOTICE
The pressure must be able to be switched between the operating pressure for blowing out/cleaning and the
pressure of 1.5 bar for the positioning check.
By actuating the connection, the product is blown out/cleaned via the opening of the pin.
The connection must be switched off before the workpiece and/or pallet is mounted because otherwise a pressure cushion
will build and this could lead to vibrations.
If using with an automatic seal, the Blow out function can only be actuated in the Product closed status.
NOTICE
Recommendation:
►Switch the exhaust air off before the workpiece or pallet is mounted (approx. 1 mm).
►Switch the exhaust air on after the workpiece or pallet has been lifted (approx. 1 mm).
►Comply with permitted operating pressure.
6.4 Positioning check

►Check the control components of the sensing functions regularly.
►If necessary, replace the control components.
►In case of errors in the sensor control, rectify the cause of the errors, see “Error diagnosis” section.
INFORMATION
The operator of the product has sole responsibility for sensing.
►Make sure that the entire contact surface of the product is covered.
►Please contact Zimmer Customer Service if you have any questions.

Two dynamic pressure sensors are integrated for piston position sensing.
Here the position of the piston causes a pressure build-up in the opened status or clamped status. Only one of the two
sensing functions or even both simultaneously for reciprocal control queries can be used.
Controllingthedynamicpressuresensingrequiresareducedpressuresupplylimitedto1.5bar.
The connection designated for this must be controlled for piston position sensing.
Dynamicpressuresensingcanbeperformedwithapressureswitchorowsensor.

VDI2230.
• Strength class of the mounting screws ≥10.9 (DIN EN ISO 4762)
►Comply with the maximum tightening torque.
There are two ways to install the clamping pins:
►Install the clamping pins from above to the
workpiece or pallet with the mounting screw.
• If there is a fault, the workpiece or
pallet can be removed by removing the
mounting screw on the clamping pin.
