6.5 Piston position sensor
INFORMATION
This connection is only available in the
Advanced
series.
NOTICE
Malfunctions in case of non-compliance
►
Make sure that products can be loaded or unloaded without damage if pneumatic piston position sensing is
not being used.
Air flows out of the boreholes when piston position sensing is being used. An unobstructed air discharge must be
ensured so that piston position sensing can function.
Pressure fluctuations can influence the settings of the pressure switch or flow sensors and lead to incorrect
measurement results.
►
Keep the pressure and the air volume constant for dynamic pressure sensing.
Line lengths and line cross-sections can influence the switching time of control components.
►
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 piston position 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 flow sensor.
