In the clamping devices, sealing elements are inserted at the bot-
tom, which ensure a hose-free connection to the air supply.
For clamping devices without pneumatic actuation, such as a WDA
99-79 D32 compensation module, sealing elements are likewise
used; these act as sealing plugs.
When changing a change component, it must be ensured that the
sealing elements are not damaged and intact. This is the only way
to ensure that an adapted pneumatic clamping system can be un-
locked and monitored properly.
Air routing in the change components
Function of the workpiece system control
• Max. pressure 2 bar
• Limit volumetric flow to 15 l/min
In order to guarantee reliable evaluation, the pressure and air
volume must be held constant. Pressure fluctuations can affect the
settings of the pressure switch and lead to incorrect measurement
results.
The length and cross-section of the line can affect the switching
time of the control components. It may be necessary to readjust
the control components.
Check the control components of the monitoring functions at
regular intervals. The sealing elements installed in the base of the
change elements must be checked regularly for damage.
If errors occur in the monitoring control system, you must detect
the cause of the error.
