5.2.2 Functional tests
Functional test when used as a holding device (clamping function)
The frequency (or testing interval) of functional tests is to be determined dependent on the application / risk
evaluation. At least once or month or every 100,000 switching cycles unless C-type standards or other regu­
lations require more.
Instructions for performing the structural test (è 6.4 Clamping force test).
5.2.3 Creating a tubing connection to the clamping unit
In case of use in normal ambient atmosphere (without particles):
• Remove covers (if present) from the compressed air supply
ports.
• Remove dirt particles and foreign matter from the ports and
tubing lines.
• Use the shortest suitable tubing lines. This will reduce switching
times.
• Create tubing connections between the supply ports of the
clamping unit 2 and those of the cylinder 1.

To prevent dirt particles from entering the pneumatic system when
used in ambient air with fine particulate matter or fine mist:
• Use a barbed fitting (e.g. QS-CM-M5) instead of the filter nipple
in the exhaust channel 7 of the spring interior.
• Run hose into an area with clean ambient atmosphere.
