Installation, pneumatic
When using in a vertical or sloping position:
Warning
Uncontrolled moving masses can cause personal injury and material damage (risk of
crushing). If there is a pressure failure, the moveable load (slide mass + mass of the
effective load) will slide down.
Read the documentation for your controller (e.g. CPX-CMAX). There you will find
information on pneumatic circuits with which the moveable mass can be prevented
from falling down.
Check whether safety measures are required to prevent slow sinking as a result of
leakage (e.g. toothed latches or moveable bolts).
Connect the tubing connections in the supply ports. The
threaded connectors are marked with different colours on the
releasing ring:
–
blue releasing ring at connection
