Notes
Always check that each channel
in multi-channel solutions fulfils
the safety function.
The diagnostic evaluation must
be performed by the software.
The cylinder is stopped via
compressed air. Therefore, the
system contains energy stored
as compressed air. Additional
measures must be taken to be
able to exhaust the cylinder
chambers.
If trapped compressed air can
result in a danger, further
measures are required.
Please note that the technical
values of the components are
complied with during braking
via dynamic energy (e.g. via
resulting pressure peaks).
In the event of a fault of the
5/3-WV, compressed air can flow
through the non-return valve
HGL until the forces are
balanced. That can lead to an
increased overtravel time of the
cylinder.
After the cylinder stops, it can
move depending on the leakage
of the individual components.
This can result in exhausting the
cylinder chambers. Please also
note this for the restart.
