Supply, waste air and service line connection to pneumatic module
Prerequisite: You have installed the ET 200X (see Section 3.1).
1. Use tubing exhibiting outside tolerance from FESTO for example, type PUN ...
or type PAN .... Push the tubing having an outer diameter complying with
Table 3-2 as far as the stop over the appropriate connection on the module
(refer to Figure 3-7).
2. Close unused service connections with plugs. (2 plugs are included with the
pneumatic module.)
Note
Bundle laid tubing with hose band clips for the sake of tidiness on your system.
Directing waste air into the environment
If you want to direct the waste air from the module into the environment, you can
leave the waste air connection on the module open (refer to Figure 3-7). We
recommend you to place a silencer on the waste air connection to reduce noise.
You will find the order number for the silencer in Appendix A.
Containing waste air
If you place tubing on the waste air connection of the module, you can then guide
the waste air away or collect it. Collection is practical, for instance, the pneumatic
system is enriched with oil and you would like to dissipate the oily air.
In the case of contained air, the tubing has to be run by the shortest possible route
to a large-volume waste air line or outdoors. Please note that the operating
pressure must not rise with hose length. Waste air must not be impeded at the
waste air connection of the module.
Note
When the waste air from several modules is funneled, the resulting back pressure
in the common waste air line my be too high – for example, with a long waste air
tube length or a small tube diameter. In this case we recommend you to install a
non-return valve between the waste air line of the pneumatic module and the
common waste air line – for example, type H-QS-8 from FESTO.
