1)
Depending on what you have ordered, the valve terminal will already be equipped with threaded
connectors.
2)
The external pilot air is supplied as standard via port (14).
3)
Requirement: the valve terminal must be fitted with Festo valves (except reversible 2x3/2-way
valves)
4)
Observe the correct position of the seals below the valves, see Chapter 5, Section 5.4.1;
also observe the note in the “common lines” section if you want to remove the pilot exhaust air
through ducts.
5)
If the VTSA... valve terminal is equipped with the end plate type VABE-...R Z -...and with reversible
2x3/2-way valves (ident. code P, Q and R), the operating pressure must also be supplied on
port 12. The valve terminal will then no longer be operated in conformity with ISO standards.
