In addition, there are pneumatic connections on the back of the positio-
ner for integrated installation in single--acting linear actuators.
- Actuating pressure Y1
- Exhaust air output E (not in explosion proof version)
In the ex--factory state, these connections are sealed by screws (see
figure 3-1, page 33, figure 3-3, page 34 and figure 3-4, page 35).
