Connection 1 is always available on the connection piece (1)
and on the end plate (3).
Connections 3 and 5 are always available on the connection
piece and may also be present on each individual subbase (2)
or end plate (3) depending on how the valve system
is configured (see Fig. 7).

5.5.2 Working connections

The valves direct the air to the pneumatic drives. These are
connected to connections 2 and 4 in the subbases. The working
connections 2 and 4 are always present on each individual
subbase (2).

5.5.3 Pilot air

The pilot supply can be arranged in three different ways
(see section 8.4 "Setting the internal and external pilot air"
on page 93):
Internally via connection 1 if main supply is via connection 1.
Internally via connection 5 if main supply is via connection 5.
Externally via connection X, which is always present
on the end plate.
The pilot control valves are always exhausted via channel R
in the end plate.
Risk of damage to the valve system!
Never close connection R! Closed exhaust outlets will lead
to air congestion and valve damage.
Ensure adequate ventilation through the exhaust air
connection and connection R.
