3.3 Connecting the CPV-SC valve terminal
3.3.1 Auxiliary pilot air
Caution
Operate the CPV-SC valve terminal only with the medium
described below:
– If possible, use non-lubricated auxiliary pilot air (connec-
tions 12/14). Otherwise observe the instructions in the
section ”Preparing the compressed air.”
– With CPV-SC valve terminals with internally branched
auxiliary pilot air, the above mentioned remark also
applies to the supply air (connection 1).
The CPV-SC valve terminal is intended for internal or external
pilot air, depending on the end plates fitted.
Terminals for operation with external pilot air are available in
two designs:
– for ducted exhaust air with connections 12/14 and 82/84,
– for non-ducted exhaust air with connection 12/14 and a
large-scale silencer.
Internal pilot air
If the supply pressure of your CPV-SC valve terminal lies be-
tween 3 and 8 bar, you can operate it with internally branched
auxiliary pilot air. In this case the auxiliary pilot air will be
taken from connection 1 in the left-hand end plate.
