Note
Note with the CPA−SC valve terminal with HC or
PIconnection and pilot control with internal pilot air:
·
The pilot air is branched centrally from supply channel (1)
on the right of the base block (see Fig.3/5), for all valve
solenoid coils:
·
The right−hand pressure zone must therefore be
operated with a pressure between 3
Ū
8 bar.
