If the supply pressure of your CP terminal is in the
range 3 to 8 bar, you must operate the terminal with
external pilot air. In this case the external pilot air is
supplied via port 12/14 on the CP terminal.

pilot air
PLEASE NOTE
•
Use regulated external pilot air (3 to 8 bar).
This will ensure reliable faultless operation of the
CP terminal.
•
Ensure that the regulated external pilot air is
supplied or taken at only one point by means of
common tubing for all valve plates on the
CP terminal. This also applies when the CP
terminal is operated with different pressure zones
(see diagram).
