Function
Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) gen-
erates the closing force on the diaphragm pressure piece. The force
is transferred via a spindle which is connected to the actuator piston.
5.2.1 Control functions (CF)
WARNING!
For control function I: Danger if pilot pressure fails.
For control function I (CFI) control and resetting occur pneumati-
cally. If the pressure fails, no defined position is reached.
▶ To ensure a controlled restart, first pressurize the device with
pilot pressure, then switch on the medium.
