STRUCTURE AND FUNCTION 6.
The Control Head Type 8681 has been designed for use
as actuation of pneumatically operated process valves and/
or for recording the switching states of these.
For the recording and feedback of the process valve
switching positions to a higher-level control, the control
head has been equipped with a contactless position mea-
suring system, which works with three discrete, adjustable
feedback signals (Teach-In Function).
Various pneumatic and electrical connection variants are
available.
Positions and status information can be indicated by means
of three signal colors.
Manual Control 6.1.
Standardly, the control head provides the following:
a magnetic manual control that is easily accessible from •
the outside on the basis of encoded magnetic fi elds for
Solenoid Valve 1 (Connection 2/A1), as well as
a mechanical manual control accessible when the hood •
is open on each equipped solenoid valve.
