GeneralInformation
5. STRUCTURE AND FUNCTION
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 posi-
tions to a higher-level control, the control head has been equipped
with a contactless position measuring 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.
5.1. Manual Control
Standardly, the control head provides the following:
• a magnetic manual control that is easily accessible from the outside
on the basis of encoded magnetic fields for Solenoid Valve 1 (Con-
nection 2/A1), as well as
• a mechanical manual control accessible when the hood is open on
each equipped solenoid valve.
