Generalinstructions
5 STRUCTURE AND FUNCTION
The control head Type 8681 has been designed for use as an actuator
for 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
contact-free position measuring system which operates with 3 discrete,
adjustable feedback signals (Teach-In function).
Various pneumatic and electrical connection variants are available.
Positions and status information can be indicated by 3 signal colours.
Further colours are available for the büS/CANopen design.
5.1 Manual override
The control head provides the following as standard:
• A magnetic manual override that is easily accessible from the
outside on the basis of encoded magnetic fields for solenoid valve 1
(connection 2/A1), as well as
• a mechanical manual override accessible when the hood is open
on each equipped solenoid valve.
