Operation Principle

The FLOWVENT Control Top works with a microprocessor that contains the
software for operation, visualization and intelligent position detection. The valve
stroke is detected by a contactless position measuring system integrated in the
control top and the information is supplied to the microprocessor.
Pneumatic and electronic modules are located inside the control top. The
pneumatic modules in this case are solenoid valves, the number of which varies
between 0 and 3, depending on the intended purpose. Control air is supplied to
the relevant control air chambers via air connections at the outside of the control
top.
The main control air is supplied to the actuator via a separate air connection on
the control top through a hose. The exhaust air of the main actuator is discharged
via an air connection with sound absorber or optionally via an adjustable exhaust
air throttle. The exhaust air from the optional lifting actuators is discharged via
separate air connections with sound absorber.
If the FLOWVENT Control Top is used only as a position indicator without a pilot
valve, the control air supply must be connected directly to the air connection of
the main actuator.
Due to the illuminated dome integrated in the cap of the control top the light
emitting diode arranged on the evaluation electronics can be seen even if the
hood is closed. The light-emitting diode allows visualization of the main functions
of the valve, see Section 6.5, Page 45

3.2.2

Control top without solenoid valves

The FLOWVENT Control Top, without pilot valves, functions as a position
indicator During and after SETUP it indicates the status of the process valve
locally by a coloured LED under the illuminated dome so that it is visible over a
long distance.
The position feedback signals are supplied to the user in one of the following
ways, depending on the communication method selected:

•

24V DC PNP switching output

•

AS interface data bit
