Operation Principle
The control top T.VIS A-15 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.
Electrostatically endangered components/modules!
•
The control top contains electronic components that are sensitive to
electrostatic discharge (ESD). Contact with electrostatically-charged persons
or objects can endanger these components. In the worst case they are
destroyed immediately or fail after being put into operation.
•
Observe the requirements of DIN EN 61340-5-1 and 5-2 to minimize or
prevent the possibility of damage resulting from sudden electrostatic
discharge.
•
Also take care not to touch electronic components when supply voltage is
present.
•
Use ESD-compliant packaging when returning electronic components.
(Contact GEA Tuchenhagen if you have any questions.)
3.1.2
Control top without solenoid valves
The T.VIS A-15 control top without solenoid valves acts as a position indicator.
After programming, it indicates the status of the process valve locally by coloured
LEDs 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 switching output
•
AS interface data bit
•
DeviceNet data bit
•
IO-Link data bit
For programming, the process valve must be moved once to its end positions by
an external solenoid valve.
3.1.3
Control Top with Solenoid Valves
The control top with solenoid valves acts as a control top. The signalling takes
place in the same way as with the control top without solenoid valves. with the
difference being that the solenoid valve integrated in the base is operated in
accordance with the control signals. Depending on the design of the process
valve, up to 3 solenoid valves can be installed in the control top.
In addition, a pneumatic NOT logic element can be used to support the
compressed air of the drive spring.
