2 Safety
2.1 Intended use
The T.VIS M-15 control top can be used for the pneumatic and electrical
connection of all Tuchenhagen process valves with VARIVENT adaptation. Using
the device for any other purpose is considered contrary to its designated use.
The control top T.VIS M-15 is available as
•position indicator without solenoid valve
•with solenoid valve as control top
The control top T.VIS M-15 is completely installed on the dedicated actuator/
adapter of the process valve by means of a clamp connection. Due to the internal
air guiding system, the control air can pass directly from the control top into the
actuator on suitable process valves. For process valves which do not allow the air
to be guided internally, the control top has a connection option for supplying the
air externally via a hose.
With T.VIS M-15 the following can be carried out for all valves:
•monitoring the non-actuated position of the valve disk,
•monitoring the actuated position of the valve disk,
•provision of an PNP or NPN output for feedback signals,
•coloured visualization of the valve position and status via the illuminated
dome fitted on the control top.
In addition, with T.VIS M-15 you can monitor the non-actuated position of the
double-disk with an initiator in the lantern for all double-seat valves.
The control top T.VIS M-15 may not be used in areas where ATEX approval is
required.
Hint!
The manufacturer will not accept any liability for damage resulting
from any use of the valve which is not in accordance with the
designated use of the valve. The risk is borne solely by the operating
company.

2.4 IP Protection Classes
The control top T.VIS M-15 in its standard version fulfils the requirements of
protection class IP66 (DIN EN 60529). Models in protection classes IP67 or
IP69k (both DIN EN 60529) are also available.
IP classes provide information about the degree of protection an electrical device
housing provides against the ingress of solids (first digit) or humidity (second
digit). They attempt to reproduce common kinds of failure and assign so-called IP
codes to the protected systems. The letters IP stand for 'International Protection'
and are prefixed to the code numbers.
Position of the digit Explanation
1. digit* Protection against solids
6 Dust tight
2. digit* Protection against humidity
6 Protected against powerful water jets
7Protected against temporary
immersion
9k Protected against high pressure spray
downs
*For additional digits and more detailed descriptions please refer to the
pertinent standard.
Digits not to be mentioned can be replaced by the letter x (e. g. IPx6).
Concerning the ingress of humidity, IPx6 includes all lower IP classes. This is,
however, not the case for the higher protection class IPx7!
If cleaning agents are used that significantly reduce the surface tension and/or if
high-pressure cleaners are used, we recommend using IP69k rated equipment as
an option.
Hint!
The specified IP classes only apply if the connectors are connected
correctly, if the cable gland is properly sealed and if the control top is
fitted on the valve, see Chapter 6, Page 36.

3.2 Functional description
3.2.1 Operation Principle
The control top T.VIS M-15 works with a microprocessor that contains the
software for operation, visualization and intelligent position detection.
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. A logic element NOT can
be used for pressure backup of the actuator spring. Control air is supplied to the
relevant control air chambers via air connections at the outside of the control top.
On VARIVENT valves and ECOVENT standard valves, the main control air is
guided through the switch bar. On process valves which do not allow the air to be
guided internally, the main control air is supplied to the actuator via a hose
connected to a separate air connection. The exhaust air of the main actuator is
discharged via an air connection with sound absorber or optionally via an
adjustable exhaust air throttle. Exhaust air from the optional lifting actuators is
discharged from the control top via a venting diaphragm and via a non-return
valve.
The main task of the 24 VDC interface module with its sensors is to determine
the valve position on the basis of the position of the valve stem and to generate
the corresponding feedback signals for this position in order to send them to a
higher-level control system.
Due to the illuminated dome integrated in the cap of the control top the light
emitting diodes (LED) arranged on the interface module can be seen even if the
cap is closed. The 2 differently coloured LEDs allow visualization of the main
functions of the valve.
Visualization:
•Valve in non-actuated position – green
•Valve in actuated position – yellow
•Valve deviating from its adjusted actuated positions – yellow flashing
•Valve idle – no indication
The basic 24 VDC equipment can be upgraded to the interface modules AS-
Interface or DeviveNet, simply by fitting an adapter module.
3.2.2 Control Top without Solenoid Valves
The control top T.VIS M-15 without solenoid valves works as a position indicator.
Once the two sensors have been adjusted, the control top 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
Description
Functional description
430BAL010697EN_2
15.04.2020 19

To adjust the second sensor, the process valve must be moved once to its end
positions by an external solenoid valve.
3.2.3 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.
To provide compressed air support to the actuator spring, a pneumatic NOT logic
element can be used.
The control signals are given by the user's process control system or by
operating the solenoid valves manually. To do this, use a screwdriver to turn the
