Commissioning/Setup Mode
For commissioning, the following principles apply:
•Take protective measures against dangerous contact voltages in accordance with
pertinent regulations.
•The control top must be completely assembled and correctly adjusted. All screw
connections must be securely tightened. All electrical cables must be installed
correctly.
•Reliably secure machine parts which have already been connected against inadvert-
ently being switched on.
•After conversion of the control top, residual risks must be reassessed.
NOTE
The two sensors in the control top and the optional external sensor in the lantern are set
to the factory settings and must therefore be adjusted in accordance with the chapter
entitled “Setting into Operation“ (page 50). The manufacturer will not accept any liability
for malfunctions. The risk of such misuse lies entirely with the operator of the facility.
Setting into Operation
For setting into operation, the following principles apply:
•Only allow properly qualified staff to set the control top into operation.
•Establish all connections correctly.
•The safety devices for the control top must be complete, fully functional and in
perfect condition. Check the function before starting any work.

Residual Dangers
Dangerous situations can be avoided by safety-conscious and proactive behaviour of
the staff and by wearing personal protective equipment.
Electrostatically Endangered Components and 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.
To minimize or prevent the possibility of damage resulting from sudden electrostatic
discharge,
•observe the requirements of DIN EN 61340-5-1 and 5-2 and
•take care not to touch the electronic components!
Residual dangers on the control top and measures
Danger Cause Measure
Danger to life Inadvertent switch-on of the
control top
Effectively disconnect all components, effec-
tively prevent switch-on.
Electric power Observe the following safety rules:
1Isolate from the power supply.
2Take appropriate measures to prevent switch
on.
3Test absence of voltage.
4Earthing and short-circuiting.
5Cover or safeguard any adjacent live parts.
Damage to prop-
erty
Welding work can damage
electronics or cause loss of
data.
Do not carry out any welding work in the vicinity
of the control top or protect electronics profes-
sionally.

Transport and Storage
Storage
Transport and Storage
Scope of Supply
On receipt of the control top check whether
•the details on the type plate correspond to the data in the order and delivery docu-
ments,
•the equipment is complete and all components are in good order.
Transport
For transport, the following principles apply:
•Only use suitable lifting gear and slings for transporting the package units/control
modules.
•Observe the pictograms on the package.
•The synthetic materials of the control tops are susceptible to breaking. Take care
when transporting the control top. Do not grip sensitive parts of the unit to lift or push
the unit or to support yourself.
•The permanent magnet on the switch bar is fragile and must therefore be protected
against mechanical impact.
Storage
If, during transport or storage, the control top is going to be exposed to temperatures ≤0
°C, the control top must be dried and suitable measures be taken to protect it from
damage.
NOTE
We recommend that the unit should be stored at a temperature of ≥5 °C for a period of
24 hours prior to any handling so that any ice crystals formed by condensation water
can melt.

Operating Instructions · Control Top T.VIS® M-15
Edition 2017-10-16
Intended Purpose
Designated 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 T.VIS M-15 control top is available as
•position indicator without solenoid valve
•control top with solenoid valve
The complete T.VIS M-15 control top is mounted on the actuator/adapter of the process
valve provided for this purpose using 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.
T.VIS M-15 allows the following on 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.
T.VIS M-15 in addition allows on all double-seat valves the non-actuated position of the
double-disk to be monitored via a proximity switch in the lantern.
