2 Safety
2.1 Intended use
The T.VIS E-20 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.
Hint!
Correspondingly approved valve control modules and barriers must
be used for the electrical connection.
The control top T.VIS E-20 is available as
•without solenoid valve as position indicator
•with solenoid valve as control top
The control top T.VIS E-20 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.
To control different process valve functions, the T.VIS E-20 can be equipped with
up to three solenoid valves. The T.VIS E-20 is able to control a maximum of two
process valves by simultaneous actuation of a maximum of two solenoid valves.
With T.VIS E-20 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,
•coloured visualization of the valve position and status via the illuminated
dome fitted on the control top.
The control top T.VIS E-20 may be used in areas where ATEX/UKEX, IECEx and
CCCEx approval is required.
The unit can be used in potentially explosive atmospheres as indicated:

2.3 Special terms of use
Special terms of use and technical data must be observed.
Failure to observe the conditions terms of use may result in severe
explosions.
► Special conditions of use marked with the following triangle exclamation
mark must be observed.
► Additional technical data and special conditions as described in chapter 5
must be observed.
Special precautions are required to reduce the risk from electrostatic discharge. See installation/
operating instructions:
When used for a Group III (dust) application, the surface of the housing may be affected by
electrostatic charge and become a source of ignition in low relative humidity applications <~30%,
humidity if the surface is relatively free of surface contaminants, such as dirt, dust or oil.
Information on protection against ignition hazards due to electrostatic discharge can be found in
IEC EN TR50404 and IEC TS 60079-32-1. The surface should only be cleaned with a damp
cloth.
The applicable ambient temperature must be maintained by reading and understanding the user
manual, taking into account the temperature of the process medium.
The unit is designed and certified for simultaneous actuation of a maximum of two solenoid
valves. The simultaneous operation of more than two solenoid valves will increase the
temperature to a critical and non-certified level.
Cable glands are certified and specified in the test reports and must be used as intended.
The cable glands must be certified at least according to ATEX/UKEX and IECEx IP65.
Special precautions are required to reduce the risk from electrostatic discharge. See installation/
operating instructions.
