5 GEMÜ CONEXO
4.3 Function
The product is an intelligent electro-pneumatic positioner for
mounting to pneumatic actuators. It can be operated as a po-
sitioner or a process controller depending on the design.
The product is directly mounted on the actuator as standard.
The travel sensor is already integrated in the positioner (the
product can be optionally ordered with an M12 connector for
remote mounting of the travel sensor).
The travel sensor measures the current position of the valve
and reports it to the electronic system of the product, which
correlates the actual value of the valve with the set value and
adjusts the valve if necessary.
If the positioner is ordered with an additional process control-
ler (optional), a current actual value signal (e.g. level, pres-
sure, temperature, flow) is evaluated and the positioner ad-
opts the function of a process controller.
The information required can be called up on the two-line dis-
play of the product. Self-explanatory help texts that explain
the meaning of the parameters called-up are also displayed.
The product is operated locally using four keys.
4.4 Fail safe function
The product has a fail safe function, which switches the out-
puts in a controlled manner if the pneumatic air supply or the
electrical supply voltage fails (see "Fail safe function",
page 29). This fail safe function does not replace the re-
quired plant-specific safety devices. The product is not a
safety control system.

▶ These instructions are valid for devices from device ver-
sion 10. It is possible to determine which firmware has
been used on the basis of the device version. For older
devices (device version older than 10), different operating
instructions with potentially different operating specifica-
tions are used. A change to the device version can also
be due to technical changes to the hardware, which is
why several device versions describe the same firmware
version.

Order variant
In the corresponding design with CONEXO, this product has
an RFID chip (1) for electronic identification purposes. The po-
sition of the RFID chip can be seen below. The CONEXO pen
helps read out information stored in the RFID chips. The CON-
EXO app or CONEXO portal is required to display this informa-
tion.

For further information please read the operating instructions
for CONEXO products or the CONEXO datasheet.
Products such as the CONEXO app, the CONEXO portal and
the CONEXO pen are not included in the scope of delivery and
need to be ordered separately.
