4 Product description
4.3 Function
The product is an intelligent electro-pneumatic positioner for
mounting to pneumatic linear and quarter turn actuators.
The positioner can be directly mounted to the actuator using a
suitable mounting kit. The mounting kit contains both the
mounting bracket and adapter and the appropriate travel
sensor with the corresponding fixing screws.
Remote mounting is also possible. The mounting bracket/ad-
apter are not required for this.
The travel sensor measures the current position of the valve
and reports it to the product's electronic system. The elec-
tronic system then compares the actual value of the valve
with the set value specified and readjusts the valve in the
event of a system deviation.
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.
Operation is carried out using the four keys.
4.4 Fail safe function
The product has a fail safe function which ensures that the
outlets are controlled during a pneumatic and electrical power
supply failure. The behaviour depends on the design. A safety
reaction also ensures that the valve is controlled in the event
of a signal error. This fail safe function is not a substitute for
specific plant safety requirements. The product is not a safety
control system.

NOTICE
Device version
▶ 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 tech-
nical changes to the hardware, which is why several
device versions can contain the same firmware version.
