Basic safety instructions

WARNING
High operating force with pneumatic drives
Risk of injury when working on control valves due to the high operating force of the pneumatic drive.
● Please observe the corresponding safety instructions for the pneumatic actuator in use.
WARNING
Lever for position detection
Danger of crushing and shearing with mounting kits which use a lever for position detection. During commissioning and
ongoing operation, severing or squeezing of limbs could occur as a result of the lever. Risk of injury when working on
control valves due to the high operating force of the pneumatic drive.
● Do not reach into the range of motion of the lever following mounting of the positioner and mounting kit.
WARNING
Impermissible accessories and spare parts
Danger of explosion in areas subject to explosion hazard.
● Only use original accessories or original spare parts.
● Observe all relevant installation and safety instructions described in the instructions for the device or enclosed with the
accessory or spare part.
WARNING
Open cable inlet or incorrect cable gland
Danger of explosion in areas subject to explosion hazard.
● Close the cable inlets for the electrical connections. Only use cable glands or plugs which are approved for the relevant
type of protection.
WARNING
Exceeded maximum ambient or process media temperature
Danger of explosion in areas subject to explosion hazard.
If the maximum permissible ambient and process media temperatures are exceeded, the temperature class of the device is
no longer valid.
● Make sure that the maximum permissible ambient and process media temperatures of the device are not exceeded.
Refer to the information in Chapter Technical data (Page 27).
CAUTION
Influencing the position detection
Problem in the process. The position detection can be influenced by external magnetic fields or ferromagnetic parts. The
position detection displayed on the device no longer corresponds to the actual value.
● Attach the positioner in such a way that the position detection cannot be influenced by additional external magnetic
fields or ferromagnetic parts.
● For the non-initialized device, the position display shows you how the position detection is influenced by an applied
field. Move the interference source toward and away from the positioner and observe the displayed position.
