Safety instructions

CAUTION
Risk of injury due to incorrect parameter values!
Incorrect parameter values can cause the valve to move
unexpectedly. This can lead to process failures and result in
injuries.
• Before recommissioning a positioner that was previously
in use at another location, always reset the device to its
factory settings.
• Never start automatic adjustment before restoring the
factory settings!
Note
Before assembly, check whether the positioner meets the
control and safety requirements for the installation location
(actuator or final control element).
Refer to the Specification in the data sheet.
Only qualified specialists who have been trained for these tasks
are authorized to mount and adjust the unit, and to make the
electrical connection.
When carrying out any work on the device, always observe the
local accident prevention regulations and the regulations
concerning the construction of technical installations.
