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!
If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.
