1) Settings are automatically changed from warning to alarm via the parameterization method
2) The setting influences the parameters for functional safety

WARNING
In the case of devices with firmware version ≤ 02.20.04, certain messages in the
SAFETY CONFIRM. menu (increased security during parameter entry) are
automatically set from warning to alarm.
Do not use the SAFETY CONFIRM. sequence if the pressure in the applications is outside
the set current or measuring range.
‣
Standard device configuration and software/hardware locking is recommended in such
applications.
