Function Check 
PRTB NormalMode = AUTO and PRTB
TargetMode != AUTO
Sensor Invalid 
The transducer is not able to generate a
valid signal due to one of the following
conditions (see RB_EXTENDED_ACTIVE)

The primary signal of the sensor is no longer
available
Sensor Memory Fail 
The data in the sensor memory are
corrupted precluding the correct
functionality of the device

The sensor and the connected electronics are
incompatible
Memory Failure 
The device data loaded at the start up are
corrupted precluding the correct
functionality of the device
P-dP Sensor Fail 
The sensor signal value is incorrect due to a
mechanical failure i.e. Loss of fill fluid from
the cell; ruptured diaphragm, broken
sensor…
Static Pressure Sensor Fail 
The sensor signal value is incorrect due to a
mechanical failure i.e. The circuitry for the
sampling of the static pressure has failed...
Valid for Differential pressure models
Sensor Temperature Fail 
The circuitry for the sampling of the
temperature has failed. The measurement
accuracy is decreased more than the
acceptable error
Pressure Overrange 
The Pressure is outside the overpressure
limit and risk to damage the sensor
P-dP Out Of Limit 
The measured Process Pressure is outside
the sensor limits and no longer representing
the true applied process value
Static Pressure Out Of Limit 
The measured Static pressure is above its
operational limit
Input Simulation Active 
The Input Simulation function is Active At
least one of these variables is simulated

The Pressure Value produced in output is
calculated starting from a simulated input

The Static Pressure Value produced in output is
calculated starting from a simulated input

The Sensor Temp Value produced in output is
calculated starting from a simulated input
Sensor Temperature Out Of
Limit

The measured sensor temperature is
outside of its operational limits
Max. Working Pressure
Exceeded

The measured Static Pressure is higher than
the acceptable mechanical limit of the
process connection elements.
Primary Variable Out of Range 
Process value is outside its High or Low
working range
