Error code Displayed message
S044.043 MV Calculation out of Range
S052.031 Max operating pressure
Exceeded
S054.006 Sensor Temperature Out of
Limits
Change from one to two columns
Possible cause
Flow is outside of the range.
The volume flow is outside of the range.
The heat flow is outside of the range.
The calculated fill height is outside of the range.
The volume is outside of the range.
The mass is outside of the range.
The static pressure of the process increases the
maximum permissible operating pressure for the
transmitter. Exceeding the maximum operating
pressure can entail mechanical damage on the
process connections (flanges, pipes, etc.) or
cause dangerous situations.
The temperature of the process environment
influences the pressure transmitter. Excess
temperatures can reduce accuracy, impair device
components, and make a calibration or
replacement necessary.
Recommended measure
Compare the settings of the multivariable configuration with the
process conditions.
You must check whether the pressure transmitter is suitable for
the process conditions.
You must check whether the pressure transmitter is suitable for
the process conditions. A different type of installation could be
necessary, for example use of diaphragm seals.
