Error code Description
The result of the selected
S098.034
Calculation type (Primary-
Secondary unit or Viceversa) is
outside its Low Saturation Limit
The result of the selected
Calculation type (Primary-
Secondary unit or Viceversa) is
outside its High Saturation Limit
The Analog Output Current could
F106.035
deviate from the correct value due
to D to A problems
Wrong device configuration could
produce a digital value that the D to
A converter cannot manage
The device continues to work
M024.036
without problems but the power
supply level is close to a threshold
that could preclude the correct
functionality
The device continues to work
without problems but the power
supply level is close to a threeshold
that could preclude the correct
functionality
The Process Pressure measured by
S051.037
the Secondary unit sensor is higher
than the acceptable mechanical
limit of the process connection
elements.
An overpressure has been detected
F103.038
by the Secondary unit sensor
The Primary unit at the start up has
F115.039
detected that the connected
Secondary unit has characteristics
not compatible with it and for this
reason the DDS system doesn't
work
The reading of the 4-20mA output
F108.040
signal is too different from what
should have been generated
The Accuracy of the D/A conversion
S022.041
could be decreased.
The Output 4/20 mA signal
representing the measure could be
not correctly compensated.
The Accuracy of the D/A conversion
M022.041
could be decreased.
The Output 4/20 mA signal
representing the measure could be
not correctly compensated.
Possible cause
The analog output for the Primary
Variable (PV) is beyond its Low
scaling limit and no longer
represents the true applied process.
The Analog Output (4-20 mA) is
saturated to the configured
Saturation Limit Low.
The analog output for the Primary
Variable (PV) is beyond its High
scaling limit and no longer
represents the true applied process.
The Analog Output (4-20 mA) is
saturated to the configured
Saturation Limit High
The D to A converter is not properly
Calibrated/Trimmed
The device is not properly
configured
The Device Power Supply is close to
the lowest acceptable limit
The Device Power Supply is close to
the highest acceptable limit
The measured process pressure
exceeds the limit of the max
working Pressure supported by the
Secondary unit. Exceeding the Max
Working Pressure can mechanically
damage the process connections
(flanges, pipes, etc) and/or be
dangerous
This effect could be produced by
other equipment on the process,
(valves, etc). Exceeding the pressure
range can cause reduced accuracy
or mechanical damage to the
diaphragm material and may
require calibration/replacement.
The Primary and Secondary units
have Different Module type or
sensor limits (Upper Range Limit)
The output circuit could be broken
or not correctly calibrated
The electronics (communication
board) temperature is out of its
lower acceptable limit.
The electronics (communication
board) temperature is out of its
higer acceptable limit.
Suggested /recommended action
Adjust the Saturation Limit or the working range
if possible.
Adjust the Saturation Limit or the working range
if possible.
Perform an Output Trimming and if the error
persist the electronics (communication board)
must be replaced
Check the Device configuration.
Check the Voltage at the terminal block and if it is
not within the valid range check the external
power supply
Check the Voltage at the terminal block and if it is
not within the valid range check the external
power supply
The compatibility of the process connection type
and material with process conditions has to be
checked. A different installation type could be
required e.g. use of remote seals.
The compatibility of pressure transmitter model
and process conditions has to be checked. A
different transmitter type could be required
Change the Secondary unit with another one
having the same sensor type (gauge or Absolute)
and with the same sensor limits of the Primary
unit
Perform an Output Trimming and if the error
persist the electronics (communication board)
must be replaced
The electronics (communication board) should be
replaced as soon as possible.
The electronics (communication board) should be
replaced as soon as possible.
