HMI code Description
The measured Process Pressure
value is outside the sensor limits
F102.004
and no longer representing the true
applied process value.
The measured Static pressure is
F100.005
above its operational limit
The measured sensor temperature is
S054.006
outside of its operational limits
The measured Static Pressure is
higher than the acceptable
M052.031
mechanical limit for the process
connection elements.
Process value is outside its working
S050.010
range
PILD algorithm has detected both
impulse lines plugged.
PILD algorithm has detected a
plugged impulse line on the HIGH
side.
M018.008
PILD algorithm has detected a
plugged impulse line on the LOW
side.
PILD algorithm has detected one
plugged impulse line.
The pressure value currently
M016.009 detected is too different from what
used for the PILD Training
Transducer Block is Out of Service.
Possible Cause
The measurement range has not
been correctly calculated OR an
incorrect transducer model has
been selected.
The static pressure of the process
exceeds the limit of the sensor.
Exceeding the Static Pressure can
reduce accuracy, mechanically
damage the diaphragm and may
require calibration/replacement. An
incorrect transducer model could
have been selected.
The temperature of the process
environment affects the pressure
transmitter; Excess temperature can
reduce accuracy, degrade device
components and may require
calibration/replacement.
The static pressure of the process
exceeds the limit of the max working
Pressure supported by the
transmitter. Exceeding the Max
Working Pressure can mechanically
damage the process connections
(flanges, pipes....) and/or be
dangerous
The measured pressure value is
beyond its Low or High scaling limits
Both connections between the
pressure sensor and the process are
blocked either by plugging or closed
valves.
The connection between the
pressure sensor and the process on
the HIGH side is blocked either by
plugging or closed valves.
The connection between the
pressure sensor and the process on
the LOW side is blocked either by
plugging or closed valves
One of the connections between the
pressure sensor and the process is
blocked either by plugging or closed
valves.
Process conditions have changed to
an extent that new settings for the
PILD algorithm are needed.
Power has been reapplied resulting
in the re-initialization of the device.
Suggested Actions
The compatibility of pressure
transmitter model and process
conditions has to be checked.
Probably a different transmitter
type is required.
The compatibility of pressure
transmitter model and process
conditions has to be checked.
Probably a different transmitter
type is required.
The compatibility of pressure
transmitter model and process
conditions has to be checked. A
different installation type could be
required e.g. use of remote seals.
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.
Adjust the working range if possible.
Check valves and impulse line. Clean
impulse line if necessary and initiate
PILD training
A new Training is necessary for this
new process condition
Check transducer block
configuration and make sure that
the Target Mode has been set to
Automatic Mode.
