Possible problems
The primary variable has exceeded the
range points defined for the 4–20 mA
analog output signal. The analog output is
fixed at the high or low saturation point
and is not representative of the current
process conditions.
The ERS System is measuring a differential
pressure value that exceeds the configured
upper or lower alert value.
The electronics feature board in the ERS
Primary Unit has malfunctioned.
The P sensor module has failed.
HI
The P sensor module has failed.
LO
The P sensor module has failed.
HI
The P sensor module has failed.
LO
The P sensor module has detected a
HI
pressure value that exceeds the configured
upper or lower alert value.
Communication between the P-Hi sensor
module and the electronics feature board
has been lost.
The P Pressure reading has exceeded the
HI
sensor's maximum measurement range.
The P sensor module has detected a
LO
pressure value that exceeds the configured
upper or lower alert value.
Communication between the P
module and the electronics feature board
has been lost.
The P Pressure reading has exceeded the
LO
sensor's maximum measurement range.
The analog output of the ERS System is in
"fixed current mode" and is not
representative of the HART PV.
A sensor module is missing or not
detected.
Neither of the modules in the ERS System
are configured as the P sensor.
HI
Recommended actions
Verify the process conditions and modify the
Analog Range Values if necessary.
Verify the measured DP is beyond the trip
limits. If necessary, modify the trip limits or
disable the diagnostic.
Replace the electronics feature board.
Verify the P
HI
the operating limits of the sensor. Replace
the P sensor module if necessary.
HI
Verify the P
LO
the operating limits of the sensor. Replace
the P sensor module if necessary.
LO
Verify the P
HI
the operating limits of the sensor. Replace
the P sensor module if necessary.
HI
Verify the P
LO
the operating limits of the sensor. Replace
the P sensor module if necessary.
LO
Verify the measured P
the trip limits. If necessary, modify the trip
limits or disable the diagnostic.
Verify the wiring between the P
and the electronics feature board and cycle
power to the entire ERS System. Replace the
P module and/or electronics feature board
HI
if necessary.
Check the process for potential overpressure
conditions.
Verify the measured P
the trip limits. If necessary, modify the trip
limits or disable the diagnostic.
Verify the wiring between the P
sensor and the electronics feature board and cycle
LO
power to the entire ERS System. Replace the
P module and/or electronics feature board
LO
if necessary.
Check the process for potential overpressure
conditions.
Using a Field Communicator or AMS Device
Manager, disable "Loop Current Mode."
Verify that both sensors are connected and
properly wired.
Verify that both sensors are connected and
properly wired. Change the pressure
designation of one of the two modules to
"P " using a Field Communicator or AMS
HI
Device Manager.
