Details of
Critical
Fault
Meterbody
Failure
Pressure module is
reporting a critical
failure of the
pressure sensing
measurement within
the Meter Body,
which may be
caused by one of the
following:
• Meter body failure
• Sensor firmware
flow failure
Power cycle the
device. If the problem
persists, replace the
Meter Body
Bit - 0

Sensor
Charactarization
corrupt
Pressure module is
reporting corruption
in the Pressure
Characterization data
Power cycle the
device. If the problem
persists, replace the
Meter Body
Bit -1
Pressure
Suspect Input
Differential Pressure,
Meter Body
Temperature and/or
Static Pressure input
are extremely out of
range such that the
value is suspect.
Verify that all inputs
are within
specifications. Power
cycle the device. If
the problem persists,
replace the Meter
Body.
Bit - 2
Sensor RAM DB
Fault
Pressure module is
reporting corruption
in the database in the
Random Access
Memory (RAM)
Power cycle the
device. If the problem
persists, replace the
Meter Body
Bit - 3
Pressure NVM
Corrupt
Pressure module is
reporting corruption
of the Non-Volatile
Memory data (NVM)
Power cycle the
device and if fault is
cleared ensure to
configure sensor
parameters. If the
problem persists,
replace the Meter
Body

Corrupt
Pressure module is
reporting corruption
in the Random
Access Memory
(RAM)
Power cycle the
device. If the problem
persists, replace the
Meter Body
Bit - 5
Sensor Code
Corrupt
Pressure module is
reporting corruption
in sensor firmware
Power cycle the
device. If the problem
persists, replace the
Meter Body
Bit - 6
Sensor Flow
Failure
Pressure module
firmware Program
Flow Failure. This
fault will get set if any
of the critical part of
the code is not
executed after
expected duration.
Power cycle the
device. If the problem
persists, replace the
Meter Body
Bit - 7
Sensor Input
Failure
The temperature
sensor
(Thermocouple or
RTD) has an open
input. The sensor
connections may
be disconnected or
broken.
Check the
temperature sensor
connections for
disconnections or
broken wires. Repair
the sensor
connections
