Bit - 0
excess_zero_co
rrection
The DP and/or SP
pressure Zero
calibration or LRV
correction performed by
the user is excessive for
the given inputs.
Perform a Reset Corrects
on the DP
and/or SP Pressure
Calibration to reset
the User calibration to
factory default. If
required, repeat the
Pressure calibrations
being careful to ensure that
input during Zero
calibration (Input Correct)
is at zero
pressure and input during
LRV calibration
(LRV Correct) matches the
configured
pressure LRV value
Bit -1
excess_span_c
orrection
The DP and/or SP
pressure URV
correction performed by
the user is
excessive for the given
inputs
Perform a Reset Corrects
on the DP
and/or SP Pressure
Calibration to reset
the User calibration to
factory default. If
required, repeat the
Pressure calibrations
being careful to ensure that
input during
URV calibration (URV
Correct) matches
the configured pressure
URV value.
Bit - 2
char_calc_error
The redundant integrity
check on the
Pressure measurement
calculation
indicates a failure.
Power Cycle the device. If
the problem
persists,replace the
Pressure module.
Bit - 3
sensor_overload
_or_fault
The Meter Body is sensing
Differential or
Static pressure greater
than the specified
limit of the Upper Range
Limit (DP URL)
Check that the process
inputs are within
specification for the
Differential and Static
Pressure for this device
input
range. Correct the
excessive pressure
input. If higher pressures
are required, a
higher range device type
may be
required. Meter Body may
have been
damaged.
Bit - 4
Sensor_RAM_D
B_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
