Corrective actions
0x00000002 SW_DETECTED_ERR: The device software has detected
a software (typically math) error.
FAULT SFTWR Restart the transmitter.
(1)
0x00000004 COPROCESSOR_ERR: The coprocessor has detected a
math or instruction error.
FAULT COPRO Restart the transmitter.
(1)
0x00000010 INTERRUPT_ERROR: The transducer block has detected
that the coprocessor ASIC has stopped generating flow
data interrupts.
FAULT ASIC Restart the transmitter.
(1)
0x00000020 COPROC_RAM_ERR: The coprocessor has detected a
RAM error at startup.
FAULT RAM Restart the transmitter.
(1)
0x00000040 COPROC_ROM_ERR: The coprocessor has detected a
ROM error at startup.
FAULT ROM Restart the transmitter.
(1)
0x00000100 TRIGGER_OVERRANGE: The transducer has detected
that the configuration for the filter trigger level is out of
range.
Verify the filter trigger
level configuration.
Default value is 4.
0x00000200 LOW_PASS_OVERRANGE: The transducer has detected
that the configuration for the low pass filter is out of
range.
Verify the low-pass filter
configuration.
0x00000400 LOW_FLOW_CUT_OVERRANGE: The transducer has
detected that the configuration for the low-flow cutoff
is out of range.
Verify the low-flow cutoff
configuration. Optimize
filters.
0x00000800 SD2_COMM_ERR: There has been a communications
error detected in on-board messaging.
FAULT SDCOM Restart the transmitter.
(1)
0x00001000 SD2_RESET: An ASIC on the sensor board has reset. FAULT SDPLS Voltage at the transmitter
terminals should be
greater than or equal to 9
VDC. Restart the
transmitter.
(1)
0x00002000 SENSOR_PWR_FAIL: The sensor board power has failed. FAULT SPOWR Voltage at the transmitter
terminals should be
greater than or equal to 9
VDC.
0x00004000 TC_OPEN: An open circuit has been detected on the
thermocouple used to measure the process
temperature.
FAULT TC Check the thermocouple
connection to the
transmitter housing.
Replace the
thermocouple.
0x00008000 COPR_COEFF_BAD: The thermocouple math
coefficients used to calculate process temperature are
corrupt or invalid.
FAULT COEFF Replace the transmitter.
0x00100000 AMBIENT_TEMP_ALARM: The temperature of the
transmitter electronics is beyond operating limits.
FAULT TEMP Change the ambient
temperature around the
transmitter housing.
Remount the transmitter
in a different orientation
or consider a remote
mount transmitter.
