Emerson 8800A, Product Manual

Page: 141 / 160

C-9
HART Communicator
The following error/warning messages are applicable only to
the Model 8800C and Model 8800A Vortex Flowmeters.
Message Description
ROM CHECKSUM ERROR The EPROM memory checksum test has failed. The transmitter will
remain in ALARM until the ROM checksum test passes.
EEPROM CHECKSUM ERROR The User Configuration area in Nonvolatile EEPROM memory has
failed the checksum test. It is possible to repair this checksum by
verifying and reconfiguring ALL transmitter parameters. The
transmitter will remain in ALARM until the EEPROM checksum test
passes.
RAM TEST ERROR Transmitter RAM memory test has detected a failed RAM location.
The transmitter will remain in ALARM until the RAM test passes.
ASIC INTERRUPT ERROR This error is not currently used in the Model 8800C. It should not
appear on the 275.
DIGITAL FILTER ERROR The digital filter in the transmitter electronics is not reporting. The
transmitter will remain in ALARM until the digital signal processor
resumes reporting flow data.
COPROCESSOR ERROR If this occurs at power-up, the RAM/ROM test in the coprocessor has
failed. If this occurs during normal operations, the coprocessor has
reported either a math error or a negative flow. This is a FATAL error
and the transmitter will remain in ALARM until reset.
SOFTWARE DETECTED ERROR The software has detected corrupted memory. One or more of the
software tasks has corrupted memory. This is a FATAL error and the
transmitter will remain in ALARM until reset.
ELECTRONICS FAILURE This is a summary error indication. This error will be reported if any of
the following error conditions are present:
1. ROM Checksum Error
2. EEPROM Checksum Error
3. RAM Test Error
4. ASIC Interrupt Error
5. Digital FIlter Error
6. Coprocessor Error
7. Software Detected Error
TRIGGER LEVEL OVERRANGE The trigger level in the transmitter digital signal processing has been
set beyond its limit. Use manual filter adjustment to “Increase
Filtering” or “Increase Sensitivity” to bring the trigger level back within
range.
LOW PASS FILT OVERRANGE The low flow cutoff in the transmitter digital signal processing has
been set beyond its limit. Use manual filter adjustment to “Increase
Range” or “Decrease No Flow Noise” to bring the low flow cutoff
adjustment back within range.
AMBIENT TEMP OVERRANGE The electronics temperature sensor within the transmitter is reporting
a value out of range.
PARAMTERS NOT CONFIGURED Certain configuration parameters are out of range. either they have
not been properly configured, or they have been forced out of range
as a result of a change to a related parameter. For example: When
using mass flow units, changing the process density to a value too
low could push the configured Upper Range Value beyond the sensor
limit. In this case, the Upper Range Value would need to be
reconfigured.
FACTORY EEPROM
CONFIG ERROR The factory configured values in non-volatile EEPROM memory have
become corrupted. This is a FATAL error. The transmitter will remain
in ALARM until reset.
