Disassembly Procedures Read the following information carefully before disassembling a transmitter.
General information concerning the process sensor body and electrical
housing is included in the following sections.
20409 15 A Sensor module is NOT
updating
The sensor module has undergone a component or software failure.
Replace the sensor module as described on page 5-7. Contact your
Field Service Center.
20409 14 A Sensor board eeprom not
initialized, default values used
The sensor electronics has not initialized properly. Replace the sensor
module as described on page 5-7. Contact your Field Service Center.
20409 13 A Sensor microprocessor does
not respond
The sensor module has undergone a component or software failure.
Replace the sensor module as described on page 5-7. Contact your
Field Service Center.
20409 12 A Sensor board eeprom burn
failure
The sensor module has undergone a component or software failure.
Replace the sensor module as described on page 5-7. Contact your
Field Service Center.
20409 11 A Sensor hardware
incompatible with software
The sensor hardware is incompatible with the software. Replace the
sensor module as described on page 5-7. Contact your Field Service
Center.
20409 10 A Sensor CRC error (static
region)
Sensor CRC checksum failed indicating corrupted sensor module
memory. Replace the sensor module as described on page 5-7.
20409 9 A Sensor CRC error (dynamic
region)
Sensor CRC checksum failed indicating corrupted sensor module
memory. Replace the sensor module as described on page 5-7.
20409 8 Reserved NA.
20409 7 Reserved NA.
20409 6 Flash output board eeprom
soft
(recoverable) error
If this is a common error, replace the output electronics board as
described on page 5-7.
20409 5 A Flash output board eeprom
hard
(non-recoverable) error
The transmitter electronics has undergone a component or software
failure. Replace the output electronics board as described on
page 5-7.
20409 4 Flash output board eeprom
time out
If this is a common error, replace the output electronics board as
described on page 5-7.
20409 3 Reserved NA.
20409 2 A Non-volatile database CRC
error
Non-volatile database checksum failed. Attempt to restore non-volatile
database to factory defaults (see page 41 in Modbus Master
Document). If unable to restore these factory defaults, replace the
output electronics board as described on page 5-7.
20409 1 Write protect status flag Reflects write protect jumper position. No action required.
