The Replace operation is required
after the changing of the
electronics or of the sensor The electronics (communication
board) or the Sensor have been
changed but the replacement
operation has not been executed "The replacement operation must be executed:
-Move the SW 1 of the electronics (communication
board) in position 1 = Enable replace mode
-Select the SW 2 the element that has been
changed between new Sensor or new electronics
(communication board)
-Power Cycle the device
-Move the SW 1 of the electronics (communication
board) in position 0"
no effect
The Replace operation is required
after the changing of the
electronics or of the sensor The electronics (communication
board) or the Sensor have been
changed and a replacement
operation for a new sensor has to
be executed. "The replacement operation must be executed:
Only the data of the electronics (communication
board) can be copied into the sensor
-Move the SW 1 to Enable replace mode (1)
-Select with the SW 2 to New Sensor (1)
-Power Cycle the device
-Move the SW 1 to Disable replace mode (0)
"
no effect
The Replace operation has been
attempted but with wrong direction The electronics (communication
board) or the Sensor have been
changed, The replacement has been
enabled but with a wrong direction
(SW 2 = 0)
"Change the replacememt direction (if possible)
-The SW 1 is already set to Enable replace mode
(1)
-Select with the SW 2 to New Sensor (1)
-Power Cycle the device
-Move the SW 1 to Disable replace mode (0)

F105.043
The Accuracy of the D/A conversion
could be decreased.
The Output 4/20 mA signal
representing the measure is
compensated to the last valid
temperature
The circuitry for the sampling of the
electronics (communication board)
temperature has failed. The electronics (communication board) should be
replaced as soon as possible. UP/DW ALARM
F117.044
The data in the Secondary unit
sensor memory are corrupted
precluding the correct functionality
of the device Secondary unit Sensor memory
corrupted The Secondary unit Sensor must be replaced UP/DW ALARM
M027.045
The device continues to work
without problems but the new
settings for the Secondary unit
sensor can be lost after a power
cycle because the backuped
configuration is not updated Writings to the Secondary unit
Sensor non-Volatile Memory was
not successful The Secondary unit Sensor should be replaced as
soon as possible. no effect
F119.046
The Basic signal of the Secondary
unit sensor is no longer available.
The transducer is not in a condition
to generate a valid signal. The sensor signal of the Secondary
unit is not being updated correctly
as a result of electronics
(communication board) failure,
sensor error or a poorly connected
sensor cable. Check cable connection, check sensor and if
problem persists, the Secondary unit sensor must
be replaced. UP ALARM
