Table 4.2 List of warnings
The LRV setting is lower than the temperature
range (GS stated value).
The LRV setting is higher than the
temperature range (GS stated value).
The URV setting is lower than the temperature
range (GS stated value).
The URV setting is higher than the
temperature range (GS stated value).
The LRV and URV settings are reversed.
The setting is lower than the recommended
minimum span.
There is a problem with input (setting status)
specified to SV map.
There is a problem with input (setting status)
specified to TV map.
There is a problem with input (setting status)
specified to 4V map.
Sensor1 input temperature is lower than the
temperature range. The measurement range
is a YTA series specification but not a range
defined by sensor type.
Sensor1 input temperature is higher than the
temperature range. The measurement range
is a YTA series specification but not a range
defined by sensor type.
Sensor2 input temperature is lower than the
temperature range. The measurement range
is a YTA series specification but not a range
defined by sensor type.
Sensor2 input temperature is higher than the
temperature range. The measurement range
is a YTA series specification but not a range
defined by sensor type.
The EEPROM checksum field is using the
spare 4 (the last area). This means there is no
spare area for writing the EEPROM
checksum.
Output reverse mode operation is ongoing.
Forced output mode is on.
In this case, the forced output is active or
the output adjustment is performed.
The sensor backup mode is set.
This is the parameter write enable status.
Unexpected write cannot be prevented.
Check the LRV setting.
Check the LRV setting.
Check the LRV setting.
Check the URV setting.
Set LRV < URV.
Set URV-LRV to be set to greater than minimum
span.
Correct SV mapping
Correct TV mapping
Correct 4V mapping
Check process temperature and set new LRV and
URV values. Verify correct sensor selection for
temperature range.
Check process temperature and set new LRV and
URV values. Verify correct sensor selection for
temperature range.
Check process temperature and set new LRV and
URV values. Verify correct sensor selection for
temperature range.
Check process temperature and set new LRV and
URV values. Verify correct sensor selection for
temperature range.
There is no problem with current operation. If
EEPROM is damaged an EEPROM FAILURE will
be indicated.
Turning output reverse mode OFF causes normal
output .
The transmitter is in manual output mode. Return
to normal operation if desired.
Turn the sensor backup mode OFF.
Set the protect parameter to YES to enable write
protect mode and prevent unexpected changes.
