Meaning
LIMITED ACCURACY PLUS – The head is located in the detection range but outside the
set measuring range.
LIMITED ACCURACY MINUS – The head is located in the detection range but outside the
set measuring range.
OUT OF RANGE PLUS – The head is outside the detection range. No valid data is output.
The transmitted process data value is 0×7FFFFFF8 and 2'147'483'640.
OUT OF RANGE MINUS – The head is outside the detection range. No valid data is
output. The transmitted process data value is 0x80000008 and –2'147'483'640.
NO MEASUREMENT DATA – No head detected. No valid data is output. The transferred
process data value is 0×7FFFFFFC or 2147483644.
MEASUREMENT DATA UNSAFE – The function reserve is too low. The application must
be checked.
DEVICE TEMPERATURE OVERRUN (see Section 7.5.6) – The set upper temperature
warning threshold has been exceeded.
DEVICE TEMPERATURE UNDERRUN (see Section 7.5.6) – The set upper temperature
warning threshold has been underrun.
TEMPERATURE OVER RUN ERROR – The temperature has exceeded the specified
maximum temperature. The heat source must be eliminated.
HARDWARE FAULT – There is a problem with the device hardware. Interrupt power to
restart the BML. If the problem occurs again, replace the BML.
OPEN CIRCUIT AT CURRENT OUTPUT – The analog current output is open, check
installation.
