Diagnostic data
The BML reports diagnostic data (events) to the controlling
system (see Tab. 7-21) or the controlling system can read
out the status using the diagnostics parameters.

Meaning
DEVICE TEMPERATURE OVERRUN (see Section 7.5.7) – The set upper temperature
warning threshold has been exceeded.
DEVICE TEMPERATURE UNDERRUN (see Section 7.5.7) – The set lower temperature
warning threshold has been undercut.
COMPONENT MALFUNCTION – Problem with the device hardware. Restart the BML by
interrupting power. If the event is repeated, the BML must be replaced.
OUT OF RANGE PLUS – The sensor head is outside the detection range. No valid data is
output. The sent process data value is 0x7FFFFFF8 resp. 2'147'483'640.
OUT OF RANGE MINUS – The sensor head is outside the detection range. No valid data is
output. The sent process data value is 0x80000008 resp. –2'147'483'640.
NO MEASUREMENT DATA – No sensor head detected. No valid data is output. The sent
process data value is 0x7FFFFFFC resp. 2147483644.
REDUNDANCY CHECK FAILED – Measuring error. Absolute value can not be correctly
processed.
MEASUREMENT DATA UNSAFE – The excess gain is too low. The application must be
checked.
TEACH IN TIMEOUT – Teach-In procedure was quit after a timeout.
