3.5 Failure codes
Message Description
AWK<failure code> Critical failure – the detector is damaged – does not perform measurements.
The failure code is a hexadecimal number, the meaning of particular bits is as follows:
bit 0
bit 1
bit 2
bit 3
bit 4
bit 5
bit 6
bit 7
bit 8
bit 9
bit 10
bit 11
bit 12
bit 13
bit 14
bit 15
non-volatile memory error
incorrect values in the data block
damage of electronics
damage of electronics
negative zero drift
damage of the measurement path
damage of electronics
incorrect hardware configuration
collective critical failure – active when any AWK bit is active
damage of the measurement path
damage of the measurement path
sensor signal is too high
sensor signal is too low
damage of the temperature detector
damage of the program block
damage of the data block
AWN<failure code> Non-critical failure – malfunction of the defector that may negatively impact its
measurement accuracy (e.g. exceeding of time until periodic calibration).
The failure code is a hexadecimal number, the meaning of particular bits is as follows:
bit 8
bit 9
bit 10
bit 11
bit 13
collective non-critical failure – active when any AWN bit is active
incorrect detector supply voltage
minor negative zero drift
temperature overload
calibration time is exceeded
