Message Cause Action to take
MAX ALARM The flow rate is higher than the maximum threshold set Check the maximum flow rate threshold set and the process conditions
MIN ALARM The flow rate is lower than the minimum threshold set Check the minimum flow rate threshold set and the process conditions
FLOW RATE >FS The flow rate is higher than the full scale value set on
the instrument
Check the full scale value set on the instrument and the process
conditions
PULSE/FREQ>FS The pulse generation output of the device is saturated
and cannot generate
Set a bigger unit of volume or, if the connected counting device allows
it, reduce the pulse duration value
EMPTY PIPE The measuring pipe is empty or the detection system
has not been properly calibrated
Check whether the pipe is empty or perform again the empty pipe
function calibration procedure
INPUT NOISY The measure is strongly effected by external noise or
the cable connected the converter to the sensor is
broken
Check the status of the cables connecting the sensor to the converter,
the grounding connections of the devices or the possible presence of
strong and anomalous noise sources
EXCITATION FAIL The coils or the cable connecting the sensor to the
converter are interrupted
Check the status of the cables connecting the sensor to the converter
CODES ANOMALIE DESCRIPTIONS ACTION TO TAKE
0001
problem with watch-dog circuit
0002 wrong configuration work data in eeprom
0004 wrong configuration safety data in flash eeprom
0008
defective eeprom
0010
defective keyboard (one or more key are pushed
during the test)
0020 reference voltage out range
0040 Power supply voltage (+13) is too low (<10V)
0080 Power supply voltage (+13) it’s too high (>14V)
0100 initialization error ADC primary of system
0200
timeout calibration input (input circuit is
broken)
ADDRESSING TO SERVICE
0400 Gain input stage is out range
Check the status of the cables connecting
the sensor to the converter, the grounding
connections of the devices or the possible
presence of strong and anomalous noise
sources
0800 Interruption coils circuit
Check the status of the cables connecting
the sensor to the converter
