CODE ANOMALIE DESCRIPTION ACTION TO TAKE
0001 problem with watch-dog circuit
ADDRESS TO SERVICE
0002 Wrong work data configuration in eeprom
0004 Wrong safety data configuration in eeprom
0008 Defective eeprom
0010
Defective keyboard (one or more keys are pushed
during the test)
0020 Power supply voltage (+3.3) is out of range
0040 Power supply voltage (+13) is too low (<10V)
0080 Power supply voltage (+13) is too high (>14V)
0200 Timeout calibration input (broken input circuit)
0400 Input stage gaining is out of range
Check the status cables connecting the converter to the sensor, the
grounding connections or the possible presence of strong and
anomalous noise sources
0800 Interruption on the coils circuit Check the status cables connecting the converter to the sensor
0C00 Cumulative alarm 0800 + 0400 See single code

Messages, causes and corrective actions
Anomalies, codes and remedies
MESSAGE CAUSE ACTION TO TAKE
NO ALARMS All works regularly
//
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 can
not generate the sufficient number of pulses
Set a bigger volume unit 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 repeat the
empty pipe calibration procedure
INPUT NOISY
The measure is strongly effected by external noise or the
connecting cable from converter to the sensor may be broken
Check the status cables connecting the converter
to the sensor, the devices grounding connections
or the possible presence of noise sources
EXCITATION
FAIL
The coils or the cable connecting the sensor are interrupted Check the connecting cables to the sensor
CURR. LOOP
OPEN
The 4-20mA output on board or the optional one are not
correctly closed on a valid load
Verify the load is applied to the output (max 1000
Ω).
To disable the alarm, set the “mA VAL.FAULT”
value (menu alarm) to 0.
P.SUPPLY FAIL Power supply different from that indicated on the label
Verify that the power supply is as indicated on the
label
