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
MI N 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 the sufficient number of impulses
Set a bigger unit of volume or, if the connected
counting device allows it, reduce the pulse
duration value
EMPTY PI PE
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
I NPUT NOI SY
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
EXCI TATI ON FAI L
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
CURR. LOOP OPEN
The 0/ 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
ohm).
To disable the alarm,set the “mA VAL.FAULT”
value ( menu alarm ) to 0.
P.SUPPLY FAI L
Power supply different from that indicated on the label.
Verify that the power supply is that indicated on
the label
BATTERY LOW
Low voltage on battery (battery exhausted)
Replace The Battery

0040
Power supply voltage (+ 13) is too low (< 10V)
0080
Power supply voltage (+ 13) it’s too high (> 14V)
0200
timeout calibration input (input circuit is broken)
0400
I nput stage gaining is out of range
ADDRESS TO SERVI CE
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
I nterruption on the coils circuit
Check the status of the cables connecting the sensor to the converter
0C00
Cumulative alarm 0800 + 0400

0001
problem with watch-dog circuit
ADDRESSI NG TO SERVI CE
