CODES ERROR DESCRIPTIONS ACTION TO TAKE
0001 problem with watch-dog circuit
ADDRESS TO SERVICE
0002 wrong configuration work data in eeprom
0004 wrong configuration safety data in eeprom
0008 defective eeprom
0010 defective keyboard (one or more key 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) it’s too high (>14V)
0200 timeout calibration input (input circuit is broken)
0400 Input stage gaining is out of range
Check the status of the cables connecting the sensor to
the transmitter, the grounding connections of the
devices or the possible presence of strong and
anomalous noise sources
0800 Interruption on the coils circuit
Check the status of the cables connecting the sensor to
the transmitter
0C00 Cumulative alarm 0800 + 0400 see single code
ALARMS
Messages ERRORS 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 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 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 calibration procedure
BATCH ALARM
Batch interrupted for the followings condition:
‰
Timer batch expired before the end of the
batch
‰
Batch valve open and flow rate to zero for a
time longer to the safety timer set
‰
batch valve closed and flow rate different from
zero for a time longer to the safety timer set
Verify:
‰
presetting
‰
system condition
INPUT NOISY
The measure is strongly effected by external noise or the cable
connected the transmitter to the sensor is broken
Check the status of the cables connecting the sensor,
the grounding connections of the devices 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 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 FAIL Power supply different from that suitable in the label. Verify that the power supply is that suitable on label
