Problem Recommended action
any colour 4 mA depending on
the thresholds
or switched
1)
The current output
transmits 4 mA
whatever the displayed
flow rate value.
Check the configuration of the current
output. See chap. “8.6.6”.
any colour 20 mA depending on
the thresholds
or switched
1)
The current output
transmits 20 mA
whatever the displayed
flow rate value.
Check the configuration of the current
output. See chap. “8.6.6”.
any colour 22-30 mA depending on
the thresholds
or switched
1)
The current output
transmits a value
between 22 and
30 mA.
Switch the device power supply off then
on.
If the problem occurs again, take contact
with the retailer.
any colour 30 mA depending on
the thresholds
or switched
1)
The current output
transmits a value >
30 mA.
Check the wiring of the current output.
If the problem occurs again, take contact
with the retailer.
any colour 4-20 mA depending on
the thresholds
or switched
1)
The current value trans-
mitted on the AO1
current output does not
correspond to the dis-
played flow rate.
Check the configuration of the current
output. See chap. “8.6.6”.
Check the OFFSET and SPAN param-
eters of the current output. See chap.
“8.7.1”.
any colour 4-20 mA The DO2 and DO3 outputs do not
switch whatever the displayed flow rate
value.
Check the parameters of the DO2 and
DO3 relay outputs. See chap. “8.6.11”.
Check the flow rate unit.
Check the behaviour of the outputs. See
chap. “8.7.3”.
1)
If the output is configured to switch when a warning message is generated. See chap. 8.6.5.
