orange Switched 2) "WARN. LOW" During dosing, the measured
flow rate has stayed under the
minimum threshold for the set
time delay.
This message appears when
the flow rate is monitored (see
chap. 9.8.4).
→
Check the flow rate in the pipe
and its consequences on the
process.
→
If necessary, clean the flow
sensor.
→
When the dosing is finished,
access the Information menu
and confirm the message. See
chap. “9.10”.

flow rate has stayed above the
maximum threshold for the set
time delay.
This message appears when
the flow rate is monitored (see

→
Check the flow rate in the pipe
and its consequences on the
process.
→
If necessary, clean the flow

correctly corrected and the
dosed quantity has exceeded
the threshold set in the overfill
correction parameter (see
chap. “9.7.15”).
→
Chek the process, and espe-
cially for the flow rate being
stable.
→
Check the last dosing (missing
liquid or overfilling).
→
If the problem occurs again
after several dosings, use
the function to smoothen the
overfill correction. See chap.
“9.7.15”.
→
Access the Information menu
and confirm the message. See
chap. “9.10”.
