Possible cause Recommended action
orange 4-20 mA Switched
1)
"PULS.
OVF"
The value parametered
for the pulse output is
wrong (generated fre-
quency is > 250 Hz).
→ Increase the value of the
PU parameter (see chap.
“8.6.7”).
orange 4-20 mA Switched
1)
"NEG.
FLOW"
The measured flow rate
is negative (although the
display shows a positive
flow rate).
→ Check that the reverse fluid
circulation has no conse-
quences on the process.
→ Else, mount the device on
the pipe such as the arrow
on the housing indicates the
flow direction.
orange 4-20 mA Switched
1)
"WARN.
LOW"
The measured flow rate
is below the authorized
low limit.
This message appears
when the flow rate
is monitored (see
chap. 8.7.5).
→ Check the flow rate in the
pipe and its consequences
on the process.
→ If necessary, clean the flow
sensor then calibrate the flow
zero point.
orange 4-20 mA Switched
1)
"WARN.
HIG"
The measured flow rate
is above the authorized
high limit.
This message appears
when the flow rate
is monitored (see
chap. 8.7.5).
→ Check the flow rate in the
pipe and its consequences
on the process.
→ If necessary, clean the flow
sensor then calibrate the flow
zero point.
orange 4-20 mA Switched
1)
"DISP. OVF" The real flow rate cannot
be displayed (display is
saturated).
Except the display,
the device operates
depending on the earl
flow rate.
→ Adjust the unit or the number
of decimals in the UNIT
parameter of the Parameters
menu so that the display can
show higher values.
orange 4-20 mA Switched
1)
"LIN. LOST" The factory calibration is
lost.
The device measures
wrong values.
→ Take contact with the retailer.
orange 4-20 mA Switched
1)
"CAL. FAIL" The flow zero point cali-
bration failed.
→ Follow the calibration con-
ditions described in chap.
8.7.2.
1)
If the output is configured to switch when a warning message is generated. See chap. 8.6.5.
