message displayed
in the "information"
menu meaning recommended action
"Mx:W:Glass
imped." The impedance of the measurement elec-
trode on the "Mx" module is out of range.
This message is displayed if monitoring
of the impedance of the measurement
electrode is activated on the "Mx" module,
depending on the WARNING LOW and
WARNING HIGH thresholds defined (see
chap. 8.12.4).
→
Go to the "Diagnostics" menu to read
the impedance value of the measurement
electrode (chap. 8.12.4).
→
if necessary, clean the probe then recali-
brate the measurement sensor or replace
the probe.
"Mx:W:Conductivity" The fluid conductivity is out of range.
This message is displayed if monitoring of
the fluid conductivity is activated on the
"Mx" module, depending on the WARNING
LOW and WARNING HIGH thresholds
defined (see chap. 8.12.5).
→
Go to the "Diagnostics" menu to read the
fluid conductivity value (chap. 8.12.5)
→
if necessary, clean the cell then recalibrate
the measurement sensor
"Mx:W:Temperature" The fluid temperature is out of range.
This message is displayed if monitoring of
the fluid temperature is activated on the
"Mx" module, depending on the WARNING
LOW and WARNING HIGH thresholds
defined (see chap. 8.12.6).
→
Go to the "Diagnostics" menu to read
the value of the temperature measured
(chap. 8.12.6).
→
If necessary, check whether the tem-
perature sensor is working correctly
by measuring a fluid with a known
temperature.
→
If the temperature sensor is faulty, return it
to the manufacturer.
→
if the temperature sensor is not the cause
of the problem, check the process.
9.3.4. "Warning" events related to a problem with the device (left
orange leD and icons and displayed)
When a "warning" event related to a problem with the device is generated:
• The 4-20 mA output(s) operate normally
• The transistor outputs configured in "warning" mode switch.
message dis-
played in the
"information"
menu meaning recommended action
"M0:W:Time lost" The date and time are lost.
→
Set the date and time again (see chap. )
"M0:W:ON/OFF
time" The duration defined in the parameter "Max-
ONtime" in the ON/OFF function has been
exceeded (see chap. 8.10.11)
→
Deactivate then reactivate the ON/OFF
function
"M0:W:Pulse x
lim." In "Pulse" mode, the volume entered for a
pulse is incorrect (see page 78).
→
Enter an appropriate volume
→
check the K factor.
