message dis-
played in the
"information"
menu meaning recommended action
"Mx:E:AIx high" The value of the analogue input of the
"Mx:Inputs" module is out of range.
This message is displayed if monitoring
of the analogue input is activated for the
"Mx" module, depending on the ERR HIGH
threshold defined (see chap. 8.12.2).
→
Check the wiring of the input.
→
Make sure the connected instrument
correctly operates.
"Mx:E:AIx open" An open loop has been detected on the ana-
logue input configured in voltage mode.
This message is displayed if detection of an
open loop is activated for module "Mx" (see
chap. 8.12.3).
→
Check the wiring of the input.
→
Make sure the connected instrument
correctly operates.
"Mx:E:Glass
imped." The impedance of the measurement electrode
on the "Mx" module is out of range.
This message is displayed if monitoring of
the impedance of the measurement electrode
on the "Mx" module is activated, depending
on the ERROR LOW and ERROR HIGH
thresholds defined (see chap. 8.12.4).
→
Go to the "Diagnostics" menu to read
the impedance value of the pH electrode
(chap. 8.12.4).
→
if necessary, clean the probe then rec-
alibrate the measurement sensor or
replace the probe.
"Mx:E:Ref. imped." This message is displayed if monitoring of
the impedance of the reference electrode is
activated, depending on the ERROR LOW
and ERROR HIGH thresholds defined (see
chap. 8.12.4).
→
Go to the "Diagnostics" menu to read
the impedance value of the reference
electrode (chap. 8.12.4)
→
if necessary, clean the probe then recali-
brate the measurement sensor or replace
the probe.
"Mx:E:Conductivity" The fluid conductivity is out of range.
This message is displayed if monitoring of
the fluid conductivity is activated, depending
on the ERROR LOW and ERROR 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 recali-
brate the measurement sensor
"Mx:E:Temperature" The fluid temperature is out of range.
This message is displayed if monitoring of
the fluid temperature is activated for the "Mx"
module, depending on the ERR LO and ERR
HI 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.
