"Mx:E:Memory
CR" The calibration parameters of the "Mx" module
are lost
→
Switch the power supply off then on
again
→
if the error originates in the M0:MAIN
board, perform a new teach-in
→
if the error originates in an "Mx" module,
calibrate the sensor connected to this
module again
→
if the error persists, return the device to
Bürkert
"Mx:E:Memory
CW"
"Mx:E:RTClock" The clock is faulty.
The process continues.
→
Return the device to Bürkert.
9.3.3. "Warning" events related to the monitoring of process
parameters (right orange leD and icons and
displayed)
When a "warning" event related to the monitoring of the process parameters is generated:
• The 4-20 mA output(s) operate normally
• The transistor outputs configured in "warning" mode switch.

in the "information"
menu meaning recommended action
"Mx:W:AIx low" 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 WARN LO
threshold defined (see chap. 8.12.2).
→
Check the wiring of the input.
→
Make sure the connected instrument cor-
rectly operates.
"Mx:W: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 WARN HIGH
threshold defined (see chap. 8.12.2).
→
Check the wiring of the input.
→
Make sure the connected instrument cor-
rectly operates.
"Mx:W:Ref imped." The impedance of the reference electrode
on the "Mx" module is out of range.
This message is displayed if monitoring
of the impedance of the reference elec-
trode 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 reference elec-
trode (chap. 8.12.4)
→
if necessary, clean the probe then recali-
brate the measurement sensor or replace
the probe.
