Adjustmentandstart-up
When the device generates a “warning” or “error” event:
→
go into the “Info” menu to read the cause of the event generation.
→
and/or go into the “Sensor” function of the Diagnostic menu to read the measured conductivity value.
→
if necessary, clean and/or recalibrate the conductivity sensor,
→
if necessary, check the process.
• The "warning" event may also be associated with one or other or both transistor outputs. See
chpt. 9.11.10, function "Output.TR1" or "Output.TR2".
• The "error" event may also be associated with one or other or both current outputs. See chpt. 9.11.9,
function "Output.AC1" or "Output.AC2".
• See also chpt. 10.3 Solving a problem.
ACTIVATE
: choose whether or not to activate monitoring of the fluid conductivity.
CONDUCTIVITY
: read the fluid conductivity measured in real time.
WARN HI
: enter the fluid conductivity value above which a “warning” event is generated.
WARN LO
: enter the fluid conductivity value below which a “warning” event is generated.
ERR HI
: enter the fluid conductivity value above which an “error” event is generated.
ERR LO
: enter the fluid conductivity value below which an “error” event is generated.
9.13.3 Monitoring the polarisation slope
See chpt. 9.9 to access the Diagnostic menu.
The function allows for monitoring the polarisation slope and configure the behaviour of the device if the max.
thresholds are exceeded.
A malfunction in your process or the conductivity sensor may be shown by too high a polarisation slope.

activate monitoring of the polarisation slope in the function “activate”, then
→
set a polarisation slope value above which the device generates a “warning” event and displays the icons
