Monitoring The Conductivity Of The Fluid - Burkert 8619 Operating Instructions Manual

Type 8619
Diagnostics Menu
STATE: Choose to activate or deactivate monitoring of the impedance of the electrode selected.
This monitoring is done by the generation of a "warning" event if the impedance range defined in the "Warn
Hi/Lo" functions below is exceeded and an "error" event if the impedance range defined in the "Err Hi/Lo"
functions below is exceeded.
IMPEDANCE: Read the impedance, measured in real time, on the electrode selected.
TEMP. DEPEND. : Temperature coefficient of correction for the impedance measurement of a fluid. The
default coefficient is valid for probes sold by Bürkert
WARN. HIGH: Enter the impedance value above which a "warning" event is generated.
WARN. LOW: Enter the impedance value below which a "warning" event is generated.
ERR. HIGH: Enter the impedance value above which an "error" event is generated.
ERR. LOW: Enter the impedance value below which an "error" event is generated.

Monitoring the conductivity of the fluid

This function is used to monitor the fluid conductivity and define the device's behaviour if the ranges
defined are exceeded.
Refer to section 8.10 to access the "Diagnostics" menu.
Diagnostics
Mx:Conductivity
A malfunction in your process or on the measurement cell may be revealed by too low or too high a fluid
conductivity.
To be warned when the conductivity is out of range:
→ activate monitoring of fluid conductivity in the "Status" function, and then
→ set a fluid conductivity range outside of which the 8619 generates a "warning" event and displays the
icons and .
→ set a fluid conductivity range outside of which the 8619 generates an "error" event and displays the
X
icons and .
When a "warning" or "error" event is generated by the 8619:
→ go into the "Information" menu to read the cause of the event generation
→ and/or read the measured conductivity value.
→ If necessary, clean the cell and/or recalibrate the sensor.
→ If necessary, check the process.
