Bürkert 8619 multiCELL WM AC, Operating Instructions Manual

Page: 155 / 194

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 temperature value.
→
check whether the temperature sensor is working correctly by measuring a fluid with a known temperature. If
the temperature sensor is faulty, return the device to Bürkert;
→
if the temperature sensor is not the cause of the problem, check the process.
• The "warning" event may also be associated with one and/or other digital outputs. See section 8.10.23
• A current of 22 mA may be emitted on one and/or other of the current outputs when an "error" event related
to either the monitoring of the fluid pH, redox, conductivity or temperature values or the monitoring of an
analogue input is generated. See section 8.10.22.
• See also "If you encounter problems" in section 9.3.
STATE : Choose whether or not to activate monitoring of the fluid temperature.
This monitoring is done by the generation of a "warning" event if the fluid conductivity range defined in the "Warn
Hi/Lo" functions below is exceeded and an "error" event if the fluid conductivity range defined in the "Err Hi/Lo"
functions below is exceeded.
TEMPERATURE : Read the fluid temperature measured in real time by the temperature sensor.
WARN. HIGH : Enter the fluid temperature value above which a "warning" event is generated.
WARN. LOW : Enter the fluid temperature value below which a "warning" event is generated.
ERR. HIGH : Enter the fluid temperature value above which an "error" event is generated.
ERR. LOW : Enter the fluid temperature value below which an "error" event is generated.
