Burkert 8228 ELEMENT - Monitoring the Fluid Temperature

61
Operating and commissioning
Type 8228
When the device generates a "warning" or an "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 both transistor outputs (see chap. 9.11.10, function
"Output.TR1" or "Output.TR2").
• The "error" event may also be associated with one or both current outputs (see chap. 9.11.9, function
"Output.AC1" or "Output.AC2").
• See also chap. "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 fluid temperature
See chap. 9.9 to access the Diagnostic menu.
The function allows for monitoring the fluid temperature and configure the behaviour of the device if the param-
etered ranges are exceeded.
A malfunction in your process or the conductivity sensor may be indicated either by too low or too high a
measured fluid temperature.

To be warned when the fluid temperature is too low or too high:
→ activate monitoring of the fluid temperature in the function “activate”, then
→ set a temperature range (in °C) outside of which the device generates a “warning” event and displays the
and
icons.
→ set a temperature range (in °C) outside of which the device generates an “error” event and displays the
and
ERR
icons.
