Burkert ELEMENT 8222 - Monitoring the Fluid Temperature

58
Adjustment and start-up
When a “warning” or “error” event is generated by the device:
→ 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 polarisation slope 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 polarisation slope.
POLARIZATION: read the current polarisation slope value.
WARN HI: enter the polarisation slope value above which a “warning” event is generated.
ERR HI: enter the polarisation slope value above which an “error” event is generated.
9.13.4 Monitoring the fluid temperature
See chpt. 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 built-in temperature probe may be shown either by too low or too high a fluid
temperature or by an incorrect temperature measurement.

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.
