Bringing into service
Conductivity controller LRR 1-50: Setting switchpoints and parameters
Setting the MAX switchpoint
Action
Function
Select parameter AL.Hi, enter and save the desired conductivity. The MAX switchpoint is set between
1 and 5000 ppm or 1 and 9999 µS/cm.
Setting the set point
Select parameter SP, enter and save the desired conductivity.
The set point is set between
1 and 5000 ppm or 1 and 9999 µS/cm.
Setting the reset hysteresis
Select parameter HySt, enter and save the required value.
The reset hysteresis is set between 1
and 25% of the set point.
Conductivity electrode LRG 1-.: Setting the correction factor
Select correction factor CF, enter and save the
required value.
Alternatively, use calibration function CAL
(from software version “S-13” onward).
Once service temperature is reached, measure the con-
ductivity of a water sample [at 77 °F (25 °C)]. Change
the correction factor in increments until the indicated
actual value matches the reference reading. This adapts
the conductivity measurement to the specific conditions
of the installation, or compensates for deviations during
operation.
Conductivity electrode LRG 16-9
Switching on temperature compensation
Select setting inP and turn the rotary knob
clockwise. YES appears. Save the setting.
Setting the temperature coefficient
Select temperature coefficient tC, enter and
save the desired percentage.
Once service temperature is reached, measure the con-
ductivity of a water sample [at 77 °F (25 °C)]. Change the
temperature coefficient in increments until the indicated
actual value matches the reference reading.
If necessary:
Select correction factor CF, enter and save the
required value.
Alternatively, use calibration function CAL
(from software version “S-13” onward).
During operation, the indicated conductivity may differ
from the reference reading, e.g., due to dirt deposits. In
this case, change the correction factor in increments until
the indicated actual value matches the reference reading.
Setting the actual value output-current output standardization
Select parameter Sout, enter and save the
desired conductivity.
The current output is set between
5 and 5000 ppm (10 and 9999 µS/cm)
Setting the flushing interval and flushing time
Select parameter Si, enter and save the desired
time.
The flushing interval is set between 0 and 24 hours.
Select parameter Sd, enter and save the de-
sired time.
The flushing time is set between 1 and 4 minutes.
