Menu / Parameter Value range Description
Diagnostics / Diagnosis Control / Coating Detector (continued)
1)
Coating QE Min Alarm 0 ... 100.000
Set the minimum limit value for the electrode deposit
detection. When the smaller value, QE1 or QE2, is
undershot, an alarm is tripped.
Default setting: 0
Coating QE Max Alarm 0 ... 100.000
Set the maximum limit value for the electrode deposit
detection. When the greater value, QE1 or QE2, is
overshot, an alarm is tripped.
Default setting: 100.000
Diagnostics / Diagnosis Control / Cond. Detection
1)
Cond. Detection On / Off Activate the "Cond. Detection" function.
Default setting: Off
Important (Notice)
The conductivity measurement function can be
used in the nominal diameter range DN10 ... 300.
For further information read and observe chapter
“Extended diagnostic functions”.
One shot Cond.
The conductivity is measured cyclically at defined
intervals. Here, a current measurement can be
started.
Cond. Value Display the conductivity.
Adj. Cond. Value 5 ... 20,000 µS/cm
The conductivity must be adjusted according to the
fluid on site. The conductivity measured with a
separate meter can be entered here.
Cond. Min Alarm 5 ... 20,000 µS/cm
Set the minimum limit value for the conductivity. In the
case of undershoot an alarm is tripped.
Default setting: 5 µS/cm
Cond. Max Alarm 5 ... 20,000 µS/cm
Set the maximum limit value for the conductivity. In
the case of overshoot an alarm is tripped.
Default setting: 20,000 µS/cm
Elec. Imp. E1-GND Display only
Current impedance between electrode E1 and GND
(ground potential).
Elec. Imp. E2-GND Display only
Current impedance between electrode E2 and GND
(ground potential).
Elec. Imp Min Alarm 0 ... 20,000 Ω
Set the minimum limit value for the impedance. In the
case of undershoot an alarm is tripped.
Default setting: 0 Ω
Elec. Imp Max Alarm 0 ... 20,000 Ω
Set the maximum limit value for the impedance. In the
case of overshoot an alarm is tripped.
Default setting: 20,000 Ω
