9 Advanced diagnostics functions
9.3.2
Electrode coating thresholds
Electrode deposit monitoring is disabled as a default setting and can be enabled in the "
Diagnostics/
Diagnostics Control/Coating Detector
" menu.
Recommended setting in menu "Diagnostics/Diagnostics Control/
Coationg Detector
":
•
Coating QE min. alarm = 0.5 x deposit value QE
•
Coating QE max. alarm = 2.0 x deposit value QE
9.3.3
Electrode impedance thresholds
Electrode impedance monitoring is disabled as a default setting and can be enabled in the "
Diagnostics/
Diagnostics Control/Cond. Detection
" menu.
The thresholds for the parameters "
Elect. Imp Min Alarm
" and "
Elect. Imp Max Alarm
" depend on the
conductivity of the measurement medium and must be determined on-site.
Recommended setting in menu "
Diagnostics/Diagnostics Control/Cond. Detection
":
•
Elect. imp. min. alarm = 0.2 x mean impedance value
•
Elect. imp. max. alarm = 3.0 x mean impedance value
9.3.4
Trend Logger
Recommended setting in menu "
Diagnostics/Trend
":
•
Cycle time = 43,200 minutes
Parameter
Default setting
Coating QE min. alarm
0.0 Ohm
Coating QE max. alarm
100,000 Ohm
IMPORTANT (NOTE)!
The coating value QE is the average of the startup fingerprints QE1 and QE2.
The value is determined using the following formula:
QE = (Startup Fingerprint QE1 + Startup Fingerprint QE2) / 2
Parameter
Default setting
Elect. Imp Min Alarm
0.0 Ohm
Elect. Imp Max Alarm
20,000 Ohm
IMPORTANT (NOTE)!
The mean impedance value is the value of the startup fingerprints "Elec. Imp. E1-GND" and "Elec. Imp.
E2-GND".
The value is determined using the following formula:
Mean impedance value = (startup fingerprint "Elec. Imp. E1-GND" + "Elec. Imp. E2-GND") / 2.
