Insitu Oxygen Probes
(d) Thermocouple fault and heater above maximum limit 40.00.
The analyzer is measuring an unexpected voltage from the probe thermocouple.
CAUSE ELEMENT ACTION
1. Thermocouple open circuit. Probe Check probe wiring.
2. Thermocouple wired in reverse polarity. Wiring Check connections.
3. Thermocouple failed (very unlikely event). Probe Replace heater
- thermocouple
assembly.
(e) Cold junction temperature fault 600.0.
The analyzer is reading an unexpected voltage from starting, or correctly
completing, an auto calibration cycle.
CAUSE ELEMENT ACTION
1. Sensor not connected or incorrectly wired. Probe Check probe wiring.
2. Probe cold junction temperature too high. Probe Re-site probe or cool
connection box.
3. Sensor failed. Probe Replace sensor
diode.
(f) Failed in calibration 7000.
A fault on the system has prevented the analyzer from starting, or correctly
completing, an automatic calibration.
CAUSE ELEMENT ACTION
1. Zero gas pressure not detected. ACU Ensure zero cal gas
is connected and
turned on.
2. Any previous fault See appropriate fault
section.
