5-6 | Thermox WDG-1200/1210 Insitu 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 complet-
ing, 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 complet-
ing, 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.
