Alarm Condition / Description / Corrective Action
Cell T/C Measurement Mismatch
The redundant temperature measurement does not match the real-time Thermocouple measurement.
Trigger Conditions:
• Faulty
Thermocouple
.
• Faulty
Thermocouple
circuit.
Corrective Action:
Take appropriate safety precautions, open the Analyzer door, and:
• Check the Thermocouple wiring for proper connections and inspect it for damage (cuts, nicks, burn marks,
etc.).
• Check the
Thermocouple
for proper operation.
• Check the Thermocouple circuit. Replace the Thermocouple if necessary.
Contact AMETEK to verify opera-
tion before removing the Thermocouple.
Cell Temperature Control
A critical over-temperature condition has occurred.
Trigger Conditions:
• Shorted, open, or faulty Thermocouple.
• Failed Temperature Control Circuit.
Corrective Action:
Take appropriate safety precautions, open the Analyzer door, and:
• Check the associated cables for proper connections and inspect them for damage (cuts, nicks,
burn marks, etc.).
• Check the Thermocouple for a short or open circuit. Replace the Thermocouple if necessary.
Contact AMETEK
to verify operation before removing the Thermocouple.
After this check has been made, cycle the analyzer AC power Off-On; this will reset the analyzer and
clear this alarm.
Cell Temp Rise Failure
Cell heater failed to heat the Cell.
Trigger Conditions:
• Faulty Cell Furnace Heater connection.
• Faulty Thermocouple connection.
• Faulty Cell Furnace Heater.
• Shorted Thermocouple.
Corrective Action:
Take appropriate safety precautions, open the Analyzer door, and:
• Check the associated cables for proper connections and inspect them for damage (cuts, nicks,
burn marks, etc.).
• Check the Thermocouple for a short or open circuit. Replace the Thermocouple if necessary.
Contact AMETEK
to verify operation before removing the Thermocouple.
After this check has been made, cycle the analyzer AC power Off-On; this will reset the analyzer and clear
this alarm.
