10.4 Breakdowns of the Temperature Regulators
Your analyser is fitted with a high temperature furnace which facilitates conversion in full of the carbon
contained in the sample to CO
2
without catalysts. The target temperatures of the furnace regulators are
factory-set and password-protected.
The programming of the temperature regulator may not be changed. If you have questions, please
contact your local partner or the Technical Support of LAR (Chapter 15 on page 283).
Target temperature ranges of the individual units of the analyser:
• Temperature Furnace: 1,180°C – 1,250°C
• Temperature Cooler: 4°C – 5°C

No connection between temperature
element and regulator.
• Check the electrical connections, renew
the thermocouple if required.
• If the temperature regulator is still
inactive after the thermocouple is
replaced, go to display “Service actions”
(Chapter 7.8.2 on page 118) and
activate „furnace“.
