Overtemperature protection on the analyzer unit
15.4.1
Function of the overtemperature protection
To protect the measuring system against damage caused by overheating, the analyzer unit
has a thermoelectric temperature monitor (thermostat) which acts as an overtemperature
protection device. If the temperature in the analyzer unit becomes too high, the
temperature monitor automatically switches off the measuring system and heating of the
analyzer unit.
15.4.2
Resetting the temperature monitor (after tripping)
If the temperature monitor has been tripped:
1 Leave the analyzer unit to cool.
2 Open the housing of the analyzer unit.
3 Press the reset switch on the temperature monitor ( → Fig. 31 ).
4 Close the analyzer unit.


Have the function of the temperature monitor checked at least once a year
(
