4.8 Thermal fuse
NOTE
The initiation temperature of the thermal fuse is 72°C.
Upon initiation, the thermal fuse disconnects the 24 V voltage supply.
4.9 Solenoid valve
In case of faults, the solenoid valves of the combustion calorimeter close automat-
ically. The combustion calorimeter then needs to be restarted.
4.10 Fan
The fan mixes the exhaust gases generated in the combustion with fresh air and
ensures an appropriate volume flow. The rotational speed of the combustion calo-
rimeter is monitored. In case of a fan failure, the combustion calorimeter enters a
safe state.
