Protective equipment
4.5 Thermal cutoff
The tripping temperature of the thermal cutoff is 72°C.
When tripped, the thermal cutoff separates the 24 V voltage supply from the
solenoid valves. The device is separated from the combustion gas. Solenoid valves
are closed in the current-free state.
4.6 Solenoid valve
Should combustion malfunctions occur or the overpressure be insufficient, the
solenoid valves at the combustion gas inlet of the combustion calorimeter close. A
restart of the combustion calorimeter is necessary.
