What happens when the optical sensor in a pellet system detects an absence of flame?

When the optical sensor in a pellet system detects an absence of flame, it triggers an automatic shutdown of the system. This safety feature is essential to prevent dangerous situations such as excess fuel accumulation, which could lead to potential fire hazards or system malfunctions. The optical sensor continuously monitors the presence of a flame to ensure that combustion is occurring as intended. If a flame is not detected, the system interprets this as a potential failure and responds by shutting down to protect users and property.

The design of these systems prioritizes safety, and the automatic shutdown mechanism helps to mitigate risks associated with incomplete combustion or fuel feed issues. Thus, the pellet system is engineered to halt operation when flame detection is compromised, ensuring that any underlying issues can be addressed safely.
