Lockout protection trips the boiler when a monitored safety condition indicates unsafe operation. The most common triggers are tied to the core safety systems: flame failure, which means the burner isn’t producing a stable flame and fuel should be shut off to avoid dangerous unburned fuel buildup; low water or low water flow, which can lead to overheating and damage if the boiler is not adequately cooled; and high pressure, which signals the system is under unsafe pressure and must be shut down to prevent equipment failure. Electrical power fluctuation, while disruptive to controls, isn’t a direct indicator of unsafe combustion or process conditions. It affects the control power or sensors rather than signaling a hazardous state the safety interlocks are designed to protect against, so it’s not considered a typical lockout cause.
