1. The interlock of the burner cooling water standby valve system is ineffective in manual mode for the inlet and outlet valves of the burner cooling water during shutdown. How should this sentence be understood?
In manual mode for the inlet and outlet valves of the burner cooling water for parking, the interlock of the burner cooling water standby valve system fails.
If the burner cooling water standby valve system is in interlock mode, the manual mode for the burner cooling water inlet and outlet valves during shutdown is invalid. It can be understood that way, right?
In normal manual mode, interlocking is ineffective. In automatic mode, chaining takes effect. In automatic mode, if a certain situation occurs that can trigger a chain reaction, it is possible to switch to manual mode, thereby breaking off this chain reaction and preventing a widespread shutdown of the system.
In manual mode, the burner cooling water inlet and outlet valves are closed, and the backup valve interlock system for burner cooling water does not function
That is, the interlock has failed; to determine this, one needs to consider whether there is a poor connection or disconnection in the circuit connection, and whether there are issues with the configuration.
When the burner cooling water inlet and outlet valves are set to manual mode, the interlock of the cooling water backup valve system becomes ineffective.
It means that interlocking fails in manual mode; in previous designs, a manual/automatic switch was usually provided, and the interlocking had to be bypassed when operating manually.
Well, I’ve learned it now; so that’s how to understand it.
