Protection Controls Flame Safeguard Protectofier Model 6642VB with breaker - lockout switch is required for automatic lighted installations. This is used as a single and/or a multi-burner combustion safeguard. System "latches out" after failure to light within ignition trial time and cannot attempt restart until switch is manually reset.
Standard ignition trial time is 15 seconds. Also available in 10 second and 5 second trial time.
The basic operation of the Protection Controls Protectofier model is that it monitors one or more burners and responds to the presence or absence of flame via the rectification principle. When using a flame rod, the flame itself serves as a switch to pen or close a DC circuit to the Protection Controls Flame Pak. Similarly, when using a Protection Controls P-C II Scanner, a DC signal source is created by the ultra-violet sensitive tube only when the flame is scanned. With either sensing system, if the signal from flame to Flame Pak is interrupted (response time, 4 seconds or less), the circuit to the safety shut-off valve is broken, which automatically shuts down the complete system (and can also energize circuit to alarm). The Protection Controls Telefier light instantly indicates faulty burner in a multi-burner system.
