AC-Amplitude is defined as a measurement of the intensity of the flicker or pulsation of
the flame. It is one of the Measured-Values
Uvisor™ Integrated SafeFlame Scanner
Terminal board for the SF910i
Atmosphere explosive
Burner Management System
Channel is a connection to a Flame Scanner. SF910i includes two channels. Each
channel can be independently connected and operated by the SF910i
SF910i is in Configuration-Mode when it is enabled to modify configuration functions
Used as synonymous of BMS
Flame Scanner made of three parts namely a scanner head, a separate electronic unit,
and a cable connecting the two
Drop-Out occurs when a Measured-Value goes below the Drop-Out value
Direct View, see LOS
Electro Static Discharge
Safe-relay is an ON/OFF switch that is energized when no faults are present, and
de-energized when faults are detected
Flame Failure Response Time, the time period from flame-off (absence of a flame) to
the flame-relay off (contact open)
First-Time Power up is a mode of operation that the SF910i automatically enters when
it is factory new or when a complete reset of the configuration performed
Software tool for configuration and monitoring
Flame Scanner is a unit that detects changes in a light source
Flame-Logic is the program code that determines when a flame is considered ON
(Flame-On) or OFF (Flame-Off). This Flame-Logic can be customized using SF910i
menus
