LED STATUS INDICATORS; “Ring of Light”:
The iScan®3 Flame Scanner provides visual feedback on flame conditions and system health with a bright
LED display.
Figure 2: LED Status indicator
The “Ring of Light” communicates the scanner’s operating modes, including FLAME SIGNAL STRENGTH,
GAIN LEVEL (the amount of signal amplification), and WARNINGS/FAULTS. This ring aids with “sighting”
the flame, or in other words: proper aiming of the scanner. This must be done carefully to ensure a good
flame signal is present over various operating conditions. With the “Ring of Light,” the operator can quickly
recognize marginal conditions (such as low flame strength and/or high gain).
