Introduction
The self-check UV Scanner is used for continuous gas or
oil flames. A mechanical shutter in the scanner closes
briefly every ten seconds, at which time the scanner's
internal circuit checks for a flame signal. If a signal is
present, indicating a failed sensor, the output signal to the
flame safeguard is stopped and the system shuts down.
The scanner features a high quality fused silica quartz
lens, machined alloy housing with seals and a long life
push-pull electromagnetically driven photo shutter. This
scanner operates with the series 5600 and VF56 series
Veri-Flames, the series 6000 Multi-Flame, Series 6500 Bi-
Flame controllers, and series 7000 Peek-A-Flame.
Eclipse Self-Check
Factory Mutual (FM) recommends these scanners be
used when any fired equipment is operated continuously
(more than 24 hours without shutdown).
