Description
The self-check UV7SC scanner is used for continuous gas or oil flames. A mechanical shutter in the scanner closes every ten seconds, at which time the scanner’s internal circuit checks for a flame signal. If a signal is present, indicating a runaway scanner, the output signal is permanently interrupted, shutting down the flame safeguard system. 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. The detectors and signal processor automatically check every 10 seconds. It can be replaced without disturbing wiring. The UV7SC requires a cable assembly, P/N 59-504-010.
