System compatibility

UV90-9 belongs to Fireye UV90 flame scanner family. Compatible with Fireye YB110UV, ZB110UV non-self-check UV amplifier burner chassis. Matches YP series programmer modules, BLV512 / BLL510 display units. Widely used for gas and light oil boiler and furnace burners. Widely used for combustion safety system spare replacement.

Function

UV90-9 is non self-check ultraviolet flame scanner manufactured by Fireye. It captures ultraviolet flicker radiation from combustion flame and converts flame signal and transmits to burner control chassis. This model has no internal sensor self-test circuit. When flame extinguishes, scanner stops sending flame signal, burner chassis triggers safety lockout and cuts fuel supply to eliminate explosion hazard. It supports front or 90° lateral installation for difficult sighting positions. The 108-inch pre-wired shielded cable simplifies field wiring work. Widely deployed for industrial boiler and furnace burner flame monitoring and spare replacement.

Installation

Follow lockout/tagout safety procedure before installation. Install UV90-9 with supplied snug-fit mounting block on burner sight port, align optical window toward flame. Keep quartz window clean. Route integrated shielded cable to non-self-check UV burner chassis, strictly follow Fireye wiring schematic. Power on and test flame signal strength during burner commissioning.
