The UV1A3/6 scanners come with 3 ft. and\n 6 ft. cables rated for Tray Cable - Exposed Run (TC-ER) and complies with the crush and impact\n requirements of the standard for metal clad cable, UL 1569. The UV1A-1-CEX is an ATEX rated\n version of the UV1A. The UV2 (36 inch) and UV2A6 (72 inch) are fitted with a 3/8” NPT female to\n 1/2” NPT male adapter fitted into the 1/2” threaded coupling of the UV1A3/6 respectively. The\n UV90-3/6/9 is available with 3 ft., 6 ft. and 9 ft. shielded flexible cables.\n The 3G-OTH-02859 Scanner is a 90° right angle ultraviolet flame scanner used in conjunction with the\n M-Series, M-Series II, MicroM, FlameWorx, MB-2 and D series controls as well as the Fireye®\n FLAME-MONITORTM, BurnerLogix and the Nexus System. It is available only with 72 inch\n (1830mm) unshielded lead wires.\n The 45UV3 Scanner has a rugged cast housing that mounts on a 3/4 inch pipe with sleeve and set-\n screw. The replaceable UV tube is mounted in a vertical position for greater sensitivity. Non self-\n checking.\n The UV90 Series Scanners are designed for front and lateral (90°) mounting which, in some applica-\n tions allow the scanners to obtain a clearer view of the flame. The UV90, with its exclusive snug-fit\n mounting block, eliminates the need for a threaded sight pipe.\n The UV tube is made of quartz and is filled with a gas that ionizes when struck by UV radiation from\n the flame. In the absence of UV radiation, the gas acts as an insulator between two electrodes which\n are mounted inside the tube. These electrodes are energized continuously by a high voltage. During\n combustion, UV radiation ionizes the gas, causing current pulses to flow between the electrodes.\n These current pulses result in a flame signal which is transmitted to the amplifier in the control,\n where it is processed to energize or hold in the flame relay.\n\n WARNING: When installing or replacing UV scanners, a minimum pilot turndown test on\n pilot ignited burners and a spark pickup test on all burners must be performed. Refer to bul-\n letins E-1101, C-4000, MC-5000 or BurnerLogix for recommended procedures.\n - All installations, service and troubleshooting of Fireye products must be performed by qual-\n ified technicians!\n\n\n\n\n 1\n\f \n\n\n\n\nAPPLICATION\n UV scanners are recommended for detecting flames from standard fuel gases, some waste gases and\n light oil fuels such as No. 2 oil. Flames from heavier oils can be detected with UV scanners but the\n unburned fuel shroud and/or atomization shroud can block passage of the UV from the flame zone to\n the UV tube, causing nuisance burner/boiler trips. Infrared detection is recommended for fuel oil\n heavier than No. 2, and some installations where waste gases are burned together with natural gas as\n a main flame.\n NOTE: Certain safety codes and regulations require the use of self-checking ultraviolet scanners.\n For information on self-checking UV scanners, refer to Bulletin SC-101.\n\nSPECIFICATIONS\n Operating Voltage: (S1-S2): 560 VAC @120V (230V) 50/60 Hz applied\n Operating Temperature Limits: Maximum: 200° F (94° C)\n Minimum: -40° F (-40° C)\n Humidity: 85% RH maximum non-condensing\n 1\n UV1A3: * /2\" NPT, 36\" (915mm) shielded leads\n 1\n UV1A6: * /2\" NPT, 72\" (1830mm) shielded leads\n 1\n 3G-OTH-02859: /2\" NPT, 72\" (1830mm) unshielded leads,\n UV1A-1-CEX: 1 NPT, 1/2\" NPT conduit cable entry\n 3\n UV2: * /8\" NPT, 36\" (915mm) shielded leads\n 3\n UV2A6: * /8\" NPT, 72\" (1830mm) shielded leads\n 45UV2-1020 1\" NPT mount 60 Hz, 72\" (1830mm) unshielded leads - OBSOLETE\n 3\n 45UV3-1050 /4\" Sleeve/setscrew mount, 72\" (1830mm) unshielded leads\n UV90-3 36\" (915mm) shielded leads\n UV90-6 72\" (1830mm) shielded leads\n UV90-9 108 \" (3660mm) shielded leads\n For scanner dimensions refer to Figures 2 and 4.\n Consult factory for custom lead lengths.\n * Comply with NEMA 4X\n\n\nIMPORTANT NOTE\n The information provided in this bulletin is directed to assist boiler and combustion service techni-\n cians who are experienced in the installation and operation of Fireye Flame Safety equipment. Per-\n sons not familiar with Fireye products should contact the nearest Fireye representative or other\n qualified service group.\n The UV1A, UV2, 3G-OTH-02859, UV1A-1-CEX, 45UV3 and UV90 as well as all other Fireye scanners, are\n designed to be used exclusively with the appropriate Fireye Flame safeguard and Burner Manage-\n ment controls. The application of these scanners to other than Fireye equipment should be reviewed\n for approval by Fireye.\n\n\nAPPLICATION REFERENCE\n UV1A, UV2, 3G-OTH-02859, 45UV3 and UV90 can be used only with the following FIREYE flame safe-\n guard controls.\n FIREYE MB-2 SERIES MicroM & D SERIES PFM FLAMEWORX NEXUS BURNERLOGIX\n FLAME-MONITOR M-SERIES II ADAPTOR KITS\n To be used with Use with MAUV1 All D-Series PFM2UV MBUV-300D NX3000 YB110UV\n EUV1 Amplifier 61-3359 MAUV1T using PFM3UV MBUV-310D NX3100 YB230UV\n Card UV Amplifier MEUV1 72DUV1 NX4000\n MEUV4 Amplifier NX4100\n\n\n\n2\n\f \n\n\n\n\n CAUTION: The UV1A, UV2, 3G-OTH-02859, 45UV3 and UV90 ultra-violet flame scanners and asso-\n ciated amplifier modules are non-self checking UV systems and should be applied only to\n burners that cycle often (e.g.: a minimum of once per 12 hours) in order for the safety check-\n ing circuit to be exercised. If component checking is required during burner operation for\n constantly fired burners, utilize the self-checking ultra-violet flame scanners (45UV5) with\n associated amplifier module (EUVS4), (MEUVS, (MBUVS) or YB110UVSC or the infrared\n flame scanner (48PT2) with associated Auto Check amplifier (E1R1, E1R2, E1R3, MEIR1,\n MEIR4, YB110IR).\n\nFIGURE 1.
