IMPORTANT NOTE

The information provided in this bulletin is directed to competent boiler and combustion service

technicians who are experienced in the installation and operation of Fireye Flame Safety equipment.

Persons not familiar with Fireye products should contact the nearest Fireye representative or other

qualified service group.

The 45UV5 scanners as well as all other Fireye scanners, are designed to be used exclusively with

the appropriate Fireye Flame Safeguard and Burner Management controls. The application of these

scanners to other than Fireye equipment should be reviewed for approval by Fireye.

APPLICATION

Fireye 45UV5 self-checking scanners are used to detect ultraviolet emissions from fossil fuel flames

such as natural gas, coke oven gas, propane, methane, butane, kerosene, light petroleum distillates

and diesel fuels.

These 45UV5 models are used only with the Flame-Monitor, BurnerLogix, D-Series, FlameWorx,

MicroM and some P-Series Fireye control models to provide flame safeguard and monitoring sys-

tems for supervised manual, semi-automatic and fully automatic single burner boilers, process ovens

and heaters.

PRINCIPLES OF OPERATION

The 45UV5 scanners use a UV-eye detector. This detector is a sealed, gas filled, UV-sensitive tube

containing two electrodes connected to a source of AC voltage. When UV radiation of sufficient

energy falls upon the electrodes, electrons are released and the inter-electrode gas becomes conduc-

tive, resulting in an electric current flow from one electrode to the other. The current flow starts and

ends abruptly and is known as an “avalanche.”

A very intense source of UV radiation will produce several hundred avalanches or pulses per second.

With less radiation there will be fewer pulses per second. Upon total disappearance of flame, the

detector output ceases. Thus, the presence or absence of pulses is an indication of the presence or

£ absence of flame; the frequency of the pulses is a measure of flame intensity. Pulses generated by the scanner are transmitted to a compatible Fireye control via scanner wiring. FEATURES The components are contained in a cast aluminum housing sealed with an oil-resistant gasket. The quartz lens is a planoconvex design, resulting in increased sensitivity.

® Housing Material: Cast aluminum Weight: 7 lbs. (3.2 kg) Housing Dimensions: See Fig. 1 Purge Air: 4 SCFM (113L/min) at 3/8 inch threaded housing inlet or 4 SCFM at 1 inch wye fitting in scanner sight pipe. Temperatures near the upper limit of the scanner operating range and/or use with dirty duels may require up to 15 SCFM (425 L/min.). Optical Range: 2200 to 2600 angstroms. No response to infrared radiation or visible light. Optical Field of View: 1 inch per foot (25.

If combustion air enters the furnace with a rotational movement of sufficient velocity to deflect pilot flame in direction of rotation, position the scanner 0 to 30 degrees downstream of the pilot burner and close to the periphery of the throat where the ultraviolet radiation is at a maximum. (See Figures 2 and 3).

® Under normal temperature conditions, with clean burning fuels and moderate ambient temperature conditions, purge air flow of approximately 4 SCFM (113 L/min) is generally adequate. A 0.1 psig positive pressure difference between the atmosphere and boiler pressure measured at right angle to the purge air flow, should result in a purge air flow of 4 SCFM.

£ • • Avoid wire loops and poor groundings. Keep high voltage ignition wires well away from scanner wires. The 45UV5 self-check scanner has four 6 foot (1800mm) leads: 45UV5-1005 & 1105: Two black leads which power the shutter from the associated control and two red leads which drive the UV tube and carry the flame signal to the control amplifier.

Over 25 to 300 feet maximum: — Use #18 AWG or heavier, 600V, 75C rated wire for the two black leads (shutter). — Extended Scanner Wiring. For extended scanner wiring up to 1500 feet, and for shorter lengths to reduce signal loss, use a shielded wire (Belden 8254-RG62U) coaxial cable, or equal for each red wire of the 45UV5.

£ SWIVEL MOUNT The scanner swivel mount Part No. 60-1664-4 (BSP) 60-1664-3 (NPT) is used to adjust the scanner sighting angle after the scanner has been installed. The swivel mount is used as indicated the figures in this document. Orifices The Orifice restricts the field of view (target area), reduces air flow, maintains air flow, maintain air block, and increases discrimination between flame and background radiation.

® 2. 3. The scanner and sight pipe must be kept clean to prevent overheating and assure optical qualities. When replacing or cleaning the UV tube, note the position of the tube pins. They are mounted on a rectangular base so that the tube can only be inserted into the socket with the electrodes broadside to the shutter window.
