Fireye UV7A4 UV Scanner 0.3mA Non Self-Checking Flame Scanners Are Used With MBSERIES Multi-Burner Control

Product Description

Data sheet
The non self-check UV7A4, UV7R4 and self-check UV7SC scanners are used with the MBSERIES Multi-Burner control, the SBSERIES single
burner control and the flame sensing modules, MBPF-100S and MB-600PF.
The UV7R4 Scanner is a 90° right angle ultraviolet flame scanner. This sensor features high sensitivity ultraviolet (UV) for
monitoring gas or oil flames which cycle on and off frequently. The Fireye flame safeguard checks for a short-circuited, or
"runaway" scanner at the beginning and end of each flame cycle. The scanner is UL listed and FM approved. It comes with 72 inch
(1830mm) unshielded lead wires and is safeguarded against reverse connection.

 

 

DESCRIPTION:

The non self-check UV7A4, UV7R4 and self-check UV7SC scanners are used with the MBSERIES Multi-Burner control, the SBSERIES single
burner control and the flame sensing modules, MBPF-100S and MB-600PF. The UV7A4 scanner features high sensitivity ultraviolet (UV)
for monitoring gas or oil flames which cycle on and off frequently. The Fireye flame safeguard checks for a short-circuited, or
"runaway" scanner at the beginning and end of each flame cycle. The scanner is UL listed and FM approved. It comes with a 122 cm
(4 ft.) shielded flexible cable and a 1/2" F.N.P.T. insulated nylon coupling and is ideal for high temperature applications. The
UV7R4 Scanner is a 90° right angle ultraviolet flame scanner. This sensor features high sensitivity ultraviolet (UV) for
monitoring gas or oil flames which cycle on and off frequently. The Fireye flame safeguard checks for a short-circuited, or
"runaway" scanner at the beginning and end of each flame cycle. The scanner is UL listed and FM approved. It comes with 72 inch
(1830mm) unshielded lead wires and is safeguarded against reverse connection. 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 electro-magnetically driven photo shutter. The detectors and signal processor automatically
check every 10 seconds. It can be replaced without disturbing wiring. The UV7SC requires cable assembly, P/N 59-504-010. The UV
tube is made of quartz and is filled with a gas that ionizes when struck by UV radiation from the flame. In the absence of UV
radiation, the gas acts as an insulator between two electrodes which are mounted inside the tube. These electrodes are energized
continuously by a high voltage. During combustion, UV radiation ionizes the gas, causing current pulses to flow between the
electrodes. These current pulses result in a flame signal which is transmitted to the amplifier in the control, where it is
processed to energize or hold in the flame relay.

APPLICATION

UV scanners are recommended for detecting flames from standard fuel gases, some waste gases and light oil fuels such as No. 2 oil.
Flames from heavier oils can be detected with UV scanners but the unburned fuel shroud and/or atomization shroud can block passage
of the UV from the flame zone to the UV tube, causing nuisance burner/boiler trips. Infrared detection is recommended for fuel oil
heavier than No. 2, and some installations where waste gases are burned together with natural gas as a main flame. NOTE: Certain
safety codes and regulations require the use of self-checking ultraviolet scanners.
