Honeywell Eclipse 90 Quick Start Manual

Introduction
This sensor features a high sensitivity ultraviolet (UV)
tube for monitoring gas or oil flames that cycle on and off
frequently. It is protected against reverse connection. The
Eclipse flame safeguard checks for a short-circuited, or
"runaway" scanner at the beginning and end of each
flame cycle. The scanner is UL listed for USA and
Canada, and is FM approved. This product is also in
conformance with the "CE Mark" directives when used
with the model VF56 Veri-Flame CE as listed in Instruction
Manual 818-2. It comes with a 10 ft (305 cm) lead. The 90°
UV Scanner operates with 5600 and VF56 series Veri-
Flames, the 6000 Series Multi-Flame and 6500 Series Bi-
Flame controllers, or series 7000 Peek-A-Flame.
The UV tube is made of quartz and is filled with a gas that
surrounds two electrodes. These electrodes
energized continuously by a high voltage. The gas acts as
an insulator in the absence of UV radiation. Combustion
produces UV radiation to ionize the gas and causes
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 and hold in the flame relay.
