Product Description

C7012E1112/U, C7012E1146/U, C7012E1187/U, and C7012G1019/U Flame Detectors is solid-state electronic devices for sensing the ultraviolet radiation emitted during combustion of most carbon-containing fuels such as natural gas, LP gas, and oil.Features:
All model• Solid-state electronic circuitry provides low power consumption and high reliability.• Solid-state models directly replace previous models with vacuum electron tube circuitry.• Detectors can be mounted horizontally, vertically or at any angle. The self-checking C7012E,F models require faceplate alignment and have integral locating reference points to assure proper shutter mechanism operation.• Ultraviolet radiation sensing tube and quartz viewing window are field replaceable.• Threaded conduit fitting and color-coded leadwires allow rapid electrical installation.• Two flame detectors can be wired in parallel to reduce nuisance shutdowns in difficult flame sighting applications.• A swivel mount is available to facilitate flame sighting.• Models are available with a -40°F (-40°C) rating.

7012A,C,G• Designed for use with Honeywell Flame Safeguard Controls using Honeywell Rectification (R7247A, R7289A, R7847A1082) and Ampli-Checkô Rectification (R7247B, R7847B1072) Flame Signal Amplifiers.C7012G• models available to meet BGC (British) and DIN (German) requirements. C7012E,F• Incorporate UV sensor tube checking feature; used with Honeywell Dynamic Self-Check (R7247C, R7847C) Flame Signal Amplifiers.• Oscillating shutter interrupts ultraviolet radiation reaching UV sensor between 60 and 120 times per minute (10 times per minute with R7747C dynamic self-check amplifiers) to provide the UV sensor tube checking function. Amplifier circuitry components are checked from the microprocessor in the BCS 7700 or 7800 SERIES Control.C7012A,E,G• Housing meets NEMA 4 enclosure standards (indoor, outdoor protection: rain-tight, dust-tight, hose-directed watertight).• Protective heat block built into mounting flange.• High pressure 50 psi (345 kPa) quartz viewing window, focusing lens, swivel mount and antivibration mounting accessories available.C7012C,F• Housing designed to be explosion-proof and Underwriters Laboratories Inc. listed for use in hazardous locations; Class I, groups C and D; and Class II, groups E, F, and G.• Viewing window rated for 100 psi (690 kPa).

Flame Signal

^a This minimum or greater signal should be obtained if the detector is correctly installed and positioned to properly sense flame.
This current or voltage must be obtained before completing the Checkout.
^b The circuitry tests ONLY the flame signal amplifier during burner operation and shuts down the burner if the amplifier fails.
^c Set selector switch on W136A Volt-ohmmeter to SPL (damped) position to read current.
^d Shutter operates ten cycles per minute.
^e Shutter operation of the C7012E,F causes fluctuations in the current reading. Read the average stable current or voltage, disre-
garding the peaks.
^f Shutter operates 12 cycles per minute (Series 1,2,3 Amplifiers). Series 4 or greater amplifiers, shutter operates when flame signal
of 1.5 Vdc is sensed. Readings will be constantly changing, usually between 0.9 to 2.3 Vdc on the S7800 Keyboard Display Mod-
ule.
^g Currently obsolete.
