Microcomputer Burner Control Systems

The BC7000 “Blue Chip” is an intelligent microcomputer-based integrated control system designedfor automatic fired commercial and industrial single burner applications. The BC7000 System not on-ly provides higher levels of protection, but also reaches far beyond the capability and scope of con-ventional flame safeguard “programmers” to reduce service, maintenance, downtime, and energycosts.

THE BC7000 BLUE CHIP MICRO-COMPUTER BURNER CONTROL SYSTEM:

Referred to as the Blue Chip because of its computer“chip” technology and its distinctive blue color, theBC7000 provides a return on investment (ROI/Payback): areal Blue Chip investment! The BC7000 Blue Chip Systemdelivers the following new and significant features in asingle integrated burner control system:

❑ Dynamic Self Check Logic—ProvidesMajor Safety Improvement

A major breakthrough in safety through advancedmicrocomputer technology has allowed the extensionof the original Honeywell Dynamic Self Check/MaxSafety concept (formerly restricted to the flame detec-tion circuit) to the basic program logic system. CalledDynamic Self Check Logic, it is a comprehensive familyof unique safety provisions that continuously monitorthe total system performance to provide the highestdegree of safety available.

Annunciation and Self-Diagnostics—CutService CostsControl and burner system startup, troubleshooting,and repair have never been easier, thanks to theBC7000 Microcomputer Burner Control System. in-tegral First-Out Annunciation and Self-Diagnostic func-tions reduce service costs and minimize the inconve-nience and cost associated with downtime. These im-portant new features are called “Plug-Instant” becausethey are a standard provision of the BC7000 System—no additional hardware need be purchased, installed, ormaintained.

Energy Saving Innovations—Reduce FuelConsumptionUnnecessary purge-related heat losses are minimizedby innovative BC7000 System program logic provisions.Microcomputer intelligence is employed to reduce fuelconsumption by optimizing the prepurge and ter-minating wasteful blower operation when the systemencounters an inoperative field interlock. This conditioncan cause conventional sequencers to permanentlystall in an unproductive purge.

Universal System Chassis—Minimizes In-ventory InvestmentNow, through the flexibility of microcomputertechnology, a single control chassis can be universallyapplied to perform any standard burner program. Solidstate program modules plug in to implement the re-quired burner sequence of operation, timings anddesired features. The universal BC7000 System chassisallows you to cover the full range of applications, sup-ports standardization, and minimizes inventoryinvestment.

SPECIFY THE BC7000 BLUE CHIPWhen ordering a new burner, packaged boiler, or control replacement, specify the new standard in burnerand flame safety control performance—the BC7000 “Blue Chip” Microcomputer Burner Control System.

❑ Enhanced safety improves plant protection

❑ Energy savings features provide on-going fuel savings and payback

❑ Plug-lnstant annunciation and diagnostics reduce service and downtime costs

❑ Universal system chassis supports standardization and minimizes inventory investment

BC7000 ‘BLUE CHIP’ MICROCOMPUTER BURNER CONTROL SYSTEMThe BC7000 provides flameout protection,automatic sequencing, dynamic self-check logic,plug-instant annunciation, self diagnostics andenergy conservation for commercial and in-dustrial single burners. Requires a PM720G, L, orM program module.Directly replaces R4150 and R4140 in most applications;mounts directly on the same Q520A subbase. Sequencesburner motor, firing rate motor (PM720G and L models on-ly), ignition, pilot valve, and main fuel valve(s). ExpandedSafe Start Check. Dynamic Self Check Logic. Plug-InstantAnnunciation. Self Diagnostics. Energy Conservation. Safe-ty shutdown on flame failure (lockout). Ten second pilotflame establishing period. Flame failure response time: 2-4seconds. Lockout switch timing: less than 1 second.

C7061A SOLID STATE DYNAMICSELF CHECK ULTRAVIOLET FLAME DETECTOR

Solid state electronic flame detector for use withEC7800 Burner Control family of Flame Safeguardcontrols and amplifier. Senses ultraviolet radiationgenerated by the combustion of gas, oil or other fuels.

Detector may be mounted horizontally or vertically orat any angle in between. The notch and arrow on thefaceplate must be lined up vertically for properoperation of the shutter.

Field replaceable viewing window and ultravioletsensing tube.

Threaded conduit fitting and color-coded leadwiresprovide rapid electrical hookup.

Two detectors can be connected in parallel to reducenuisance shutdowns.

Swivel mount is available as an accessory.

-40° F° (-40° C) rated ultraviolet sensing tube isavailable.

Designed for use with self-checking flame safeguardcontrols such as the R4075 C/D/E, R4138 C/D,R4140, BC7000, R7241, R4343B, R4348 andFSP5075 using the R7061 A plug in amplifier, or withEC7810, EC7820, EC7830, and EC7850 with R7861Aplug in amplifier.

Oscillating shutter interrupts the line of sight of thedetector about 120 times a minute with the R7061Aplug in amplifier to provide self checking. TheR7861A amplifier interrupts the line of sight of thedetector 12 times a minute. Any malfunction in theflame detection system results in a safety shutdown.The coil and shutter assembly is field replaceable.

Housing meets NEMA4 enclosure standards.

Protective heat block built into the mounting flange.

High pressure viewing window (rated for 50 psi(345kPa) magnifying lens, and anti-vibration mountare available accessories.
