Weishaupt oil burners WL30 and WL40Standard version and LN1/2002 CA

The new worldof combustion technologyWeishaupt has opened a new chapterin digital burner management.The new rating capacity of thelegendary W series burners (WL30 /WL40: from 205 to 1,950 MBTU/h)uses the latest microprocessortechnology for setting, control andmonitoring of all burner functions. Theresult is a new series of burners, whichoffers not only improved comfort andprecision, but also value for money.Furthermore, the new burners are easyto commission, service and are quieterin their operation than other burnerswith a comparable rating.The newworld ofcombustiontechnology2

The latest developments in burner technology:More precision with intelligent electronicsStepping motorsCompact designLooking beneath the cover of the typesWL30 and WL40 reveals Weishaupt’susual logical layout of components.The horizontally fitted fan design hasalready proven itself. The most importantnew components are the newcombustion manager, which replaces theburner control previously used and thenew stepping motor, which regulates theair damper setting in steps of only a tenthof a degree, making it more accuratethan ever before.A new chapter in the history ofsuccessThis new construction principle of theWL30 and WL40 will be used for allsmaller types of compact burners in theWeishaupt W range. The result of thisdevelopment will be a range of burnersfrom 55 to 1,950 MBTU/h with identicaltechnology and maximum use of commoncomponents.Burner WL30 and WL40 version LN(LowNO x )An outstanding detail of the burnersWL30 and WL40 version LN is a newLowNO x , mixing head, which ensuresextremely low NO x emissions.Burner flangeIgnition unitIndicating boltSetting screwfor diffuserSolenoid valvenozzle assemblyCombustion managerwith connection plugsBurner motorOil pumpwith solenoid valveCapacitor for motorCoverVersion LN (LowNO x )4Standard version

Digital burner management:More comfort – less timeThe Computer as a friendAt the heart of the new burnertechnology lies the Weishauptcombustion manager. It’s efficientmicroprocessor controls and monitors allburner functions. The burner display withits simple operating panel displays allfunction sequences for burnercommissioning. All calculated values canbe displayed and, once the cover isremoved, all set values for burneroperation can be programmed with fourkeys.Unmistakable plug connectionCoded plug connections ensure thecorrect electrical connection of allcomponents.New stepping motorThe air damper stepping motor providesseparate air damper settings for burnerstart and burner operation.Report and diagnostic displayDuring burner operation the operatingmode (stage 1 or 2) and operations ofthe stepping motor are indicated on thedisplay.If a burner lockout occurs the display notonly shows the error message, but alsoan error code. This allows immediaterecognition and rectification of the causeof lockout.Keywords – Building ManagementSystemThe Weishaupt combustion manager isfitted with a serial bus connection. Toenable communication with othersystems an interface has been provided.A self-dialling modem can be interfaced,which can report the burner lockout andits cause to a designated telephone orfax connection (e.g. the heatingspecialist).Connections to other components (e.g.controller) or to the DDC installation canbe made via the same interface.The Weishaupt combustion managerBurner displayAir stepping motorData BUSCombustion managerIgnition unit/Ignition transformerFlame sensorBurner motorPBoilercontrolPStage 2Oil pumpSafetyvalveSolenoidvalve 1Solenoid valve 2Digital burner management on WL406

The most important features andfunctions of the Weishauptcombustion manager● Identical construction for oil andgas firing● Automatic recognition for gas or oilburner operation● Easy operation via a key on thedisplay panel● LCD display with the followingdisplays–Operating mode with ratingssetting–Information mode- Burner operating time(total, stage 2)- Number of burner starts-Measured fuel consumption-Unit number-Software version- Date of manufacture– Service mode-Burner setting values for start,operation and start of stage 2-Display of last 6 errormessages– Parameter mode-Air damper setting at burnershutdown-Post purge time-BUS address– Error message display● Operation of stepping motor● Multifunctional BUS connection to– PC for presentation of theoperational sequence andsetting of function parameters– Remote monitoring anddiagnosis via self-diallingmodem– Interfacing with othercomponents of heating plant(i.e. controller or DDC unit)Burner display with all operating keys (WL40 oil burner, burner cover removed)With burner cover in place the information key remains available to the operator7

A principle for the future:Excellent value for moneyOne concept – two convincingsolutionsA new construction concept was realizedwith this new W30 and W40 series ofWeishaupt burners. Both gas and oilburners are of identical basic design andare fitted with the latest microprocessortechnology. The result is easierinstallation, disposition, operation,setting and service, and spare partssupply.Saves money, saves time, savesenergySynergy effect during construction andfinishing, the use of economicalelectronic control and regulatortechnology and proven Weishauptcombustion technology ensure asolution, which is convincing not onlyfrom a technical point of view, but alsofrom an economical point of view.The new WL30 has a ratings range up to1,130 MBTU/h, the WL40 up to 1,950MBTU/h. In the past a Weishaupt burnerof this ratings class would have costconsiderably more. Due to its compactconstruction, the burner’s electricalconsumption has also been reduced.Only one service engineer is needed forinstallation. Commissioning simplymeans inputting the required values viathe keys on the burner display. Nocomputer or programming knowledge isrequired to carry out this work.8Compact form, classic design. The burner display is a ‘give-away’ of the new technology.

d2Installation, setting and service:Easier, quicker, more exact than ever beforeService position 1: Burner hinged open viahinged flangeTime is moneyIt has never been so easy to install andcommission a burner of this rating.One person can carry out mounting tothe boiler. Commissioning simply meansinputting the required values via the keyson the burner display. That’s it.Service position 2: Fan wheel, nozzleassembly and diffuser are fully accessibleOptimum accessibilityOptimum accessibility becomesapparent the moment the cover isremoved. All components are laid outclearly, electrical connection isunmistakable. This state of the arttechnology is typical of Weishauptproducts.These components are also easilyaccessible for servicing. The wholeburner can be hinged open, including theEasy access to the mixing headvalve assembly and diffuser from theflame tube. Furthermore, the nozzleassembly and diffuser can be removedtotally by opening the bayonet fitting.The housing cover with motor block andcombustion manager can be removedand placed into a service position forservicing the fan. Every service engineerbenefits from this “accommodating”construction.Burner dimensions – WL30 and WL40α °h 2h1d4d3b2l5b1l1l4R 2b3l7d1R1l3l2l6Dimensions in inchesl1 l2 l3 l4 l5 l6 l7 b1 b2 b3 h1 h2 d1 d2 d3 d4 R1 R2 α°WL30 18.9 10.6➀ 1.6 1.2 2.4 23.6 18.1 16.5 8.9 3.9 18.1 13.5 5.0 M8 6.7 - 7.7 5.1 6.2 19.3 45°WL40 22.7 9.3 1.6 1.2 2.8 24.2 18.9 17.7 9.6 4.3 18.9 14.2 5.9 M10 7.3 - 7.9 6.3 7.3 22.4 45°➀ Dimension for WL30Z-C.
