Attention:

After having removed the hood, you might get in contact with the elec-trical connections in the terminal socket. Risk of fatal electric shocks!Therefore, you must interrupt the power supply before removing the hood.

Do not remove the jumper between terminals 1 and 2, which was mounted in the factory. It is required for the intended use of the automat-ic burner control system.

Description of the functions

Unlocking functionWhentheMPAislocked(state0),itcanbe unlocked by pressing the unlock key. In order to distinguish the function from possible EMC interfering impulses, the key must be kept depressed for at least 0.5s(max.5s).The same applies to the unlocking via 230Vandtotheunlockingviafieldbusmodules.

AccordingtoDINEN14459(annexJ),the number of possible unlocking pro-cesses is limited to 5 in 15 minutes, that means the automatic system denies furtherunlocking if theMPAhasbeenunlocked more than 5 times within a short time period. Only after a waiting timeduringwhichtheMPAisprovidedwith energy is it possible to unlock the MPAagain.

Thewaitingtimeis15minutesor3min-utes for each unlocking.

Extended unlockingThe described limitation to 5 unlocking operations in 15 minutes can be reset bymeansof "Extendedunlocking".Todo this, the unlock key must be pressed foratleast5s(max.10s)(after5sec-onds,thedisplaywillstartflashing).

The "Extended unlocking" is active inall operational states of theMPA, thatmeans that a safety shutdown with re-start of the MPA in operation can becarried out via the "Extended unlock-ing"alsointhepresenceofaflame.

The"Extendedunlocking"functionisnotpossibleviathe230Vunlockinginputorthefieldbusmodules!

Access levelWriteaccesstoMPAisdefinedondif-ferent access levels.Each parameter is assigned an access level. In order to modify a parameter, the MPA must be at the assigned orhigher level.If the access level is not sufficient tomodifyaparameter,theVisionBoxindi-cates it, or a message is output on the MPAdisplaypromptingtheusertoen-terthevalidpassword.Athigherlevels,theusersmustpressakey toconfirmthat they are "on site". The display isflashingfor30suntilakeyispressed;otherwise,theMPAremainsinthepre-vious level.

To change the access level, the cor-rect password must be entered via the displayorVisionBox→MPAsettings→Access level. The access level is au-tomatically reset after 5 hours or after power failure. Exception: If the auto-matic system performs a restart during these 5 hours, for example due to an error, these 5 hours for the current ac-cess level are counted again from the beginning.

NOTICEWe recommend resetting the accesslevel after having configured theauto-matic system.

AparametermaybemodifiedonthedisplayofMPAorviatheVisionBoxsoftwareonaPC.

In order to change a parameter, you need to set the access level assigned to the parameter.

The value must be within the variable limits; a value outside these limits is not possible. Depending on the access level, it is possible to change the variable upper and lower limits. The variable limits may only be changed by means of VisionBox,notontheMPAdisplay.Thevariable limits are restricted by means offixedlimits.Thesefixedlimitscannotbe changed.

To change parameters that cannot be changed during normal operation, it is necessarytochangetostate"Waitingforheatrequest".Most of the parameters are monitored inautomaticmode(switchontheboardon"Auto").TheMPAdetectschanges of the values and immediately changestofaultlock(error0x60).Anyvalue changes must be released in the parameterisation mode of a manual programrun(seealsoparametertable).

Parameter Designation Description Setting / Examples

P11 Field bus address configuration

SettingthebusslaveaddressofMPAIf an invalid address for the connect-edbusmoduleissetandtheMPAisin automaticmode, it restarts (error0x18).

If an invalid value for the connected busmoduleissetandtheMPAisinparameter mode, an error message is generated.

During operation and error messag-es, the current bus address may be seenbypressingthe←key.

Valuerange:OFF(nofieldbusavailable)1to254(e.g.Profibusadjustmentrangefrom1to126)

Note:Amodifiedvalueforthisparam-eter is not applied before a restart.

P12 Number of restart at-tempts or anti-oscilla-tion counter

Number of restart attempts of the MPA.Afterafailedlaststart,theMPAlocksinfaultswitch-off(state0"error").The anti-oscillation counter is reset when returning to operating state or whenunlockingtheMPA.

Valuerange:0-5attempts

P13 Number of restart attempts when flame is missing after the start-gas flame prov-ing period

The number of restart attempts after creating a flame (P12) can be lim-itedforthecasethattheflameisstillmissingafter thefirstsafety time forstart-up.The restart counter and the anti-oscillation counter are reset when changing to the operating state or af-ter unlocking.


Example:P12=5,P13=1Flame is still missing after the firstrestart→1.Restart attempt→Erroridle state control LDW→ 2. Restartattempt → Error idle state controlLDW → 3. Restart attempt → LDWOK after the third attempt, there is stillnoflame→Automaticsystemislocked although the number of re-startattempts(P12)hasnotyetbeenreached but the number of restart at-temptsaftermissingflamehasbeenreached.

P14 Number of restart at-tempts after a flame-out or missing flame after the second safety time for start-up

Thenumberofrestartattempts(P12)can be limited for the case that there isaflame lift-offor that theflame isstill missing after the safety time for start-up.The restart counter and the anti-oscillation counter are reset when changing to the operating state or af-ter unlocking.


Example:P12=5,P14=1Missing flame during operation →1.Restartattempt→Error idlestatecontrolLDW→2.Restartattempt→ErroridlestatecontrolLDW→3.Re-startattempt→AfterthethirdattemptLDWOK,thereisstillnoflame→Au-tomatic system is locked.

P15 Locking with open safety chain

If the safety chain is not closed, the MPAwaits in state 35 (safety chainopen). If the adjustable time (P20) haslapsed and the safety chain is still open, the system changes to fault lockdue toanerroror restarts (de-pending on the anti-oscillation coun-ter).

This setting is also valid if the safety chainisopenedafterstate4.

Setting:0:Restartattemptdependingontheanti-oscillation counter1: Immediate fault lock

P17 Temperature controller operating mode

This parameter can be used to con-figurethebehaviouroftheMPAandthe way it accepts the heat request viabusorviatheHWinputHeatre-quest/temperaturecontroller(X19).

Setting0:Only the hardware input Heat request is active, the bus signal Heat request is ignored.Note:Withthissetting,theairpurge(bussignal)cannothavepriorityoverheatrequest(P241Bit0=1),thiswillleadtoerrorconfiguration,seeerrorsfromthebasicsystemforerror0x18Setting 1: The bus signal Heat request is active, the burner can only be started if the HW signal is also active. If the busconnectionisinterrupted,theMPAisswitchedoff inaregularwayafteratolerancetimeof10s.Setting 2: The bus signal Heat request is active. If the bus connection is interrupted, the control system is switched to the HW signal after a tolerance time of10s.Setting3:The bus signal Heat request is rel-evant. If the bus connection is inter-rupted, theMPA isswitchedoff inaregular way after a tolerance time of 10s.Setting4:The bus signal Heat request is rel-evant. If the bus connection is inter-rupted, the MPA performs a safetyshutdown with fault lock after a toler-ancetimeof10s.ATTENTION: In contrast to Profibus, Modbus isnot equipped with a cyclic commu-nication. The MPA, however, waitsfor one Modbus request per minute, therefore an interrupted communica-tion cannot be detected immediately. If the request is missing, the bus module reports the automatic system thatthereisabusinterruptionandF9flashesonthedisplay.OnlyafterthistheparameterP17becomesactive.

DEZ ignition transformers

Technical description

The DUNGS DEZ are electronic high-performance ignition transformers with high-frequency oscillation technology.Compared with conventional induc-tive ignition transformers, the DEZ are much smaller and lighter.Designs for one or two ignition elec-trodesareavailableindifferentvoltageversions.

Application

Foroilandgasburners,ignitiontakesplace, depending on design, with one ignition electrode against the burner mass or with two ignition electrodes between the electrodes.

Electrical connectionConnection to the mains is made through pre-fabricated connection lines DEZ 1xx/2xx, which are available in differentlengths.

The ignition electrodes are connected viapre-fabricatedcarbonfibreignitionlines. The high line resistance of 10kOhm/meffectivelysuppressesEMC faults.

Theignitionlinesarefittedwithaninsulated6.5mmangleplugontheelectrode side.

Dimensions

AttentionThe operation of the DEZ ignition transformers produces very high volt-ages. The ignition transformers may only be put into operation if the ignition electrodes were built into the burner / burner chamber touch-proof and all live connections by means of the lines provided for this purpose were made touch-proof.

Thelengthoftheignitionline(s)mustnot exceed 1 m.

Connecting the protective earth is mandatory.Inthe"SEO"versionforsingle-elec-trode operation, the protective earth isconnectedtoterminal5oftheMPA41xx.
