LC LB C - RP TDouble valve Dungs DMVDLEIt is a single body valve assembly includung two class Aelectric gas valves. One of them is slow opening type.The valve assembly can be coupled with leakage controlDungs mod. VPS504.To set gas flow rate use screw RP, under cover C. Clockwiserotation reduces flow rate, counter clock wise rotation increasesit.To set slow opening remove cover T, reverse upside down anduse it as a tool to rotate screw WR. Clockwise rotation reducesstart flow rate, counter clockwise rotation increase it.

Dungs valve leakage monitor device VPS504The VPS504 check the operation of the seal of the gas shut offvalves costituting the DMV-DLE. This check, carried out assoon as the boiler thermostat gives a start signal to the burner,creates, by means of the diaphragm pump inside it, a pressurein the test space of 20 mbar higher than the supply pressure.When wishing to monitor the test, install a pressure gaugeranged to that of the pressure supply, point Pa. If the test cycleis satisfactory after a few seconds the consent light LC(yellow) In comes on. In the opposite case the lockout light LB(red) comes on. To restart it is necessary to reset the applianceby pressing the lamp/button LB.

ADJUSTMENT

MVDLE gas valveTo adjust the gas flow rate loosen the screw VB and rotate the regulator RP asnecessary. Flow decreases with tightening and increases with unscrewing. Tightenscrew VB. For adjusting the speed of operation, remove the cap T, turn it overand fit on the pin VR with the appropriate spline placed on the upper part. Bytightening it the starting flow rate decreases. By slackening it the starting flowrate increases. N.B. The screw VSB must only be removed for replacement ofthe coil. Do not adjust the screw VR with a screwdriver.

MVD gas valveTo adjust the gas flow unscrew the plug T, slacken the lock nut and apply ascrewdriver to the adjusting screw VR. By turning in the clockwise direction theflow is reduced and by turning in the anticlockwise direction it is increased. Whenthis operation has been completed lock the lock nut and screw down the plug T.To replace the coil remove the plug T, withdraw the coil B and after replacing thecoil refit the plug T.

- During testing in the facory the gas butterfly valve, air damper and oilnozzle pressure at low flame and the servo-control cams set accordingly.

- To recalibrate the burner at the time of on-site testing, employ thefollowing procedure.

1. Light the gas burner and keep the servo-control in the ignition position byusing the AUTO-MAN on the servo-control switch (ignition position = 0°).

2. To regulate the ignition air flow move the servo-control cam AB (seefig.24) (to increase air flow increase servo- control position angle). Toregulate the ignition gas flow turn the adjustable screws V (see fig. 26) tochange the opening of the butterfly valve (see Fig.25). Turn clockwise toincrease the gas flow and anti-clockwise to reduce it.

3. Switch off the burner, put the AUTO-MAN servo-control switch in AUTOposition and start the burner again. If the setting is correct proceed to point4, on the contrary correct it again.

4. With the servo-control switch in MAN position turn the servocontrol up tohigh flame (servo-control position = 90°).IMPORTANT NOTICE: move the servocontrol by hand slowly, takingcare to combustion values in order to be sure not to let the burner functionwith insufficient air flow. Regulate the gas flow to the required figure byadjusting the pressure stabilizer or the regulator valve (see page 10). Toadjust the air flow rate slacken the screw RA and rotate the screw VRA(CW rotation increases air flow, while CCW rotation decreases it) until thedesired flow rate is obtained. (fig. 26).

5. Turn the burner down to low flame, to regulate the gas flow act on theadjustable screws V as described at point 2.

6. Should it be necessary to adjust burner capacity at low flame move theservocontrol cam BF accordingly (see Fig.24). The low-flame positionshould never coincide with the ignition position, so for this reason thecam has be calibrated at least 5° off the ignition position.

7. Put the AUTO-MAN servo-control switch in AUTO position and checkburner starting again, if gas or air flow need further adjustment proceedas described at point 2.

8 Light the oil burner. Should it be necessary to adjust the oil ignition flowmove the adjustable screws as shown in fig. 21.

9 With the servo-control switch in MAN position , turn the servocontrol upto high flame following the same precautioni described at point 4. Turnthe servocontrol switch to “AUTO” position and regulate the oil flow bymeans of “V” screws, see fig. 21.

10 Turn the burner down to low flame, check combustion, if necessaryregulate the oil flow by adjusting the screws “V” (see fig. 21).

N.B. On final adjustment, make sure the locking screw RA is fully tightened.

PART II: OPERATIONS MANUAL

OPERATIONS MANUAL

LIMITATIONS OF USETHE BURNER IS AN APPLIANCE DESIGNED AND CONSTRUCTED TO OPERATE ONLY AFTER BEINGCORRECTLY CONNECTED TO A HEAT GENERATOR (E.G. BOILER, HOT AIR GENERATOR, FURNACE,ETC.), ANY OTHER USE IS TO BE CONSIDERED IMPROPER AND THEREFORE DANGEROUS.

THE USER MUST GUARANTEE THE CORRECT FITTING OF THE APPLIANCE, ENTRUSTING THEINSTALLATION OF IT TO QUALIFIED PERSONNEL AND HAVING THE FIRST COMMISSIONING OF ITCARRIED OUT BY A SERVICE CENTRE AUTHORISED BY THE COMPANY MANUFACTURING THEBURNER. A FUNDAMENTAL FACTOR IN THIS RESPECT IS THE ELECTRICAL CONNECTION TO THEGENERATOR’S CONTROL AND SAFETY UNITS (CONTROL THERMOSTAT, SAFETY, ETC.) WHICHGUARANTEES CORRECT AND SAFE FUNCTIONING OF THE BURNER.

THEREFORE ANY OPERATION OF THE APPLIANCE MUST BE PREVENTED WHICH DEPARTS FROM THEINSTALLATION OPERATIONS OR WHICH HAPPENS AFTER TOTAL OR PARTIAL TAMPERING WITH THESE(E.G. DISCONNECTION, EVEN PARTIAL, OF THE ELECTRICAL LEADS, OPENING THE GENERATOR DOOR,DISMANTLING OF PART OF THE BURNER).

DO NOT EVER OPEN OR DISMANTLE ANY COMPONENT OF THE MACHINE.

OPERATE ONLY THE MAIN SWITCH (“ON-OFF” SEE FIG. 31), WHICH THROUGH ITS EASY ACCESSIBILITYAND RAPIDITY OF OPERATION ALSO FUNCTIONS AS AN EMERGENCY SWITCH, AND ON THE RE-SETBUTTON.

IN THE EVENT OF REPEATED LOCKOUTS, DO NOT PERSIST WITH THE RE-SET BUTTON AND CONTACTQUALIFIED PERSONNEL WHO WILL PROCEED TO ELIMINATE THE MALFUNCTION.

WARNING: DURING NORMAL OPERATION THE PARTS OF THE BURNER NEAREST TO THE GENERATOR(COUPLING FLANGE) CAN BECOME VERY HOT, AVOID TOUCHING THEM SO AS NOT TO GET BURNT.

OPERATION

- Select the fuel by turning the switch A on the burner control panel.N.B. where light oil is used make sure than the interceptor valves on the feed and return tubes are turned on.

- Check that the mechanism is not blocked (LED B lights up), if it is reactivate it by pressing the reset button C.- Check that the series of thermostats (or pressostats) gives the all clear for operating the burner.

Gas Operation- Check that the gas feed pressure is high enough (LED D will come on).- Start the checking cycle for the gas-tight monitor of the gas valves. When the check is completed the gas-tight monitor LED

will light up on the control panel. When the gas valve check is completed the burner start-up cycle begins.- At the beginning of the start-up cycle the servo control operates the air damper to maximum opening and the fan motor

starts and the pre-purge phase begins. During the pre-purge phase the complete opening of the air damper is signalled bythe lighting of the indicator light F on the front panel.

- At the end of the pre-purge the air damper is brought to the ignition position, the ignition transformer is energised (signalledby indicator light H on the panel) and, after 3 sec., the two gas valves EV1 and EV2 are energised (indicator lights I and Lon the mimic panel). 3 seconds after the opening of the gas valves the ignition transformer is de-energised and the light His extinguished.

- The burner is firing in low flame (indicator light G lit up); after 14 sec. 2-stage operation initiates and the burner is broughtautomatically into high flame, or remains in low flame according to the requirements of the plant. Operation in high or lowflame is signalled by the lighting up/extinguishing of the indicator light F on the mimic panel.

Light Oil operation- The ventilation motor comes on and the pre-ventilation phase begins. Since the pre-soak cycle must be carried out with

maximum air flow the monitor only switches on the servo-control once the damper is fully open which in turn signals the startof the pre-ventilation time period lasting 36 seconds.

- At the end of the pre-ventilation period the servo-control moves to the light oil ignition position, and as soon as is reaches thisposition the ignition transformer comes on (indicated by LED I on the display panel). Two seconds after the light oil valve opensthe ignition transformer is cut out of the circuit and LED I goes out.

it.A response to start-up given by the thermostat or pressostat “R”A-B start-up programmeB-C normal burner operationC regulation stop caused by “R”C-D programmer returns to start-up position A.During the regulation stop only terminals 11 and 12 are live and the damper,through the limit contact “Z” of its servo-motor is in the CLOSED position.The flame detector circuit F is activated (terminals 22 and 23 or 23/4) forthe detector test and the paracitic light test.Where the burners do not have dampers (or have an independent 00damper control mechanism) there must be a bridge between terminals 6and 8, otherwise the mechanism will not start up the burner.

For a burner to start up the following conditions must be met:- Mechanism not blocked/reset.- Damper closed. Limit contact switch Z must be in the CLOSED

position and allow current to flow between terminals 11 and 8.- Any contacts checking that the fuel valve (bv...) is closed, or other

contacts with similar functions, must be closed between terminal12 and the air pressostat LP.

- The contact for the air pressostat LP must be in the off position (LPtest) so as to feed terminal 4.

- The gas pressostat contacts GP and the safety thermostat andpressostat contacts W must also be closed.

Start-up programmeA Start-up(R closes the start-up control ring between terminals 4 and 5)The programmer starts up. At the same time the ventilator motor is fedthrough terminal 6 ( only for pre-ventilation) and, after t7, the ventilatormotor or the combustion gas exhaust fan is fed through terminal 7(pre-ventilation and post-ventilation).At the end of t16, the command opening the damper passes throughterminal 9; during the damper travel time the programmer does not movesince terminal 8, through which the programmer is fed, is dead. Only oncethe damper is fully open and the limit contact switch A has switched on,feeding terminal 8, does the programme proceed.

t1 Pre-ventilation time with damper fully open (nominal air flow).Shortly after the beginning of the pre-ventilation time, the airpressostat should switch off the current between terminals 4 and13; otherwise the apparatus would block (air pressure monitor).At the same time the terminal 14 should be live since currentfeeding the ignition transformer and the fuel valves passes throughthis circuit. During pre-ventilation time the flame detector circuit ischecked and in the event of an operational defect the monitorbrings about a block. At the end of the pre-ventilation time themonitor automatically moves the damper servo-motor, throughterminal 10, to the flame ignition position which is governed by theauxiliary contact “M”.During this period the programmer stops until terminal 8, is againactivated through contact “M”. After a few seconds the littleprogrammer motor is directly fed by the active part of the apparatus.After this point terminal 8 plays no further part in the burner ignitionprocess.

Mono-tube burnert3 Pre-ignition time up to the response from the fuel valve at

terminal 18.t2 Safety time (potential flame start-up) At the end of the safety time

a flame signal should appear at terminal 22 of the amplifier and thatsignal should stay on until a regulation stop; if this does not happenthe mechanism will block.

LANDIS & GYR LFL 1,322Automatic programme in the event of interruption and indication ofposition when interrupted In principle, in the event of any kind ofinterruption, the flow of fuel is immediately interrupted. At the sametime the programmer stops and this indicates the position at the time of theinterruption.A symbol on the indicator disc shows each time the type of stoppage:

No start-up (for example fault in the CLOSED signal for thelimit contact “Z” terminal 8 or some other contact betweenthe terminals 12 and 4 or 4 and 5 is not closed).Start-up suspended because of a fault in the OPEN signalfor the limit contact “A” at terminal 8.Block due to absence of air pressure signal.From this moment onwards any absence of air pressurewill cause a block.Block due to malfunction of the flame detector circuit.Start-up interrupted because there is a fault in theMINIMUM signal for the auxiliary contact of the damperservo motor at terminal 8.Block due to absence of flame signal at the end of the (1st)safety period.From this moment onwards any absence of a flamesignal will cause a block.Block due to absence of flame signal at the end of the 2ndsafety period (flame signal of main burner).Block due to absence of flame signal or air pressure duringoperation.

Block at the end of the start-up programme due to parasitic light or faultyflame signal (eg. UV detector is exhausted).Where a block stoppage occurs at any moment between switch on andpre-ignition without registering any symbol, the cause is normally anunscheduled flame signal.

a-b Start-up programmeb-b’ For time variants: move the programmer on to the automatic

stop after the burner starts up (b’ = position of the programmerduring normal burner operation).

b(b’)-a Post-ventilation programme after a regulation stop. At thestart-up position “a” the programmer stops automatically.

‘ During safety time for mono-tube burners‘’ During safety time for twin-tube burners

The apparatus can be reset immediately after a block. After resetting (andafter the elimination of any problem causing the stoppage or after a powerfailure) the programmer returns to its start-up position. In this event onlythe terminals 7, 9. 10 and 11 are live in accordance with the monitoringprogramme. Only after this will the monitor programme a fresh start-up.

OperationThe wiring system and also the control system of the programmer “P” havealready been given in this manual (page--). The response signals requiredfor the active parts and the flame monitor circuit are shown by a broken line.In the absence of these response signals the mechanism interrupts thestart-up programme; the exact time of the interruption can be identifiedfrom the visual indicator and will cause a block if the safety code requires

t9 2nd safety time At the end of the second safety time the principalburner should be lit by the pilot. At the end of this period terminal17 is dead and therefore the pilot burner will be out.

t5 Interval At the end of t5 terminal 20 is live. At the same time themonitor outlets from 9 and 11 and at terminal 8 into the active partthe apparatus are galvanically separated so as to protect theapparatus itself from recovery voltage through the capacity regulatorcircuit.When the capacity regulator LR at terminal 20 gives the all clear,the start-up programme for the apparatus comes to an end. Withtime variants the programmer stops either immediately or at theend of a set time, without effecting the position of the contacts.

B-C Burner operation (production of heat)While the burner is working the capacity regulator controls the damperaccording to the demand for heat, by means of the positioning at nominalload of the auxiliary contact “V” of the damper servocontrol.

C Regulation stop for operation of “R”When there is a regulation stop the fuel valves immediately close. At thesame time the programmer starts to programme:t6 Post-ventilation time (post-ventilation with the ventilator “G” at

terminal 7). Shortly after beginning of the post-ventilation timeterminal 10 becomes live and moves the damper to the “MIN”position. The full closure of the damper only happens towards theend of the post-ventilation time and is prompted by an automaticsignal from terminal 11

D-A End of automatic programmeAt the end of t6, at the point where the programmer and the automaticcontacts have reverted to the starter position, the detector test restarts.During an operational stop even an unscheduled flame signal lasting a fewseconds can cause a block so during this period an NTC in the circuit actsas retarder. This means that brief unscheduled influences cannot causea block.(**) Times t3, t2 and t4 only apply to safety devices in the series 01.

OperationThe gear assembly sucks in the oil through the filter andtransfers it under pressure to the valve. When the springreaches the calibrated figure the oil pressure forces the pistonhead back allowing the oil to pass along the line to the nozzle.Any oil surplus to the flow at the nozzle is unloaded through thevalve to the return tube and back to the tank (twin-pipeinstallation) or to the suction chamber (single-pipe installation).When the motor stops there is a drop in the pressure and thisallows the spring to give the piston a sharp push forwards, thusclosing the aperture to the nozzle tube (cut-off function). Eachstroke of the piston automatically drives out the air - twin- tubesystem - and accelerates the movement of the piston and thusensures a quicker cut-off.
