APPLICATION TECHNOLOGY FEATURESCOMMISSIONING AND SERVICE/MAINTENANCE1. Flame Monitoring1. Important RemarksThe flame monitoring can be effected with the followingflame detectors:- With ionization electrodes in power grids with earthedneutral conductor, utilizable with gas burners (interferenceeffects of the ignition spark cannot influence the formationof the flame signal).- With infrared flicker detector type IRD 1020 for all typesof burners.- Before commissioning, the wiring has to be accuratelychecked. Faulty wiring can damage the unit and endangerthe safety of the installation.- The mains fuse has to be selected so that the limit valuesindicated under "Technical Specifications" are under nocircumstances exceeded. Non-compliance with thisregulation can have very serious consequences for thecontrol unit and for the installation in the case of a shortcircuit.- For safety reasons, at least one control shut-down per 24hours must be assured.- The control unit must be plugged-in or -out only when themains supply has been disconnected.- Automatic burner safety controls are safety devices andmust not be opened.2. Burner Control- The automatic burner controls MMI only operate, when aload is connected to terminal 5. If the fuel valve is interruptedby an external contact during the pre-purging phase, aresistance of max. 22 kΩ, 4 Watt has to be applied between the terminals 5 and 8.- Functional test of the air pressure monitor before thestartup and monitoring of the air pressure during the prepurging time, as well as in the operating condition of theburner. For normal applications a working contact with apower rating of 4 A / 230 V is sufficient.- In the case of the automatic control MMI 810, contacts canbe installed between the terminals 1 and 9 (e.g., valve limitposition contacts). These are checked for their correctclosing position when the unit is started up. The connection1 - 9 has to be closed during the starting phase of theautomatic control.- No fuel valve must be connected to terminal 6.2. Functional CheckDuring commissioning and after an overhaul of the burner,the following checks have to be carried out:a) Starting test with closed manual valve and bridged gasmonitor contact:-The device must go into a fault condition after the safetyperiod has elapsed.b) Close the manual valve in operating position with the gasmonitor contact bridged.-The device must go into a fault condition after a flamefailure.c) Air pressure monitor contact interrupted:-Device goes into a fault condition.d) Bridge air pressure monitor contact before starting:-Device must not start.3. SafetyWith respect to design and programme sequence, the gasburner automatic safety controls of the MMI type rangecomply with the currently applicable European standardsand regulations.3. Trouble ShootingBurner does not go into operation, programme indicationremains:- Electrical connection defective.- Thermostat or gas monitor "OFF".4. Mounting and Electrical InstallationOn the base:- 3 earth conductor terminals with additional strap for theearthing of the burner.- 3 neutral conductor terminals with an internal, fixedconnection to the neutral conductor input, terminal 8.- 2 individual slide-in plates and 2 fixed knock-out apertureswith thread PG 11, as well as 2 knock-out apertures frombelow, make the wiring of the base more easy.Burner does not go into operation, programme indicationrotates continuously:- Air pressure monitor defective, respectively, not in startingposition. (Working contact must be open).The automatic control switches to fault condition shortlyafter the start of the pre-purge time (line within the bluezone):- Air pressure monitor contact does not close.- No load on terminal 5.- Flame signal.General:- Mounting position as required, insulation standard IP 44(splash-proof). The automatic control and sensor should,however, not be exposed to excessive vibration.- During mounting and installation, the applicable regulations for installation have to be observed.Automatic control switches to fault condition during theoperating position (red, resp. green zone):- Flame lift-off- Air pressure monitor contact opens- Flame signal too weak.2MMI 812Automatic control switches to fault condition during the prepurging (blue zone):- No flame formation (ignition missing, valve does not open,etc.)- No flame signal or too weak flame signal (flame does notadhere, poor insulation of the flame detector, burner notproperly connected to the earth conductor).
