MICROFLA T SERIES TYPES CM.. F SM.. F MM.. F TM.. F AUTOMATIC CONTROL SYSTEMS FOR Application GAS BURNERS AND GAS BURNING This range of electronic gas burner control systems has APPLIANCES WITH OR WITHOUT FAN been specifically designed for atn:iospheric burners for intermittent opE:ration (systems for non-permanent AND WITH BUILT-IN ANTI-EMISSIONS operation), with or without fan in the combustion circuit. FILTER Ali these.controls are provided with non-volatile lockout, i.e. a restart from the safety shutdown condition can only be accomplished by a manual reset of the system. The automatic burner control units of this series are suîtable for: -combi boilers; -heating boilers; -warm air generators; -radiant heaters; -water heaters. Thanks to their design and variety of models, they can also be used for the automation of ovens, cookers and in gas firing installations with atmospheric burner in general. Features Table 1 shows the main features of this series. Other important features are: - EC certification (CE Reg. N ° 63AQ0625) in accordance with Gas Appliance Directives 90/396 and 93/68; - in accordance with EN 298 (European standard for automatic gas burner control systems and flame detectors); - completely solid and high efficient inbuilt ignition device with built-in E.M. filter; - possibility of mounting a resistor (0 + 220 ohm) in series to the valve output. in case the valves operate with direct current obtained through the rectification of the supply alternate current by means of one or more diodes; - possibility of mounting a resistor (0 + 470 Kohm) in series to the lockout signal output, to avoid possible damages to the control in case the connections of the reset button and the connections of the lockout signal are inverted; - two independent safety contacts in series on the gas valve output; - auxiliary contact for low power ignition or main gas valve contrai for intermittent pilot systems; this contact is not isolated from the main supply voltage by reinforced isolation, therefore the relay contact is not suitable to supply SELV circuits - Safety Extra Low Voltage, e.g.24V; - flame monitoring by the rectification property of the flame: ionization. .!,f r-:-t ...- . . . - .: - -������L-,,t'-.- � .........i....., ·--=.:. . .·- -"'....
