Applicaion The auomaic burner conrol uni IFS 110 IM is suiable for he igniion and conrol of gas burners in gas firing insallaions of all ypes. This conrol is designed for high cycling frequency and long life, especially for indusrial applicaions. Muliburner conrol in conjuncion wih flame relay IFW 15 T (see leafle T ). Examples of applicaion Operaion wih one elecrode (Fig. 1) The igniion and conrol of he burner wih only one elecrode is possible when using igniion ransformers TZI or TGI. During he igniion, he high volage coil of he igniion ransformer is grounded via he burner conrol uni. For he flame conrol, he elecrode is swiched o he flame amplifier of he burner conrol via he high volage winding. Block diagram for direc spark igniion 2

As soon as he flame is esablished a small curren flows hrough i and is recified by he flame. The elecronic amplifying sage deecs only his direc curren signal which, afer amplificaion, is used o energize a relay. A flame canno be simulaed. The flame mus ouch he burner ube. High volage cable (no screened) should be used as ionisaion lead in order o avoid losses hrough insulaion: FZLSi 1/ order No The cable should be laid as far away as possible from power cords and sweep radiaion sources. Several ionisaion leads can be laid ogeher possibly in plasic pipes. Do keep away from he furnace wall for approx. 7 7 / (20 cm); his applies pariculary o long ionizaion leads up o 150 f (50 m). Flame conrol wih UV-deecor (Fig. 1) The UV-deecor (UVS or UVS ) mainly consiss of a ube which is sensiive o ligh and of elecronic componens. The ube responds o he ulra viole (UV) radiaion from a gas flame, i does no reac o sunligh and ligh from filamen lamps. Noe A d.c ammeer is pu ino he flame signal line in order o measure he flame signal curren. The amperage mus be a leas 1 µa and is usually beween 5 and 0 µa. Volage surges, shor-circuis or leakagepah in he flame signal line resul in an alernaing signal which will be regisered as a faul condiion wih boh ypes of conrol.
