Ignition 4- Funktionsbeschreibung_Ueberwachungen_Zuendung
The ignition transformer is activated via the "IGNT" output.
You can select two types of ignition in the PNOZmulti Configurator:
 Direct ignition
With direct ignition, no separate ignition burner is present. The main
burner is ignited directly via the ignition transformer.
 Indirect ignition
With indirect ignition, a separate ignition burner is present. The main
burner is ignited by an ignition flame, which is ignited via an ignition
transformer. Fuel may not be supplied to the main burner until the ig-
nition burner has been ignited and the ignition flame is stable.
The ignition valve is activated via the IV output.
The following setting options are available for the behaviour of the ig-
nition flame:
– Ignition valve is closed after ignition,
i.e. the ignition flame is to be extinguished once the main burner is
successfully ignited, or
– (only possible when separate flame monitoring is configured (see
section entitled "Flame monitoring")): Ignition valve remains open
after ignition,
i.e. the ignition flame is to stay lit once the main burner is success-
fully ignited.
The ignition valve must be positioned as follows:
