1 Application
 
Automatic burner control unit IFD 258 ignites and moni- 
tors directly ignited industrial gas burners of unlimited 
capacity. As a result of its fully electronic design it reacts 
quickly to various process requirements and is therefore 
also suitable for frequent cycling operation.
 
It can be used for atmospheric burners or forced draught 
burners in multiple burner applications, where a central 
control system is used for pre-purge and for monitor- 
ing. The burners may be modulating or stage-controlled. 
The automatic burner control is suitable for operation in 
grounded and ungrounded  systems.
 
The program status and the level of the flame sig- 
nal can be read directly from the unit. The switch-off 
threshold can be set using a  potentiometer.
 
The behaviour in the event of flame failure during op- 
eration can be selected using a switch. Either an imme- 
diate fault lock-out or a restart occurs.
