1 Application
Automatic burner control unit IFD 258 ignites and monitors
directly ignited industrial gas burners of unlimited capacity.
As a result of its fully electronic design it reacts quickly to vari-
ous process requirements and is therefore also suitable for
frequent cycling operation.
It can be used for atmospheric burners or forced draught burn-
ers in multiple burner applications, where a central control
system is used for pre-purge and for monitoring. The burners
may be modulating or stage-controlled.
The program status and the level of the flame signal can be
read directly from the unit. The cut-off point can be set using
a potentiometer.
The behaviour in the event of flame failure during operation
can be selected using a switch. Either an immediate fault
lock-out or a restart occurs.
