During operation, the 7-segment display shows the program status, see page 16 (Program status and fault
messages).
The flame signal and all following parameters of the IFD can be scanned one after the other by repeatedly pressing
the Reset/Information button (for 2 s).
In the event of a fault, the IFD halts the program run, the display blinks and it then displays the cause of the fault in
coded form.
