2 CHECKING THE USAGE
IFD244/IFD258
For atmospheric burners or forced draught burners
used in multiple burner applications, where a central
control system is used for pre-purge and for mon-
itoring the limits. For direct ignition and monitoring
of gas burners in continuous operation. Suitable for
intermittent operation thanks to its fast reaction to
different process requirements. 2-digit 7-segment
display for indicating program status and flame
signal intensity.
IFD..I
With integrated ignition.
WARNING
– The user must ensure that the high-voltage
output (IFD..I) is protected against accidental
contact.
– The IFD..I may not be used for domestic,
commercial and trade, or small firm application
due to emitted electromagnetic interference.
IFD244
Gas burner monitoring with a flame rod. For ground-
ed mains. With restart after a flame failure.
IFD258
Gas burner monitoring with a flame rod or a UV
sensor.
In the case of UV control with UV sensors of Type
UVS, the IFD may be used for intermittent operation
only. This means that operation must be interrupted
once within 24hours.
Ionization control is possible in both grounded and
ungrounded systems.
Ignition and monitoring with a single electrode is
possible (single-electrode operation).
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 an automatic restart
occurs.
➔ Mains voltage, ambient temperature, safety
time, enclosure, and with IFD..I also the ignition
voltage (peak-peak) and ignition current– see
