2.1 Intended use
The IFC 400 is a compact flame detector that has been specially designed for industrial com-
bustion furnaces for continuous operation. It provides a galvanically isolated change-over
contact as safety-related output.
As a safety-relevant criterion for flame detection, the flickering of the flame is used. Swit-
ching thresholds, switching times and filter characteristics can only be set by the manufac-
turer.
The flame detection is signaled via a LED and data is transmitted for evaluation.
2.2 Requirements on persons
Do not allow any persons who are being apprenticed, educated, instructed or on a general
training programme to work on the device without the constant supervision of an experien-
ced person.
Persons who are under the influence of drugs, alcohol or medication that affects reactivity
shall not be permitted to carry out work on the device.
Connection, set-up, maintenance and repair work may only be carried out by qualified spe-
cialist staff.
This device may cause hazards if it is operated inappropriately by untrained staff or if it is not
used for its intended purpose.
The Compact Flame Detector IFC 400 may only be operated with a burner control or a
DCS. It is not approved for direct control of the fuel valve!
Danger due to improper use!
The device may be dangerous if used improperly and / or otherwise.
Only use the device as intended.
Follow the procedures described in this operating manual.
The manufacturer / supplier is not liable for damage resulting from improper use. The
risk is borne solely by the user / operator.
Work on/with the device may only be performed by persons authorized to do so based
on their training and qualification. Furthermore, such persons have to have been com-
missioned by the operating company.

Important rules of conduct
• Check the device at regular intervals. Any defects or faults ascertained have to be corrected
immediately. Switch off the device until the defects have been corrected.
• Equipment undergoing inspection, maintenance or repair work must be deenergised, if re-
quired. First check that the disconnected parts are no longer live, then short to earth. Also
isolate neighbouring live parts.
• If work is required on live parts, a second person must be present to disconnect the power
supply in case of an emergency. Only use insulated tools!
• Fuses must not be repaired or bridged. Only use original fuses with the specified current!
• Before opening the housing, the device must be deenergized.
2.5.3 Testing per German Workplace Safety Ordinance (BetrSichV)
In case of the coupling or installation of devices from various manufacturers or suppliers,
the operating company has to carry out a precise test, prior to start-up, in accordance with
the German Workplace Safety Ordinance (BetrSichV) in force and the applicable electrical
regulations.
In case of queries, please get in touch with BST Solutions.
2.5.4 Safety test
In order to ensure correct operation, the compact flame detector IFC 400 of all applica-
tions have to be tested several times by starting and stopping the burner several times.
In all cases the flame relay has to be switched off reliably in case of an absent flame.
The test should be performed in different operating situations. This is an indispensable
pre-requisite for a safe and correct operation of the device!

4.4 Dimensions IFC 400
All dimensions in mm
4.5 Installation
The IFC 400 should be installed as close as possible to the flame with low vibration. The
alignment is to concentrate on the primary zone of the flame (flame root). The compact
flame detector should be mounted with the adapter. In order to prevent interference, the
direct view of a spark is to be avoided.
The connecting cable is to run separately from the high-energy ignition and power lines over
long distances and not parallel to avoid interference.
All installation and connection work may be carried out by qualified and approved spe-
cialist staff only! The legal regulations as well as adjustment instructions of the plant
operator have to be observed!
NOTICE
TRANSPORT, INSTALLATION AND CONNECTION
The cable length when using the ionization circuit depends on the used burner control.
For connection length > 1.5 m, the wires of the relay contacts in the connection cable
must be shielded.
NOTICE

BST Solutions GmbH | COMPACT FLAME DETECTOR IFC 400 Page 16
4.5.1 Alignment of IFC 400
4.5.2 Usage of glasses and lenses
Depending on the distance and viewing angle to the flame, the adapter lens to be used when
needed. If pressure is prevailing in the combustion chamber, an adapter with quartz glass is
recommended.
4.5.3 Purge air connection
If the sensor temperature may rise due to high combustion chamber temperatures above
60°C, a purge air connection in order to limit the temperature sensor to provide a maximum
of 60°C is essential. The dimensioning of the scavenging air is dependent on the parameters
of the furnace back pressure, and the pending purge air pressure and temperatures. Purge air
connections are available as the diameters ¼‘‘ and ½‘‘ optionally. The air connection is com-
bined with the adapter. Depending on the application again lenses and glasses are available.
This eliminates the normal adapter.
