9. FLAME SUPERVISION FOR OIL BURNER CONTROL (380IC 24/29)
9.1.4 Application
The fl icker detector IR 911/IR 1010 is used for the supervision of the oil
fl ame and is connected to a Satronic oil or gas burner control. The su-
pervision function is based on the infra red fl icker principle, i.e. only infra
light is sensed and it does not react to the even radiation from the brick
lining, if any, in the boiler.
9.1.5 Technical Data
Ambient temperature: -20...+60°C
Insulation standard: IP 41
Mounting position: optional
Weight: 40 g
Mounting of the fl icker detector: axially or radially
Spectral range: 800 - 1100 nm
Max. sensitivity: 950 nm
Frequency: 16 - 300 Hz
Max. sensitivity: 60 Hz
9.1.6 Commissioning and maintenance
On commissioning of the installation and after service ensure that the
work has been carried out in the correct way:
1. Check that the oil burner control is correctly connected. Faulty connec-
tions jeopardize the safety and may cause damage to the oil burner
control and the installation.
2. Adjust max. sensitivity and start the burner: After the initial start there
must not be any fl ame indication during the pre-purge time.
3. Take out the fl icker detector when the burner is in operating position
and cover it well: The indication must go back to zero. The oil burner
control locks out or goes to repetition.
4. Re-start with covered fl icker detector: There must be no indication. The
oil burner control must lock out when the safety time has expired.
5. Start the burner under the infl uence of extraneous light on the fl icker
detector, for example a fl uorescense lamp, cigarette lighter, bulb
(daylight is not strong enough): The oil burner control must lock out
because of extraneous light (immediately or after the end of the pre-
purge period depending on type of control).
6. When the burner is in operation carefully turn the potentio
meter back from max. until LED 2 goes out. Then increase
by one or two markings so that both LEDs are on. With this
adjustment the quality of the fl ame is effi ciently supervised.
A change of the burner adjustment because of dirt etc. or the
infl uence of extraneous light is easily noticeable.
Satronic IR 911/IR 1010 does not need any maintenance. As
it is a safety device it is prohibited to open it.
LED 2 LED 1
Burner in operation= both LEDs on
Burner in pre-purge= both LEDs off
