9. FLAME SUPERVISION FOR OIL BURNER CONTROL (380IC 24/29)
9.1.4 Application
TheickerdetectorIR911/IR1010isusedforthesupervisionoftheoil
ameandisconnectedtoaSatronicoilorgasburnercontrol.Thesu-
pervisionfunctionisbasedontheinfrared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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ameindicationduringthepre-purgetime.
3. Takeoutthe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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inuenceofextraneouslightontheicker
detector,forexamplea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ameisefcientlysupervised.
A change of the burner adjustment because of dirt etc. or the
in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.
