Photocell Detectors RAR...
The photocell detectors are designed for use with burner controls, for the super-
vision of yellow-flame oil flames.
They are used especially in connection with burner controls for the control and
supervision of large-capacity burners.
The RAR... and this Data Sheet are intended for use by OEMs which integrate the
flame detectors in their products!
Use The RAR... flame detectors are used for the supervision of yellow-burning oil flames.
They are designed for use with the following types of burner controls: LAL..., LAE1...,
LAE10..., LOK16..., LFS1.1...

Warning notes
To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
Do not open, interfere with or modify the flame detector!
All activities (mounting, installation and service work, etc.) must be performed by
qualified staff
Before making any wiring changes in the connection area, completely isolate the
plant from mains supply (all-polar disconnection). Ensure that the plant cannot be
inadvertently switched on again and that it is indeed dead. If not observed, there is
a risk of electric shock hazard
Ensure protection against electric shock hazard by providing adequate protection
for the connection terminals. If this is not observed, there is a risk of electric shock
Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring is in an orderly state. If this is not observed, there is a
risk of loss of safety functions and a risk of electric shock
Fall or shock can adversely affect the safety functions. Such flame detectors or
burner controls must not be put into operation, even if they do not exhibit any dam-
age. If this is not observed, there is a risk of loss of safety functions and a risk
of electric shock
Mounting notes
Ensure that the relevant national safety regulations are complied with
The flame detector plugs into the burner (the detector’s clamp engages on the
burner’s light metal flange)
Installation notes
Always run the high-voltage ignition cables separate from the unit and other cables
while observing the greatest possible distances
Electrical connection of the flame detector
It is important to achieve practically disturbance- and loss-free signal transmission:
Never run the detector cable together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable
Observe the permissible detector cable lengths (refer to Type summary and Tech-
nical Data)

Service notes Each time a unit has been replaced, check to ensure that wiring is in an orderly state
and that the wires are firmly connected.
Disposal notes The flame detector contains electrical and electronic components and must not be dis-
posed of together with household waste.
Local and currently valid legislation must be observed.

Function With this type of flame supervision, the radiation of oil flames in the visible band of the
light spectrum is used for generating the flame signal. The light-sensitive element is a
photocell. When illuminated, it generates DC voltage, causing a current to flow to the
input of the flame signal amplifier. Hence, the RAR... is an active detector. The photo-
cell is insensitive to infrared radiation so that glowing firebrick in the combustion cham-
ber cannot produce a flame signal.
