English
The RF 96 LT essentially comprises three parts: a power supply with a
lithium battery, an infrared reflective sensor and a radio part with an
integrated interface for the sensor technology. Power is supplied by a
non-rechargeable 3.6-V lithium-thionylchloride battery. When an invis-
ible infrared flash is sufficiently reflected, a radio signal is triggered.
The voltage status of the battery is also communicated with every
transmission. It is possible to transmit a status signal at regular in-
tervals which communicates the current switching state of the sensor
independently of a change in the switching state. The transmission is
carried out at a frequency of 868.3 MHz (EU) or 915.0 MHz (USA, Can-
ada, Mexico) or 917.0 MHz (Brazil) or 916.5 MHz (Japan). The receiver
must support the sWave protocol of the steute modules.

Status signal
A status signal can be set by the user at various intervals with the
jumper. To do this, open the enclosure by removing the 5 cover screws
using a Torx 8 screwdriver. Take care to ensure sufficient ESD protec-
tion. Inside the enclosure a jumper is located on the circuit board. Ad-
just to the desired interval. For evaluation of status signals, steute pro-
vides special receivers.

After successful adjustment, replace the enclosure cover and tighten
the cover screws with approx. 0.45 Nm. Take care to ensure that there
is no debris trapped in the seal.
Mounting / Wiring
Mount the reflective light sensor on an even surface. The device
must be installed according to the mounting and wiring instructions
of the receiver. The wireless range accordingly depends on the lo-
example position 1:

cal conditions. Thus, the radio signal can be strongly affected by
conductive materials. This also includes thin foils, e.g. aluminium
laminations on insulation materials.
Design of wireless range
Because radio signals are electromagnetic waves, the signal is
attenuated on its way from the transmitter to the receiver. This
means that the electrical as well as the magnetic field strengths
decrease inversely proportional to the squared distance of transmit-
ter and receiver (E,H~1/r²). In addition to this natural restriction of
the wireless range, further interference factors occur: Metal parts,
e.g. armours in walls, metal foils of thermal insulations or vapour
deposited metal layer heat protection glass reflect electromagnetic
waves. Therefore, a so-called deadspot can be found behind them.
Indeed, radio waves are able to penetrate walls, but the attenuation
increases even more than in the free field.
Penetration of radio waves:
wood, gypsum, glas uncoated
brick stone, press boards
armoured concrete
metal, aluminium lamination, water

Safety
The device must not be used in connection with other devices whose
direct or indirect purpose is to ensure life or health, or whose opera-
tion may pose a threat to humans, animals or material assets.
Maintenance
With rough conditions, we recommend routine maintenance as follows:
1. Remove all dirt or particles.
2. Remove dust from sensor surface.
Cleaning
- In case of damp cleaning: use water or mild, non-scratching,
non-chafing cleaners.
- Do not use aggressive cleaners or solvents.
Clean enclosure on the outside only. Clean enclosure with household
cleaning agents. Do not use compressed air to clean.
Technical information
The infrared transmitters and receivers in steute reflection light
sensors are located next to each other behind a filter in the housing
cover, both pointing upwards. A short infrared flash is emitted approx.
5 times per second. Reflective light sensors detect an object as soon
as they sense sufficiently reflected light from its surface. When an
object is detected, the sensor generates a defined electrical output
signal. A light surface reflects more light than a dark surface and can
therefore also be detected from a greater distance. In order to achieve
