Intended use
The device essentially comprises three parts: the power supply with a
lithium battery, the wireless part with an integrated interface for the
external sensors and the connecting part for the external sensors. The
power supply is provided by a non-rechargeable 3.6 V lithium thion-
ylchloride battery. The battery status is transmitted with every signal
transmission. The interface for the external sensors is connected at
the M8 socket. Up to four external sensors type RF LDS SPOT, Material
No. 1208356, can be connected in total. The receiver must conform to
the sWave.NET® protocol of the steute modules.

Mounting and wiring

Mount the device on an even surface. Install the device according to
the mounting and wiring instructions of the receiver. The wireless
range depends heavily on the local conditions. Conductive materials
may strongly affect the radio signal. This also includes thin foils, e.g.
aluminium laminations on insulation materials.
Allocation of locations and radio frequencies:
Device type Radio frequency
SW868 868.3 MHz
SW915 915.0 MHz
SW917 917.0 MHz
SW922 916.5 MHz
Design of wireless range
The radio signal is attenuated on the way from the transmitter to
the receiver. In addition, the radio signal is attenuated/influenced by
obstacles. The degree of attenuation depends on the material of the
obstacle. The following tables serve as a guide.

Radio operation

The transmission of a switching command from the transmitter to the
receiver takes about 80 to 100 ms, based on the sWave® data trans-
mission. The switching signal from a transmitter may not be generat-
ed at a shorter interval, otherwise the signal will be suppressed. The
preconfigured cycle time of 10 s can be re-set using the Sensor Bridge
to between min. 2 s and max. 31 s. Debounce time always equates to
half the configured cycle time. The debounce time is valid for every
connected sensor. The number of connected sensors has no impact on
the debounce time and cycle time.
Safety
Do not use the device in connection with other devices whose direct
or indirect purpose is to ensure life or health, or whose operation may
pose a threat to humans, animals or material assets.
Maintenance and cleaning
.steute recommends routine maintenance as follows:
1. Remove all dirt particles: Clean enclosure on the outside only.
Clean device in accordance with IP protection class. Clean with
a soft cloth and water or a mild detergent. Do not clean using
compressed air.
2. Test the function.

Technical information

The connected external sensors measure distance by logging the
transit time of a light pulse. The time required for the light impulse to
travel to an object and back is used to calculate the distance based on
the speed of light. This measuring principle means that the switching
point is largely independent of the colour and material of the ob-
ject. The quantity of reflected light has no influence on the switching
distance, provided that sufficient light is reflected for the measuring
process. This is the case for conventional materials. With some porous
and very low-reflecting materials, it is possible that the full extent
of the switching distance cannot be used. Very strongly reflecting or
mirroring materials can lead to deviations in the switching distance. In
order to save energy when using a battery-driven system and thus to
increase battery life, distance calculations are clocked. The standard
values of 10 seconds cycle time and the resulting 5 seconds debounce
time represent a good compromise between response time and
battery life.
Up to four sensors can be connected to an RF 96 BU SW868/SW915/
SW917/SW922-NET-LDS. The individual sensors are assigned dynami-
cally to the transmitted data. A detailed functional description is avail-
able online at: www.nexy.net/docs. During normal operation, sensors
can be added or removed, which can impact how they are assigned.
Assignment is not impacted by a reset.
