Radio operation

If the distance falls above or below a predefined threshold, the device
sends a radio signal to the receiver. The transmission of a switching
command from the transmitter to the receiver takes about 80 to 100
ms, based on the sWave® data transmission. The switching signal
from a transmitter may not be generated at a shorter interval, other-
wise the signal will be suppressed. The preconfigured cycle time of 5 s
can be re-set using the Sensor Bridge to between min. 1 s and max. 31
s. Debounce time always equates to half the configured 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 distance is determined by measuring a light impulse. 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 object. 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 bat-
tery-driven system and thus to increase battery life, distance calcula-
tions are clocked. The standard values of 5 seconds cycle time and the
resulting 2.5 seconds debounce time represent a good compromise
between response time and battery life.

The battery voltage is displayed on the Sensor Bridge Interface under

»Sensors & Actors« in percent. In addition, the battery voltage is dis-
played in the logs in mV.
10...90 %
When the battery voltage acc. to the radio protocol drops below approx.
0...10 %
<3200 mV (at 20°C, load approx. 20 mA), it may be assumed that the
battery is empty. Attention: The open circuit voltage measurement
does not provide reliable information! In order to ensure reliable
functioning, the battery must be replaced. To do this, the 5 screws in
Wireless range (approx.)
the housing cover must be opened using a torx-8 screwdriver. The
450 m
battery should be inserted in the direction shown by the symbols on
the cover. Use only the designated battery type or a complementary
150 m
battery type. Depending on the country the device is supplied to, deliv-

adapter, or a lithium battery SL-2770/3.6 V/8.5 Ah without an adapter
or a complementary battery type. Once the battery has been changed,
the housing must be closed and the screws replaced, tightened with a
torque of approx. 0.45 Nm. The sealing must not be contaminated by
any foreign bodies.
