Mounting and wiring
The wireless switch should be mounted on an even surface. The wire-
less range accordingly depends on the local conditions. Thus the radio
signal can be strongly affected by conductive materials. This also in-
cludes thin foils, e.g. aluminium laminations on insulation materials. A
test with the field strength indicator swView 868, mat. No. 1190393, or
swView 915, mat.No. 1221794, should be carried out (swView 922 and
swView 917 on request only).

Installation notes

Observe the installation notes of the applied sensors.
Design of wireless range
Because radio signals are electromagnetic waves the signal is attenu-
ated on its way from the transmitter to the receiver. This means the
electrical as well as the magnetic field strengths decrease and in fact
inversely proportional to the squared distance of transmitter and re-
ceiver (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. 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
Typical wireless ranges are:
Sight connection in free field:
Sight connection indoors:
Sight connection in free field (SW922):
Sight connection indoors (SW922):

Tightening torque

NOTICE
Too high tightening torques may damage the
threads of the external sensors and switches and
of the device.
Pay attention to low tightening torques.
M12: 10 Nm
M18: 25 Nm
M30: 75 Nm
N.B.
To avoid too fast actuation, there is, by default, a delay time of 1 s when
processing one switching command from transmitter to receiver (if the
radio interface is unoccupied and there are no repeat telegrams).
The switching signal of a transmitter must not be generated in shorter
time sequences otherwise this signal will be suppressed. The preset
delay time of 1s can be adjusted from min 125 ms to max. 31.9 s (see
RF RxT SW868/915/917/922-NET, »Description of interface/Wireless
receiver«, section »StateMessage-Response«, paragraph »RECORD.
CYCLETIME«, download from www.steute.co.uk). Subject to technical
modifications. Reconstruction and alterations to the device are not
allowed. .steute does not assume any liability for recommendations
made or implied by this description. New claims for guarantee, war-
ranty or liability cannot be derived from this document beyond the
general terms and conditions of delivery.
Safety notes
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.
The described device has been developed in order to assume safety
functions as a part of an entire plant or machine. It is the responsibility
of the manufacturer of a plant or machine to guarantee the correct
general function.
Maintenance and cleaning
.steute recommends routine maintenance as follows:
1. Remove all dirt particles.
Clean enclosure on the outside only. Clean enclosure with household
90...100%
cleaning agents. Do not use compressed air to clean.
65...95%
10...90%
Disposal
