Purpose and use
The wireless universal transmitter in series Ex RF 96 ST SW*** com-
plies with the standards for explosion protection IEC/EN 60079-0 and
IEC/EN 60079-11. It has been designed for the explosive areas of zones
1 and 2 as well as zones 21 and 22 as to IEC/EN 60079-14. The require-
ments of IEC/EN 60079-14, e.g. regarding dust deposition and temper-
ature limits, must be met.
The device of type SW868 is intended for use in the European Union. It
complies with the European Union's Directive 2014/53/EU (RED) for
radio equipment.
The device of type SW915 is intended for use in Canada, USA,
and Mexico.
Ex RF 96 ST SW*** consists of three parts: the energy supply with lith-
ium battery, the wireless part with integrated interface for the external
sensors and the connection part for the external sensors. Energy is
supplied with a not rechargeable 3.6 V lithium manganese dioxide bat-
tery and a nominal capacity of 2.1 Ah. Use a 4-pole M12 connector to
connect the device to an external sensor or switch. Ex Wireless induc-
tive sensors or other separately approved sensors or switches with
suitable function (function test by steute) are connectable. The me-
chanical switch must be equipped with a NO/NC contact. It must be
connected to plus (pin 1) and to the entry (pin 4). Exceeding the thres-
hold triggers a wireless signal. The battery status is transmitted with
every signal transmission. The transmission is carried out at a fre-
quency of 868.3 or 915 MHz. The receiver must conform to the sWave ®
protocol of the steute modules.
Mounting and wiring
Mount the wireless universal transmitter on an even surface. Fasten
with 2 x M4 cylinder head screws (at least 25 mm long). Set up the re-
ceiver in non-hazardous areas only. The wireless range depends on the
local conditions. Thus, the radio signal can be strongly affected by con-
ductive materials. This also includes thin foils, e.g. aluminium lamina-
tions on insulation materials. In individual cases, carry out a test with
the field strength testing tool swView 868 MHz, Material No. 1190393,
or swView 915 MHz, Material No. 1221794. Use the field strength test-
ing tool in non-hazardous areas only (near the receiver).
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 inversely
proportionally to the squared distance of transmitter 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. 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:

WARNING
Danger caused by electrostatic discharge.
Explosion hazard! Ignoring this message may
lead to serious injuries or death.
Avoid electrostatic discharge.
- For use in potentially explosive gas atmospheres, the wireless uni-
versal transmitter must be set up in such a way that dangerous elec-
trostatic charging is not to be expected.
- For use in dust explosion hazardous areas, the wireless universal
transmitter must be set up in such a way that sliding handle bush
charges are not to be expected.
- The wireless inductive sensors type EX RF IS M** nb-ST Xm are to
be included in the equipotential bonding via installation in a metal
holder, see Fig. 1.
- The external sensors must be included in the equipotential bonding.
N.B.
The processing of one switching command from transmitter to re-
ceiver lasts approx. 80 to 100 ms on basis of the sWave® data trans-
mission. The switching signal of a transmitter must not be generated
in shorter time sequences otherwise this signal will be suppressed.
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, warranty or liability cannot be derived from this document
beyond the general terms and conditions of delivery.
Maintenance
With rough conditions, we recommend routine maintenance
as follows:
1. Remove all dirt particles.
2. Clean with a damp cloth only.
3. To replace the battery:
- Loosen the cover screws with a wrench.
- Remove the cover.
- Insert the battery according to the positive terminal marking.
- Mount the cover.
- Insert the cover screws.
- Tighten the cover screws.
