Basic safety notes
Intended use
The RSS radio system serves to transmit the sensor states via a ra‐
dio link from the transmitter unit to the receiver in the switching
cabinet.
The product is intended for installation in a machine/system. The
requirements of the applicable guidelines must be observed and
complied with.
The product may be used only in the context of its defined applica‐
tion parameters (6, Page 13).
The product is designed for industrial use.
To use this unit as intended, it is also essential to observe the
technical data and installation and operation notes in this manual
and to comply with the maintenance intervals.
Environmental and operating conditions
• Make sure that the product has a sufficient size for the applica‐
tion.
• Make sure that the environment is free from splash water and
vapors as well as from abrasion or processing dust.
• The radio link established by the system can experience tempo‐
rary or permanent interference through external influences. As
a result, the states of the sensors are not updated at the re‐
ceiver for the duration of the interference. The interference is
only reported by the receiver after the watchdog time has
lapsed. Ensure that such interferences cannot cause any dam‐
age. Adjust the watchdog time to a time suitable for your pro‐
cess.
• In the 868.3 MHz range, the system does not comply with the
EMC regulation for interference immunity to incoming radio
waves. Losses of radio telegrams may occur in this range. Dis‐
turbances become more likely if the antenna is further than 25
cm away from the receiver. The application must therefore be
tested each time before being integrated.
• The radio switch receiver must not be used in combination with
devices that are directly or indirectly used to safeguard the
health or life of per‐sons, or devices which, when in operation,
could cause danger to persons, animals or property! This is due

Information on radio link and range
The transmitter sends telegrams with 868 MHz to the receiver. The
receiver checks the incoming telegrams and uses them to control
its outputs.
This radio link is principally prone to interferences by other radio
systems or systems emitting radio signals. For reasons of availabil‐
ity, the presence of systems emitting radio waves – such as wire‐
less or mobile phones or PCs – in the immediate proximity of the
transmitter is to be avoided. We recommend observing a mini‐
mum air distance of at least one meter between receiver and in‐
terference source or between transmitter and interference source.
Since the radio signals represent electromagnetic waves, the signal
is damped on its route to the receiver. This means, the signal
strength decreases with increasing distance between transmitter
and receiver. Thus, the radio range is limited. In particular, the
range will also be significantly limited in case of irradiation above
400 MHz.
It must also be noted that the radio range is reduced by materials
between transmitter and receiver. For the practical application,

this means that the construction materials used in buildings and
facilities (machines) play an important role for the evaluation of
the radio range. Some reference values that can be used to esti‐
mate the range are:
• Line of sight
– Typically 30 m range
• Concrete or brick walls
– Typically 20 m range
• Steel‐reinforced concrete walls
– Typically 10 m range
• Fire protection walls, elevator shafts ..
– Can be considered blockages.
• Turning centres
– The radio waves penetrate to the outside through various
slots and especially through the viewing glasses. It is difficult
here to make an exact statement on the range. Based on
our experience, a range of at least 3 m must be expected.
• Cordless telephone at a distance of less than 1m
– Range approx. 25 cm
The distance from the receiver to other transmitting devices also
radiating high‐frequency signals (computers, video systems, etc.)
should be at least 0.5 m.
Using the receiving strength LED (SI) to our receiver it is easy to
decide whether the system provides secure transmission for the
intended location or if strong interferences are present.

Assembly

Assembly
Assembly of the transmitter RSS T2
1 Install the housing in a suitable position next to the sensor fas‐
tening using two screws M4.
2 ‐ Install the sensor (closer) at the gripper.
3 Fasten the M8 sensor plugs with screws to the transmitter.
4 For adjustment of the sensors the magnetic brackets of the
transmitter can be plugged into ‘test mode‘ position. Now you
can see the individual sensors’ status on the LEDs. Position the
sensors at a suitable position and finally screw the magnetic
switch onto the ‚normal mode‘ position.
5 Never leave the magnetic bracket in ‘test mode‘ position, oth‐
erwise the battery of the transmitter will be discharged within
a few days!
NOTE
Always use closers. Otherwise the system cannot recognize a
changing status of the sensors, i.e. if a sensor is open while the
signal of another sensor changes.
Assembly and electrical connection of the RSS R1 receiver
1 Mount the receiver in a switching cabinet located less then 10
m from the transmitter by snapping it onto a DIN track
(EN50022).
2 Connect the receiver:

Start‐up
General information on commissioning
Before commissioning, please check the device for any transport
damages. Do not start up the device if it is mechanically damaged.
Please read this assembly and operating manual carefully and ob‐
serve the technical information as well as the legal requirements
relevant to your country.
NOTE
The components are equipped with electronic elements which
could be destroyed in case of an electrostatic discharge. When
handling the components, it must be ensured that environment
(persons, workstation and packaging) are proper
ly grounded. Do
not touch conductive elements.
Notes on installation
When installing the antenna and antenna cable assembly group, it
is imperative to avoid any proximity to sources with transient dis‐
turbances such as fluorescent tubes with a faulty starter, frequen‐
cy converters or power cables. They could result in interrupted
communication and therefore lead to incorrect initial states.
Notes on connecting the antenna
Only use suitable antennas (e.g. WAGO 758‐910 incl. 2.5 m RG174
connection cable and SMA connector; see accessories). The an‐
tenna must be fixed on a plate with the minimum dimensions of
25 cm x 25 cm. The antenna and the antenna cable must be at
least 30 cm away from sources of interference and the antenna
must be at least 35 cm away from the next wall at the side. The
antenna cable must under no circumstances be bent sharply as
this could result in permanent damage to the antenna cable
(RG174 bending radius > 15 mm).
Preconditions for commissioning
The voltage supply must be applied and the external antenna must
be connected prior to commissioning.
Programming the transmitter to the receiver
1 Switch DIP 1 to ‘on’ and immediately back to ‘off’.
2 to energize the sensor from the transmitter.

3 Wait for 15 seconds.
4 Now, the receiver should indicate the condition of the sensors
by means of the LEDs. Anymore the WD LED lights up briefly
approx. every 10 seconds.
5 Please try a second time if the learning procedure has failed.
Ideally, no second RSS system should radio in the immediate
vicinity during the learning phase.
Testing the antenna position
1 Observe the LED ‘SI’. This LED signals the current quality of the
radio link. This LED should preferably light up or blink green.
2 If necessary, move the antenna closer to the transmitter or
reposition the antenna to avoid any solid obstacles between
antenna and transmitter.
Adjusting the watchdog time at the receiver
1 Adjust watchdog time to best suit your process. The transmit‐
ter transmits a presence signal every second to monitor the
transmission path. If no signal is received for longer than the
set watchdog time, the 'WD' LED lights up until the next signal
is received. The 'WD' output then signals through 0 VDC the
down‐time of the transmission path.
2 Switch Dip 4 to on.
3 Turn the potentiometer clockwise to extend the time. The set
time can be determined from the flash rate of the WD LED.
With DIP 8 switched off, the time can be varied between 0 and
one second. SCHUNK recommends setting the time to 15 sec‐
onds with DIP 8 switched on.
4 Switch DIP 4 to 'off' (leave DIP 8 in the selected position!).
