• Ensure that the area surrounding the receiver is free of sprayed
water and vapors, as well as free of dust from abrasion or
processing.
• The transmission path established by the system can be
disrupted by exterior influences temporarily or permanently.
This means that the conditions of the sensors at the receiver are
not updated for the duration of the interference. The
interference is only reported by the receiver once the watchdog
time has elapsed. It must be ensured that such interference
cannot cause damage. The watchdog time must be set for a
period of time suitable for the process.

03.00 | Radio sensor system RSS | Assembly and Operating Manual | en | 0389609
• Within the range of 868.3 MHz, the system does not correspond
to the EMC regulation for radio wave penetration immunity. A
loss of wireless telegrams may occur in this range. If the
antenna is at a distance of over 25 cm from the receiver, the
probability of interference increases. The application must
therefore be tested before it is integrated into a machine.
• Wireless switching receivers may not be used in conjunction
with devices that directly or indirectly serve human, health or
life saving purposes or that may endanger people, animals or
property when operated! This is the result of the classification
of the radio switching receiver in "Class 2 Equipment" according

3.3 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 availability,
the presence of systems emitting radio waves – such as wireless or
mobile phones or PCs – in the immediate proximity of the transmitter
is to be avoided. We recommend observing a minimum air distance
of at least one meter between receiver and interference 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
estimate 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.

5 Start-up
5.1 General information on commissioning
Check for any damage caused during transport before
commissioning the product. In the case of mechanical damage, the
product may not be put into operation. Read the Assembly and
Operating Manual carefully, observe the technical information and
the applicable national legal requirements.
NOTE
The components are loaded with electronic components which
may be destroyed by electrostatic discharge. When dealing with
the components, a good earthing of the surroundings (people,
workstation, packaging) must be ensured. Do not touch electrical
components.
Installation notes
When installing the assembly group, antenna and antenna cable, it
is imperative to avoid proximity to sources with transient
interference, e.g., fluorescent tubes with a defective starter,
frequency converters and power cables. These may lead to
communication interference and in turn erroneous default
statuses.
Information on the antenna connection
Only use suitable antennas (e.g. WAGO 758-910 incl. 2.5 m RG174
connection cable and SMA connector; see accessories). The
antenna must be mounted on a metal sheet with minimum
dimensions of 25 x 25 cm. The antenna and antenna cable must be
at least 30 cm away from sources of interference and have at least
35 cm clearance between the side and the next wall. Under no
circumstances may sharp kinks be allowed to form in the antenna
cable, as this would cause irreversible damage to the antenna
cable (RG174 bending radius > 15 mm).
Prerequisites for commissioning
The voltage supply and the external antenna are connected.

Start-up
18
03.00 | Radio sensor system RSS | Assembly and Operating Manual | en | 0389609
5.2 Programming the transmitter to the receiver
NOTE
Programming may fail in the event of an unfavorable combination
of transmitter and receiver or due to external interference. The
programming may therefore need to be repeated multiple times.
ØUnscrew the antenna of the RSS-R1 (receiver).
ØFor the best possible programming, deactivate all other RSS-T2
(transmitters) within 15meters.
ØPlace the RSS-T2 (transmitter) 0.5meters away from the RSS-R1
(receiver).
ØPut the RSS-T2 (transmitter) into test mode (recommended by
SCHUNK) or normal mode.
ØChange DIP switch 1 on the RSS-R1 (receiver) to "ON" and then
immediately back to "OFF".
✓The receiver is now in Teach mode.
ØToggle the input D01 on the RSS-T2 (transmitter) to establish a
connection between transmitter and receiver (e.g. by moving
the product to be received multiple times).
Register in the RSS-R1 (receiver)
The RSS-R1 (receiver) has an integrated register. It is used to save
learned transmission units. This can be deleted upon a battery
change, or as required. To do this, disconnect the voltage supply of
the receiver for at least one minute.
5.3 Testing the antenna position
ØObserve the LED ‘SI’. This LED signals the current quality of the
radio link. This LED should preferably light up or blink green.
ØIf necessary, move the antenna closer to the transmitter or
reposition the antenna to avoid any solid obstacles between
antenna and transmitter.
5.4 Adjusting the watchdog time at the receiver
ØAdjust watchdog time to best suit your process. The transmitter
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.
ØSwitch Dip 4 to on.
ØTurn 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
seconds with DIP 8 switched on.
ØSwitch DIP 4 to 'off' (leave DIP 8 in the selected position!).

6 Functional description
6.1 RSS-R1
6.1.1 General discription
Block diagram of the receiver
A power supply of 12 to 24 V DC is required to operate the
wireless receiver. It is connected using plug connectors with Cage
Clamp® connections. An external magnetic antenna is required to
receive wireless telegrams for the frequency range of 868 MHz.
The wireless receiver is based on the EnOcean STM 300 wireless
receiver, whose received data are processed with a downstream
micro-controller.
The program in the micro-controller can be divided into the teach-
in and operating modes.

Functional description
20
03.00 | Radio sensor system RSS | Assembly and Operating Manual | en | 0389609
Teach-in mode
In teach-in mode (activated by DIP 1 ON/OFF), the ID of a detected
EnOcean telegram is stored in the receiver and the teach-in mode
is automatically ended. If no valid telegram from a transmitter is
received in the teach-in mode after 15 s have elapsed, this is
signaled as a faulty status. Alternatively, the transmitter ID can be
taught manually in the INACTIVE status by actuating the DIP switch
3 & 4 (simultaneously!).
The monitoring time and limit value can either be set by specifying
the default values or by means of a potentiometer using a
diagram. The diagrams and DIP switches are described in the
subsequent chapters.
Operating mode
In operating mode, the receiver monitors the incoming signals of
the transmitter using the watchdog function. The watchdog LED
(WD) displays each incoming telegram of the taught-in transmitter
with a short flicker. If the watchdog time is exceeded, the WS LED
signals a fault with a continuous light; the WD output goes to LOW
status.
The DO1 and DO2 LEDs and outputs directly display the condition
of the two-channel sensor. For each telegram, the current battery
level is monitored using the level control to an adjustable limit
value. If the minimum limit value is not reached, the output goes
into the LOW status and the LED is OFF.
The signal strength of incoming telegrams is displayed by flashing
codes using SI LED, which can be used to establish an optimal radio
connection during commissioning.
