1 Safety

1.1 Symbol key

- hazards for persons or damage to the product are possible

- important information on the product or its handling

1.2 Appropriate use

The RSS radio system serves to transmit the sensor states via a radio link from the
transmitter unit to the receiver in the switching cabinet.

For the RSS P1 system, this specifically involves monitoring the pressure in the chuck.
The system’s task is to detect a proper working pressure when clamping the work piece
from the outside. This way, a secure clamping can be ensured. Furthermore, it is possible
to detect pressure loss in the system in due time.

The unit must only be used within the scope of its technical data. Appropriate use also
includes compliance with the conditions the manufacturer has specified for
commissioning, assembly, operation, environment and maintenance. Using the unit with
disregard to even a minor specification will be deemed inappropriate use. The
manufacturer assumes no liability for any injury or damage resulting from inappropriate
use.

1.3 Safety information

This manual describes the function, application and safety considerations of this
product. This manual must be read and understood before any attempt is made
to install or operate the product, otherwise damage to the product or unsafe
conditions may occur.

This device complies with part 15 of the FCC Rules and with RSS-210 of Industry
Canada. Operation is subject to the following two conditions.
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.

1.

The radio link established by the system can experience temporary or permanent
interference through external influences. As a result, the states of the sensors are not
updated at the receiver 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 damage. Adjust the watchdog time to a time suitable for
your process.

The customary standards for sensor systems must be observed.
Installation and commissioning may only be performed by qualified staff trained for
electrical system.

Assembly and Operating Manual

Radio - Pressure - Monitoring RSS R1; RSS P1

date printed: 04.12.20065

2.

In the 824 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.

Disturbances 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.

3.

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 persons, or devices
which, when in operation, could cause danger to persons, animals or property!
This is due to the radio switch receiver’s classification as “Class 2 Equipment” in
accordance with ETSI EN 301 489-3 V1.4.1 (2202-08) “Specific conditions for
short-range devices (SRD)”.

4.

When the chuck is in operation, sudden surges in pressure may occur in the piston area
of the chuck. If the switching pressure set is exceeded due to these pressure
fluctuations, then the system sends this information. Thus, a very short “Pressure IO”
message may arise during the clamping process.

5.

Even if the air supply is switched off, there may still be pressure present at the pressure
switch if the chuck was not bled. It is imperative that the pressure chamber be bled
before the pressure switch is disassembled. The chuck must be opened for this
purpose.

The time between evaluable telegrams must be at least 50ms.

6.

The RSS R1/P1 receiver/transmitter has been built according to the current state of the
art and is operationally safe. The unit can only pose hazards if, for example:

- the unit is used, assembled or maintained inappropriately.

- the unit is used for purposes other than those for which it is intended.

- the EC Machine Directive, the accident prevention regulations, the VDE guidelines,

or the safety information and assembly notes are not observed.

7.

All persons responsible for assembly, commissioning and maintenance of the unit are
obliged to have read and understood all the operating instructions, in particular the

Safety chapter. We recommend that the customer have this confirmed in writing

8.

The installation and deinstallation, connection and commissioning of the unit may only
be performed by authorized, appropriately trained personnel.

9.

Modes of operation and work methods that adversely affect the function and/or the
operational safety of the unit are to be refrained from.

10.

The RSS R1/P1 receiver/transmitter may only be used to control chucks within the
scope of its technical data. Any use outside this scope is deemed to be inappropriate.
The manufacturer assumes no liability for any injury or damage resulting from such
inappropriate use.

11.

Always disconnect the power supply lines during assembly, conversion,
maintenance and adjustment work.

12. Additional holes, threads or attachments which are not supplied as accessories
by SCHUNK may only be applied after obtaining the prior consent of SCHUNK.

13.

To avoid severe personal injury or substantial property damage, only qualified
persons may work on the devices. These persons must conscientiously read the
operating instructions and observe the safety notes before installation and
commissioning. (Cf. IEC 364 or CENELEC HD 384 or DIN VDE 0100 and IEC report
664 or VDE 0110 and national accident prevention regulations or VBG 4.)

14.

Repairs to the RSS R1/P1 receiver/transmitter may only be carried out by the
manufacturer or repair centers authorized by the manufacturer. Unauthorized
opening and inappropriate tampering may lead to personal injury or property
damage.

15. Make absolutely sure that the operator is not injured (crushed) while clamping or
unclamping the chuck. We recommend you enable the >>Clamping<< or
>>Unclamping<< functions of the chuck only when the system door is closed.

16.

4.3 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 centers

- 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 First Steps

5.1 Assembly

5.1.1 Assembly of the RSS P1 transmitter module

You have received the system completely assembled. The following assembly instructions
are intended for maintenance that may be needed.

- Roll out pressure monitoring kit MATCH code “DAF...” (transmitter unit 8703653,

pressure switch 9941145, seal and cover for pressure switch).

- An electrostatic discharge via the cable at the transmitter unit must be prevented. The

installation engineer must ground himself/herself at the chuck accordingly. During the
entire assembly process, the chuck must remain on a grounded base.

- Lay the cable of the transmitter unit in the bores of the chuck body so that the end can

be pulled out in the bore in the side for the pressure switch.

- When you pull out the cable, it must not be pulled over sharp edges.

- The cable must not be laid taut in the chuck body; otherwise it will be damaged during

the rotation.

- Push the transmitter unit carefully into the recess in the chuck. In the process, feed the

cable accordingly to the bores at the chuck to the recess for the pressure switch. Make
sure the cable is not pinched or damaged.

- Install the pressure switch into the chuck using the proper wrench and solder on the

‘brown’ and ‘black’ wires at the pressure switch.

5.1.2 Assembly and electrical connection of the RSS R1
receiver

- Mount the receiver in a switching cabinet located less then 10 m

from the transmitter by snapping it onto a DIN track (EN50022).

- Connect the receiver:

Antenna socket X1:

- SMA socket for external antenna (we recommend

our RSS-R-A antenna, ID°No. 0377730)

Connector X2:

- X2.1 FE Function ground

- X2.2 + Suppply DC 24DCV+external

- X2.3 - Supply DC 24V-external

Connector X3:

- X3.1 WD Output watchdog, high signal, if radio IO

- X3.2 LC Output limit value, high signal, if battery IO, i.e. has still more

than 2 weeks capacity remaining.

- X3.3 DO1 Output 1, reserve, no function here.

- X3.4 DO2 Output 2, high signal, if clamping pressure is insufficient.

- X3.5 GND Reference ground for the outputs, type

Recommendation:

If the clamping pressure is insufficient (D02=High), or if the radio link is
interrupted (WD=Low), it is imperative to shut down the spindle for safety
reasons.

5.1.3 Switching suggestions on connecting to your system

Variant 1, if your system has digital inputs available.

WD on Input 1. This must be high; otherwise the radio communication is interrupted.
D02 on Input 2. If this is high, then the pressure is insufficient.

Adapt the system’s software so that the spindle can only turn if E1= High and
E2= Low. Continue to check for each cycle that E2= High must be the case if
the chuck is opened. This way the proper function of the inputs and outputs can
be ensured.

Variant 2, if your system only has the preprogrammed input ‘Release spindel’.

5.2 Commissioning

5.2.1 General information

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 observe the technical information as well as the legal requirements
relevant to your country.

ESD Information

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 properly
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 disturbances such as fluorescent tubes with
a faulty starter, frequency 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 antenna 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 inter-

ference 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.

5.2.2 Programming the transmitter to the receiver

(1) Switch DIP 1 to ‘on’ and immediately back to ‘off’.
(2) Open and close the chuck completely twice.
(3) Wait for 15 seconds.
(4) The transmitter and the receiver should now be taught. Check this by observing whether

the WD LED lights up briefly approx. every 10 seconds. Carry out a second test by
completely opening and completely closing the chuck. The WD LED should then light up
once briefly in each case. Furthermore, the status should be displayed on the LED D02.

Assembly and Operating Manual

Radio - Pressure - Monitoring RSS R1; RSS P1

date printed: 04.12.200613

- The LED D02 indicates: Off if the pressure set is exceeded. Pressure switch closed.

à It is safe to work. If the LED lights up: Warning, the pressure is too low or the chuck is

open.

- 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.

5.2.3 Testing the antenna position

- Observe the LED ‘SI’. This LED signals the current quality of the radio link. This LED

should preferably light up or blink green.

- If necessary, move the antenna closer to the transmitter or reposition the antenna to

avoid any solid obstacles between antenna and transmitter.

5.2.4 Adjusting the watchdog time at the receiver

- You should adapt the watchdog time to your process in a useful manner. Every 10

seconds, the transmitter transmits a presence signal to control the radio link. If no signal
is received after the watchdog time set has elapsed, the LED ‘WD’ lights until the next
signal is received. The ‘WD’ output then signals the failure of the radio link through
0 VDC.

- The production facility has preset a time of about 15 seconds. This value should be

optimal for applications of the radio system in the chuck.

- Switch DIP 4 to ‘on’.

- To increase the time, turn the potentiometer clockwise. The time set can be identified by

the blinking frequency of the WD LED. When DIP 8 has been switched off, the time can
be adjusted between 0 and 1 second; when DIP 8 has been switched on, the time can
be adjusted between 0 and 30 seconds.

- Switch DIP 4 to ‘off’. (Keep DIP 8 in the position selected.)

5.2.5 Adjusting the switching point of the pressure switch

The pressure switch is preset to a switching point of 5.5 bar. If the pressure falls below

5.5 bar, the system issues a warning with a High at Output D02 and the LED D01 lights
up.

If you require a different switching point, e.g. because your working pressure is only 4
bar, then refer to Chapter 6.3 on adjusting the pressure monitors.

6.1.3 General discrition

Figure 4: Block diagram of the receiver

A supply voltage of 12 – 24 VDC is required to operate the radio receiver. The
connection is established using Cage Clamp® connectors. An external magnetic
antenna for the frequency range of 868 MHz is required to receive the radio telegrams.

The radio receiver is based on the EnOcean radio receiver RCM 121, whose received
data is processed with a downstream microcontroller.

The program in the microcontroller can be divided into the learning mode and the
operating mode.

Learning mode

In the learning mode (activated by DIP 1 ON/OFF), the ID of a detected EnOcean
telegrams*1 is stored in the receiver and the learning mode is automatically closed. If no
valid telegram of a transmitter is received in the learning mode, this is signalled as a
faulty status after 15 s. Alternatively, the transmitter ID can be taught manually by
actuating the DIP switches 6 and 7 (simultaneously).

The adjustment of the monitoring time and the limit value is done by specifying default
values or adjustments with the potentiometer based on a diagram. The diagrams and the
DIP switches are described in the following chapters.

Operating mode

In the operating mode, the receiver monitors the incoming signals of the transmitter with
the watchdog function. The watchdog LED (WD) indicates each incoming telegram of
the taught transmitter by blinking briefly. When the watchdog time set is exceeded, the
WD LED signals an error by staying lit continuously; the WD output switches to the LOW
status.

The LEDs and Outputs DO1 and DO2 directly indicate the status of the two-channel
sensor.

Assembly and Operating Manual

Radio - Pressure - Monitoring RSS R1; RSS P1

date printed: 04.12.200616

The level control monitors the current battery status for an adjustable limit value with
each telegram. When the limit value is fallen short of, the output switches to the LOW
status and the LED is OFF.

The signal strength of incoming telegrams is indicated by blinking codes of the SI LED;
this allows an optimum radio connection to be established already during
commissioning.

6.1.4 Function description devilery condition

After first switching on the voltage supply, the receiver module is in the “INACTIVE”
mode. For the commissioning, the ID of a transmitter needs to be “LEARNING”.

Note

A transmission needs to be activated at the transmitter during the
“Learning phase”. During the learning phase, telegrams from EnOcean
sensors are evaluated on STM basis. . The transmitter with the largest
signal strength is trained.

- None or only a few transmissions of other transmitters should therefore take

place in the reception range of the module to prevent faulty teaching.

6.1.5 Status definition

Status Description

INACTIVE During commissioning, the switching actuator signals a missing assignment (status: inactive)

to the sensor by a blinking watchdog LED (2Hz).

No ID of a sensor has been “learned" yet.

The “inactive” status can be restored by switching on the DIP switch “Delete ID” if no ID has
been learned within the 15-second learning time following actuation.

LEARNING In the learning mode, the receiving range is reduced to approx. 5 m (if DIP 5 = OFF) to

exclude the learning of other receivers as much as possible.

To teach a new radio sensor, the “learn switch” (DIP 1) must be actuated on the receiver. The
learning status is signalled by a slow (0.5 Hz) blinking watchdog LED. The DIP switch should
be reset immediately.

After a telegram has been received from a transmitter, its ID is stored in the receiver, safe
from power failures, and the learning mode is subsequently exited.

In the learning mode, each received (detected) signal of any ID is indicated on the SI LED.
The signal strength of a telegram is indicated until the next telegram is received.

If no new sensor is learned within 15 seconds, the switching actuator returns to the “active” or
“inactive” status.

ACTIVE In the “active” status, the switching actuator monitors all IDs received and compares them with

the ID learned. If the sensor is detected as "assigned", the data bytes received (Data_Byte
0…3) are processed and ouput.

In the operating status “active”, only signals from taught transmitters are indicated on the SI
and WD LED.

System monitoring
/ WATCHDOG

The system check is only switched on in the "active" state. A timer (watchdog abbrev. WD) is
used to monitor whether new data telegrams of the taught sensor have been received within
the system time set. The system time can be adjusted with the system check potentiometer or
the DIP switch.

If the time between two telegrams is greater than the monitoring time, the system LED signals
this fact with a continuous light. The associated output of the system monitoring (output WD)
switches to the LOW status. The status outputs of the sensor maintain the last status.

The output behaviour with addressed system monitoring is non-saving.
When the WD is addressed, the last value of the signal strength is not saved (SI LED); the

current signal strength of the taught sensor continues to be evaluated.

6.1.8 Delete transmitter ID

To learn a new transmitter, the DIP 1 must be momentarily switched to “ON”
(assignment function). Any previously learned transmitter will be deleted and can not be
learned for approx. 30 minutes thereafter (see list of deleted transmitters). For further
behaviour, see “Status definition / LEARNING”

When actuating DIP 1, the ID of the transmitter last learned is stored in a list comprising
a maximum of 10 entries “List of deleted transmitters”. These IDs are stored in the RAM
for up to 30 minutes. The purpose of this is to prevent repeated learning for up to 30
minutes after an incorrect learning followed by deletion.

The “list of deleted transmitters” is reset (i.e. deleted) either by switching off the supply
voltage or if no other transmitters have been deleted for 30 minutes (retriggerable timer).

6.1.9 Signalling of the signal distance or the signal strength

In the as-delivered condition (DIP 2 = “OFF”), the signal distance of the useful signal and
the noise signal is displayed by the blinking SI LED. The ‘noise level’ is measured every
20 ms (watchdog time 0..1 s), or approx. every t = (adjusted watchdog time / 64
measurements) (watchdog time 0..35 s). The average determination for the noise signal
is carried out once a new telegram is available.

6.1.10 Setting the limit value for battery monitoring

The current potentiometer value is stored
when switching on DIP switch 3. During the
setup mode (DIP 3 ON), the LED responds
directly to a changing potentiometer value.

Hint on setting the limit value to approx. 5%
below the current battery level:

- Turn potentiometer until the LED

extinguishes.

- Then turn back by 1 turn (LED lights up

again).

- Set DIP 3 to OFF.

A 3-step hysteresis (approx. 1 %) ensures
a steady function of the indicator in the limit
value range.

If the DIP switch is switched back
without the POTI value having changed
outside of its ‘oscillation range’, no new
value is accepted as system time or
limit value (to avoid faulty operations).

6.1.11 Teaching the limit value (teching threshold)

Accept analog value currently sent

DIP6: The current value of the analog value minus the set hysteresis of 3% is accepted
as limit value for battery monitoring.

Analog value currently sent – 0.5V

DIP7:The current value of the analog value minus 0.5 V is accepted as limit value for
the battery monitoring.

6.1.12 Setting the watchdog time

DIP4: The current POTI value is saved.
During the setup mode (DIP 4 moved), the
LED responds directly to a changing POTI
value (and DIP 8 setting) by changing the
blinking frequency.

The setting occurs using the “System time
setting” characteristic curve. System time =
f (DIP8 and POTI value). The acceptance
occurs only when DIP 4 is switched back.

If the DIP switch is switched back without
the POTI value having changed outside of
its ‘oscillation range’, no new value is
accepted as system time or limit value (to
avoid faulty operations).

6.1.13 Function of the DIP 5 Extension of the reception range during the learning
procedure

By switching on DIP 5, the range reduction to 5 m in learning mode can be switched off,
i.e. the full reception range of the receiver is then used for learning, e.g. in order to learn
more remote transmitters with a good signal strength.

All incoming EnOcean telegrams are (internally) transferred via the serial
interface. The response time of the receiver can thereby be permanently
reduced. (special function of the RCM121DB is not used during this)

It is therefore imperative to switch the DIP 5 back to OFF after the
learning!

6.1.14 Manual setting of the transmitter ID (programming)

By simultaneously activating DIP6 and DIP7, the switching actuator is placed in the
programming mode.

While setting the first ID byte (ID0), the LC LED (incl. output) blinks for 10 s with 0.5 Hz.
The LC LED then lights for 2 s to accept the DIP combination.

Assembly and Operating Manual

Radio - Pressure - Monitoring RSS R1; RSS P1

date printed: 04.12.200620

The input of the ID bytes 1, 2 and 3 is done in the same manner, whereby at the end
(accepting ID3) the LC LED lights for 10 s to have sufficient time to set the output DIP
combination.

Observe the sequence of ID0... ID3 while teaching.

Example ID

00 | 00| 09 | 88 = 00000000 | 00000000 | 00001001 | 10001000

ID3 ID2 ID1 ID0

6.1.15 Monitoring the DIP switches

To avoid faulty operation of the DIP switches, they are monitored per software and faulty
settings are signalled. Faulty settings are indicated by 2 Hz blinking of the limit value
LED (LC). The limit value output also signals this fact at 2 Hz intervals.

Operation

The RSS P1 transmitter module does not contain any controls. Every 10 seconds, it
transmits a signal independently. Furthermore, it transmits a signal if the status of the
input changes.

6.3 Incorporated pressure switch - Adjusting the switching point

The incorporated pressure switch must be adjusted according to your working pressure:

- By turning clockwise, the switching point is adjusted to a point with a higher level of

pressure.

- By turning counterclockwise, the switching point is adjusted to a point with a lower

level of pressure.

- If the pressure is higher than the switching point set at the presure switch, then the

LED D02 does not light up à Securely clamped.

The output behaves the same: Low if the pressure is o.k.; High if the pressure is too
low.

- If the pressure in the chuck is too low (lower than the switching point set at the

pressure switch, then LED D02 lights up. à Pressure warning or chuck open.

Important:

If the red LED WD at the radio receiver lights up for longer than 0.2 seconds,
the radio contact is interrupted. You must stop the adjustment process and
check what is disrupting the radio contact.

6.3.1 Adjusting a defined minimum pressure, Method 1

- Set the preferred minimum pressure at the maintenance unit. The system will then

issue a warning (LED D02 lights up, Output is set if this pressure is not met in the
process).

- If the LED D02 is not off, then the Allen screw on the pressure switch must be turned

counterclockwise until the LED D02 is extinguished.

- Now slowly turn the Allen screw at the pressure switch clockwise until the LED D02

lights up again.

- You can now increase the pressure at the maintenance unit back to its normal working

pressure.

- Check the function: If you then close the chuck with your working pressure, the LED

D02 must extinguish after a short while. If you then open the chuck again, the LED
D02 must light up again after a short while. If you adjust the pressure to a value less
than your minimum pressure and then close the chuck, the LED D02 may no longer
extinguish, even for a closed chuck.

date printed: 04.12.200622

6.3.2 Adjusting a minimum pressure not exactly defined, Method 2

- Adjust the normal working pressure and close the chuck.

- If the LED D02 is not off, then the Allen screw on the pressure switch must be turned

counterclockwise until the LED D02 is extinguished.

- Now slowly turn the Allen screw at the pressure switch clockwise until the LED D02

lights up again.

- You can now turn the Allen screw at the pressure switch counterclockwise until the

LED is extinguished, and then turn a little more.

Unfortunately, the relationship of turns of the Allen screw is not linear to
the change of the switching point in bar.

Basically, a change of the switching pressure of approx. 0.9 bar per ¼
counterclockwise turn can arise for 6 bar output pressure.

6.3.3 Check the function

(1) If you then close the chuck with your working pressure, the LED D02 must light up after

a short while.

(2) If you then open the chuck again, the LED D02 must extinguish again after a short

while.

(3) If you adjust the pressure to a value less than your minimum pressure and then close

the chuck, the LED D02 may no longer light up, even for a closed chuck.

- For reasons of safety, you may now have to fasten the screw at the pressure switch

using glue and then tighten the screw the cover over the pressure switch to seal the
chuck.

- To adjust the switching pressure subsequently, you only have to remove the middle

screw from the cover. Through the resulting hole, you can now adjust the screw at the
pressure switch using the appropriate Allen wrench.

- The locking screw in the cover must be pressure tight; otherwise, cooling lubricant may

penetrate the system.

7 Maintenance and Care

- The system is completely maintenance-free.

- Only the life of the transmitter is limited by the built-in battery.

- Life when transmitting once per 10 seconds: <. 7 years
