Basic safety notes 6 02.02_preliminary|Id. Nr. 8705401 |en 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 2 2.1 2.2

Max. 0 50 Weight [kg] 0.16 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, 6.2 6.3
Technical data 02.02_preliminary|Id. Nr. 8705401 |en 15 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 16 02.02_preliminary|Id. Nr. 8705401 |en 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.

Start‐up 18 02.02_preliminary|Id. Nr. 8705401 |en 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 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 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. 8 8.1 8.2
Start‐up 02.02_preliminary|Id. Nr. 8705401 |en 19 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!). 8.3 8.4

Functional description 22 02.02_preliminary|Id. Nr. 8705401 |en General discription 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® con‐nectors. 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 micro‐controller. The program in the microcontroller can be divided into the learn‐ing mode and the operating mode. Learning mode In the learning mode (activated by DIP 1 ON/OFF), the ID of a de‐tected EnOcean telegrams is stored in the receiver and the learn‐ing mode is automatically closed. If no valid telegram of a trans‐mitter is received in the learning mode, this is signaled as a faulty status after 15 s. Alternatively, at Status of “INACTIVE” the trans‐mitter ID can be taught manually by actuating the DIP switches 3 and 4 (simultaneously). 9.1.3
Functional description 02.02_preliminary|Id. Nr. 8705401 |en 23 The adjustment of the monitoring time and the limit value is done by specifying default values or adjustments with the potentiome‐ter based on a diagram. The diagrams and the DIP switches are de‐scribed 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. 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. Function description delivery 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 pre‐vent faulty teaching. 9.1.4
Functional description 24 02.02_preliminary|Id. Nr. 8705401 |en Status definition Status Description INACTIVE During commissioning, the switching actuator signals a missing as‐signment (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 ac‐tuated on the receiver. The learning status is signalled by a slow (0.5 Hz) blinking watchdog LED. The DIP switch should be reset immedi‐ately. 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 re‐ceived and compares them with the ID learned. If the sensor is de‐tected as "assigned", the data bytes received (Data_Byte 0…3) are processed and output. In the operating status “active”, only signals from taught transmit‐ters are indicated on the SI and WD LED. System moni‐toring / WATCHDOG The system check is only switched on in the "active" state. A timer (watchdog abbrev. WD) is used to monitor whether new data tele‐grams 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 9.1.5
Functional description 02.02_preliminary|Id. Nr. 8705401 |en 25 Status Description 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. Time response The time lag between measurable telegrams must be at least 50 ms. For small grippers, the time between 'Gripper open' and 'Gripper closed' is considerably shorter. However, it is possible here to set a sensor for 'Gripper open' and the other sensor for 'Gripper closed'. As the gripper usually either opens or grips a part, but very rarely closes completely, the system can be programmed as with cable‐based sensors. If the gripper now closes completely due to a missing component, the gripper closed message comes ten seconds late.

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). Signaling the distance between signals 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 measure‐ments) (watchdog time 0..35 s). The average determination for the noise signal is carried out once a new telegram is available.

Functional description 28 02.02_preliminary|Id. Nr. 8705401 |en Setting the limit value for battery monitoring Limit value setting The current potentiometer value is stored when switching on DIP switch 3 at status of “ACTIVE” and “Watchdog”. During the setup mode (DIP 3 ON), the LED responds directly to a changing potenti‐ometer value. Hint on setting the limit value to approx. 5% below the current battery level: 1 Turn potentiometer until the LED extinguishes. 2 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). Setting the output behaviour Functional change of the output signal D01 Output D01 will not be received as at radio transmitter, but is “NOT D02”. Teaching the limit value (teaching threshold) Analog value currently sent – 0.5V The current value of the analog value minus 0.5 V is accepted as limit value for the battery monitoring. 9.1.10 9.1.11 DIP6 = ON: 9.1.12 DIP7:
Functional description 02.02_preliminary|Id. Nr. 8705401 |en 29 Setting the watchdog time Setting the watchdog time The POTI value is saved by turning on of the DIP switch 4 at status “ACTIVE” and “WATCHDOG”. During the set‐up 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 oc‐curs 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). 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 trans‐mitters with a good signal strength. NOTE All incoming EnOcean telegrams are (internally) transferred via the serial inter‐face. 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! 9.1.13 9.1.14
Functional description 30 02.02_preliminary|Id. Nr. 8705401 |en Manual setting of transmitter ID (programming) By simultaneously activating DIP3 and DIP4 at status “INACTIVE”, 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. 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. Example ID: 00 | 00| 09 | 88 = 00000000 | 00000000 | 00001001 | 10001000 ID3 ID2 ID1 ID0 DIP 1|2|3|4|5|6|7|8 NOTE Observe the sequence of ID0... ID3 while teaching. 9.1.15

Two reed switches are integrated instead, which can be operated via screw fastened magnetic brackets. Unscrew the magnetic bracket of its present position. Screw in the magnetic bracket into the desired position again. If the magnetic bracket should not be screwed in somewhere, this will correspond to the „normal mode“. 9.1.16 9.1.17 9.2 9.2.1
Functional description 32 02.02_preliminary|Id. Nr. 8705401 |en The transmitter module is not equipped with control elements. It independently sends a signal every 10 seconds. Anymore if the state of the input is changed, it immediately sends a signal. NOTICE If the red LED WD lights up longer than 0,2 seconds, the radio contact is disturbed. The adjustment work must be interrupted and it should be checked what disturbs the radio contact. Operating mode Storage mode: This is the delivery state. In this mode, the transmitter module re‐acts to changes in the two sensor inputs with a wireless telegram, but doesn't transmit any presence signal. This mode is used for po‐sitioning the transmitter. The advantage here is the low energy consumption. The life span of the battery is hardly shortened dur‐ing positioning. Test mode: This mode places great load on the battery. It should only be used for a short a time as possible! The mode is used for adjusting the two sensors and for testing the transmitter. LED ‐ Display DesignationLED Meaning D01 light luminous The sensor 1 is actuated. The contact of the sensor is closed. D02 light luminous The sensor 2 is actuated.

Maintenance and care 02.02_preliminary|Id. Nr. 8705401 |en 33 Maintenance and care The system is maintenance‐free. Only the life span of the transmitter is limited by the installed bat‐tery ( 6, Page 13) and Link Batterie tauschen. 10
Information FCC certification 34 02.02_preliminary|Id. Nr. 8705401 |en Information FCC certification The RSS‐T2‐US/CA is used at grippers. Incorrectly gripping the workpiece may cause the gripped work‐piece to loosen itself out of the gripper fingers during movement and to move uncontrollably. As a result there may be significant material damage and/or serious personal injury. To detect if the gripper fingers are positioned correctly, up to 2 reed switches can be attached to the gripper and in this way 2 po‐sitions can be monitored. If the correct position is reached, the signal at the sensor is changed which results in a radio signal. To ensure there is a radio contact, cyclical sending is required eve‐ry 10 seconds.
