The following safety symbols are used to draw the reader's attention to the safety instructions included in this manual. Danger There is a threat to life or health unless the following safety measures are observed.
  • Page 6 1.4 Delivery state The product is supplied with a defined hardware and software configuration. Any changes in excess of the docu- mented options are not permitted and lead to liability exclusion.
  • Page 7 2. INTRODUCTION 2.1 SCS200 intelligent power distribution Intelligent and complex systems and the electrification of loads currently play a decisive role in the development of on-board electrical systems. The SCS200 is the right answer to these requirements. The intelligent power distribution system enables decentral- ized control and monitoring of loads via the CAN bus.
  • Page 8 Figure 1 Example of the SCS200 in a vehicle The SCS200 is available in both SAEJ1939 and CANopen compatible versions. The module allows uncomplicated and quick system extensions or complete vehicle or machinery modernization. Figure 1 shows an example of how the SCS200 can be integrated in the on-board electrical system.

MOUNTING METHOD AND CONNECTION 3.1 General information Please ensure sufficient space for the mating plugs of the output terminals (Figure 2) for the relay version, this must also be observed for removing the cover. Figure 2: Required space for plugging in the Tyco mating plug 3.2 Mounting the module The device must be firmly mounted before connecting the cables.
  • Page 10 each rotated by 90°. Please take this into account when laying your cables. Please use M6 fastening screws for installation (tightening torque max. 6 Nm). The mounting material is not included in the scope of delivery. In addition, the semiconductor versions can be mounted in any position, while the relay version must not be mounted with the cover facing downwards to prevent the components from loosening.

These are the semiconductor version and the relay version, which are described in more detail below. Furthermore, each main variant is available in different versions for different voltage ratings. All versions of the SCS200 feature the same housing footprint to allow ease of replacement.

  • Page 17 Please observe performance limits described in the data sheet when using the relays. Operation in excess of these values is not allowed. There is a risk of damaging the relays and resulting burns when touching. When mounting the relays, the max. allowed number of plug-in operations of the terminals must not be exceeded.
  • Page 18 4.3 Analogue inputs The SCS200 provides up to 6 analogue inputs or sensor inputs. The specific number depends on the version of the SCS200 and if some of the inputs are used for PMA. For details, please refer to the pin assignment on previous pages.
  • Page 19 5. SOFTWARE AND DIAGNOSTIC FUNCTIONS The SCS200 is a CAN-controlled power distribution board providing comprehensive diagnostic functions as well as current and voltage monitoring. This product is a client module that is controlled by a superordinate control unit or ECU via the CAN bus. The SCS200 receives commands for switching the load outputs in the form of CAN frames and provides diagnostic data and measured values in the event of a change or on request.
  • Page 20 The SCS200 can be configured without a special programming environment or associated software. Settings can be made using predefined CAN frames that are sent to the device via the bus. The configuration or initialisation of the module can therefore also be carried out directly by a superordinate control unit or ECU during vehicle production. A connection to a PC can also be established via a CAN-to-USB adapter.

  • Page 24 Semiconductor self-protection The SCS200 uses intelligent semiconductors with integrated self-protection. Due to that it my happen in some cases, the SCS200 detects an open load instead of an overcurrent. This can happen with very high short-circuit currents, as the used semiconductors have an integrated self-protection. Depending on the level of the short-circuit current, the switch-off by the self-protection may be faster than the regular overcurrent detection, in which case the µC detects an open load accordingly, as it still assumes the switching state ON.
  • Page 25 The SCS200 will still be able to communicate if the voltage is lower than the thresholds mentioned above. If the voltage is decreased further the SCS200 will lose the ability to communicate. The thresh- old depends on tolerances as well as environment and age. The SCS200 will still be able to communicate if the voltage is higher than the thresholds mentioned above.
  • Page 26 5.3.2 Voltage measuring The SCS200 provides current measured values for the supply voltage and the voltage applied to the load outputs via the CAN bus. These values can also be analysed to implement load management. Measuring accuracy of voltage measurement @ U ±...
  • Page 27 5.4 Physical module addressing (PMA) The address of the CAN node can be changed in two ways. The option to do this via CAN message is explained in chapter 6.3.1.1. In addition to this method, a physical address assignment is possible for the SCS200. In this case, the analog inputs 1-3 of the module are used as standard to define the node address of the SCS200.
  • Page 28 If PMA is used, analog inputs 1-3 are not available as standard analog inputs. The voltage values are not sent via a CAN message; the inputs are only used to assign the address offset. Analog inputs 4-6 are still available as analog inputs by default. If PMA is active, the potential at inputs 1-3 is checked each time the module is started Physical module addressing can be deactivated at any time via a CAN configuration message.
  • Page 29 Also, for trip 2 the sum of both outputs is used. To deactivate trip 2 for the parallel connection it has to be deactivated for the numerically smaller output. Switch ON and switch OFF delays of the numerically smaller channel are taken over for the pair. Changes for switch ON/OFF delays after the two channels are paired can be done with the specific CAN message für the numerically smaller channel.
  • Page 30 To use the configuration of the CFS (CAN fail-safe), several items have to be configured in a row. Figure 7: CFS configuration sequence Detailed information about these steps can be found in 6.3.1.9 for J1939 and 6.5.2.2 for CANopen. 5.9 Default configuration and factory reset During configuration process or if the module is used in a different setup than before it might be easier to restore either the default configuration or do a factory reset than changing every previously made configuration back.
  • Page 31 The following methods can be used to wake up the device. • Via CAN: In the event of CAN activity – CAN messages not directly addressed to the SCS200 are suitable for waking the device up. Any activity on the bus will wake up the module. •...
  • Page 32 The SCS200 can also be set to deep sleep mode by sending a CAN message. If there are multiple SCS200 on the same CAN it´s possible to set single ones to deep sleep mode by using the specific node ID. Further it´s possible to send all of them to deep sleep with a broadcast message.
  • Page 33 6. CAN COMMUNICATION The CAN communication of the SCS200 is based on the CAN 2.0 specification and supports the SAE J1939 standard as well as CANopen. The product can be integrated into a corresponding CAN system with other standard compo- nents.
