  • Page 4: Functional Description

    VEK S4C Functional Description The VEK S4C traffic detector is a dual system for inductive detection of vehicles. Information about speed, length and class of a vehicle can be provided using the measuring system (two loop principle) and its evaluation. The data determined in this way are assembled in a data protocol and provided to a higher level system (host computer) for further evaluation.

  • Page 5: Vehicle Detection

    Longer calibration times are caused by frequency instabilities; their causes must be determined and remedied. 1.3 Classification of vehicles The VEK S4C detector has two classification modules for vehicle detection. These can be parameterised independently from each other. 1.3.1 Vehicle data...

  • Page 6: Possible Outputs

    Manual VEK S4C 1.3.3 Classification in the case of loop fault Speed and length measurement and classification is not possible in the case of a defective loop. A dummy vehicle (class = Other, l = 40 dm, v = 0 km/h) is reported for every vehicle which crosses the second intact loop.

  • Page 7: Synchronisation

    Manual VEK S4C 1.6 Synchronisation To prevent mutual interference between induction loops of multiple detectors, the latter can be synchronized with each other using a connection in the front-side ribbon cable. All detectors connected via the synchronous line process the multiplexing sequence synchronously. Only loops which are active in the same time window can affect each other.

  • Page 8: Settings

    For long loop supply lines it is recommended to use band 2..4 for frequency setting. If automatic frequency setting is activated, the VEK S4C uses the device address to choose one of the frequency ranges above. Please check the real frequency, because it can differ from the nominal frequency.

  • Page 9: Classification

    Automatic calculation of this factor is also available. By setting ‘0’ for the amplitude factor the VEK S4C begins to evaluate the next 50 cars in the length range of 350...450 cm. If the evaluation process is finished the VEK S4C stores the new adjustment factor in the EEPROM.

  • Page 10: Output Modes

    Manual VEK S4C Vehicle counter • Each classification module has a 16-bit counter per vehicle class and travel direction which can be invoked via the RS485 interface. It must be noted that the counters roll over at 65535 (2 ) and restart from 0. It is not recommended to reset the counters otherwise vehicles can be lost at the time of the reset.

  • Page 11: Simulation Of Output Signals

    The VEK S4C is downwards compatible with the interface protocols defined for the VEK S3. The protocols based on the TLS defined in the VEK S3 are also supported. In these cases, one VEK S4C behaves like two separately addressable VEK S3 units. Mixed operation of VEK S3 and VEK S4C on a common bus is not recommended.

  • Page 12: Initial Start-Up

    Manual VEK S4C Initial Start-up 1. Installation – The 19” rack must be grounded and PE contact on the DIN connector must connected to Ground. 7.10 PE connection  2. Address – The detector address is set to 48 at the factory using the software address offset. All detectors which will be operated on a common interface must be set to different addresses before initial start-up.

  • Page 15: Device Address

    Manual VEK S4C 4.4 Device address The device address results from the hardware device address set using the DIP switches or DIN connector and the software settable address offset. Device address = Hardware device address + Address offset For downward compatibility to traffic detector VEK S3 the step size for the hardware device address is 2.

    Manual VEK S4C 4.6 Synchronisation display Correct function of the synchronisation for multiple detectors is indicated by the scrolling effect of the LEDs in an 8 s rhythm. As the device address increases from left to right, the scrolling LEDs also run from left to right for all synchronised detectors.

  • Page 29: Hysteresis Drop (4Ch)

    Manual VEK S4C 10.3 Hysteresis drop (4Ch) In order to avoid an intermediate loss of the occupied signal for vehicles with a high undercarriage such as articulated buses, trams, trucks with trailers etc, it is possible to modify the switching hysteresis. An interruption-free detection of critical vehicles is then also possible for low sensitivity setting.

  • Page 30: Direction Recognition (4Ch)

    VEK S4C 10.5 Direction recognition (4Ch) In addition to the simple direction recognition present in the classification modules, the VEK S4C detector has two parameterisable logic modules for the direction-dependent recording of vehicles. Complex evalua- tion algorithms using double loops are integrated in the detector. The direction logic generates logical output signals which can be output via a hardware output or via an interface depending on the setting.
