  • Page 4: Functional Description

    VEK S4 Functional Description The VEK S4 traffic detector is a dual system for the inductive detection of vehicles. Information about the speed, length and class of a vehicle can be provided using the measuring system (two loop principle) and its 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 S4 detector has two classification modules for the vehicle recording. These can be parameterised independently from each other. 1.3.1...

    Manual VEK S4 1.3.4 Tailgating If a vehicle is driving to close to the car in front a dummy vehicle (Other, l = 4.5 m, v= last vehicle) is reported with the vehicle speed of the car in front. Note: A correct detection of driving direction is not guaranteed for all tailgating situations.

  • 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 S4 uses the device address to choose one of the frequency range above. Please check the real frequency, because it can differ from the nominal frequency.
  • Page 9 Manual VEK S4 • Amplitude factor The loss of sensitivity due to abnormal loop dimensions, long loop lines or road surface reinforcements is largely compensated for using the amplitude factor. Automatic evaluation of this factor is also available. • Length adjustment The measured vehicle length is corrected with the length adjustment.

  • Page 11: Rs485 Interface

    The VEK S4 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 S4 behaves like two separately addressable VEK S3 units. Mixed operation of VEK S3 and VEK S4 on a common bus is not recommended.

    Manual VEK S4 Starting up 1. Installation – The installation rail must be grounded. 5 Case and 7.5 PE connection 2. Address – The detector address is set to 48 at the factory using the address offset. All detectors which will be operated on a common interface must be set to different addresses before the commissioning.
  • Page 13 Manual VEK S4 11. Length adjustment – The displayed and actual lengths of a known vehicle must be compared and adjusted using the length adjustment. The adjustment of the speed and length measurements should be made with reference to average values obtained from several measuring cycles.

    Manual VEK S4 4.3 Factory settings To restore the factory default parameters, proceed as follows: 1) Press button 6x briefly until shows on the LEDs. 2) Hold button down After one second all LEDs flash rapidly. After two seconds the LEDs go out.

  • Page 16: Synchronisation Display

    Manual VEK S4 4.4 Synchronisation display Correct function of the synchronization of multiple detectors is indicated by the scrolling effect of the LEDs in an 8s rhythm. As the device address increases from left to right, the scrolling LEDs also run from left to right for all synchronized detectors.

    Manual VEK S4 Safety instructions and warnings • The device may be used only for the purpose intended by the manufacturer. • This manual must be kept in an accessible place and handed out to each user. • Improper modifications and use of replacement parts and add-on equipment not purchased or recommended by the manufacturer may cause fire, electrical shock and injury.

  • Page 25: 10 4-Channel Functions

    VEK S4 10 4-channel functions The VEK S4 detector can also be used for presence detection with flexible direction recognition due to its integrated 4-channel functions (4Ch). The parameters for use as a presence detector are explained in this chapter.

A zero setting means infinite waiting time.

  • Page 28: Direction Recognition (4Ch)

    VEK S4 10.5 Direction recognition (4Ch) In addition to the simple direction recognition present in the classification modules, the VEK S4 detector has two parameterisable logic modules for the direction-dependent recording of vehicles. Complex evaluation 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.

The evaluation of the direction signal is performed in the same manner in the reverse direction of travel as well for Loops 3 and 4 or other loop combinations.

This means it is non-critical whether Loop 1 is placed in the passing lane or in the maneuvering area.
