Digital Control Systems for Rail Traction

Control systems for diesel-electric and diesel-hydraulic locomotive of HEINZMANN and RE are characterised by precise speed governing and stable and reliable operation. Their compact and robustly designed hardware components are adapted to the harsh environmental conditions in locomotives. HEINZMANN locomotive control systems are installed worldwide, in both passenger and freight trains, and have been chosen by leading locomotive manufacturer for retrofitting.

Traction Control

  • Viking Traction Control

    Viking Traction Control

    The Viking Traction Control unit is designed for the railway environment and houses the following main components:

    • Viking Digital Controller ECU
    • Speed switch pcb
    • Protection module
    • Interface circuitry

    The engine protection provided by Viking Traction solutions provides de-rating with respect to measured parameters; this helps to ensure that the locomotive can continue to operate safely even if a fault is detected. As an additional feature Viking traction can interface with remote monitoring; thus, allowing operational problems to be viewed and diagnosed at the depot.

  • Viking Control Panel

    Viking Control Panel

    Viking Traction control panel with a Viking ECU performs the following core functionality:

    • Speed governing
    • Start interlocks
    • Engine auxiliaries control during starting/running/stopping conditions
    • 1st and 2nd stage engine protection
    • Overspeed protection
    • Independent engine shutdown by separate protection module
  • Power Unit

    Power Unit

    Provides regulated 28 VDC, 300 W power supply output for the traction control and monitoring units, derived from a power car supply input. Protects components from power supply surges and transients in accordance with RIA12 requirements Includes a back up battery for short periods of loss of main power.
  • Hydraulic Actuator

    Hydraulic Actuator

    The 2221 is a proportional actuator where the position of the output shaft is proportional to the electrical input signal 0-1 A. This actuator is typically used in medium/high-speed diesel engines in generator systems or locomotives.
  • Viking35

    Viking Control

    The Viking35 is an ECU with a high number of I/Os, suitable for a wide range of complex control and monitoring tasks in ships, locomotives and generators. Viking35 has established itself as the ideal solution on the market for applications involving complex load sharing in particular.

    • User-friendly Viking Vision software or a corresponding hand-held or panel mount device can be used to edit or display control and status parameters in real time.
    • It is combined with hydraulic actuators from REGULATEURS EUROPA.
    • Viking35 also meets the requirements of Marine Classification Societies for EXXI approval with its simple and effective power limiting solution.
