Method and device for blocking the traction of a stationary rail vehicle

摘要

The method involves arranging a drive signal latch circuit (9) in a control signal path (10) by a traction lock (1). A control unit (6) is provided for generating traction lock request signal (3) and a test request signal (13) received by a unit (2) and by a signal path (5). A portion of the control signal path is read by the control unit by a read-back channel (23) of the signal state located between a control signal cut-off circuit and a drive unit (22). An independent claim is included for a device for locking traction of a stationary rail vehicle.
