    • A control device for converting a control movement along a control path into a control signal has the control path corresponding to different control stages or control types. The control device has two measuring tracks with a linearly changing resistance associated with each track. In one embodiment, these measuring tracks are positioned concentric to each other in a semicircle. A voltage U, which is tapped via two opposite interconnected sliders, is applied to both measuring tracks at a junction point while the other junction point is connected to ground. If the detected values of the tapped voltages deviate from a corresponding stored value or pairs of values, there must be a fault, due to, for example a broken slider. This makes it possible to perform a test for determining the fault or a malfunctioning control device.
    • 用于将沿着控制路径的控制运动转换为控制信号的控制装置具有对应于不同控制级或控制类型的控制路径。 控制装置具有两个具有与每个轨道相关联的线性变化的电阻的测量轨迹。 在一个实施例中,这些测量轨道以半圆形彼此同心定位。 通过两个相互相互连接的滑块敲击的电压U被施加到连接点处的两个测量轨道,而另一个连接点连接到地面。 如果检测到的抽头电压的值偏离相应的存储值或值对,则由于例如断开的滑块而必须存在故障。 这使得可以执行用于确定故障或故障控制装置的测试。
