Description
き、センサ電圧の振幅は100%の重なり合い度のときに最小になり、この最小のセンサ電圧の大きさは間隔xに依存して決まる。このようにリアクタンスLは可変である(図1)。
− 重なり合い度Gは定義された大きさに保たれ、操作部材Bとセンサループの間の間隔xが変化する(その様子は、たとえば図2に図示されている)、または、
− 間隔xは相対的に一定のままに保たれ、重なり合い度Gが変化する(その様子は、たとえば図3のy変位によって図示されている)。
− 両方の切換メカニズムxおよびyの組み合わせも考えられる(図3)。
要することなく実現することができる。この図面では、1つの位置ごとに1つのセンサユニットではなく、1つの位置ごとに2つのセンサユニットを取り付けて、それぞれの信号を比較することが提案される。矛盾する結果が出たときは、システム全体が確実な状態へ移行するように評価ユニットが切換機能を実行する。そのために、たとえば図9に示す安全センサユニットSSEによって配線板を拡張することができる。
操作部材を第1の位置(たとえば8mm)に移す。このときに第1の直線上の値(たとえば0.2)を記憶しておく。別の切換閾値でも同様の手順を踏む。作動時には、目下交差している直線上の座標値が継続して切換閾値と比較される。図18の例では、操作装置の最新の位置は28mmのところにある。座標の値は0.2であり、第2の切換閾値の座標値(0.8)よりも小さい。このことは、操作部材の最新の位置が領域3にあることを意味している。
あらためて設定しなければならない。
