| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide relay fault detection.SOLUTION: A relay fault detection and correction system includes a signal detector structured to measure primary and secondary signals, and generates a fault output signal if the signals appear to be unterminated due to a relay not connecting the signals to loads. A cycle circuit is structured to cause a relay controller to cycle a potentially under-performing relay after the signal detector generates the fault output.
【課題】 リレーの故障を検出する。【解決手段】 リレー故障検出システム及び直しシステムは、１次及び２次信号を測定するように構成される信号検出器を含み、リレーが信号を負荷に接続しないために信号が終端しなくなると故障出力信号を生成する。信号検出器が故障出力を生成した後、循環回路によりリレー制御器が潜在的に機能低下しているリレーを何回も循環するように構成される。【選択図】図２ |
