CHANGEOVER CIRCUIT
To provide such a circuit that is capable of solving production efficiency reduction caused by conventionally implementing different kinds of wiring work in accordance with a single alternate operation system in which only one of two pumps is operable and a parallel operation system in which the two pumps are simultaneously operable.SOLUTION: A changeover circuit 1 comprises: a first control circuit 61 which controls opening/closing of a first main contact 33 provided in a first main circuit 11 supplying power to a first motor 4; and a second control circuit 62 which controls opening/closing of a second main contact 43 provided in a second main circuit 12 supplying power to a second motor 5. The changeover circuit also comprises a changeover switch 56 capable of changing over the first control circuit 61 and the second control circuit 62 to a first interlock circuit 63 and a second interlock circuit 64 corresponding to a single alternate operation system, and to a first detour circuit 65 and a second detour circuit 66 corresponding to a parallel operation system.SELECTED DRAWING: Figure 3
【課題】２台のポンプのうち１台しか運転できない単独交互運転方式と、２台のポンプを同時に運転できる並列運転方式とで、従来異なる配線作業を行っていたことによる製作効率の低下を改善できるような回路を提供すること。【解決手段】上記課題を解決するために、本発明に係る切替回路１は、第１電動機４に電力を供給する第１主回路１１に設けられた第１主接点３３の開閉を制御する第１制御回路６１と、第２電動機５に電力を供給する第２主回路１２に設けられた第２主接点４３の開閉を制御する第２制御回路６２とを備え、第１制御回路６１及び第２制御回路６２を、単独交互運転方式に対応した第１インターロック回路６３かつ第２インターロック回路６４と、並列運転方式に対応した第１迂回回路６５かつ第２迂回回路６６とに切り替えることができる切替スイッチ５６を設けたことを特徴とする。【選択図】図３
