Claims

[Claims for Utility Model Registration] In a lap circuit that switches a controlled device between a first control mode and a second control mode without stopping, a lap circuit that is turned on when switching to the first control mode; a changeover switch including a first on contact and a second on contact that is turned on when switching to a second control mode; and a changeover switch that is turned on at the start of the first control mode and the second control mode, respectively; An on contact for starting a first control mode, an on contact for starting a second control mode, and an off contact for ending the first control mode that is turned off at the end of the first control mode and the second control mode, respectively. and an off contact for ending the second control mode;
The first on-contact is on and the on-contact for starting the first control mode is on, or the second on-contact is on and the on-contact for starting the second control mode is on. and a relay that operates under a logical sum condition and controls a controlled device by a contact output, and the self-holding contact of the relay is connected to the first contact and the off contact for ending the first control mode. connected to a self-holding power source through a parallel circuit in which a series circuit and a series circuit of the second contact and an off contact for ending the second control mode are connected in parallel with each other, the off contact for ending the first control mode; and the second control mode termination OFF contact are connected to form a self-holding loop of the relay during a control mode switching transient state.
