Classification: CPC H  B  G | IPC G  H

Claim 20:
21. The control system of claim 20, wherein
the first driven unit includes a contact device and a signal inverter circuit,
the contact device includes a first contact and a second contact which are to be connected to the auxiliary electric circuit,
the second contact is movable between a closed position where the second contact is in contact with the first contact and an open position where the second contact is out of contact with the first contact,
the first driving unit is configured to use the abnormal current flowing through the intermediate electrical path to move the second contact from the closed position to the open position, and
the signal inverter circuit is configured to:
prevent the startup current from being supplied to the auxiliary electric circuit when the second contact assumes the closed position, and
allow the startup current to be supplied to the auxiliary electric circuit when the second contact assumes the open position,
the second driving unit includes a primary winding forming at least part of the second intermediate electrical path,
the second driven unit includes a secondary winding electromagnetically coupled to the primary winding and configured to be connected to the auxiliary electric circuit, and
the control system uses the abnormal current flowing through the primary winding to supply the startup current from the secondary winding to the auxiliary electric circuit.
