Abstract

PURPOSE: To secure the supervision for the erroneous selection control regarding the unit operation by installing the circuit which detects the miscarriage of the unit selection control conditions when the unit selection control command is produced, thus reducing the load of the trainees.
CONSTITUTION: Short-circuit preventing resistance 1 is connected in series to unit selection control switch 2 which controls the units, and then the contact showing the selection conditions for the units is connected in series to relay 4 which detects the formation of the unit selection control conditions when switch 2 is operated. Thus the operation command is given to the unit to be controlled. Furthermore, contact 5 which breaks at the operation time of relay 4 and erroneous selection control detection circuit 6 are connected newly in parallel to the node between relay 4 and switch 2 of the detection circuit. Thus circuit 6 gives the supervision to the miscarriage of the unit selection control conditions for the circuit which generates the operation command. And in the case of miscarriage, the operation is inhibited to lessen the load for the trainees.
