PURPOSE:To ensure both safety and quick responsiveness, by switching automatically to set the responsiveness-priority only in case the specific state quantity of a device to be controlled becomes larger or smaller than the prescribed value. CONSTITUTION:Two integration element I circuits 31 and 32 are provided to increase the gain of the 2nd circuit 32 much more than the gain of the 1st circuit 31. When the revolving speed is higher than the prescribed value, a switch 11 is automatically switched so as to supply a signal X2 although a signal X10 is usually supplied. As a result, the setting is automatically to the responsiveness-priority when the revolving speed exceeds the prescribed value. |
