Abstract

PURPOSE: To allow a load limiter to perform smooth automatic tracking by providing a tracking width detector which interrupts the operation of a deviation detector until the deviations of speed regulating signals and load limiting signals are reduced under respective fixed values.
CONSTITUTION: A tracking width detector 15 and a relay 14 are inoperative and a contact point 14b is closed while tracking width is excessive when a switch 11 is closed, then an operation permission relay 12 operates so that the system is automatically controlled if the tracking width is excessive. As the tracking width gradually approach to a set value and when the tracking width detector 15 starts operating, the relay 14 is actuated to open the contact point 14b. Thus with a deviation detector 10 operative, an alarm 13 is actuated when a contact point 10a is closed and ordinary control operation is performed when the contact point 10b is closed.
