DEFINITION

Classification: 303/122

With failure responsive means:

(under subclass 121) Speed control provided with means for detecting faulty operation of a speed control regulator and means for overriding a speed condition regulator.

(1) Note. This subclass includes systems which cycle the speed responsive control means in response to a simulated speed condition to thereby check for the proper operation of the speed responsive means and also includes means for monitoring various components of a speed responsive control means to detect any failure thereof.
