The reference voltage to the UFL is supplied by Zener diode Z1. The UFL operational threshold for standard 50 Hz, 60 Hz, and 400 Hz KCR 760 regulators are given above. The operation of the various components comprising the UFL assembly is described in the paragraphs that follow. The voltage from the sensing transformer is recti ed by diodes D19 and D21, and the recti ed signal is applied to a Schmidt trigger consisting of operational ampli er IC2A, resistors R47 through R51, and capacitor C29. A 24 Vdc peak-to-peak square wave is generated at the output of IC2A at double the frequency of the sensing voltage. The 24 Vdc square wave from the Schmidt trigger is fed to the rst stage of a two-stage monostable multivibrator IC1 and associated parts, where it is decreased to a 5 Vdc peak-to-peak square wave at double the frequency of the sensing voltage. The 5 Vdc square wave is applied to the second stage of the monostable multivibrator. The monostable multivibrator output pulse is uniform in amplitude and duration for each input pulse. Thus, the average voltage level of the collective pulses at the output of the monostable multivibrator is directly proportional to the frequency of the pulses. The monostable multivibrator output is fed into a four-pole Butterworth low pass lter comprised of operational ampli er IC2B and IC2C, resistors R60 through R66, and capacitors C13 through C18. This ltering circuit does the actual averaging of the collective pulses from the monostable multivibrator. Ampli er gain is set at level where its output equals the Zener reference at rated 60 Hz or 400 Hz operation by resistors R65, R66, and capacitor C16. When operated at rated frequency of 50 Hz, the circuit is set for 50 Hz operation by removing jumper J1. This action adds R57 to the circuit. Diode D12 and integrated circuit IC2D form a voltage clamping circuit. If the voltage from the Butterworth lter is equal to that of the Zener reference, the UFL output to the error detector will be the same as the Zener reference and the UFL will have no effect on regulator operation. However, when the voltage from the lter decreases as occurs during underspeed operation of the generator, the reference voltage applied to the error detector is less than the Zener reference. This action will cause the error detector differential signal to proportionally increase in a manner that results in a proportionally later turn-on signal to the regulator output SCRs. The regulator then decreases excitation and a lowering of generator output voltage occurs.
