Page 3: General Features
AVR BL4-U is connected with the main stator windings and the exciter field windings to provide closed loop control of the output voltage. In addition to being powered from the main stator, AVR BL4-U also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, AVR BL4-U... -

Page 5: Adjustments
If no hand potentiometer is required terminals Ext and Pot will be fitted with a shorting link. STABILITY ADJUSTMENT The AVR BL4-U includes stability or damping circuit to provide good steady state and transient performance of the alternator. The correct setting can be found by running the alternator at no load and slowly turning the stability ST clockwise until the alternator voltage starts to become unstable. - Page 6 UNDER FREQUENCY KNEE ADJUSTMENT AVR BL4-U incorporates an underspeed protection circuit (UF) which gives a volts/Hz characteristic when the alternator speed falls below a presettable threshold known as the "knee" point. The UF knee adjustment is preset at factory at the 47Hz on a 50Hz system or 57Hz on a 60Hz system.
