SR 4 GENERATOR SYSTEMS OPERATION POWER SUPPLY FOR REGULATOR MODULE A1 For SR 4 Generators with line to neutral power for excitation & regulation The following circuit gives power to the regulator module (A1): From neutral (T0) of stator (L6) to terminal (261). From terminal (26) through wire (26) to regulator power resistor (R4). Through regulator power resistor (R4) and wire (3) to regulator module (A1). Through regulator module (A1) to terminal (6). From terminal (6) of regulator module (A1) to potentiometer (R1) (voltage droop). From potentiometer (R1) (voltage droop) to rheostat (R2) (voltage level). From rheostat (R2) (voltage level) through wire (6). fuse (F1), thermal protector (TP) and wire (24) to terminal (24). From terminal (24) to the tapped connection of phase 2 of stator (L6).
