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).
