Table 1-6.—Wrong Stator Connections, Rotor Wiring Correct

1-59 Table 1-6.—Wrong Stator Connections, Rotor Wiring Correct SETTING OR CONDITIONS INDICATION TROUBLE TX set to 0º and rotor turned smoothly counterclockwise TR indication is wrong, turns clockwise from 240º S1 and S2 stator connections are reversed TR indication is wrong, turns clockwise from 120º S2 and S3 stator connections are reversed TR indication is wrong, turns clockwise from 0º S1 and S3 stator connections are reversed TR indication is wrong, turns counterclockwise from 120º S1 is connected to S2, S2 is connected to S3, and S3 is connected to S1 TR indication is wrong, turns counterclockwise from 240º S1 is connected to S3, S2 is connected to S1, and S3 is connected to S2 Table 1-7.—Wrong Stator and/or Reversed Rotor Connections SETTINGS OR CONDITIONS INDICATION TROUBLE TX set to 0º and rotor turned smoothly counterclockwise TR indication is wrong, turns counterclockwise from 180º Stator connects are correct, but rotor connections are reversed TR indication is wrong, turns clockwise from 60º Stator connections S1 and S2 are reversed, and rotor connections are reversed TR indication is wrong, turns clockwise from 300º Stator connections S2 and S3 are reversed, and rotor connections are reversed TR indication is wrong, turns clockwise from 180º Stator connections S1 and S3 are reversed, and rotor connections are reversed TR indication is wrong, turns counterclockwise from 300º S1 is connected to S2, S2 is connected to S3, S3 is connected to S1, and rotor connections are reversed TR indication is wrong, turns counterclockwise from 60º S1 is connected to S3, S2 is connected to S1, S3 is connected to S2, and rotor connections are reversed In a control system, the trouble may be slightly more difficult to isolate. However, the existence of trouble is readily indicated when the system does not properly respond to an input order. For control systems, it is easier to locate the trouble by using a synchro tester or by checking the operating voltages.
