SIGNAL is defined as the angle through which a transmitter rotor is mechanically turned. This term
has the same meaning as "transmitter's mechanical input."
RECEIVER ROTATION may be in a direction opposite to that desired. When it is necessary to
reverse receiver rotation, reverse the S1 and S3 connections on either the synchro transmitter or the
synchro receiver. The causes both synchro rotors to turn through the same angle but in opposite
directions.
REVERSED ROTOR CONNECTIONS are common problems in new or modified synchro
systems and should not be confused with the deliberate reversal of the stator connections. The reversal of
the R1 and R2 connections on a synchro rotor causes a 180º error between the synchro transmitter and the
synchro receiver, but the direction of rotor rotation still remains the same.
