Starter
This starter type is a reduced voltage starter. When the start button is pressed, timing relay
TR is picked up and seals itself in. The 1S coil is also picked up which then picks up the 2S
coil. The 1S contacts configure the autotransformer windings into an open delta for two
winding or wye for three winding autotransformers. The 2S contacts bring the
autotransformer on line providing reduced voltage to the motor. When the timing relay TR
times out 1S and 2S drop out and then contactor coil R picks up and full voltage is applied
to the motor.
