As shown in the illustrated reduced voltage three phase squirrel cage induction motor controller, what is the functional purpose of the "CR" relay? See illustration EL-0116.
A
It is used to establish the time delay associated with initial startup in delta configuration and transitioning into wye configuration for run.
B
It is used to establish the time delay associated with initial startup in wye configuration and transitioning into delta configuration for run.
C
It is used to establish the actual length of time of closed transition when the motor is connected in both wye and delta configurations simultaneously.
D
It is used to establish the actual length of time of open transition when the motor is briefly disconnected from line.
