FDJY Jockey Pump Controllers

When six or twelve-lead delta connected jockey pump motors are started wye (star) connected, approximately 58% of line voltage is applied to each winding. 
The motor develops 33% of full-voltage starting torque and draws 33% of normal locked-rotor current from the line. 
After a 2 seconds time delay (during which the motor accelerates), it is reconnected for normal operation.
