In case of automatic starting controller's shaft is turned to a next position, and the current in electric engine is brought down to 170 to 180 amperes. The starting with less transfer currents is possible for a next position 125 A.
When the automatic starter's control shaft is rotated to the next step, and the electrical power to the engine decreases to between 170 and 180 amps, it now becomes feasible to start the next position using only 125 amps of current.
