Unit-Mounted Wye-Delta Starter (Optional)
The 19XL machine may be equipped with a wye-delta starter mounted on the unit. This
starter is intended for use with low-voltage motors (under 600 v). It reduces the starting current
inrush by connecting each phase of the motor windings into a wye configuration. This occurs
during the starting period when the motor is accelerating up to speed. After a time delay, once
the motor is up to speed, the starter automatically connects the phase windings into a delta
configuration.
