The LEYD/A sole function is to control the changeover of a motor connected in Star configuration over to Delta. Typically the timer is used in conjunction with several contactors connected between the supply and the motor.
An adjustable time delay allows a period to be set that the motor will run in the Star configuration and being adjustable caters for various sizes of the motor. A selectable "dwell time" adjustment sets the changeover period when switching from Star over to Delta takes place.
This demonstration shows how the product operates along with setting the timer up.
