Do the ATS22 soft starters have a internal shorting bypass contactor?

Issue:
Do the ATS22 soft starters have a internal shorting bypass contactor?

Product Line:
Altistart ATS22

Environment:
All

Cause:
Wants to know if the open type ATS22 have an internal shorting contactor to bypass the soft starter after its up to speed.

Resolution:
Yes.  It is a shorting contactor that closes when the motor is up to full speed.  The purpose is to give the current a path around the SCRs.  This prolongs the life of the SCRs and reduces heat produced by the soft starter.
Note that this contactor is not for full voltage across the line starting without the soft starter.
