Starter Functions
6.10 PART-WINDING AND DOUBLE-DELTA STARTERS
Sequence: Fig. 6.5
Connection: Fig. 6.18
Current Transfer: Available
The part-winding starter is used on motors with two
stator windings and the double-delta starter has a delta
winding that is parallel connected during running.
START1 or START2 initiates the starting sequence by
activating Starter RLYA. Starter RLYB activates after the
Stage1 Delay.
Both starters require two FLA settings. FLA Rating 2
is the full-load current for the starting connection and
FLA Rating is the full-load current for the running
connection.
