Mode of Operation
The output relay is normally
in the neutral centre posi-
tion. When the power supply
is applied, the relay switch-

and the star period starts.
At the end of the set time
period, the relay returns to
the neutral centre position
and the set delay between
star
starts.
At the end of the star to
delta delay (adjustable from
