There is no published scheme for creating a star delta using Tesys U componentry but it can be creating by the addition of some non Tesys U parts, contactors etc.
It is also possible to construct a reversing star delta using 2 Tesys U stand alone reversing units LU6MB0** plus 2 additional contactors.
In both scenarios the Tesys U is upstream of the delta loop, therefore the maximum motor sizes are limited to 12A FLC and 32A FLC for LUB12 and LUB32 respectively.
Please see the attached documents for schematics of possible scheme.
These are functional schematic diagrams to illustrate how the control can be achieved. The installer remains responsible for ensuring all relevant local legislation and directives are met and that suitable circuit protection is provided.
