(1) For easier adjustment, it is preferable to set the time delay between the maximum value in the range and one tenth
of this value.
Example: RE8-PE11BUTQ timing range 0.1 s…10 s, recommended use 1 s…10 s.
(2) Correct operation of the star-delta starter is only possible if the wiring scheme on page 2/41 is strictly complied with.
