20. For upgrade Torque Control is
important check the connection the
current transformer (see fig below). Mount the cables from the thermal switch
and current transformers the LV-Board. Mount the new HV-Board with the five
screws.
Be careful how you connect the cables
from the current transformers (correct
phase sequence). Mount the cables from the thyristors and
fans the HV-Board.
21. Change the position the cables the
current transformers obtain correct
position necessary. The resistance
of the current transformer are between
0,2-6 ohm. careful how you
connect the cables from the thyristors.
