For upgrade Torque Control is
important check the connection the
current transformer (see fig below). Change the position the cables the
current transformers obtain correct
position necessary. careful how you
connect the cables from the thyristors.
18. the two cables each current
transformer are black use multimeter to
detect the right connection.
21. Mount the cables from the thermal switch
and current transformers the LV-Board.
19.
Be careful how you connect the cables
from the current transformers (correct
phase sequence). Mount the new HV-Board with the five
screws.
17. Mount the cables from the thyristors and
fans the HV-Board. The resistance
of the current transformer are between
0,2-6 ohm.16.
