1.6.1
1.7 Frontal plug-in connector
The plug-in connector on front of CD-KP allows to put a PC in communication with a CD3000E
or MULTIDRIVE thyristor unit.
Usually, the thyristor unit is mounted in a cabinet and to have access to it the operator must
pay attention to high voltage or
stop the plant. Connecting the
configuration cable (supplied
separately) to the CDKP, it will
provide the physical link with the
thyristor unit releasing the control
on communication line. All the
displays of CD-KP will flash and the
control on serial link will be
released. In this condition, no
operation is possible on CDKP and
all keys are disabled.
Unplugging the configuration cable,
the CD-KP will return in its normal
working condition.
