1 CD-KP for MULTIDRIVE and CD3000E
1.1 General description
CD-KP is a panel device allowing to display some operative parameters of thyristor units as
voltage, current, power, reference, alarms, etc.
CD-KP can be configured to select which parameter to display and is possible to execute
commands as start and stop of the connected unit, display and reset of alarms, to change
reference and ramp.
All the menus (exc ept the operator menu) can be protected by password to avoid accidental
change of configuration parameters by unauthorised personnel.
CD-KP has an isolated analog output 0÷10V/0÷20mA/4÷20mA to retransmit parameters’
value as voltage, power and reference.

0÷20mA, 4÷20mA, 0÷10V.
There is also an hardware configuration that must be
done: a jumper must be set near the rear terminals, as
showed in figures on the right.
If the output is configured as 0÷20mA or 4÷20mA, the
jumper must be set as in fig. A (current selection).
If the output is configured as 0÷10V, the jumper must

1.6.1 to display the menu items, the
parameters names or the process
variables.
Lower Display:
Used to display the parameters’ value
or the precess variables.
Plug-in connector:
It allows to connect a PC to the CDKP.
Error/Alarm display
E = communication error
A = Multidrive/CD3000E alarm
L/R key (Local/Remote):
If enabled, it allows to switch from
remote to local mode. It is also used
to save the settings of the
configuration menu.
Roll key:
Used to scroll the items in menus or
to confirm a selection.
Down key:
Used to decrease the selected parameter’s
value or to scroll down in the menus.
Up key:
Used to increase the selected parameter’s
value or to scroll up in the menus.
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.

By default, CDKP is configured to communicate with units at address 1 and baud rate 19200.
The variables displayed in operator menu are: average power (P32), average current (Arst
parameter), voltage and reference signal in percentage. All the menus are protected by
password with value 255.
1.9 Start-up
Before to supply the CD-KP check that the wiring is correct and verify the supply line voltage
value (120Vac or 240Vac). Automatically, the operator menu 1 will be displayed with power
value in upper display and reference value in lower display.
E
A
If an “E” is flashing in error/alarm display, there is a communication error, CDKP is not able to exchange data with thyristor unit. The user must verify:
- that CD-KP and thyristor unit have the same baud rate
- that the address called by CD-KP is the unit’s address
- that the polarities of RS485 link are correct
- that the thyristor unit is supplied and in ON condition.
If an “A” is flashing in error/alarm display, it means that CD-KP received an
alarm indication from the thyristor unit. The user must go in the operator
menu, scroll up to alarm sub-menu ( ALAr ), identify the alarm type and
remove its cause (see operator menu’s paragraph).
