4.1 Starting the fi rst time
After having correctly installed pRack, a number of preliminary operations
are required to confi gure the installation.
Tutorial: the pRack pR300 confi guration procedure varies according
to the complexity of the installation:
A. systems with only one board and maximum one external terminal.
In this case, simply connect the terminal (if not built-in), power up the
board and select one of the confi guration solutions described below.
B. systems with more than one board in pLAN or two external
terminals. IIn this case, the additional operations described in
Appendix A. 2 need to be completed before proceeding with
confi guration.
The procedure for confi guring an installation described below is the same
for all system confi gurations that feature just one pRack pR300 board,
and for system confi gurations with more than one board connected in
a pLAN.
When fi rst starting the pRack pR300 board, after waiting around 1 minute,
a screen is shown for choosing the language used to display the program
(English or Italian).
Press ENTER ( ) to change the language displayed, while pressing ESC
displays the following screen.
Note:
•
If no option is chosen within a time set by parameter and visible on the
screen, the current language remains selected.
•
pRack pR300 is available as standard with English and Italian
languages loaded on board. Other languages are available at
ksa.carel.com that can be loaded onto the control using the pRack
Manager software, following the procedure described in Chap. 10.
After having selected the user interface language, the pRack pR300
software shows a screen for choosing between three possible system
confi guration solutions, as follows:
•
Pre-confi gurations
•

Wizard

•
Advanced confi guration.
Important:
•
after having confi gured the system, the confi guration can be modifi ed,
it can be modifi ed by repeating the same procedure, making sure the
Carel default values have been reset as described in paragraph 6.8.2.
•
after having confi gured the system, power down the controller and
power up again.

4.1.1 Pre-confi gurations
Start up
Select Config.Item:
PRE-CONFIGURATION
Choose one from the
configuration in the
list
This solution is used to choose between fourteen confi gurations pre-
loaded in the pRack pR300 software. For the description of the pre-
confi gurations see the table below, while for the complete description of
each confi guration see Appendix A1.
pRack pR300 automatically confi gures the inputs and outputs as described
in paragraph 4.1.4; for details on the inputs and outputs associated with
each pre-confi guration, see the quick guide code +040000070.
4.1.2 Wizard
Start up
Select Config.Item:
Answer the questions
to have a fully
configuration
This solution is used to obtain the recommended confi guration for the
specifi c installation. By responding to a series of questions, screen by
screen, the user is guided through the selection of the devices present.
Once the guided selection procedure has been completed, the end result
(report) is shown, and if the confi guration is suitable the parameters to
start operation of the pRack pR300 can be installed directly, including
those associated with the inputs and outputs as described in parag. 4.1.4.
Note: after having confi gured the parameters using the Wizard, the
confi guration can be modifi ed manually, within the context of the
selected system confi guration.
Important: before starting the pRack pR300, carefully check the
settings made automatically by the software.
Tutorial: Appendix A.3 shows a confi guration example using the
Wizard for an installation with two suction lines.
