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.
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:
•
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.
After having restored the defaults, the 7 segment display will show the
number 88, the same as when fi rst starting the controller. This means that
the DEFAULT values have been restored correctly.

Important: after having confi gured the system, power down the
controller and power up again.

This solution is for obtaining the recommended confi guration for the
system. By responding to a series of questions, from screen to screen, the
user is guided in choosing the devices that are present. Once the guided
procedure is fi nished, the fi nal obtainable results can be viewed (report)
and, if the confi guration is correct, direct installation can be performed of
the parameters for pRack pR300T operation, including those associated
with the inputs and outputs as described in paragraph 4.4.
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 PR300T, carefully check the
settings made automatically by the software.
Tutorial: the following paragraph shows a confi guration example
using the Wizard for an installation with two suction lines.
4.3 Example of system confi guration using
the Wizard
This describes a possible example of Wizard-led confi guration for a type
of system like the one shown in the fi gure, with 2 suction lines and part
in high pressure (gas cooler and HPV, RPRV valves) on 3 diff erent control
boards:
