Note : after having confi gured pRack pR300T, the power must be
turned off and back on in order to confi rm that the data is saved.
4.4 Advanced confi guration
Start up
Select Config.Item:
ADVANCED CONFIGURATION
It only defines the
structure of the plant
For very expert users
Fig. 4.p
This solution allows you to establish the confi guration for the pLAN
structure needed for correct operation of the system.
Once the procedure for choosing the various factors that infl uence the
fi nal confi guration is completed, the pRack pR300T software verifi es if the
pLAN confi guration is exact and shows the user interface for confi guring
the parameters that must be manually performed by the user.
Attention : this confi guration method is recommended only for
expert users, since all system parameters must be manually confi gured.
4.4.1 Associating the inputs and outputs
When using pre-confi gurations and the wizard, pRack PR300T can
automatically associate the board’s inputs and outputs with the various
functions.
For the wizard only, after having confi gured the lines, automatic association
can be chosen as an option. If choosing not to use this function, the I/Os
need to be confi gured manually, according to requirements.
The criteria applied for automatic association are described below.
Digital outputs
pRack PR300T assigns in order:
•
Compressor outputs
•
Fan outputs
•
Global alarm.
Digital inputs
pRack PR300T assigns in order:
•
High and low pressure switches (HP and LP)
•
Compressor alarms
•
Fan alarms
Note : pRack PR300T can also use certain analogue inputs as digital
inputs, nonetheless the common HP and LP pressure switches are always
associated with actual digital inputs.
Analogue inputs
pRack PR300T assigns in order:
•
Pressure or temperature control probes for 1 or 2 lines, according to the
settings made. The types of probe asSigned as default are 4…20 mA
or 0 to 5 V (fi rst 4…20 mA, then 0 to 5 V if necessary) for the pressure
probes, NTC for the suction temperature probes and HTNTC for the
condensing temperature probes;
•
Suction temperature probe on line 1: if possible this is associated with
input U3, otherwise the fi rst free input;
•
Discharge temperature probe on line 1;
•
Suction temperature probe on line 2;
•
Discharge temperature probe on line 2.
Analogue outputs
pRack PR300T assigns in order:
•
Compressor inverters for 1 or 2 lines;
•
Fan modulating devices.
