1.3 Confi guration of the system and
confi guration of the inputs and outputs
pRack pR300 has the same system, input and output confi guration
management as the standard pRack pR100. It is available 22
confi gurations, but it is more ultilised those described in Appendix A.1.
Note: each input/output is completely confi gurable with the only
requirements being those set by the system confi guration. For
example, the suction pressure probe on line 1 can be arbitrarily confi gured
to any one of the analog inputs in the pLAN control board with address 1
compatible with the type of probe.
Refer Cap. 4, to have more ionformation about selection of confi guration
system and pre-confi guration and see Appendix A.1.
1.3.1 System confi gurations available
pRack pR300 can manage system confi gurations with up to 2 suction lines
(maximum 12 scroll or piston compressors for lines 1 and 2, maximum 2
screw compressors for line 1 and maximum 1 BitzerCRII compressor per
line), up to 2 condenser lines (maximum 16 fans per line). When there
are two suction lines, the 2 lines can be managed by the same pRack
board or by separate boards. The condenser lines can be managed by
the board controls the suction lines or by separate boards, depending on
the number of inputs/outputs available. For each suction and condenser
line, pRack pR300 can manage a modulating device (inverter, Digital
Scroll® compressor, compressor with continuous control or BitzerCRII
compressor). pRack pR300 manages up to 1 line with screw compressors,
and the board can control up to 2 compressors.
Some examples of managed system confi gurations are described below,
while for the complete list of confi gurations and its features refer to
Appendix A1.

Note: nel caso di collegamento in pLAN di più schede pRack pR300,
non è possibile realizzare reti miste con schede di taglia Compact insieme
a schede di tipo S, M, L, mentre risultano possibili reti miste che utilizzino
combinazioni di queste ultime.
Important: all the boards connected to the pLAN must have the
same software revision.
