1.3 Confi guration of the system and
confi guration of the inputs and outputs
pRack pR300T has the same system confi guration management and
input and output confi guration management as the standard pRack.
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.
1.3.1
System confi gurations available
pRack pR300T can manage system confi gurations with up to 2 suction
lines (maximum 12 scroll or piston compressors for lines 1 and 2) and up
to 1 high pressure line (maximum 16 fans per line). When there are two
suction lines, the lines can be managed by the same pRack board or by
separate boards. The condenser line can be managed by the board that
manages the suction line, or by a separate board, in accordance with the
number of inputs/outputs available.
For each line, both suction and condensing, pRack pR300T can manage
a modulating device (inverter, Digital Scroll® compressor or compressor
with continuous control).
Example 1: 1 suction line with scroll or piston compressors, 1 high pressure
line:

Note: if connecting more than one pRack pR300 board in a pLAN,
mixed networks cannot be created combining Compact boards and S, M,
L boards, while mixed networks are possible using combinations of the
latter models only.
Important: all the boards connected to the pLAN must have the
same software revision.
