FACTOry SETTING
Parameter legend:
(1) XD_SCaLE:
Defines the input values from the transducer block (input range of sensor) corresponding to 0% and
100% span values from the inside calculation of the aI function blocks.
the values set as the mass flow span, volume flow span, density span and temperature span are
stored in this parameter in the RCCt3/RCCF31.
Concentration span and net flow span can be set in this parameter under option /Cxx.
(2) out_SCaLE: output scaling parameter. Defines the output values corresponding to 0% and 100% span values
from the inside calculation of the aI function blocks.
(3) PV_FtIME: time constant of the damping function within the aI blocks is set to 0 s.
(4) L_tYPE:
Determines if the values passed by the transducer block to the aI block may be used directly (Direct)
or if the value is in different units and must be converted linearly (Indirect Linear) using the input range
defined by XD_SCaLE and the associated output range (out_SCaLE).
