CVAHU Controller Outputs
Table 16 lists the CVAHU Outputs for each controller model.
NOTE: The optional points Free1AO, Free2AO,
Free1AORev, Free2AORev are available in the
W7750C Model of CVAHU only. These enumerations
must be selected to use terminals 6,7 and 8 of
W7750C model. These outputs can be driven by
XL15A or XL15C, but since Free1 and Free2 are
digital in nature, XL15A and XL15C can only
command these points to ON or OFF. Hence, these
points can be driven only by digital outputs of Xl15A/
Xl15C loops.
