Step vs. Slope Module Compatibility
Matching Control
Units With LVD/
Thermal Units
In a -48V plant, keying does not prevent mixing control units and LVD/
thermal boards with different temperature compensation conventions in
the same plant; that is, using slope compensation units with those
equipped with step compensation. This allows units in the field to be
upgraded from step to slope compensation without modification to the
CPS shelf.
Table 2-B matches control units with the proper LVD/thermal unit.
