OPERATION
VSD Baseplate Temperature Load Limiting
VSD Baseplate load limiting helps protect the unit
from tripping on the high VSD Baseplate Temp Safety.
A system is permitted to load normally as long as the
VSD Baseplate temperature is below the VSD Baseplate
Temperature Cutout – 8°F. Between the VSD Baseplate
Temperature Cutout –8°F and the VSD Baseplate Tem-
perature Cutout – 4°F, loading is inhibited, even though
increased loading is required. Between the VSD Base-
plate Temperature Cutout – 4°F and the cutout, forced
unloading is performed every 2 seconds according to
TABLE 10 below:
