9.2.4 SYSTEM BEHAVIOR – REDUNDANT TEMPERATURE INPUTS
A temperature input is redundant if it is measured by multiple thermocouple devices (i.e., one created
temperature input (Temperature Wizard > Create Inputs Tab) is assigned to more than one temperature card
input slot (Temperature Wizard > Temp Modules Tab) either on the same card or on another card).
