25.5.17 Temperature Inputs
Some thermocouple inputs are multi-purpose capable and have several configuration options. CHT5/
CHT6, GP6/GP7, MISC TEMP 1/MISC TEMP 2, and Oil Temp can be used for resistive based
temperature sensors. These inputs are configured by the GDU (refer to
for GDU 37X
systems and to
for GDU 4XX systems).
NOTE
If installing an ungrounded thermocouple to an Analog In input, a DC reference must be
added to the LO input. This can be accomplished by adding a resistance of 1 M
Ω
or less
between ground and the Analog In LO input that the ungrounded thermocouple is installed
on.
