2.13.6 PBS Thermistor

This is the temperature detection thermistor installed on the side of the fan (attached to the
power supply unit). If the environment around the power supply unit overheats because of
a fan or circuit abnormality, this thermistor shuts off the power. The power shut off control
is the same as the lamp thermistor
