Voltage Selection for CNC Fan
The output voltage can be set to 5V, 12V or 24V through a jumper. (MFAN and
FAN6 share the power supply VFAN6).
Note: Verify the fan's rated voltage before selecting to avoid damage. We are not
responsible for fans burnt due to incorrect voltage selection.
100K NTC or PT1000 Setting
When using 100K NTC, no jumpers need to be connected, the pull-up resistance
of TH0-TH3 is 4.7K 0.1%. When using PT1000, the pins indicated in the picture
below need to be connected via jumpers, parallel connection of 4.12K 0.1%
resistors, the pull-up resistance of TH0-TH1 is 2.2K. (Note: this method has a
much lower accuracy than the MAX31865 in reading temperature.)
