26 MW-520 Application Developer's Guide
• MM2 is a sensor located on the EMC2 module too. This sensor is responsible
for the second 25% throttling, and its level can be adjusted using the relevant
software.
• The thermistor located on the main board (identical to the sensor which was
responsible for the temperature mechanism in previous MW-520 phases).
This sensor is responsible for hardware shutdown (in case of software hang),
and for the red temperature led activity. This sensor is not S/W adjustable.
The temperature control mechanism is described in the following chart:
