3.2.7 Overtemperature trips
The MicroFlex contains internal temperature sensors that will cause it to trip and disable if the
temperature exceeds 80°C on the 1A or 3A models, or 75°C on the 6A and 9A models. This
limit can be read using the
TEMPERATURELIMITFATAL keyword - see the Mint help file for
details.
