3.2.6 Overtemperature trips
The MicroFlex e100 contains internal temperature sensors that will cause it to trip and disable if
the temperature exceeds 80°C on the 3A model, 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.
