Abstract
A controller is provided with a plurality of CPUs and temperature sensors disposed in the vicinity of the CPUs, individually. The CPUs reciprocally read temperature data detected by the temperature sensors. When the read temperature data exceed a predetermined threshold, it is determined that the CPUs are likely to undergo thermal runaway, and the CPUs are then stopped.
