Processor based control system for use with electrical equipment such as cookers, microwave ovens

摘要

The system keyboard 10 for function selection has the outputs monitored by a processor 14 to detect fault conditions and this either inhibits or activates switching stages 18 controlling power to the loads 20. When a fault is detected power is turned off. Operating information is also stored in a memory 16 and this is used by a duplicate peripheral processor 28 and is compared with measured analogue signals to maintain operation.
