Abstract: In electrically heated screed assemblies, elements that are prone to failure are the temperature sensors. Typically, each screed plate has a single temperature sensor. When one temperature sensor fails, the controller will look for a working temperature sensor amongst the other screed plates and if more than one temperature sensor is working, the controller will choose the most relevant temperature sensor and use the data from the working temperature sensor to operate the resistive heating elements on the screed plate with the non-functional temperature sensor. If the temperature sensor on an outer screed plate fails, the controller will look to the other outer screed plate temperature sensor for data for purposes of operating the resistive heating elements on the outer screed plate with a broken temperature sensor.
