Electric screed heat control system and method of heating screed plates
In electrically heated screed assemblies, elements that are prone to failure are the temperature sensors (88). Typically, each screed plate (36) has a single temperature sensor (88). When one temperature sensor (88) fails, the controller (70) will look for a working temperature sensor (88) amongst the other screed plates (36) and if more than one temperature sensor (88) is working, the controller (70) will choose the most relevant temperature sensor (88) and use the data from the working temperature sensor (88) to operate the resistive heating elements (51) on the screed plate (36) with the non-functional temperature sensor (88). If the temperature sensor (88) on an outer screed plate (36) fails, the controller (70) will look to the other outer screed plate (36) temperature sensor (88) for data for purposes of operating the resistive heating elements (51) on the outer screed plate (36) with a broken temperature sensor (88). Similarly, if the temperature sensor (88) on an inner or central screed plate (36) fails, the controller (70) will look to a neighboring screed plate (46) with a working temperature sensor (88) for data for purposes of operating the inner or center screed plate (36) with the broken temperature sensor (88). The controller (70) will generate signals for the operator to replace the failed temperature sensor (88).
