RECTANGULAR BALER WITH DYNAMIC TESTING OF LOAD CELLS AND LIMP HOME MODE

摘要

Abstract of the DisclosureIn a rectangular baler wherein right and left conrodload cells measure the force applied to plungers for compactingcrop material, a microprocessor based control circuit monitors theloads registered by the load cells. The microprocessor producesoutput signals to control the baler in accordance with the loadssensed by the cells. On a stroke of the plunger, a one-quartersecond interval is toiled after one cell registers a load. If thesecond cell does not register a load within the interval it isassumed that it is faulty. In order to permit continued operationof the baler, the output of the good cell is assumed to be, and isused by the microprocessor as if it were the output of the faultycell.
