    摘要: In a rectangular baler (11) a microprocessor (10) based control circuit monitors the loads registered by right-hand and left-hand conrod load cells (12, 14), the conrod load cells measuring the force applied to a plunger for compacting crop material. The microprocessor (10) produces output signals to control the baler (11) in accordance with the loads sensed by the cells (12, 14). On a stroke of the plunger, a predetermined interval, for example one-quarter second, is tolled after one cell registers a load. If the second cell does not register a load within that interval it is assumed to be faulty. In order to permit continued operation of the baler, the output of the good cell is assumed to be, and is used by the microprocessor as if if were, the output of the faulty cell.
