TESTER FOR MIS-CONNECTION OF REFRIGERATOR

摘要

PURPOSE: A tester for the mis-connection of a refrigerator is provided to sense the mis-connection of a wire between a main controller controlling a compressor and the compressor. CONSTITUTION: A mis-connection sensing controller(160) decides if a mis-connection occurs according to the signals into input ports(IP1, IP2, IP3). The controller decides the state is normal when a low signal is fed into the first input port and the second input port and a high signal is fed into the third input port for more than a reference time. Thereby, the controller indicates the normal state and a mis-connection state on a lamp, and a tester is informed of the mis-connection state quickly.
