PROBLEM TO BE SOLVED: To carry out efficiently inspection. SOLUTION: A relay LCN is turned on, and relays LCU, LCV, LCW and LCP are sequentially turned on. Thus, a current can be supplied via free wheeling diodes DU2, DV2, DW2 and Dc2. A probe contact state can be detected by detecting this current state. |
