(=NC)Ó. When backgauge moves forwards
and activates limit switch, it shows ÒOpenÓ
and stops backgaugeÕs forward motion. If the
actuator of limit switch is on or connector is
disconnected, the control board determines the
detection circuit is ÒOpenÓ and backgauge
can not operate forwards. (Backgauge can go
backwards.)

Board, Connector LayoutÓ.
