Abstract
A method of driving an automatic on-off valve for a water passageway uses the automatic on-off valve including an electromagnetic valve for opening and closing the water passageway, a sensor unit for detecting an object such as a man or a human hand and a control unit for controlling supply/cut-off of driving electric power supplied from a power supply to the electromagnetic valve in response to a signal transmitted from the sensor unit. The method comprises the steps of: permitting the control unit to control an operation of the electromagnetic valve in a normal state; manually supplying the electromagnetic valve with the driving power given from a manual driving unit connected to the electromagnetic valve; and thus forcibly driving the electromagnetic valve.
